The definition of what constitutes a healthy diet is continually shifting to reflect the evolving understanding of the roles that different foods, essential nutrients, and other food components play in health and disease. A large and growing body of evidence supports that intake of certain types of nutrients, specific food groups, or overarching dietary patterns positively influences health and promotes the prevention of common non-communicable diseases (NCDs). Greater consumption of health-promoting foods and limited intake of unhealthier options are intrinsic to the eating habits of certain regional diets such as the Mediterranean diet or have been constructed as part of dietary patterns designed to reduce disease risk, such as the Dietary Approaches to Stop Hypertension (DASH) or Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets. In comparison with a more traditional Western diet, these healthier alternatives are higher in plant-based foods, including fresh fruits and vegetables, whole grains, legumes, seeds, and nuts and lower in animal-based foods, particularly fatty and processed meats. To better understand the current concept of a “healthy diet,” this review describes the features and supporting clinical and epidemiologic data for diets that have been shown to prevent disease and/or positively influence health. In total, evidence from epidemiological studies and clinical trials indicates that these types of dietary patterns reduce risks of NCDs including cardiovascular disease and cancer.

1. Introduction

Non-communicable diseases (NCDs) such as cardiovascular disease, cancer, chronic respiratory diseases, diabetes, obesity, and cognitive impairment are among the leading causes of death and disability throughout the world, affecting populations in developed as well as developing countries [ 1 ]. Although there are established genetic and environmental contributors to NCD risk, modifiable lifestyle-related factors play a large role at the individual level [ 2 , 3 , 4 ]. Dietary choices, for example, contribute to the risk for developing hypertension, hypercholesterolemia, overweight/obesity, and inflammation, which in turn increase the risk for diseases that are associated with significant morbidity and mortality, including cardiovascular disease, diabetes, and cancer [ 5 ]. Indeed, the marked rise in chronic NCDs has a causal link to global dietary patterns that are becoming increasingly Westernized [ 6 ], being characterized by high levels of fatty and processed meats, saturated fats, refined grains, salt, and sugars but lacking in fresh fruits and vegetables.

In recognition of the importance of the diet as a determinant of disease risk, the World Health Organization (WHO) Global Action Plan for the Prevention and Control of Noncommunicable Diseases includes strategies for addressing unhealthy diet patterns among its initiatives directed at reducing behavioral risk factors; the other components comprise physical inactivity, tobacco use, and harmful alcohol use [ 1 ]. Dietary changes recommended by WHO include balancing energy intake, limiting saturated and trans fats and shifting toward consumption of unsaturated fats, increasing intake of fruits and vegetables, and limiting the intake of sugar and salt. Many of these dietary targets naturally occur in regional diets such as the Mediterranean diet [ 7 ] or are included as part of evidence-based diets designed to reduce disease risk, such as the Dietary Approaches to Stop Hypertension (DASH) [ 8 ] or Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) [ 9 ] diets. To better understand the current concept of a “healthy diet”, this narrative review describes the features and supporting clinical and epidemiologic data for diets that align with the general WHO guidance and have been shown to prevent disease and/or positively influence health.

2. Components of a Healthy Diet and Their Benefits

A healthy diet is one in which macronutrients are consumed in appropriate proportions to support energetic and physiologic needs without excess intake while also providing sufficient micronutrients and hydration to meet the physiologic needs of the body [ 10 ]. Macronutrients (i.e., carbohydrates, proteins, and fats) provide the energy necessary for the cellular processes required for daily functioning [ 11 ]. Micronutrients (i.e., vitamins and minerals) are required in comparatively small amounts for normal growth, development, metabolism, and physiologic functioning [ 12 , 13 ].

Carbohydrates are the primary source of energy in the diet and are found in the greatest abundance in grains, fruits, legumes, and vegetables [ 14 ]. In terms of deriving a health benefit, whole grains are preferred over processed grains, the latter having been stripped of germ and bran during the milling process, resulting in lower amounts of fiber and micronutrients [ 15 ]. Meta-analyses of prospective cohort studies have linked increased whole-grain intake to a reduced risk of coronary heart disease, stroke, cardiovascular disease, and cancer, as well as to the decreased risk of mortality due to any cause, cardiovascular disease, cancer, respiratory disease, diabetes, and infectious disease [ 15 , 16 , 17 ]. Fresh fruits and vegetables supply energy as well as dietary fiber, which promotes the feeling of satiety and has positive effects on gastrointestinal function, cholesterol levels, and glycemic control [ 18 ]. In addition, fresh fruits and vegetables are key sources of phytochemicals (e.g., polyphenols, phytosterols, carotenoids), which are bioactive compounds believed to confer many of the health benefits associated with fruit and vegetable consumption [ 19 ]. The mechanistic effects of these various phytochemicals are unclear but include their antioxidative properties, as well as their role in regulating nuclear transcription factors, fat metabolism, and inflammatory mediators. For example, flavonoids have been shown to increase insulin secretion and reduce insulin resistance, suggesting that these phytochemicals provide some benefits in obesity and diabetes [ 20 ]. Additionally, polyphenols interact with gastrointestinal microbiota in a bi-directional manner by enhancing gut bacteria and being metabolized by these bacteria to form more bioactive compounds [ 20 ]. Fruit and vegetable intake has been shown to inversely correlate with the risk of NCDs, including hypertension [ 21 ], cardiovascular disease [ 22 , 23 ], chronic obstructive pulmonary disease [ 24 ], lung cancer [ 25 ], and metabolic syndrome [ 26 ].

Dietary proteins provide a source of energy as well as amino acids, including those that the human body requires but cannot produce on its own (i.e., essential amino acids). Dietary proteins are derived from both animal (meat, dairy, fish, and eggs) and plant (legumes, soya products, grains, nuts, and seeds) sources, with the former considered a richer source due to the array of amino acids, high digestibility, and greater bioavailability [ 27 ]. However, animal-based sources of protein contain saturated fatty acids, which have been linked to cardiovascular disease, dyslipidemia, and certain cancers. Although the mechanisms are unclear, red meat, and processed meat in particular, have been associated with an increased risk of colorectal cancer [ 28 , 29 ]. Animal-derived proteins also increase the dietary acid load, tipping the body’s acid-base balance toward acidosis [ 30 , 31 ]. The increased metabolic acid load has been linked to insulin resistance, impaired glucose homeostasis, and the development of urinary calcium stones [ 30 , 31 ].

Adequate dietary protein intake is important for maintaining lean body mass throughout the life span. In older adults, protein plays an important role in preventing age-related loss of skeletal muscle mass [ 32 ], preserving bone mass, and reducing fracture risk [ 33 ]. For older individuals not obtaining adequate protein from their diets, supplementation with amino acids can improve strength and functional status [ 34 ].

Fats (or lipids) are the primary structural components of cellular membranes and are also sources of cellular energy [ 35 ]. Dietary fats fall into 4 categories: monounsaturated fats, polyunsaturated fats, saturated fats, and trans fats. The fat content of food is generally an admixture of these different types [ 35 ]. Unsaturated fats are found in a variety of foods, including fish, many plant-derived oils, nuts, and seeds, whereas animal products (and some plant-derived oils) contribute a larger proportion of saturated fats [ 35 , 36 ]. Trans fats found in foods are predominantly the result of processing vegetable oils but are also present in small quantities in animal products (i.e., ruminant trans fats from cows, sheep, and goats) [ 35 , 36 ]. Among the types of dietary fats, unsaturated fats are associated with reduced cardiovascular and mortality risks, whereas trans fats and, to a lesser degree, saturated fats are associated with negative impacts on health, including increased mortality risk [ 36 , 37 ]. Two families of polyunsaturated fatty acids, omega-3 and omega-6, are described as essential fatty acids, because they are required for normal growth and reproduction but are not produced by the body and, therefore, must be obtained from dietary sources [ 10 ]. Omega-3 fatty acids, in particular, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), have been widely studied for their potential health benefits, with evidence suggesting positive effects including cardioprotection, preventing cognitive decline, reducing inflammation, sustaining muscle mass, and improving systemic insulin resistance [ 38 , 39 , 40 ]. Seafood, especially oily fish, provides EPA and DHA, and supplements are widely available for those not meeting recommended intakes with diet alone [ 41 , 42 ]. Nuts and some seeds and plant oils provide alpha-linolenic acid, the major plant omega-3 fatty acid [ 43 ].

Although required in trace amounts compared with macronutrients, micronutrients are necessary for normal growth, metabolism, physiologic functioning, and cellular integrity [ 12 , 13 ]. The shift from whole foods to processed, refined foods has reduced the micronutrient quality of the modern Western diet [ 44 ]. Vitamin and mineral inadequacies have been implicated in cellular aging and late-onset disease, as scarcity drives chronic metabolic disruption. Keeping with these observations, adequate dietary intake of, or supplementation with, micronutrients that have antioxidant properties (e.g., vitamins A, C, and E, copper, zinc, and selenium) has been suggested as a means to reduce the risk for and progression of age-related diseases [ 45 ].

