Moreover, nowadays the trend of junk food is here to stay. People are not taking a balanced diet rather eating all sorts of harmful foods. It is more important than ever to tell people about the importance of a balanced diet. You cannot merely exercise and expect your body to stay fit. A balanced diet is crucial for that.

Most importantly, it is called a ‘balanced’ diet because it requires all the foods to be eaten in a balanced manner. For instance, if you intake large amounts of carbohydrates and a little amount of protein, then that will not be called a balanced diet, even if you are eating the right foods. The balance needs to be maintained for that.

How to Have a Balanced Diet?

One can always adopt a healthy lifestyle by starting to consume a balanced diet. Firstly, one must definitely increase the amount of liquid to consume in a day. Fluids are very important for the human body to function healthily. As almost 80% of our body is filled with water, we need it for good metabolism. Thus, start with drinking at least two to three liters of water every day. Moreover, try cutting down on the consumption of tea, coffee, alcohol, and other such addictive liquids.

Furthermore, one must always eat fresh vegetables and fruits. As fresh fruits and vegetables are great sources of fiber and vitamins, we must consume them for good body growth. Try to avoid eating deep-fried or overcooked food as it loses all its nutrients. The balanced diet must have the five essential elements, i.e. bitter, sour, sweet, pungent and salty. Also, the emphasis is on fresh fruits because the processed or packed ones do not have nutrients.

Most importantly, always chew your food patiently. Do not just swallow it after chewing for four-five times. This way your food won’t get digested properly. Savor the food slowly and steadily. Next, do not eat in excess. You must know when to draw the line and stop when you don’t have the appetite. Therefore, we see how a balanced diet will keep you healthy and fit. It will improve the quality of your life and keep all the illnesses away.

Components of a balanced diet.

• Carbohydrates are the primary source of energy for the body. They are found in foods such as grains, fruits, vegetables, and legumes. Complex carbohydrates, such as those in whole grains, are particularly beneficial as they release energy slowly and help maintain stable blood sugar levels. Proteins are essential for growth, repair, and maintenance of body tissues. Sources of protein include meat, fish, eggs, dairy products, legumes, and nuts. Proteins are made up of amino acids, some of which are essential and must be obtained through diet. Fats are vital for several bodily functions, including hormone production, nutrient absorption, and cell membrane integrity. Healthy fats, such as those found in avocados, nuts, seeds, and oily fish, should be included in the diet, while trans fats and saturated fats should be limited. Vitamins and minerals are required in smaller amounts but are indispensable for various metabolic processes. For example, vitamin C is important for immune function, while calcium is crucial for bone health. A diet rich in fruits, vegetables, and whole grains typically provides a sufficient supply of these micronutrients. Benefits of a Balanced Diet Consuming a balanced diet offers numerous benefits, including the maintenance of a healthy weight, prevention of chronic diseases, and enhancement of mental health. Healthy Weight Management A balanced diet helps in maintaining a healthy weight by providing the right proportion of nutrients without excessive calories. It encourages the consumption of nutrient-dense foods over calorie-dense, nutrient-poor options. This is crucial for preventing obesity, which is a risk factor for various health conditions, including heart disease, diabetes, and certain cancers. Prevention of Chronic Diseases A balanced diet can prevent numerous chronic diseases. For instance, a diet rich in fruits, vegetables, and whole grains has been associated with a reduced risk of cardiovascular diseases. Adequate intake of dietary fiber helps in maintaining healthy cholesterol levels and promoting heart health. Moreover, antioxidants present in various fruits and vegetables can help in reducing inflammation and oxidative stress, thereby lowering the risk of chronic illnesses. Mental Well-being Nutrition also plays a significant role in mental health. A balanced diet that includes essential fatty acids, vitamins, and minerals is linked with improved mood and cognitive function. Omega-3 fatty acids, found in fish and flaxseeds, are known to support brain health. Conversely, deficiencies in certain nutrients, such as vitamin B12 and iron, can lead to cognitive impairments and mood disorders. Consequences of an Imbalanced Diet An imbalanced diet, characterized by the overconsumption of certain nutrients and the deficiency of others, can lead to various health issues. Malnutrition Malnutrition can manifest in several forms, including undernutrition and overnutrition. Undernutrition, resulting from a lack of essential nutrients, can lead to stunted growth, weakened immunity, and increased susceptibility to infections. On the other hand, overnutrition, often due to excessive intake of calories, fats, and sugars, can result in obesity and related health problems. Increased Risk of Diseases An imbalanced diet can increase the risk of several diseases. For example, high intake of saturated fats and sugars can lead to the development of type 2 diabetes, heart disease, and other metabolic disorders. Additionally, insufficient intake of fruits and vegetables can result in deficiencies of essential vitamins and minerals, weakening the immune system and increasing vulnerability to illnesses. Mental Health Issues Poor dietary habits can adversely affect mental health. Diets high in processed foods, sugars, and unhealthy fats have been linked to an increased risk of depression and anxiety. Conversely, a lack of essential nutrients can impair brain function and contribute to cognitive decline and mental health disorders. Conclusion In conclusion, a balanced diet is fundamental to achieving and maintaining optimal health. It provides essential nutrients required for bodily functions, helps in maintaining a healthy weight, prevents chronic diseases, and supports mental well-being. Conversely, an imbalanced diet can lead to malnutrition, increased disease risk, and mental health issues. Therefore, it is imperative to adopt a balanced diet that includes a variety of nutrient-rich foods to promote overall health and well-being.

