Nutrition is the biochemical and physiological process by which an organism uses food to support its life.

Nutrition process includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion.

Human nutrition deals with the provision of essential nutrients from food that are necessary to support human life and good health. In humans, poor nutrition can cause deficiency-related diseases such as blindness, anemia, scurvy, preterm birth, stillbirth and cretinism, or nutrient excess health-threatening conditions such as obesity and metabolic syndrome. Undernutrition can lead to wasting in acute cases, and stunting of marasmus in chronic cases of malnutrition.

Supplements can never fully replace real foods. Unprocessed food is healthiest. Omega-3 fats are crucial and most people don’t get enough. There is no perfect diet for everyone.

Nutrition generally refers to the macro- and micro-nutrients essential for survival, but we do not simply eat nutrition. Instead, we eat animal- and plant-based foods without always being conscious of its nutritional value. Furthermore, various cultural factors influence and shape our taste, preferences, taboos and practices towards preparing and consuming food as a meal and diet. Biogerontological understanding of ageing has identified food as one of the three foundational pillars of health and survival. Here we address the issues of nutrition, food and diet by analyzing the biological importance of macro- and micro-nutrients including hormetins, discussing the health claims for various types of food, and by reviewing the general principles of healthy dietary patterns, including meal timing, caloric restriction, and intermittent fasting. We also present our views about the need for refining our approaches and strategies for future research on nutrition, food and diet by incorporating the molecular, physiological, cultural and personal aspects of this crucial pillar of health, healthy ageing and longevity.

1. Introduction

The terms nutrition, food and diet are often used interchangeably. However, whereas nutrition generally refers to the macro- and micro-nutrients essential for survival, we do not simply eat nutrition, which could, in principle, be done in the form of a pill. Instead, we eat food which normally originates from animal- and plant-based sources, without us being aware of or conscious of its nutritional value. Even more importantly, various cultural factors influence and shape our taste, preferences, taboos and practices towards preparing and consuming food as a meal and diet [ 1 ]. Furthermore, geo-political-economic factors, such as governmental policies that oversee the production and consumption of genetically modified foods, geological/climatic challenges of growing such crops in different countries, and the economic affordability of different populations for such foods, also influence dietary habits and practices [ 2 , 3 ]. On top of all this lurks the social evolutionary history of our species, previously moving towards agriculture-based societies from the hunter-gatherer lifestyle, now becoming the consumers of industrially processed food products that affect our general state of health, the emergence of diseases, and overall lifespan [ 1 , 4 ]. The aim of this article is to provide a commentary and perspective on nutrition, food and diet in the context of health, healthy ageing and longevity.

Biogerontological understanding of ageing has identified food as one of the three foundational pillars of health and survival. The other two pillars, especially in the case of human beings, are physical exercise and socio-mental engagement [ 5 , 6 , 7 ]. A huge body of scientific and evidence-based information has been amassed with respect to the qualitative and quantitative nature of optimal nutrition for human health and survival. Furthermore, a lot more knowledge has developed regarding how different types of foods provide different kinds of nutrition to different extents, and how different dietary practices have either health-beneficial or health-harming effects.

Here we endeavor to address these issues of nutrition, food and diet by analyzing the biological importance of macro- and micro-nutrients, and by discussing the health-claims about animal-based versus plant-based foods, fermented foods, anti-inflammatory foods, functional foods, foods for brain health, and so on. Finally, we discuss the general principles of healthy dietary patterns, including the importance of circadian rhythms, meal timing, chronic caloric restriction (CR), and intermittent fasting for healthy ageing and extended lifespan [ 8 , 9 ]. We also present our views about the need for refining our approaches and strategies for future research on nutrition, food and diet by incorporating the molecular, physiological, cultural and personal aspects of this crucial pillar of health, healthy ageing and longevity.