Water is the principal component of the body, constituting the majority of lean body mass and total body weight [ 13 ]. Water not only provides hydration but also carries micronutrients, including trace elements and electrolytes [ 46 , 47 ]. Drinking water may supply as much as 20% of the daily recommended intake of calcium and magnesium [ 47 ]. Our understanding of water requirements and water’s effect on health and disease is limited, although the global increase in intake of high-calorie beverages has refocused attention on the importance of water for maintaining health and preventing disease [ 46 ].

3. Common Health-Promoting Dietary Patterns

Based on our understanding of nutritional requirements and their likely health impacts as described above, healthy dietary patterns can be generally described as those that are rich in health-promoting foods, including plant-based foods, fresh fruits and vegetables, antioxidants, soya, nuts, and sources of omega-3 fatty acids, and low in saturated fats and trans fats, animal-derived proteins, and added/refined sugars [ 48 ]. Patterns such as these are naturally occurring in certain regions of the world and rooted in local/regional tradition and food sources, as is the case for the traditional Mediterranean and Asian diets. Healthy dietary patterns have also been developed based on studies of nutrient intake and subsequent health measures or outcomes (e.g., the DASH [ 8 ] and MIND [ 9 ] diets) that share some common characteristics ( Figure 1 ).

A generalized healthy diet and lifestyle pyramid.

3.1. Mediterranean Diet

The Mediterranean diet is based on components of the traditional dietary patterns of Euro-Mediterranean countries and encompasses not only the types of foods consumed and their relative contributions to daily nutrient intake, but also an approach to eating that is cognizant of how foods are sourced (e.g., sustainability and eco-friendliness), cooked, and eaten, as well as lifestyle considerations such as engaging in regular physical activity, getting adequate rest, and participating in fellowship when preparing and sharing meals [ 7 ]. Within the core framework of the Mediterranean diet, variations based on geography and culture are reflected in the emphasis on the inclusion of traditional and local food products. The primary basis of daily meals in the Mediterranean diet is cereals such as whole-grain bread, pastas, couscous, and other unrefined grains that are rich in fiber and a variety of fruits and vegetables of different colors and textures that are high in micronutrients, fiber, and phytochemicals ( Table 1 ) [ 7 , 9 , 49 , 50 , 51 , 52 ]. Dairy products, preferably low-fat yogurt, cheese, or other fermented dairy products, are recommended daily in moderation as a source of calcium, which is needed for bone and heart health. Olive oil serves as the primary source of dietary lipids and is supplemented with olives, nuts, and seeds. Water (1.5–2.0 L/day or ~8 glasses) is recommended as the main source of hydration, whereas wine and other fermented alcoholic beverages are generally permitted in moderation, to be consumed with meals. Fish, white meat, and eggs are the primary sources of protein; red meat and processed meats are consumed less frequently and in smaller portions. Legumes are also a preferred source of plant-based proteins [ 7 ].

The health benefits of the Mediterranean diet were first described in 1975 by Ancel Keys, who observed a reduction in cardiovascular disease risk among populations whose nutritional model was consistent with practices of peoples from the Mediterranean Basin [ 53 ]. Since that time, research has revealed beneficial effects of the Mediterranean diet on a number of NCDs and related health measures, including cardiovascular and cerebrovascular disease [ 54 ], cancer [ 55 ], glycemic control [ 56 ], and cognitive function [ 57 , 58 ]. Although publication of a key intervention study (Prevención con Dieta Mediterránea; PREDIMED) conducted at multiple sites across Spain and evaluating the Mediterranean diet for the primary prevention of cardiovascular disease was retracted due to irregularities in randomization [ 59 ], a subsequent analysis adjusting for these issues reported a consistent positive effect of adhering to a Mediterranean diet supplemented with olive oil or nuts compared with a reduced-fat diet [ 59 ]. Substudies of PREDIMED have also shown that, compared with a low-fat control diet, the Mediterranean diet supplemented with olive oil or nuts is associated with a 30% reduced risk of major cardiovascular risk events [ 59 ] and reductions in systolic blood pressure (SBP) and diastolic blood pressure (DBP) of 5.8–7.3 mmHg and 3.3–3.4 mmHg, respectively [ 60 ]. In addition, cardiovascular factors such as mean internal carotid artery intima-media thickness (−0.084 mm; p < 0.05) and maximum plaque height (−0.091 mm; p < 0.05) are improved with the Mediterranean diet supplemented with nuts [ 61 ]. Greater intake of polyphenols (phytochemicals found in fruits, vegetables, tea, olive oil, and wine) correlated with a 36% reduced risk of hypertension ( p = 0.015) [ 62 ] and improvements in inflammatory biomarkers related to atherosclerosis (i.e., interleukin [IL]-6, tumor necrosis factor-alpha, soluble intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and monocyte chemotactic protein-1; p < 0.05 for each), as well as in high-density lipoprotein cholesterol (HDL-C; p = 0.004) [ 62 , 63 ].

3.2. Dietary Approaches to Stop Hypertension (DASH)

The DASH diet derives its name from the Dietary Approaches to Stop Hypertension study, which evaluated the influence of dietary patterns on blood pressure [ 8 ]. Patients who consumed a diet that was rich in fruits, vegetables, and low-fat dairy and that included a reduced amount of saturated and total fat and cholesterol experienced significantly greater reductions in blood pressure than patients who consumed a control diet that was similar in composition to a typical American diet (difference in SBP/DBP, −5.5/−3.0 mmHg; p < 0.001) or a diet rich in fruits and vegetables with a reduced amount of snacks and sweets (−2.7/−1.9 mmHg; p ≤ 0.002). All 3 diets had a sodium content of 3 g per day. A subsequent study (DASH-Sodium) that explored the DASH diet or a control diet in combination with varying levels of sodium intake (high, intermediate, and low) found that the DASH diet significantly reduced SBP during the high, intermediate, and low sodium intake phases of both diets (high: −5.9 mmHg; p < 0.001; intermediate: −5.0 mmHg; p < 0.001; low: −2.2 mmHg; p < 0.05) [ 64 ]. The DASH diet also significantly reduced DBP versus the control diet during the high (−2.9 mmHg; p < 0.001) and intermediate (−2.5 mmHg; p < 0.01) sodium intake phases but not during the low intake phase (−1.0 mmHg). Although reducing sodium intake also significantly reduced blood pressure in the control diet group ( p < 0.05), the low sodium phase of the DASH diet elicited significant decreases in SBP/DBP of −8.9/−4.5 mmHg ( p < 0.001 for each) compared with high sodium intake phase of the control diet.

Subsequent controlled trials, as a whole, support the results of the DASH and DASH-Sodium studies in terms of blood pressure reduction. Moreover, these studies expanded the positive impacts of the DASH diet to include improvements in other cardiovascular risk factors or comorbidities (e.g., low-density lipoprotein cholesterol [LDL-C], total cholesterol, overweight/obesity, and insulin sensitivity) [ 65 , 66 , 67 , 68 ] and reductions in adverse outcomes such as development of cardiovascular disease, coronary heart disease, stroke, heart failure, metabolic syndrome, and diabetes (including improved pregnancy outcomes in women with gestational diabetes) [ 68 , 69 , 70 , 71 , 72 ]. Meta-analyses of studies using the DASH diet have demonstrated that LDL-C is significantly reduced by −0.1 mmol/L ( p = 0.03) [ 65 , 68 ], total cholesterol by −0.2 mmol/L ( p < 0.001) [ 65 , 68 ], body weight by −1.42 kg ( p < 0.001) [ 66 , 68 ], and fasting insulin by −0.15 μU/mL ( p < 0.001) [ 65 , 66 , 67 , 68 ]. With the DASH diet, the risk of cardiovascular disease is reduced by 20%, stroke by 19%, and heart failure by 29% ( p < 0.001 for each) [ 69 , 71 ]. The overall risk of diabetes is reduced by 18% [ 68 ], and children and adolescents with higher DASH scores (i.e., those whose diets included the highest intakes of fruits, vegetables, nuts, legumes, low-fat dairy, and whole grains) were at 64% lower risk of developing metabolic syndrome than those with the lowest DASH scores ( p = 0.023) [ 71 ]. Furthermore, rates of cesarean section decreased by 47% [ 72 ], incidence of macrosomia (birth weight > 4000 g) decreased from 39% to 4% ( p = 0.002) [ 70 ], and significantly fewer women experienced gestational diabetes that required insulin therapy on the DASH diet (23%) compared with the control diet (73%; p < 0.0001) [ 70 ].