A Healthy Lifestyle and a Well Balanced Diet Essay

• To find inspiration for your paper and overcome writer’s block
• As a source of information (ensure proper referencing)
• As a template for you assignment

A healthy lifestyle and a well-balanced diet are both essential for the well-being of modern society. Nevertheless, obesity, malnutrition, and eating disorders are becoming increasingly alarming problems in today’s world. Moreover, an unhealthy diet can accompany and exacerbate conditions such as stress, depression, and overwork. By applying for the Dietetic Internship at Florida International University, I am looking forward to integrating my knowledge of balanced nutrition into counseling people to gain healthier eating habits.

Coming from Middle Eastern origins, gatherings mostly revolved around food. Whenever there was a celebration food had to be present. Although my dad’s side of the family suffered from obesity and diabetes, they did not have the tools to understand how nutrition could improve regarding chronic diseases. Seeing some of my family members pass away from these diseases made me want to provide a better and well-rounded understanding of nutrition. Facilitating people is a goal that I would like to achieve while educating people that do not have enough knowledge or any background in nutrition. Having food is a necessity but in some countries, food and water are not available. I aim to achieve availability and accessibility concerning nutrition education in third-world countries.

Throughout my life, I have been interested in a healthy lifestyle. I have often shared what I learned with my cousins and other family members. The information that I knew was inaccessible to those without such education, and it made me think about how much society influences what is right and wrong to eat. With my own family as an example, I can assert that both extreme low-calorie diets and overeating do not improve a person’s mental and physical condition. Currently, my primary goal is to help people get better in their nutritional patterns and come into harmony with themselves, letting them know that food is not bad to eat, but that it fuels a healthier life. Therefore, my strongest motivation and aim to become a registered dietitian is to educate people about the incredible opportunities for proper nutrition and a healthy lifestyle.

I believe that a dietitian can genuinely make a difference in changing the situation with a growing number of diagnosed overweight and improper eating habits for the better. My personal and academic experience demonstrate enthusiasm in this internship. My initial goal was to translate personal interests into a professional skill, which I hope to achieve in my career. Over the past academic years, I have participated in various nutrition-related activities to increase and expand my knowledge and different areas of the topic such as community nutrition and clinical nutrition. Attending courses and workshops on dietetics deepened my knowledge and understanding of a professional dietician’s role in society. In addition, I actively performed group and individual assignments and demonstrated my motivation and knowledge of the topics. My high inspiration and the ability to work individually and in a team is a traits that can be well-implemented in this sphere of work. While my work allows me to self-motivate and manage, I can also adapt to the leadership or work styles of my colleagues.

Organizing and playing a leading role in many extracurricular events and meetings dedicated to poor eating habits and lack of nutritional knowledge in society, in both academic and clinical settings, have allowed me to achieve good results by expanding my knowledge and doing extra research. I have developed methods and behaviors that assist in my management of responsibilities when it comes to nutrition-related activities. In my working experience with patients and athletes, I have demonstrated advertency and empathy to be my main advantages for this position. Since people with eating disorders often require compassion, additional attention, and involvement in the treatment process, I believe mindfulness and a caring attitude are vital in dealing with patients. Additionally, I find that continued work and interaction with a patient is essential even after initial treatment, to observe favorable results.