2. Nutrition for Healthy Ageing

The science of nutrition or the “nutritional science” is a highly advanced field of study, and numerous excellent books, journals and other resources are available for fundamental information about all nutritional components [ 10 ]. Briefly, the three essential macronutrients which provide the basic materials for building biological structures and for producing energy required for all physiological and biochemical processes are proteins, carbohydrates and lipids. Additionally, about 18 micronutrients, comprised of minerals and vitamins, facilitate the optimal utilization of macronutrients via their role in the catalysis of numerous biochemical processes, in the enhancement of their bioavailability and absorption, and in the balancing of the microbiome. Scientific literature is full of information about almost all nutritional components with respect to their importance and role in basic metabolism for survival and health throughout one’s life [ 10 ].

In the context of ageing, a major challenge to maintain health in old age is the imbalanced nutritional intake resulting into nutritional deficiency or malnutrition [ 11 , 12 ]. Among the various reasons for such a condition is the age-related decline in the digestive and metabolic activities, exacerbated by a reduced sense of taste and smell and worsening oral health, including the ability to chew and swallow [ 13 , 14 ]. Furthermore, an increased dependency of the older persons on medications for the management or treatment of various chronic conditions can be antagonistic to certain essential nutrients. For example, long term use of metformin, which is the most frequently prescribed drug against Type 2 diabetes, reduces the levels of vitamin B12 and folate in the body [ 15 , 16 ]. Some other well-known examples of the drugs used for the management or treatment of age-related conditions are cholesterol-lowering medicine statin which can cause coenzyme Q10 levels to be too low; various diuretics (water pills) can cause potassium levels to be too low; and antacids can decrease the levels of vitamin B12, calcium, magnesium and other minerals [ 15 , 16 ]. Thus, medications used in the treatment of chronic diseases in old age can also be “nutrient wasting” or “anti-nutrient” and may cause a decrease in the absorption, bioavailability and utilization of essential micronutrients and may have deleterious effects to health [ 11 ]. In contrast, many nutritional components have the potential to interact with various drugs leading to reduced therapeutic efficacy of the drug or increased adverse effects of the drug, which can have serious health consequences. For example, calcium in dairy products like milk, cheese and yoghurt can inhibit the absorption of antibiotics in the tetracycline and quinolone class, thus compromising their ability to treat infection effectively. Some other well-known examples of food sources which can alter the pharmacokinetics and pharmacodynamics of various drugs are grape fruits, bananas, apple juice, orange juice, soybean flour, walnuts and high-fiber foods (see: https://www.aarp.org/health/drugs-supplements/info-2022/food-medication-interaction.html (accessed on 13 November 2022)).

It is also known that the nutritional requirements of older persons differ both qualitatively and quantitatively from young adults [ 11 ]. This is mainly attributed to the age-related decline in the bioavailability of nutrients, reduced appetite, also known as ‘anorexia of ageing,’ as well as energy expenditure [ 12 , 17 , 18 ]. Therefore, in order to maintain a healthy energy balance, the daily uptake of total calories may need to be curtailed without adversely affecting the nutritional balance. This may be achieved by using nutritional supplements with various vitamins, minerals and other micronutrients, without adding to the burden of total calories [ 12 , 17 , 18 ]. More recently, the science of nutrigenomics (how various nutrients affect gene expression), and the science of nutrigenetics (how individual genetic variations respond to different nutrients) are generating novel and important information on the role of nutrients in health, survival and longevity.

3. Food for Healthy Ageing

The concept of healthy ageing is still being debated among biogerontologists, social-gerontologists and medical practioners. It is generally agreed that an adequate physical and mental independence in the activities of daily living can be a pragmatic definition of health in old age [ 7 ]. Thus, healthy ageing can be understood as a state of maintaining, recovering and enhancing health in old age, and the foods and dietary practices which facilitate achieving this state can be termed as healthy foods and diets.

From this perspective, although nutritional requirements for a healthy and long life could be, in principle, fulfilled by simply taking macro- and micro-nutrients in their pure chemical forms, that is not realistic, practical, attractive or acceptable to most people. In practice, nutrition is obtained by consuming animals and plants as sources of proteins, carbohydrates, fats and micronutrients. There is a plethora of tested and reliable information available about various food sources with respect to the types and proportion of various nutrients present in them. However, there are still ongoing discussions and debates as to what food sources are best for human health and longevity [ 19 , 20 ]. Often such discussions are emotionally highly charged with arguments based on faith, traditions, economy and, more recently, on political views with respect to the present global climate crisis and sustainability.