The dietary pattern derived from the DASH study emphasizes the consumption of an array of vegetables (including colorful varieties, legumes, and starchy vegetables), fruits, fat-free or low-fat dairy products, whole grains, and various protein sources (e.g., seafood, lean meats, eggs, legumes, nuts, seeds, and soya) ( Table 1 ) [ 49 ]. Limited consumption of added sugars (< 10% of calories per day), saturated fats (< 10% of calories per day), sodium (< 2300 mg/day), and alcohol (≤ 1 drink per day for women and ≤ 2 drinks per day for men) is suggested. In addition, further reductions in blood pressure may be achievable by further reducing sodium intake, although practical challenges may limit the ability to achieve sodium intake of 1200 mg or less per day [ 49 ].

3.3. Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND)

The MIND diet combines elements of the Mediterranean and DASH diets with the goal of sustaining cognitive health throughout older age [ 9 ]. Both the Mediterranean and DASH diets have been individually linked to positive cognitive outcomes, including the prevention of cognitive decline or impairment and better cognitive performance [ 73 , 74 , 75 ]. Two high-quality cohort studies have reported associations between adherence to the MIND diet and a 53% lower risk for developing Alzheimer’s disease ( p = 0.002 for linear trend) [ 50 ] and slower declines in cognitive functioning, both overall and within specific cognitive domains (e.g., episodic, semantic, and working memory and perceptual speed and organization), such that the highest adherence rates to the MIND diet were associated with cognitive function equivalent to being 7.5 years younger [ 50 , 76 ]. Interestingly, even modest adherence to the MIND diet was associated with a 35% risk reduction for Alzheimer’s disease versus the lowest adherence group ( p = 0.002 for linear trend), whereas high adherence was needed to demonstrate 54% and 39% risk reductions with the Mediterranean and DASH diets, respectively; high adherence to the Mediterranean and DASH diet showed a statistically significant benefit [ 50 ].

The MIND diet focuses on increasing the intake of fresh fruits and vegetables and emphasizes brain-healthy foods such as green leafy vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil, and wine in moderation ( Table 1 ) [ 9 , 50 ]. Additionally, foods that are thought to be unhealthy for the brain, such as red meats, butter/margarine, cheese, pastries, sweets, and fried or fast food, are limited [ 9 ]. The specificity regarding the types of foods on the healthy and unhealthy lists differentiates MIND from the Mediterranean or DASH diets [ 50 ].

3.4. Nordic Diet

Iterations of a Nordic diet (e.g., the healthy Nordic diet, New Nordic Diet) arose from the desire to translate the Mediterranean, DASH, and other health-promoting diets into a regionally tailored dietary pattern that uses traditional, local Nordic foods and would be attractive to the public, sustainable, and eco-friendly [ 77 , 78 ]. Overarching tenets of the New Nordic Diet are to consume more (1) calories from plant sources and fewer from animal sources, (2) foods from seas and lakes, and (3) foods from the wild countryside [ 78 , 79 ]. A generalized Nordic dietary pattern would include green leafy vegetables, other vegetables, fruits, fish and seafood, potatoes, berries, whole grains (e.g., wheat, rye, oats, barley), nuts, low-fat dairy products, rapeseed, sunflower, and/or soya oils and limited intake of fresh red meat and sugar [ 78 , 80 ]. Specific dietary recommendations based on the NORDIET clinical trial are presented in Table 1 [ 51 ].

The randomized, controlled NORDIET study compared a healthy Nordic diet with a control diet (the participant’s usual Western diet) [ 77 ]. Over 6 weeks, the Nordic diet improved the lipid profile (including a 0.98 mmol/L reduction in total cholesterol [ p < 0.0001] and a 0.83 mmol/L reduction in LDL-C [ p < 0.001]), lowered SBP by 6.6 mmHg ( p = 0.008), and improved insulin sensitivity (homeostatic model assessment-insulin resistance decreased 0.11; p = 0.01) compared with the control diet. Those on the Nordic diet also experienced a 3.0 kg decrease in body weight ( p < 0.001) despite food being available ad libitum.

Results from subsequent studies conducted using Nordic diet variations are consistent with those from studies with the NORDIET study, demonstrating improvements relative to the control diet in blood lipid profile (LDL-C/HDL-C ratio, −0.15; p = 0.046) [ 81 ], inflammation (IL-1 receptor antagonist, −84 ng/L; p < 0.001) [ 81 ], blood pressure (DBP, −4.4 mmHg ( p = 0.001), and mean arterial pressure (−4.2 mmHg; p = 0.006) among patients with metabolic syndrome [ 82 ] and weight loss (−3.22 kg; p < 0.001) [ 83 ] and blood pressure reduction (SBP/DBP, −5.13/−3.24 mmHg; p < 0.05) in individuals with obesity [ 83 ]. Compared with baseline values, one study demonstrated blood pressure reductions of −6.9 mmHg (SBP) and −3.2 mmHg (DBP; p < 0.01) [ 83 , 84 ]. Additionally, a study conducted in children reported an improvement in omega-3 fatty acid status with the Nordic diet that was associated with improvements in school performance ( p < 0.05) [ 85 ]. A systematic review parsing the individual components of the Nordic diet found that evidence supported the protective effects of eating whole grains on type 2 diabetes and cardiovascular disease risk, but that there was insufficient evidence for other foods in the Nordic diet [ 86 ].

3.5. Traditional Asian Diets

Although there is substantial evidence supporting the Mediterranean and other European-based diets, traditional regional dietary patterns from other parts of the world that follow similar principles have less–well-established links to positive health outcomes. A full description of the breadth of regional diets and the associated evidence bases is beyond the scope of this publication, but we consider some Asian-based diets to be particularly relevant to this discussion.

The traditional Korean diet is composed of rice and other whole grains, fermented food, indigenous land and sea vegetables, proteins primarily from legumes and fish as opposed to red meat, medicinal herbs (e.g., garlic, green onions, ginger), and sesame and perilla oils [ 87 ]. Meals typically consist of multiple small-portion dishes are often derived from seasonal food sources and are home-cooked. Unlike the Western diet, the traditional Korean diet does not include many fried foods [ 87 ]. Epidemiologic data suggest a reduced risk of metabolic syndrome (odds ratio [OR]: 0.77; 95% CI: 0.60–0.99), obesity (OR: 0.72; 95% CI: 0.55–0.95), hypertension (OR: 0.74; 95% CI: 0.57–0.98), and hypertriglyceridemia (OR: 0.76; 95% CI: 0.59–0.99) among individuals who follow traditional Korean dietary patterns [ 88 ]. These findings are consistent with a controlled clinical trial that explored the effects of a traditional Korean diet compared with a control diet (“eat as usual”) on cardiovascular risk factors in patients with diabetes and hypertension. In that study, adherence to a traditional Korean diet favorably influenced body composition (body weight, −2.3 kg; body mass index [BMI], −0.83 kg/m 2 ; body fat, −2.2%; p < 0.01), heart rate (−7.1 bpm; p = 0.002), and glycemic control (HbA1c, −0.72%; p = 0.003) [ 89 ].

The traditional Chinese diet features rice or noodles, soups, vegetables, steamed breads or dumplings, fruits and vegetables, soy, seafood, and meat [ 90 , 91 ]. Although higher in carbohydrates and lower in fat compared with a Western diet, the traditional Chinese diet does not appear to promote weight gain in healthy, normal-weight Chinese, suggesting that carbohydrate restriction may not be a universally applicable intervention to combat obesity and cardiometabolic risk [ 92 ]. One 6-week controlled trial demonstrated that 52% of non-Chinese individuals with overweight or obesity who adhered to a traditional Chinese diet had a reduction in BMI while preserving lean body mass compared with 28% of those who followed a Western diet at the 1-year follow-up assessment [ 93 ]. In another trial, BMI decreased by 0.37 kg/m 2 and lean mass by 0.21 kg among subjects who adhered to a traditional Chinese diet for 6 weeks, whereas those who followed a Western diet had 0.26 kg/m 2 and 0.49 kg reductions in BMI and lean body mass, respectively [ 94 ]. Notably, both of these studies restricted caloric intake to 1,200 Kcal for the test and control diet groups.

Similar to the Korean diet, the traditional Japanese diet (known as Washoku) is characterized by small portions of multiple components, primarily including rice, fish (often eaten raw), soups, and pickles [ 95 ]. Fermented soybean paste (dashi) serves as the base of many of the soups that are central to the traditional Japanese diet; other ingredients include seaweed, fruits and vegetables, and mushrooms. The use of chopsticks, alternating between dishes of small portion size throughout a meal, and the base flavor of Japanese food (umami) enhance satiety and help to prevent overeating. Adherence to a traditional Japanese dietary pattern has been associated with favorable effects on blood pressure among apparently healthy Japanese adults [ 96 ]. This is consistent with data from the 2012 Japan National Health and Nutrition Survey demonstrating that adherence to a traditional Japanese diet compared with a Western diet or a meat- and fat-based dietary pattern was associated with a lower prevalence of hypertension in men [ 97 ]. However, in the same study, a traditional Japanese diet was associated with higher DBP in women, as well as higher waist circumference and BMI in men. Further study is needed to elucidate the health impacts of traditional Japanese and other Asian dietary patterns.