Although academic skills are valuable to me, I believe that practical applications of knowledge are an integral part of the training. I also realize that to be entirely successful in my profession, I critically need to gain more practical experience in a clinical setting. I have strengths in leadership, individual work, and technical knowledge, but I understand that I need further improvement in my practical experience, teamwork, and contentious learning of dietetics. By applying for FIU Dietetic Internship, I am looking forward to gaining new expertise, employing it in practice, and developing communication skills for further advancement in my chosen profession. As a future registered dietitian, I hope to serve people and promote the most appropriate health and lifestyle choices. I believe that it is vital to recommend diet and nutrition methods, depending on individual preferences, requirements, and health indications. As I move forward in my profession, I will develop individualized approaches to patient health and be considerate and respectful concerning their potential conditions. I hope to use this internship to perform according to professional instructions, receive and implement criticism, gain experience, and continue working with others in the dietetics field. In this regard, FIU Dietetic Internship is also an excellent opportunity to develop my professional goals.

250 Words Essay on Balanced Diet

Introduction.

A balanced diet is not just a meal plan, but a lifestyle choice that promotes optimal health and well-being. It is a diet that includes an appropriate proportion of nutrients such as proteins, vitamins, minerals, carbohydrates, and fats, derived from a variety of food sources.

The human body requires a diverse range of nutrients for its complex functions and processes. A balanced diet supplies these nutrients in the right quantities, thereby ensuring the body’s physiological functions are maintained. It boosts the immune system, supports growth and development, and reduces the risk of chronic diseases such as obesity, diabetes, and cardiovascular diseases.

A balanced diet comprises of five main food groups: fruits and vegetables, proteins, dairy, grains, and fats. Fruits and vegetables provide essential vitamins, minerals, and fiber. Proteins, found in meat, fish, and legumes, are vital for growth and repair. Dairy products supply calcium for strong bones and teeth. Grains, particularly whole grains, are a great source of energy and provide fiber, iron, and B-vitamins. Fats, though often vilified, are necessary in moderate amounts for energy and absorption of fat-soluble vitamins.

In conclusion, a balanced diet is a cornerstone of good health. It requires mindful choices and variety in food consumption. It’s not about strict limitations, but rather about improving overall health, feeling good, having more energy, and boosting mood. It is an investment in one’s health and well-being, and its benefits extend beyond the individual to society at large.

500 Words Essay on Balanced Diet

Introduction to balanced diet.

A balanced diet is a cornerstone of health. It is the key to our body’s proper functioning and well-being. It refers to the intake of appropriate types and adequate amounts of foods and drinks to supply nutrition and energy for the maintenance of body cells, tissues, and organs, and to support normal growth and development.

The significance of a balanced diet cannot be overstated. It provides the necessary nutrients required for the body to function effectively. Nutrients such as proteins, carbohydrates, fats, vitamins, and minerals are critical for various body functions. For instance, proteins are essential for growth and repair, carbohydrates provide energy, fats act as energy reserves, and vitamins and minerals are crucial for various metabolic processes.

A balanced diet also plays a pivotal role in maintaining optimal body weight, enabling overall physical well-being and boosting mental health. It can prevent various chronic diseases such as obesity, heart disease, diabetes, and cancer.

A balanced diet consists of a variety of foods from different food groups. These include:

1. Fruits and Vegetables: They are rich in vitamins, minerals, and fiber. They boost immunity and help in digestion.

3. Carbohydrates: Foods like bread, rice, and potatoes provide energy.

5. Dairy: Milk and dairy products are an excellent source of calcium for bone health.

The Concept of Moderation and Variety

In the context of a balanced diet, the principles of moderation and variety are crucial. Moderation refers to controlling portion sizes and not overindulging in particular foods to prevent excess calorie intake and associated health issues. Variety, on the other hand, pertains to consuming a wide array of foods across and within each food group. This ensures the intake of a broad spectrum of different nutrients.