Scientifically, there is no ideal food for health and longevity. Varying agricultural and food production practices affect the nutritional composition, durability and health beneficial values of various foods. Furthermore, the highly complex “science of cooking” [ 21 ], evolved globally during thousands of years of human cultural evolution, has discovered the pros and cons of food preparation methods such as soaking, boiling, frying, roasting, fermenting and other modes of extracting, all with respect to how best to use these food sources for increasing the digestibility and bioavailability of various nutrients, as well as how to eliminate the dangers and toxic effects of other chemicals present in the food.

The science of food preparation and utilization has also discovered some paradoxical uses of natural compounds, especially the phytochemicals such as polyphenols, flavonoids, terpenoids and others. Most of these compounds are produced by plants as toxins in response to various stresses, and as defenses against microbial infections [ 22 , 23 ]. However, humans have discovered, mostly by trial and error, that numerous such toxic compounds present in algae, fungi, herbs and other sources can be used in small doses as spices and condiments with potential benefits of food preservation, taste enhancement and health promotion [ 23 ].

The phenomenon of “physiological hormesis” [ 24 ] is a special example of the health beneficial effects of phytotoxins. According to the concept of hormesis, a deliberate and repeated use of low doses of natural or synthetic toxins in the food can induce one or more stress responses in cells and tissues, followed by the stimulation of numerous defensive repair and maintenance processes [ 25 , 26 ]. Such hormesis-inducing compounds and other conditions are known as hormetins, categorized as nutritional, physical, biological and mental hormetins [ 27 , 28 , 29 ]. Of these, nutritional hormetins, present naturally in the food or as synthetic hormetins to be used as food supplements, are attracting great attention from food-researchers and the nutraceutical and cosmeceutical industry [ 27 , 30 ]. Other food supplements being tested and promoted for health and longevity are various prebiotics and probiotics strengthening and balancing our gut microbiota [ 31 , 32 , 33 ].

Recently, food corporations in pursuit of both exploiting and creating a market for healthy ageing products, have taken many initiatives in producing new products under the flagship of nutraceuticals, super-foods, functional foods, etc. Such products are claimed and marketed not only for their nutritional value, but also for their therapeutic potentials [ 10 ]. Often the claims for such foods are hyped and endorsed as, for example, anti-inflammatory foods, food for the brain, food for physical endurance, complete foods, anti-ageing foods and so on [ 34 , 35 , 36 ]. Traditional foods enriched with a variety of minerals, vitamins and hormetins are generally promoted as “functional foods” [ 37 ]. Even in the case of milk and dairy products, novel and innovative formulations are claimed to improve their functionality and health promotional abilities [ 38 ]. However, there is yet a lot to be discovered and understood about such reformulated, fortified and redesigned foods with respect to their short- and long-term effects on physiology, microbiota balance and metabolic disorders in the context of health and longevity.

4. Diet and Culture for Healthy and Long Life

What elevates food to become diet and a meal is the manner and the context in which that food is consumed [ 4 ]. Numerous traditional and socio-cultural facets of dietary habits can be even more significant than their molecular, biochemical, and physiological concerns regarding their nutritional ingredients and composition. For example, various well-known diets, such as the paleo, the ketogenic, the Chinese, the Ayurvedic, the Mediterranean, the kosher, the halal, the vegetarian, and more recently, the vegan diet, are some of the diverse expressions of such cultural, social, and political practices [ 1 ]. The consequent health-related claims of such varied dietary patterns have influenced their acceptance and adaptation globally and cross-culturally.