4. Additional Factors

While the evidence reviewed here suggests that the described dietary patterns positively influence measures of health and disease risk and outcome because they encourage the intake of foods that individually have beneficial effects and the avoidance of unhealthy options, additional factors combine to create a lifestyle that promotes health. For example, healthy diets include adequate hydration, typically in the form of water or tea/herbal infusions [ 7 , 49 , 51 , 52 ]. In addition to the dietary components, a healthy lifestyle is one that incorporates regular exercise, socialization, and adequate sleep [ 7 , 52 ], and minimizes elements that have a negative effect on health such as tobacco use, excessive alcohol consumption, physical inactivity, large amounts of screen time, and stress.

The importance of non-dietary factors is reflected in their inclusion in modern food pyramids. Built on a base of positive lifestyle factors, the lower tiers indicate daily consumption of adequate hydration and nutrient-rich, plant-based foods, with animal-derived products (meat, fish, and dairy) and sweets comprising higher tiers of the pyramid (i.e., less frequently or infrequently consumed items).

Whereas the goal may be to achieve nutrient requirements through food and water intake alone, there are situations in which food-derived nutrient intake might be inadequate due to increased need, selective eating, or food insecurity/limited access to more nutritious foods [ 98 , 99 , 100 ]. Therefore, for some individuals, dietary supplements may be required, particularly at certain life phases. For example, later in life, the recommended intake of calcium increases to sustain bone mineral density [ 101 ]; hence, supplementation with calcium may be necessary to meet recommended intake levels in older adults. Before initiating supplementation, dietary intake levels should be considered to avoid exceeding the upper tolerability limits and causing adverse events.

There are a number of other traditional regional diets that likely have similar benefits to those that we describe here. However, we made the decision to narrow our focus to those diets with evidence from randomized, controlled trials demonstrating their health benefits. For example, the African Heritage Diet focuses on traditional ingredients that may be beneficial to African American populations who experience disproportionately higher risks for chronic diseases related to their diets [ 102 ]. Future research is warranted to evaluate the impact of the African Heritage Diet and other regional dietary patterns on health.

5. Conclusions

Healthy diets, arising either by tradition or design, share many common features and generally align with the WHO Global Action Plan for the Prevention and Control of Noncommunicable Diseases. In comparison with a Western diet, these healthier alternatives are higher in plant-based foods, including fresh fruits and vegetables, whole grains, legumes, seeds, and nuts and lower in animal-based foods, particularly fatty and processed meats. Evidence from epidemiologic studies and clinical trials indicates that these types of dietary patterns reduce risks of NCDs ranging from cardiovascular disease to cancer. Further endeavors are needed to integrate these healthy dietary and lifestyle choices into daily living in communities throughout the world and to make healthy eating accessible, achievable, and sustainable.

Healthy Diet Essay

Consuming a healthy diet throughout a person’s life helps prevent malnutrition in all its forms, as well as a range of diet-related non-communicable diseases and conditions. But the increased consumption of processed food, rapid urbanisation and changing lifestyles have led to a shift in dietary patterns. People now consume fast food and do not eat enough fibre-rich fruits, vegetables and whole grains. So, to help students understand the importance of a healthy diet, we have provided a “Healthy Diet” essay.

Students can also go through the list of CBSE Essays on different topics. It will help them to improve their writing skills and also increase their scores on the English exam. Moreover, they can participate in different essay writing competitions which are conducted at the school level.

500+ Words Healthy Diet Essay

A healthy diet consists of simple, natural and/or well-cooked foods which promote health and protect us from diseases. It keeps our organ systems functioning well. The diet that we consume is decided by our socio-cultural norms, lifestyle patterns and the type of activities we are engaged in. A healthy diet includes nutrition, nutrients, food groups, a balanced diet and special dietary requirements.

Balanced Diet

A diet that contains all the essential nutrients like proteins, carbohydrates, fats, minerals and vitamins in the proportion required for the normal growth and development of the body is called a balanced diet. The important components of a balanced diet are cereals, pulses, milk, fruits and vegetables, fats and oil. A balanced diet constitutes a healthy diet. Thus, we all should try to follow a balanced diet.

Role of Nutrients

Nutrients that we obtain through food have vital effects on physical growth and development. It also helps in maintaining normal body function, physical activity and health. Nutritious food is thus needed to sustain life and activity. A healthy diet must provide all essential nutrients in the required amounts. Requirements for essential nutrients vary with age, gender, physiological status and physical activity. Dietary intakes lower or higher than the body requirements can lead to undernutrition or overnutrition, respectively.

Eating too little food during certain significant periods of life such as infancy, childhood, adolescence, pregnancy and lactation and eating too much at any age can lead to harmful consequences. An adequate diet, providing all nutrients, is needed throughout our lives. Eating a variety of foods from each food group is crucial for supplying the individual with all the essential nutrients that the body needs, including carbohydrates, proteins, fats, vitamins, minerals and water.

Special Dietary Requirements

The amount of food or nutrients required by a person in a day depends upon the need for energy. These needs are directly related to age and physical activity. During the rapid growth years, i.e. 12–22 years for boys and 12–18 years for girls, there is a gradual increase in daily food requirements. But as we grow old, our daily need for energy decreases. The amount of energy required by people engaged in low, moderate or high levels of physical activity differs. A sports person always needs to consume more calories than a non-sports person. Similarly, the dietary needs of a woman during pregnancy and lactation are higher.

Before we eat, we should think about what goes on our plate, cup, or bowl. Foods like vegetables, fruits, whole grains, low-fat dairy products, and lean protein foods should be part of our diet. These contain the nutrients that we need to maintain a heart-healthy eating plan. Eating a healthy diet will keep our body fit, healthy and free from all kinds of diseases. With a healthy body and mind, we can enjoy our life and can achieve whatever we want in our life.

Students must have found the “Healthy Diet” essay useful for improving their essay writing skills. They can get the study material and the latest updates on CBSE/ICSE/State Board/Competitive Exams at BYJU’S.

Junk food vs Healthy Food

If we look at the scenario today, we see how the fast-food market is increasing at a rapid rate. With the onset of food delivery apps and more, people now like having junk food more. In addition, junk food is also tastier and easier to prepare.

However, just to satisfy our taste buds we are risking our health. You may feel more satisfied after having junk food but that is just the feeling of fullness and nothing else. Consumption of junk food leads to poor concentration. Moreover, you may also get digestive problems as junk food does not have fiber which helps indigestion.

Similarly, irregularity of blood sugar levels happens because of junk food. It is so because it contains fewer carbohydrates and protein . Also, junk food increases levels of cholesterol and triglyceride.

On the other hand, healthy food contains a plethora of nutrients. It not only keeps your body healthy but also your mind and soul. It increases our brain’s functionality. Plus, it enhances our immunity system . Intake of whole foods with minimum or no processing is the finest for one’s health.

In short, we must recognize that though junk food may seem more tempting and appealing, it comes with a great cost. A cost which is very hard to pay. Therefore, we all must have healthy foods and strive for a longer and healthier life.

Healthy food is not just about what you eat – it’s also about how you eat it. For example, eating fresh, whole foods that are prepared at home with love and care is generally considered to be healthier than eating processed, pre-packaged foods that are high in salt, sugar, and unhealthy fats. Additionally, eating in moderation and avoiding excessive portion sizes is key to maintaining a healthy diet.

There are many reasons to eat healthy food, but the most obvious one is that it can help to prevent a wide range of health problems. Eating a diet rich in fruits, vegetables, and other healthy foods can help to lower your risk of heart disease, stroke, obesity, and other chronic conditions.

500 Words Essay On Healthy Food

Healthy food is an essential aspect of a healthy lifestyle. It is not only crucial for maintaining physical health, but it can also have a significant impact on our mental and emotional well-being. Eating a balanced diet that includes a variety of fruits, vegetables, whole grains, and lean proteins can help us feel energised, focused, and happy. But for many people, eating healthy can be a challenge. In a world where fast food and processed snacks are readily available and often more convenient than cooking a meal from scratch, it can be tempting to choose unhealthy options. And with busy schedules and hectic lives, it can be difficult to find the time and energy to plan and prepare healthy meals.

However, the benefits of eating healthy far outweigh the challenges. Not only can it help us maintain a healthy weight and reduce our risk of chronic diseases like heart disease, diabetes, and cancer, but it can also improve our mood, energy levels, and overall quality of life.