In conclusion, a balanced diet is integral to good health and well-being. It provides the body with essential nutrients required for optimal functioning. Remember, it’s not about short-term dietary changes but rather about a long-term lifestyle modification. Eating a variety of foods, in the right proportions, and consuming the right amount of food and drink to achieve and maintain a healthy body weight are the key components of a balanced diet. A balanced diet, coupled with regular exercise, can lead to a better quality of life and contribute to a longer and healthier future.

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.

Unhealthy diets and malnutrition

Home / why ncds / risk factors & prevention / unhealthy diets and malnutrition.

• Unhealthy diets and the resulting malnutrition are major drivers of noncommunicable diseases (NCDs) around the world.
• Malnutrition includes undernutrition, overweight and obesity, and other diet-related NCDs like type 2 diabetes , cardiovascular disease (heart diseases) and stroke, and some cancers .
• What people eat has changed dramatically over the last few decades. This has been driven by shifts towards calorific and fatty foods, eating out, and an increase in food portion sizes, combined with a lower intake of fruit, vegetables, and high-fibre foods.
• Healthy diets are unaffordable for the poor in every region of the world and people are increasingly exposed to ultra-processed, unhealthy foods and diets that lead to poorer health.
• Policy solutions to tackle poor diets are considered low-cost. The World Health Organization (WHO) ‘Best Buys’ include interventions to reduce salt and sugar intake, such as front-of-pack labelling, fiscal tools and educational initiatives, and measures to eliminate industrial trans-fats.

Malnutrition occurs when the body is not receiving enough of the right nutrients to function properly. This can present as under-nutrition, such as wasting and stunting, but also as overweight, obesity, and diet-related NCDs such as cardiovascular disease and stroke, type 2 diabetes and some cancers.

Many countries now experience a ‘double burden’ of malnutrition. This is where under-nutrition occurs alongside over-nutrition, where unhealthy diets are contributing to unhealthy weight gain and diet-related poor health.[ 1] These unhealthy diets consist of food and drinks with high levels of energy (calories), salt, sugar, and fats, notably industrial trans fats (also known as trans-fatty acids, TFAs or iTFA).

Around the world, 1.9 billion adults are overweight or obese, while 462 million are underweight.[ 2 ] In a study that looked at global deaths from 1990 to 2017, it was found that one in every five deaths were the result of poor nutrition. [3 ]

What is a healthy diet?

According to the WHO, healthy diets are rich in fibre, fruit, vegetables, lentils, beans, nuts, and wholegrains. These diets are balanced, diverse and meet a person’s macronutrient (protein, fat, carbohydrate and fibre) and micronutrient (minerals and vitamins) needs depending on their stage of life.

Generally, healthy diets contain:

• Fat intake of less than 30% of total energy. These should be mainly unsaturated fats, with less from saturated fats. Trans fats should not be consumed.
• Sugar intake of less than 10% of total energy, but preferably less than 5%.
• Salt intake of less than 5g per day.
• Fruit and vegetables intake at least 400g per day.[ 4 ]

Food systems and changes in the way we eat

A person’s ability to maintain a healthy diet is often not within their control – it is influenced by the food environment where they live, early life nutrition, income, and accessibility.[ 5 ] The ‘food system’ refers to all processes of getting food from production to our plates. The food system is often dictated by location, climate, culture, consumer behaviour, industry practices and the regulatory environment, among other factors.

Rise in ultra-processed foods and drinks

Over several decades, dietary habits have changed dramatically around the world. Globalisation and urbanisation have paved the way for a rise in convenience food and drinks products, junk food, and eating out, with fewer people growing or making their food from scratch.

These cheap and ready-to-consume food and drinks products are often ‘ultra-processed’ and high in calories, fats, salt and sugar and low in nutrients. They are produced to be hyper-palatable and attractive to the consumer, like burgers, crisps, biscuits, confectionery, cereal bars, and sugary drinks.[ 6 ]

Ultra-processed foods and drinks typically have a long shelf life, making them appealing for businesses like supermarkets, rather than highly perishable fresh goods. Intensive marketing by the industry – especially to children – has also increased the consumption of these types of goods. Increasingly, these products are displacing fresh, nutritious, and minimally processed goods, shifting population diets and food systems.

Vulnerable populations and poorer people in all parts of the world struggle to access and maintain a healthy diet. It is in these settings where ultra-processed food and beverage products are most prevalent. An estimated three billion people cannot afford healthier food choices with poverty negatively impacting the nutritional quality of food.[ 7 ]

Which diseases are linked to unhealthy diets and malnutrition?

Unhealthy diets and resulting malnutrition are linked to several noncommunicable diseases, including:

• Overweight and obesity – also associated with elevated blood pressure, high cholesterol, diabetes, cardiovascular disease and stroke, cancers and resistance to the action of insulin.
• Cardiovascular disease (heart disease) and stroke.
• Type 2 diabetes and hypertension (high blood pressure).
• Some cancers – including oesophageal cancer; tracheal, bronchus and lung cancer; lip and oral cavity cancer; nasopharynx cancer; colon and rectum cancer.[ 8 ]

These diseases are driven by common dietary risk factors, including:

• High salt intake – a leading dietary risk factor for death and illness worldwide. High salt consumption increases blood pressure, which increases the risk of cardiovascular disease and stroke, chronic kidney disease and some cancers.
• High sugar intake – excess sugars can contribute to tooth decay and weight gain, leading to overweight and obesity, as well as higher blood pressure, cardiovascular disease and stroke, and some cancers.[ 9 ]
• High trans fats intake – linked to cardiovascular disease and stroke.
• Low fruit and veg intake – linked to several cancers, cardiovascular disease and stroke.
• Low intake of fibres, grains, nuts, seeds, micronutrients – linked to diabetes, cardiovascular disease and stroke, and some cancers.[ 10 ]

Childhood malnutrition

Early life nutrition has important impacts on the likelihood of disease and poor health later in life. But childhood malnutrition remains one of the biggest challenges in public health today.

In 2020, an estimated 22% and 7% of children under five were affected by stunting and wasting, respectively, and 7% were overweight. Most of these children live in lower- and middle-income countries. Asia and Africa account for nine out of ten of all children with stunting and wasting and more than seven out of ten children who are affected by overweight. [11 ]

Breastfeeding is one of the most effective ways to ensure the development of a healthy immune system in children, protecting against childhood malnutrition and poor health throughout the life course. But aggressive marketing of formula and baby foods seeds doubt in mothers, compromising breastfeeding and other healthy feeding practices in early childhood.[ 12 ] Policies that protect and promote breastfeeding, including the regulation of breast milk substitute industry, are critical public health interventions.

What can be done to tackle unhealthy diets and malnutrition?

Strategies to tackle unhealthy diets and malnutrition – leading to overweight, obesity and many noncommunicable diseases – should be part of a comprehensive package of policies that aim to improve the food system.

One of the most straightforward nutrition policies is the elimination of industrially-produced trans fats, or trans fatty acids (iTFA), from the global food supply. If all countries removed this harmful compound that causes heart disease, 17 million lives could be saved by 2040. An additional estimated 2.5 million deaths could be prevented each year if global salt consumption were reduced to the recommended level. [13 ]

Implementing strong nutrition policies will not only accelerate progress towards global NCD targets – but is essential to build healthier and more resilient populations that are better prepared to deal with future health emergencies, such as COVID-19.

What’s more, many nutrition measures are considered cost-effective by the WHO and included in their ‘Best Buys’ of recommended interventions to reduce the burden of NCDs around the world. [14 ]

Specific measures include:

• Reformulation of food and drinks products to contain less salt, sugar and fats – with the goal of eliminating all trans-fats.
• Limiting marketing and promotion of unhealthy food and drink products – especially to children and adolescents, including online and in places where they congregate.
• Front-of-pack nutrition labels which clearly warn of the high content of ingredients including fats, sugar, and salt. Front-of-pack labelling systems have now been implemented in more than 30 countries (where governments have led and supported their development), and systems are under development in many other countries.
• Taxes on sugar-sweetened beverages to reduce sugar consumption.
• Subsidies on fruit and vegetables to increase intake of healthier food choices.
• Increasing incentives for producers and retailers to grow, use and sell fresh fruit and vegetables.
• Protecting and promoting breastfeeding.
• Promoting awareness of better nutrition through mass media campaigns.
• Nutrition education and counselling in preschools, schools, workplaces and health centres.

Case study: Bold action in Mexico leads the way

*NCD Alliance acknowledges support from Resolve to Save Lives in the production of this video.