My Experience

As I sat down at my desk with a bag of chips and a soda for lunch again, I realised that I had been making unhealthy food choices all week. I had been so busy with work and other obligations that I hadn't taken the time to plan and prepare healthy meals. I decided then and there to make a change. I started by making a grocery list of nutritious, whole foods and meal planning for the week ahead. I also made a commitment to myself to cook at home more often instead of relying on takeout or fast food. It wasn't easy at first, but over time, I started to notice a difference in my energy levels and overall mood. I felt better physically and mentally, and I was able to maintain a healthy weight. Making healthy food choices became a priority for me, and I am now reaping the numerous benefits of a nutritious diet.

One of the key components of a healthy diet is variety. Eating a diverse range of fruits, vegetables, whole grains, and lean proteins can provide our bodies with the nutrients, vitamins, and minerals we need to function at our best. It's important to try to incorporate a rainbow of colours into our diets, as each colour group represents different nutrients and health benefits. For example, orange and yellow fruits and vegetables are rich in vitamin C and beta-carotene, which can support healthy skin and eyesight. Green leafy vegetables like spinach and kale are packed with antioxidants and can help support a healthy immune system. And blue and purple fruits and vegetables, like blueberries and eggplants, are high in flavonoids and can help support brain health and cognitive function.

In addition to eating a variety of fruits and vegetables, it's also important to include whole grains in our diets. Whole grains, like quinoa, brown rice, and oatmeal, are a great source of fibre, which can help keep us feeling full and satisfied. They can also help regulate our blood sugar levels, which can keep our energy levels steady and prevent unhealthy cravings.

Importance of Healthy Diet essay

A healthy diet is one that helps to maintain or improve overall health. We should consume a balanced diet consisting of essential nutrition. A healthy and balanced diet reduces stress levels and promotes healthy life without any suffering.

Importance of Healthy Diet essay (350+ Words)

People consume junk foods and unhealthy items solely for taste, neglecting the importance of nourishing their bodies. A healthy and balanced diet reduces stress and promotes a suffering-free life, highlighting its utmost significance.

Daily Test - Attempt Now

A healthy diet maintains or improves overall health through essential nutrition: liquids, proteins, fatty acids, vitamins, minerals, and calories. To maintain a healthy body, we should consume fresh fruits, salad, green leafy vegetables, milk, eggs, yogurt, etc., on time.

Green vegetables and fruits provide minerals like iron, calcium, sodium, potassium , iodine, copper, etc. Fish oil, butter, carrot, papaya, etc., contain Vitamin A, while green leafy vegetables, wheat grain, etc., contain Vitamin B.

Vitamin C is found in green chili, green vegetables, amla, lemon, and citric fruits. Vitamin D is present in fish oil, butter, and sun rays. Vitamins E and K are necessary for our health, and milk is a well-balanced diet on its own.

We should only eat fresh, well-washed, and well-cooked food that is free from dust and flies. Harmful are fried foods and foods with excess fat, spices, and chilies. Eating on the roadside should be avoided. The last meal should be taken two or three hours before going to bed. Our stomach needs a good time gap between two meals for proper digestion.

In addition to proper nutrition, a healthy body requires daily physical activities, adequate rest and sleep, cleanliness, a healthy environment, fresh air, and water, as well as personal hygiene. Furthermore, it is important to drink a sufficient amount of water, at least 7-8 glasses. This not only balances blood pressure but also supplies essential nutrients rapidly to the body. An individual who is fit and healthy develops a higher resistance to infections and diseases.

While wealth holds some significance, it is not as important as health. Spending a large amount of money on junk food in five-star hotels or other entertainment sources, such as watching films for a day, yields no advantages except for self-satisfaction.

Physical and mental well-being enables an individual to be socially and financially healthy. A healthy person is more active, lively, and energetic, working with utmost efficiency. Conversely, a wealthy but unhealthy person easily succumbs to fatigue, ultimately losing the true wealth of life, namely, health.

From the crispy crunch of fresh veggies to the creamy indulgence of decadent desserts, we all have different food preferences. Our palates develop uniquely, shaped by genetics, culture and personal experiences.

Food preferences play a significant role in shaping our dietary habits. Highly palatable foods rich in sugars, fats and salts often appeal to people’s tastebuds and provide immediate satisfaction. However, these foods are typically high in calories and low in essential nutrients, leading to weight gain, and a higher risk of physical and mental health conditions.

Now we have discovered that the food you choose to eat isn’t just linked to your physical and mental health, but also to your cognitive function, brain structure and genetics.

A widespread preference for fast food is likely contributing to an increase in obesity worldwide. According to the World Health Organization (WHO), in 2022 one in eight people worldwide were obese. This rate has doubled since 1990.

Obesity isn’t just linked with an increased risk of diseases including type 2 diabetes and cardiovascular disease, but also with a 30-70% higher risk of mental health disorders .

Benefits of a healthy, balanced diet

Our new collaborative study from Fudan University in China and the University of Cambridge in the UK, published in Nature Mental Health , used a large sample of 181,990 participants from the UK Biobank to examine how food choices are associated with cognitive function, mental health, metabolism, brain imaging and genetics.

We examined the consumption of vegetables, fruit, fish, meat, cheese, cereal, red wine, spirits and bread. We found that 57% of participants had food preferences for a healthy balanced diet. This included a balanced mix of all the foods we examined, with no excessive amounts in any category.

We further showed that those with a healthy balanced diet had better brain health, cognitive function and mental health than others. We compared the balanced diet to three other diet groups – low-carb (18%), vegetarian (6%) and high protein/low fibre (19%).

We found that people who ate a more balanced diet had better fluid intelligence (the ability to solve new problems), processing speed, memory and executive functions (a set of mental skills that include flexible thinking and self-control) than the other diets. This also corresponded to better brain health – with higher grey matter volumes (the outermost layer of the brain) and better structured neurons (brain cells), which are key markers of brain health.

Perhaps surprisingly, the vegetarian diet did not fare as well as a balanced diet. One reason for this may be that many vegetarians don’t get enough protein. Two healthy, balanced diets for the brain are the Mediterranean and Mind (Mediterranean intervention for neurodegenerative delay) diets.

These promote fish (especially those oily fish), dark leafy vegetables and fresh fruits, grains, nuts, seeds, as well as some meat, such as chicken. But these diets also limit red meat, fats and sugars.

In fact, research has shown that the Mediterranean diet can alter our brains and cognition. One study showed that people showed improved cognition after only 10 weeks on this diet.

Another study showed that following the Mediterranean diet was associated with lower levels of a harmful peptide known as beta-amyloid in the brain. Beta-amyloid, together with tau protein, are measures of the brain damage that occurs in Alzheimer’s disease.

Previous studies have also shown that Japanese diets , including rice, fish and shellfish, miso, pickles and fruits, protect against brain shrinkage.

We also discovered that there were some genes that may be contributing to the association between dietary patterns and brain health, cognitive function and mental health. This may mean that our genes partly determine what we like to eat, which in turn determines our brain function.

However, our food choice priorities are also affected by a number of factors, including price, allergies, convenience and what our friends and family eat.

Some people opt for going on diets, which may lead to weight loss, but involve cutting out entire food groups that are important for the brain. While there’s some evidence that ketogenic diets (low carb), for example, have beneficial affects on the immune system and mental health , it does seem that balanced diets, such as the Mediterranean diet, is best for overall brain health and cognition.

Ways forward

It is clear that adopting a healthy balanced diet and doing exercise can be good for our brains. But for many people, this is easier said than done, especially if their current food preferences are for very sweet or high fat foods.

However, food preferences aren’t destiny. For example, if you reduce your sugar and fat intake slowly and maintain it at a very low level over a number of months, you will actually begin to prefer that type of food.

Establishing healthy food preferences and an active lifestyle early in childhood is vital. Other important techniques are to eat slowly, pay attention to what you eat and enjoy it, rather than finishing a sandwich on the go or while looking at your mobile screen.

It takes time for your brain to register that you are full. For example, it has been shown that consumers generally eat more when watching television , listening to music, or in the presence of others, because the distraction decreases our reliance on internal satiety signals.

Social support from friends has also been shown to encourage adherence to healthy eating habits , as has cognitive behavioural therapy . Distraction is another excellent technique – literally anything you like to do (that isn’t eating) could help.

One interesting survey study found that how you set your priorities affects your food choices. If you are keen to remain healthy and to have a physically fit appearance, you will choose healthy foods .

We live in tough economic times. Socioeconomic status shouldn’t limit dietary choices, though this seems to currently be the case. Clearly, governments have an important duty to prioritise affordable healthy eating options. This will help many of us choose a healthy diet for either health reasons, reduced food prices, or both.

Now that we know that the food we eat can actually affect our brains and how well we perform cognitively, having a healthy balanced diet is more important than ever.

500 Words Essay on Importance of Healthy Eating Habits

Introduction.

The importance of healthy eating habits cannot be overstated, particularly in a world where fast food and processed meals have become the norm. Healthy eating habits are not just about maintaining an ideal weight or avoiding obesity; they are also about ensuring optimal physical and mental health, and enhancing overall quality of life.