Mexico has among the highest prevalence of diet-related NCDs and obesity in the world. Around three-quarters of people in Mexico live with overweight or obesity, including one-third of all children. Diet-related conditions such as type 2 diabetes and hypertension are rising in prevalence.

Mexico has been taking big steps to improve health by reducing the high prevalence of largely preventable chronic diseases like obesity, type 2 diabetes and some cancers. But the government and health civil society have faced fierce challenges from the big businesses behind the products that are making people sick. As the pandemic took hold in 2020, and world leaders debated the crisis, the Mexican Minister of Health drew attention to how neglecting to prevent NCDs had made the world’s people more vulnerable to the novel coronavirus.

Health authorities urged Mexicans to transition to healthier diets and habits to reduce the COVID-19 burden. Yet the junk food industry continues to operate despite the government’s efforts, using the pandemic food crisis to put foods high in sugar, salt and fat into children’s hands as much as possible, with no regard to the harmful impact of these foods.

So, while the Mexican federal government persists with its effective soda tax, they have also strengthened their position with strong front-of-pack labelling and trans-fats elimination to create healthier environments for the people of Mexico.

“The tax on sugar-sweetened beverages in Mexico is projected to prevent 239,900 instances of obesity, of which almost 40% would be among children.”

But impatient for Federal regulations to come into force and be implemented, Congress in the region of Oaxaca went a step further, voting to ban the sale of junk food to children altogether and placing the control of purchasing into the hands of parents. The Ley Anti Charra (Anti-Junk Food Law), applies to stores, schools and vending machines. Enforcement is complex, but there is strong public support to defend the health of the most vulnerable population: children. One thing is for sure, with rates of obesity and diet-related NCDs rising in most countries, more must take bigger, braver steps like Mexico to fix food systems and protect children from the foods and drinks that are making us all sick.

What Are the Effects of an Unhealthy Diet?

When you come home after a long day of work, it can be tempting to order some food or grab takeout and relax. After all, who wants to go through all the effort of cooking and cleaning up when you're tired? Consuming fast food occasionally isn't harmful, but eating too much can result in an unhealthy diet. Unhealthy diets can be harmful and have long-term effects on your health.

An unhealthy diet can lead to health issues such as malnutrition, poor digestion, inflammation, unwanted weight gain and obesity. It can also increase your risk of chronic diseases, such as diabetes and heart disease, and impact your mental health.

Video of the Day

What Is a Healthy Diet?

You've probably heard the saying a million times — "eat a balanced diet." But what exactly is a balanced diet ? According to the Office of Health Promotion and Disease Prevention , the American dietary guidelines state that most people should consume:

• ‌ Grains, including bread, pasta and rice. ‌ Nine to 11 servings per day are recommended.
• ‌ Vegetables. ‌ Four to five servings each day are recommended.
• ‌ Fruit. ‌ Three to four servings each day are recommended.
• ‌ Protein, including beans, fish, meat and nuts. ‌ Two to three servings per day are recommended.

Consumption of all of these constitutes a balanced, healthy diet. Together, these foods give you all of the recommended vitamins and minerals you need each day. This includes vitamins A, C, E and K as well as B-complex vitamins. It also includes quite a few minerals, including calcium, copper, iodine, iron, magnesium, manganese, phosphorus, potassium, selenium and zinc. There is no single food that can give you all of these nutrients.

What Is an Unhealthy Diet?

Now that we know what a balanced diet is, what is an unhealthy diet ? There are actually many types of unhealthy diets. Traditionally, fast food products are linked to unhealthy diets, as one in three Americans eats fast food each day . Rich in carbohydrates and high-fat content, frequent consumption of fast food products like fries, fried chicken and pizza can definitely contribute to an unhealthy diet. However, fast foods aren't the only cause of unhealthy diets.

Unhealthy diets can involve eating only one type of food. Recently, an extreme diet called the carnivore diet received attention from the media because the diet involves eating only meat. A person who is consuming only meat products is likely not getting the daily vitamins and minerals he or she needs. This can be easily rectified by adding fruits, vegetables and grains to the diet. A diet involving one single type of food of any kind is likely going to be bad for you in the long run.

Another example of an unhealthy diet is a diet involving excessive consumption of a certain product or nutrient. An example of this is a diet high in sodium . Someone who chooses to eat bacon, cold cuts and other salt-preserved products with frequency will likely be consuming too much sodium. This can result in a variety of health issues , like increased blood pressure and risk of cardiovascular disease. While a little extra salt here and there may not seem like a big deal, 9 out of 10 Americans eat too much sodium. In general, consuming too much of anything can result in an unhealthy diet with negative health benefits.

The Dangers of Unhealthy Eating

The effects of unhealthy eating can sometimes result in obvious physical changes, such as acne, bloating and weight gain. Certain unhealthy diets, like those linked to too much fast food, can result in obesity and related diseases. According to the Centers for Disease Control , having overweight or obesity can increase the risk for diabetes, heart disease, osteoarthritis, stroke and many other conditions. Obvious physical changes don't occur to everyone. However, just because the effects of unhealthy eating aren't obvious doesn't mean they aren't happening.

It's possible to consume an unhealthy diet for a long time and suddenly experience its effects. According to a Civil Eats interview with Hilal Elver , the United Nations Special Rapporteur on the Right to Food, fast foods are a leading cause of malnutrition. Malnutrition is one of the biggest dangers of unhealthy eating and can lead to diseases like scurvy. Caused by a deficiency in vitamin C , scurvy can happen to people who prefer carbohydrate-rich diets, avoiding fresh fruit and vegetables. An unhealthy diet won't immediately cause scurvy. You'd have to be vitamin C-deficient for about three months before getting this disease.

Nutrient deficiencies can also have long-term effects. According to the book Modern Nutrition in Health and Disease , written by Department of Nutritional Sciences researchers at Pennsylvania State University, certain vitamins and minerals can reduce your chance of diseases that appear later in life, like osteoporosis. Calcium and vitamin D contribute to bone health and can reduce the risk of osteoporosis as you age.

The effects of your eating habits are more important than you may realize. Every food that you eat has the potential to change your gut microbiome. According to a 2014 study in Nature , trillions of microorganisms reside in your digestive system. The microbes that live in these communities are influenced by the foods you eat every day. Unhealthy diets can cause an imbalance in these microbial communities and allow too many of a certain type to live in your gastrointestinal tract. This can negatively impact digestion, metabolism and cause diseases like inflammatory bowel disease. Because your gut is directly linked to your brain through a cranial nerve, your diet can even impact your mental health.

The effects of eating habits may be more influential than you think. It's important to be aware of both the short-term and long-term effects of unhealthy eating, and to always try to consume a balanced diet.

Long Essay on Balanced Diet 500 words in English

Balanced Diet Essay is usually given to classes 7, 8, 9, and 10.

A balanced diet is a diet that contains all essential food groups. There are five primary nutrients that our body requires for proper functioning. The carbohydrates are the energy-giving food that contains starch and sugar; proteins are bodybuilding foods, fats are energy-giving, vitamins and minerals are foods that make us resistant to diseases. All these food groups are vital for our good health.

Apart from the primary five nutrients, there is also roughage and water. Roughage is the fiber portion of the food we eat, and water is crucial for regulating our body processes. A balanced diet contains all these nutrients in appropriate quantities. It is essential to understand what kind of food gives us nutrients. Bread, potatoes, sugar, rice, and chapattis are rich in carbohydrates. We must consume this kind of food as they are our primary source of energy. Any vegetable that grows under the ground, for example, carrots, sweet potato, radishes are rich in carbohydrates. Children and adolescents must consume carbohydrates as they need a lot of energy.

Meat, fish, pulses, lentil, eggs, milk, and every kind of milk product like cottage cheese and paneer are rich in proteins. Proteins are our main source of energy. Proteins are essential for people of every age group. Anybody who wants to eat less fat for their meals must compensate for it by eating more proteins. Proteins are necessary for adolescents since they help in muscle development.

Oil, sugar, cream, cheese, red meat, ghee, butter, etc. are all rich in fat. Fat gives us more energy. Children should consume an adequate amount of fat as they need it for their growth. Fats, when consumed in large quantities, resulting in excess deposition of adipose tissue and leads to weight gain. However, fats are an essential component of our diet, and we must take them adequately.