The Role of Nutrition in Human Health

Nutrition plays a pivotal role in human health. A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats provides the essential nutrients that our bodies need to function properly. These nutrients are vital for maintaining energy levels, supporting brain function, aiding in cellular repair, strengthening the immune system, and preventing chronic diseases.

The Impact of Unhealthy Eating Habits

On the contrary, unhealthy eating habits such as consuming high amounts of processed foods, sugary snacks, and fatty meals can lead to numerous health issues. These include obesity, heart disease, diabetes, and certain types of cancer. Moreover, poor nutrition can also affect mental health, contributing to conditions like depression and anxiety.

Healthy Eating and Cognitive Function

Healthy eating habits are also crucial for cognitive function. Nutrients like Omega-3 fatty acids, antioxidants, and B vitamins, which are found in foods like fish, nuts, fruits, and vegetables, are essential for brain health. They enhance memory, improve mood, and protect against cognitive decline.

Importance of Healthy Eating Habits in College Students

For college students, maintaining healthy eating habits is particularly important. The rigors of academic life, coupled with the challenges of living independently, can lead to poor nutrition. This can result in decreased academic performance, poor concentration, and increased stress levels. By adopting healthy eating habits, students can improve their academic performance, boost their mood, and better manage stress.

In conclusion, healthy eating habits are a cornerstone of good health and well-being. They play a critical role in maintaining physical health, supporting mental well-being, and enhancing cognitive function. For college students, they are particularly important for academic success and stress management. Therefore, it is essential to prioritize healthy eating and make it a part of our daily routine. By doing so, we can improve our health, enhance our quality of life, and set ourselves up for long-term success.

Pumpkin seed protein has 1 advantage over other plant-based options, dietitians say

Full of all kinds of heart- and gut-healthy nutrients , it's easy to forget that pumpkin seeds are also a major source of plant-based protein .

Pumpkin seed protein has been popping up in products like protein powders, bars and shakes more and more over the last few years, says Natalie Rizzo, registered dietitian and TODAY.com nutrition editor.

It's often marketed towards people who are avoiding whey , soy or nut-based protein products because it's "an allergy friendly protein," she says.

There aren't as many peer-reviewed studies about pumpkin seed protein benefits as there are for options like whey or soy protein shakes, powders, and bars, Rizzo says, because it's a newer addition to the market. But we know pumpkin seeds are a healthy option for many reasons.

"Because it's coming from pumpkin seeds, (pumpkin seed protein products are) rich in protein, minerals and fiber," Theresa Gentile, a registered dietitian in New York City and a spokesperson for the Academy of Nutrition and Dietetics, tells TODAY.com.

"It's a good plant-based choice for someone who doesn't want to have whey protein or casein protein in something like a protein bar ," she adds.

If you're thinking of trying out pumpkin seed protein, here's what dietitians want you to know.

Pumpkin seed protein benefits

Essential amino acids.

All protein is made up of amino acids. There are nine amino acids that our bodies can't make on their own, which means we need to get them from food.

Pumpkin seed protein contains all nine of those essential amino acids, the experts say. But because a few of those amino acids are present in smaller amounts, it's not technically considered a complete protein, which is generally the case for all plant-based proteins.

Pumpkin seeds have 8.5 grams of protein per ounce serving , compared to 10 to 20 grams per serving in pumpkin seed protein powder.

"It has lots of good quality protein, but it's pretty low in two of those amino acids: methionine and tryptophan," Gentile says.

As long as you're eating a variety of foods throughout the day, that's not necessarily a problem, Rizzo says. "Even if you are completely vegan, if you eat seeds with legumes, you'll get enough of those essential amino acids." 

Gut-healthy fiber

Regular pumpkin seeds contain a good amount of fiber , especially if eaten with the shells, Gentile says.

With the shells, an ounce of roasted pumpkin seeds provides about 5 grams of fiber compared to about 2 grams for shelled pumpkin seeds, according to the American Heart Association . But they may lose some of that fiber when they're ground down into a protein powder.

All protein powders are "heavily processed" in one way or another, Rizzo says. "So you're going to strip out some of the fiber for sure." Depending on the brand of protein powder you're using, you may see 1 gram or more of fiber per serving in the product.

Healthy fats

Nuts and seeds, including pumpkin seeds, are a great source of healthy omega-3 fatty acids , Gentile says.

Omega-3s support the health of your heart and blood vessels as well as your immune system and hormone systems, the National Institutes of Health explain. They also provide some anti-inflammatory benefits as well, Gentile says.

Magnesium and other nutrients

Pumpkin seeds boast large amounts of several other beneficial nutrients, including antioxidants, iron , phosphorous, zinc and magnesium.

The magnesium is a particular "highlight" of pumpkin seed protein because it provides more than you'd get from other plant-based protein sources, Rizzo says. "Pumpkin seeds are naturally rich in magnesium, which is a nutrient that a lot of people don't get enough of," she explains.

Magnesium is beneficial for heart and bone health as well as blood sugar management.

Pumpkin seeds in protein powder blends

You won't always see pumpkin seed protein on its own. Sometimes companies mix it with other plant-based protein sources — like pea protein , chickpea protein or nut butters — to complement the nutrients it provides.

"The benefit of mixing it with other (plant-based protein) powders is you're getting a little bit of good stuff from everything," Gentile says.

That's also a way for companies to "get all the amino acids in there in good amounts," Rizzo says. So if you're concerned about missing out on any of those, a supplement that contains a blend of plant-based protein sources may be a good option.

List of fruits with the most health benefits: These 8 are expert recommended

O nly about 12% of surveyed Americans meet their daily fruit intake , the Centers for Disease Control and Prevention found in 2019. That number is even lower among low-income adults.

Eating fruits and vegetables is an important part of a healthy diet, but for many who live in areas of food insecurity access may be a challenge. The U.S. Department of Agriculture found 44.2 million Americans lived in food-insecure households in 2022. 

Meanwhile, an estimated 30-40% of the food supply in the U.S. goes to waste.

Healthiest fruits to include in your diet

If you live in an area with access to fresh produce, any choice of fruit is a healthy one, says registered dietitian Danielle Crumble Smith . However, each fruit has a unique nutritional profile and benefits. Here are some of the must-haves for your diet:

• Wild blueberries: These berries pack in the fiber to keep you fuller for longer. They also rank among the fruits and vegetables with the highest antioxidant content. Antioxidants prevent or delay cell damage. Studies show wild blueberries have cognitive and cardiovascular benefits as well as cancer-fighting compounds, Crumble Smith says.
• Apples: Apples are rich in antioxidants, especially darker-colored varieties like Red Delicious. They have vitamin C and fiber, found mostly in the skin, and pectin , a fiber that acts as a prebiotic to aid colon function and digestion . Apples also contain quercetin, a flavonoid with antioxidant properties that studies show may reduce cardiovascular disease risk and protect against allergies because it acts as a natural antihistamine .
• Oranges: These bright citrus fruits contain about 92% of your daily vitamin C requirement. They're a good source of folate , a B vitamin that’s important during pregnancy but can also play a role in preventing cardiovascular disease, infertility, stroke, dementia, colon cancer and Alzheimer’s disease.
• Grapefruit: Grapefruits are a good source of vitamin C , which the body uses to form blood vessels, cartilage, muscle and collagen in the bones. Vitamin C also acts as an antioxidant and helps the body absorb and store iron. Grapefruits also contain vitamin A, which helps support eye health and cell growth.
• Strawberries: Strawberries are high in vitamin C, which helps support the immune system. They contain manganese, folate and potassium .
• Pineapple: Pineapple packs in vitamins C, A, K, phosphorus, zinc and calcium. It's rich in manganese and contains bromelain , an extract found in the fruit and stem of pineapples that has anti-inflammatory properties.
• Papaya: Papayas contain vitamins C, A, E, folate, fiber and a high level of antioxidants, including lycopene .
• Plums: These fruits contain antioxidants like anthocyanins and quercetin, which may reduce the risk of heart disease . They’re also high in fiber, which can help regulate bowel movements. Plums are lower in sugar and have a low glycemic index, making them ideal for anyone with diabetes , insulin resistance or blood sugar dysregulation, Crumble Smith says.
• Kiwi: Kiwis contain high amounts of vitamins C, E and fiber. You'll also get an enzyme called actinidin, which helps digestion , and lutein and zeaxanthin, two antioxidants that benefit eye health .

Is fruit good for you?

Aside from making a tasty snack, fruit is beneficial because it contains vitamins, minerals, fiber, water and other essential nutrients, Crumble Smith previously told USA TODAY. 

Fruit can help combat the afternoon slump better than reaching for another cup of coffee . And because natural sugar is a healthy source of energy, pairing fruit with protein will give you a similar boost.

Crumble Smith does recommend caution for people with diabetes , insulin resistance or blood sugar issues. In that case, be mindful of portion size or try to pair your afternoon raspberries with a protein, like yogurt or cheese.

Fruit smoothies are an easy and accessible way to get your daily fruit content. Crumble Smith recommends making them at home rather than grabbing one from a smoothie bar or a pre-packaged drink from the store. If you’re going for bottled juice, read the nutritional label thoroughly to check for added sugar content. 

"All the concentrated fruit tends to be really high in sugar and don’t have any protein to help stabilize blood sugar levels," she told USA TODAY in 2023.

How much fruit should you eat per day?

The daily recommended fruit serving depends on several factors, including age, height, sex, weight and physical activity. Generally, the USDA says adults should consume around 2 cups of fruit per day. 

Here are some examples of what counts as a “cup” of fruit:

• 1 small apple
• 1 large banana
• 22 seedless grapes
• 1 large peach
• 3 medium plums
• 1 slice of watermelon

How can I plan what to eat or drink when I have diabetes?

How can physical activity help manage my diabetes, what can i do to reach or maintain a healthy weight, should i quit smoking, how can i take care of my mental health, clinical trials for healthy living with diabetes.

Healthy living is a way to manage diabetes . To have a healthy lifestyle, take steps now to plan healthy meals and snacks, do physical activities, get enough sleep, and quit smoking or using tobacco products.

Healthy living may help keep your body’s blood pressure , cholesterol , and blood glucose level, also called blood sugar level, in the range your primary health care professional recommends. Your primary health care professional may be a doctor, a physician assistant, or a nurse practitioner. Healthy living may also help prevent or delay health problems  from diabetes that can affect your heart, kidneys, eyes, brain, and other parts of your body.

Making lifestyle changes can be hard, but starting with small changes and building from there may benefit your health. You may want to get help from family, loved ones, friends, and other trusted people in your community. You can also get information from your health care professionals.

What you choose to eat, how much you eat, and when you eat are parts of a meal plan. Having healthy foods and drinks can help keep your blood glucose, blood pressure, and cholesterol levels in the ranges your health care professional recommends. If you have overweight or obesity, a healthy meal plan—along with regular physical activity, getting enough sleep, and other healthy behaviors—may help you reach and maintain a healthy weight. In some cases, health care professionals may also recommend diabetes medicines that may help you lose weight, or weight-loss surgery, also called metabolic and bariatric surgery.

Choose healthy foods and drinks

There is no right or wrong way to choose healthy foods and drinks that may help manage your diabetes. Healthy meal plans for people who have diabetes may include

• dairy or plant-based dairy products
• nonstarchy vegetables
• protein foods
• whole grains

Try to choose foods that include nutrients such as vitamins, calcium , fiber , and healthy fats . Also try to choose drinks with little or no added sugar , such as tap or bottled water, low-fat or non-fat milk, and unsweetened tea, coffee, or sparkling water.

Try to plan meals and snacks that have fewer

• foods high in saturated fat
• foods high in sodium, a mineral found in salt
• sugary foods , such as cookies and cakes, and sweet drinks, such as soda, juice, flavored coffee, and sports drinks

Your body turns carbohydrates , or carbs, from food into glucose, which can raise your blood glucose level. Some fruits, beans, and starchy vegetables—such as potatoes and corn—have more carbs than other foods. Keep carbs in mind when planning your meals.

You should also limit how much alcohol you drink. If you take insulin  or certain diabetes medicines , drinking alcohol can make your blood glucose level drop too low, which is called hypoglycemia . If you do drink alcohol, be sure to eat food when you drink and remember to check your blood glucose level after drinking. Talk with your health care team about your alcohol-drinking habits.

Find the best times to eat or drink

Talk with your health care professional or health care team about when you should eat or drink. The best time to have meals and snacks may depend on

• what medicines you take for diabetes
• what your level of physical activity or your work schedule is
• whether you have other health conditions or diseases

Ask your health care team if you should eat before, during, or after physical activity. Some diabetes medicines, such as sulfonylureas  or insulin, may make your blood glucose level drop too low during exercise or if you skip or delay a meal.

Plan how much to eat or drink

You may worry that having diabetes means giving up foods and drinks you enjoy. The good news is you can still have your favorite foods and drinks, but you might need to have them in smaller portions  or enjoy them less often.

For people who have diabetes, carb counting and the plate method are two common ways to plan how much to eat or drink. Talk with your health care professional or health care team to find a method that works for you.

Carb counting

Carbohydrate counting , or carb counting, means planning and keeping track of the amount of carbs you eat and drink in each meal or snack. Not all people with diabetes need to count carbs. However, if you take insulin, counting carbs can help you know how much insulin to take.

Plate method

The plate method helps you control portion sizes  without counting and measuring. This method divides a 9-inch plate into the following three sections to help you choose the types and amounts of foods to eat for each meal.

• Nonstarchy vegetables—such as leafy greens, peppers, carrots, or green beans—should make up half of your plate.
• Carb foods that are high in fiber—such as brown rice, whole grains, beans, or fruits—should make up one-quarter of your plate.
• Protein foods—such as lean meats, fish, dairy, or tofu or other soy products—should make up one quarter of your plate.

If you are not taking insulin, you may not need to count carbs when using the plate method.

Work with your health care team to create a meal plan that works for you. You may want to have a diabetes educator  or a registered dietitian  on your team. A registered dietitian can provide medical nutrition therapy , which includes counseling to help you create and follow a meal plan. Your health care team may be able to recommend other resources, such as a healthy lifestyle coach, to help you with making changes. Ask your health care team or your insurance company if your benefits include medical nutrition therapy or other diabetes care resources.

Talk with your health care professional before taking dietary supplements

There is no clear proof that specific foods, herbs, spices, or dietary supplements —such as vitamins or minerals—can help manage diabetes. Your health care professional may ask you to take vitamins or minerals if you can’t get enough from foods. Talk with your health care professional before you take any supplements, because some may cause side effects or affect how well your diabetes medicines work.

Research shows that regular physical activity helps people manage their diabetes and stay healthy. Benefits of physical activity may include

• lower blood glucose, blood pressure, and cholesterol levels
• better heart health
• healthier weight
• better mood and sleep
• better balance and memory

Talk with your health care professional before starting a new physical activity or changing how much physical activity you do. They may suggest types of activities based on your ability, schedule, meal plan, interests, and diabetes medicines. Your health care professional may also tell you the best times of day to be active or what to do if your blood glucose level goes out of the range recommended for you.

Do different types of physical activity

People with diabetes can be active, even if they take insulin or use technology such as insulin pumps .

Try to do different kinds of activities . While being more active may have more health benefits, any physical activity is better than none. Start slowly with activities you enjoy. You may be able to change your level of effort and try other activities over time. Having a friend or family member join you may help you stick to your routine.

The physical activities you do may need to be different if you are age 65 or older , are pregnant , or have a disability or health condition . Physical activities may also need to be different for children and teens . Ask your health care professional or health care team about activities that are safe for you.

Aerobic activities

Aerobic activities make you breathe harder and make your heart beat faster. You can try walking, dancing, wheelchair rolling, or swimming. Most adults should try to get at least 150 minutes of moderate-intensity physical activity each week. Aim to do 30 minutes a day on most days of the week. You don’t have to do all 30 minutes at one time. You can break up physical activity into small amounts during your day and still get the benefit. 1

Strength training or resistance training

Strength training or resistance training may make your muscles and bones stronger. You can try lifting weights or doing other exercises such as wall pushups or arm raises. Try to do this kind of training two times a week. 1

Balance and stretching activities

Balance and stretching activities may help you move better and have stronger muscles and bones. You may want to try standing on one leg or stretching your legs when sitting on the floor. Try to do these kinds of activities two or three times a week. 1

Some activities that need balance may be unsafe for people with nerve damage or vision problems caused by diabetes. Ask your health care professional or health care team about activities that are safe for you.

Stay safe during physical activity

Staying safe during physical activity is important. Here are some tips to keep in mind.

Drink liquids

Drinking liquids helps prevent dehydration , or the loss of too much water in your body. Drinking water is a way to stay hydrated. Sports drinks often have a lot of sugar and calories , and you don’t need them for most moderate physical activities.

Avoid low blood glucose

Check your blood glucose level before, during, and right after physical activity. Physical activity often lowers the level of glucose in your blood. Low blood glucose levels may last for hours or days after physical activity. You are most likely to have low blood glucose if you take insulin or some other diabetes medicines, such as sulfonylureas.

Ask your health care professional if you should take less insulin or eat carbs before, during, or after physical activity. Low blood glucose can be a serious medical emergency that must be treated right away. Take steps to protect yourself. You can learn how to treat low blood glucose , let other people know what to do if you need help, and use a medical alert bracelet.