Fruits and leafy vegetables are rich in vitamins and minerals. Vitamins and minerals build our body defenses against diseases and viral infections. Deficiency of vitamins can cause many conditions ranging from night blindness to scurvy. It can also make our gums bleed and lead to the formation of painful scabs in our mouth. Most importantly, deficiency of vitamins and minerals causes us more exposed to illnesses. Roughage is vital for smooth bowel movements. Fibers are essential for digestion and bowel formation. Water is indispensable to facilitate every bodily function starting from metabolism to assimilation. Water is vital for survival, and we cannot live without it.

A balanced diet is rich in all these nutrients. It must contain the required food groups in appropriate quantities. An athlete or somebody who engages in heavy physical labour must consume large amounts of protein. Protein gives them the energy to work hard. A person who is mainly involved in desk work must consume less fat as he has almost no physical exercise. Thus, he must consume food that his body can break down quickly. All in all, a balanced diet ensures our good health and is vital for leaving a healthy life.

Below we have provided a Balanced Diet Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 and 10.

When diet is wrong, medicine is of no use. When diet is correct, medicine is of no need. – Ancient Ayurvedic Proverb

From the very start, we are taught to eat a balanced diet. Our mothers make sure that we eat healthy and stay strong. What exactly is a balanced diet? A balanced diet or a healthy diet contains an equal amount of proportions of food from all the food groups. It is a balance of fats, carbohydrates, proteins, sugar, vitamins and minerals. An average adult requires about 3200 calories a day to keep the body system performing and functioning adequately. How to get this calorie intake, is up to the individual.

Overeating of something can be as harmful to the body, as having too little of it. It is a general misconception that malnutrition happens because of a lack of food. But the truth is that malnutrition is the result of a lack of the right amount of different foods. Eating food in wrong amounts and incorrect proportions can be detrimental to the health of a person and can cause severe ailments and diseases.  This type of thoughtless diet is known as an unhealthy diet or an imbalanced diet.

Importance of a Balanced Diet

A balanced diet promotes good physical as well as mental health. Not only are we in good shape physically, but our mind also seems to be in a safe and right space. We are able to focus more, and our retention power increases. Our ability to do work in a proper manner rises significantly, and we are distracted less. Having a balanced diet also helps in proper growth of the body. It aids in cell division and helps them multiply. Consumption of a balanced diet is also necessary to surge the ability of the body to fight germs and illnesses.

It increases and builds our immunity system, thus making our body and its structures stronger while fighting them. Foods such as walnuts and avocados can help keep the mind away from mental diseases such as depression and dementia. It also helps in controlling your body weight. The intake of healthy and nutrient-dense foods like vegetables, eggs, salads and oats stays in the body for long periods and then breaks down into your bloodstream. It doesn’t let your brain trigger towards the consumption of sugary snacks or processed foods which only increase your fat component and are not even utilized in providing you with energy.

Components of a Balanced Diet

Following are the key elements that constitute a balanced diet:

• Proteins : Found abundantly in eggs, chicken, fish, sprouts, dairy products, etc., proteins act as healing agents of the body. They repair the wear and tear of the muscles caused by our daily activities and also help in growth and building muscles.
• Vitamins and Minerals : These can be found in plenty of fruits and vegetables. They help the body in becoming more immune and in resisting and fighting grave diseases. A lack of vitamins and minerals in the body can lead to an individual suffering from conditions like goitre, anaemia, etc.
• Fats : Present richly in food products such as butter, oil, ghee, etc., fats help you keep your body warm and supply the necessary energy required. Too much fat can be harmful as it may lead you to become lazy and lethargic.
• Carbohydrates : They can be obtained from foods like wheat, rice, bread, etc. They supply the body with glucose which is converted into energy to help support bodily functions and day to day activities.

How to have a Balanced Diet?

Simple habits and ways can be followed to have a balanced diet. Eat more foods that come from trees and plants, rather than convenience foods. Convenience foods are foods that are prepared and packaged in such a way that requires very less preparation type and are almost ready to eat.  It is vital to drink plenty of water. Try to sip at least two litres per day.

Avoid having an excess of addictive liquids such as energy drinks, soft drinks, coffee and tea. Try to inculcate fruits in your breakfast and avoid having fatty and fried foods. Do not merely swallow your food, but instead chew it properly. Gulping food might lead to eating more than required or desired and is also prone to choking.