Avoid high blood glucose and ketoacidosis

Taking less insulin before physical activity may help prevent low blood glucose, but it may also make you more likely to have high blood glucose. If your body does not have enough insulin, it can’t use glucose as a source of energy and will use fat instead. When your body uses fat for energy, your body makes chemicals called ketones .

High levels of ketones in your blood can lead to a condition called diabetic ketoacidosis (DKA) . DKA is a medical emergency that should be treated right away. DKA is most common in people with type 1 diabetes . Occasionally, DKA may affect people with type 2 diabetes  who have lost their ability to produce insulin. Ask your health care professional how much insulin you should take before physical activity, whether you need to test your urine for ketones, and what level of ketones is dangerous for you.

Take care of your feet

People with diabetes may have problems with their feet because high blood glucose levels can damage blood vessels and nerves. To help prevent foot problems, wear comfortable and supportive shoes and take care of your feet  before, during, and after physical activity.

If you have diabetes, managing your weight  may bring you several health benefits. Ask your health care professional or health care team if you are at a healthy weight  or if you should try to lose weight.

If you are an adult with overweight or obesity, work with your health care team to create a weight-loss plan. Losing 5% to 7% of your current weight may help you prevent or improve some health problems  and manage your blood glucose, cholesterol, and blood pressure levels. 2 If you are worried about your child’s weight  and they have diabetes, talk with their health care professional before your child starts a new weight-loss plan.

You may be able to reach and maintain a healthy weight by

• following a healthy meal plan
• consuming fewer calories
• being physically active
• getting 7 to 8 hours of sleep each night 3

If you have type 2 diabetes, your health care professional may recommend diabetes medicines that may help you lose weight.

Online tools such as the Body Weight Planner  may help you create eating and physical activity plans. You may want to talk with your health care professional about other options for managing your weight, including joining a weight-loss program  that can provide helpful information, support, and behavioral or lifestyle counseling. These options may have a cost, so make sure to check the details of the programs.

Your health care professional may recommend weight-loss surgery  if you aren’t able to reach a healthy weight with meal planning, physical activity, and taking diabetes medicines that help with weight loss.

If you are pregnant , trying to lose weight may not be healthy. However, you should ask your health care professional whether it makes sense to monitor or limit your weight gain during pregnancy.

Both diabetes and smoking —including using tobacco products and e-cigarettes—cause your blood vessels to narrow. Both diabetes and smoking increase your risk of having a heart attack or stroke , nerve damage , kidney disease , eye disease , or amputation . Secondhand smoke can also affect the health of your family or others who live with you.

If you smoke or use other tobacco products, stop. Ask for help . You don’t have to do it alone.

Feeling stressed, sad, or angry can be common for people with diabetes. Managing diabetes or learning to cope with new information about your health can be hard. People with chronic illnesses such as diabetes may develop anxiety or other mental health conditions .

Learn healthy ways to lower your stress , and ask for help from your health care team or a mental health professional. While it may be uncomfortable to talk about your feelings, finding a health care professional whom you trust and want to talk with may help you

• lower your feelings of stress, depression, or anxiety
• manage problems sleeping or remembering things
• see how diabetes affects your family, school, work, or financial situation

Ask your health care team for mental health resources for people with diabetes.

Sleeping too much or too little may raise your blood glucose levels. Your sleep habits may also affect your mental health and vice versa. People with diabetes and overweight or obesity can also have other health conditions that affect sleep, such as sleep apnea , which can raise your blood pressure and risk of heart disease.

NIDDK conducts and supports clinical trials in many diseases and conditions, including diabetes. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.

What are clinical trials for healthy living with diabetes?

Clinical trials—and other types of clinical studies —are part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help health care professionals and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of healthy living for people with diabetes, such as

• how changing when you eat may affect body weight and metabolism
• how less access to healthy foods may affect diabetes management, other health problems, and risk of dying
• whether low-carbohydrate meal plans can help lower blood glucose levels
• which diabetes medicines are more likely to help people lose weight

5 superfood fruits and berries with mental and physical health benefits to add to your diet

Super fruits can boost brain function, improve heart health and act as an anti-inflammatory.

By Margaret Darby

Several fruits and berries are considered superfoods for their physical and mental health benefits such as improved heart health, boosted brain function, lowered symptoms of depression and anti-inflammatory impacts.

“On average, people who eat more berries seem to live a little bit longer,” Eric Rimm , professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health, told The Washington Post . Rimm suggests incorporating fruits and berries to a healthy diet every day to reap benefits.

Here are five superfood fruits and berries with mental and physical health benefits.

1. Blueberries can improve brain function

Blueberries boast benefit for both mental and physical health. Research shows eating blueberries can improve brain function , lower symptoms of depression and aid in maintaining a healthy heart .

“Much of the power of blueberries lies in their colors. The deep-blue hue comes from anthocyanin, a phytochemical whose abilities may help protect the body from heart disease and Type 2 diabetes, offering cancer-fighting benefits, promote gut health and reduce inflammation,” reports the Mayo Clinic .

“A one-cup serving of blueberries contains 25% of the recommended daily value for vitamin C and 4 grams of dietary fiber, but only 80 calories.”

Adding just a handful of blueberries to your daily diet could improve brain function, found a study from King’s College London . Researchers asked participants to consume wild blueberry powder for a duration of 12 weeks. Individuals who consumed the blueberry powder experienced improved memory and increased accuracy on attention tasks.

Regularly eating blueberries can also help relieve anxiety and ease feelings of depression because they are rich in antioxidants, per WebMD . A study from the British Journal of Nutrition found that adolescents who took daily wild blueberry supplements reported lower symptoms of depression.

2. Avocados are heart-healthy

Despite common misconceptions, avocados are actually single-seeded berries, per Healthline . They are an excellent source of healthy fat, fiber, potassium, magnesium and vitamins B, C, E and K.

“Avocados contain several nutrients including carotenoids, monounsaturated fats, potassium, and fiber that have been associated with a reduced risk of chronic diseases, especially when included as part of a balanced nutritious diet,” per Harvard Health .

Frequently eating avocados is heart-healthy, according to a 30-year study published in the Journal of the American Heart Association. Researchers found that those who regularly ate avocados experienced a significantly reduced risk of developing cardiovascular disease compared to individuals who rarely ate avocados.

The study also noted that individuals who ate avocados at least twice per week experienced a 21% lower risk of coronary heart disease, compared to those who rarely or never eat avocados.

3. Cherries have anti-inflammatory properties

Professional athletes report drinking tart cherry juice to aid in reduced inflammation and muscle pain, per The Washington Post . Studies show that tart cherries and tart cherry juice have a similar impact to anti-inflammatory drugs.

“The anti-inflammatory and antioxidant properties of cherries work like nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen for reducing or preventing pain,” registered dietitian Carly Sedlacek told Cleveland Clinic .

A study from the Journal of the International Society of Sports Nutrition found that runners who consumed cherry juice throughout the week before a race experienced significantly less muscle pain.

Tart and sweet cherries may also improve sleep. A review from the journal Nutrients found that cherries’ high levels of melatonin, serotonin and tryptophan aided in increasing quality and quantity of sleep.

4. Acai berries protect cognitive function

Acai is a nutrient-dense berry loaded with antioxidants. Research shows these unique berries improve cholesterol , protect cognitive function , reduce cancer risk and support liver health .

Acai berries are one of the richest natural sources of anthocyanins, the antioxidant that give the berries their deep purple color.

“Anthocyanins (provide) anti-inflammatory effects in the body, (and) may help reduce the risk of chronic diseases such as heart disease, diabetes, and cancer,” registered dietitian Kristen Nicolai told Everyday Health . “They also protect against free radical damage known as oxidative stress, which can lead to chronic and acute conditions.”

Eating acai berries could protect the brain as it ages. One animal study reported that acai might help improve memory while aging. Another study , published in the journal Molecular Neurobiology, found that acai berries might have an anti-inflammatory, neuroprotective impact on Parkinson’s disease. Researchers found that acai supplements were able to mitigate Parkinson’s disease through reducing the loss of dopamine.

5. Citrus fruits can improve colds

Oranges, grapefruits, lemons, limes, clementines and pomelos are all citrus fruits. These zesty fruits offer a great source of fiber, may protect against cancer , boost heart health , improve cognitive function in older adults and aid in maintaining a healthy heart .

Citrus fruits are also one of the best dietary sources of vitamin C.

“Citrus fruits, including oranges, lemons, limes, grapefruits and clementines, are an excellent source of vitamin C. And vitamin C supports your immune system, which plays a role in maintaining healthy skin, bones and blood vessels,” reports the Mayo Clinic . “Citrus fruits contain soluble and insoluble fiber, both of which provide great benefits.”

A study from the American Journal of Lifestyle Medicine linked the consumption of vitamin C found in citrus fruits with decreased duration and severity of the common cold. Researchers found that those who took vitamin C supplements while suffering from a common cold experienced shortened illness by 8% in adults and 14% in children.