Furthermore, our rapidly developing understanding about how biological daily rhythms affect and regulate nutritional needs, termed “chrono-nutrition”, has become a crucial aspect of optimal and healthy eating habits [ 39 , 40 ]. A similar situation is the so-called “nutrient timing” that involves consuming food at strategic times for achieving certain specific outcomes, such as weight reduction, muscle strength, and athletic performance. The meal-timing and dietary patterns are more anticipatory of health-related outcomes than any specific foods or nutrients by themselves [ 41 , 42 , 43 , 44 ]. However, encouraging people to adopt healthy dietary patterns and meal-timing requires both the availability, accessibility and affordability of food, and the intentional, cultural and behavioral preferences of the people.

Looking back at the widely varying and constantly changing cultural history of human dietary practices, one realizes that elaborate social practices, rituals and normative behaviors for obtaining, preparing and consuming food, are often more critical aspects of health-preservation and health-promotion than just the right combination of nutrients. Therefore, one cannot decide on a universal food composition and consumption pattern ignoring the history and the cultural practices and preferences of the consumers. After all, “we eat what we are”, and not, as the old adage says, “we are what we eat”.

5. Conclusions and Perspectives

Food is certainly one of the foundational pillars of good and sustained health. Directed and selective evolution through agricultural practices and experimental manipulation and modification of food components have been among the primary targets for improving food quality. This is further authenticated by extensive research performed, mainly on experimental animal and cell culture model systems, demonstrating the health-promoting effects of individual nutritional components and biological extracts in the regulation, inhibition or stimulation of different molecular pathways with reference to healthy ageing and longevity [ 45 ]. Similarly, individual nutrients or a combination of a few nutrients are being tested for their potential use as calorie restriction mimetics, hormetins and senolytics [ 46 , 47 , 48 ]. However, most commonly, these therapeutic strategies follow the traditional “one target, one missile” pharmaceutical-like approach, and consider ageing as a treatable disease. Based on the results obtained from such experimental studies, the claims and promises made which can often be either naïve extrapolations from experimental model systems to human applications, or exaggerated claims and even false promises [ 49 ].

Other innovative, and possibly holistic, food- and diet-based interventional strategies for healthy ageing are adopting regimens such as caloric- and dietary-restriction, as well as time-restricted eating (TRE). Intermittent fasting (IF), the regimen based on manipulating the eating/fasting timing, is another promising interventional strategy for healthy ageing. Chrono-nutrition, which denotes the link between circadian rhythms and nutrient-sensing pathways, is a novel concept illustrating how meal timings alignment with the inherent molecular clocks of the cells functions to preserve metabolic health. TRE, which is a variant of the IF regimen, claims that food intake timing in alignment with the circadian rhythm is more beneficial for health and longevity [ 39 , 40 , 41 , 50 ]. Moreover, TRE has translational benefits and is easy to complete in the long term as it only requires limiting the eating time to 8–10 h during the day and the fasting window of 12–16 h without restricting the amount of calories consumed. Some pilot studies on the TRE regimen have reported improvement in glucose tolerance and the management of body weight and blood pressure in obese adults as well as men at risk of T2D. Meta-analyses of several pilot scale studies in human subjects suggest and support the beneficial effects of a TRE regimen on several health indicators [ 39 , 50 ]. Several other practical recommendations, based on human clinical trials have also been recommended for meeting the optimal requirements of nutrition in old age, and for preventing or slowing down the progression of metabolic syndromes [ 39 , 40 , 41 , 50 ].

What we have earlier discussed in detail [ 4 ] is supported by the following quote: “…food is more than just being one of the three pillars of health. Food is both the foundation and the scaffolding for the building and survival of an organism on a daily basis. Scientific research on the macro- and micro-nutrient components of food has developed deep understanding of their molecular, biochemical and physiological roles and modes of action. Various recommendations are repeatedly made and modified for some optimal daily requirements of nutrients for maintaining and enhancing health, and for the prevention and treatment of diseases. Can we envisage developing a “nutrition pill” for perfect health, which could be used globally, across cultures, and at all ages? We don’t think so” [ 4 ].

Our present knowledge about the need and significance of nutrients is mostly gathered from the experimental studies using individual active components isolated from various food sources. In reality, however, these nutritional components co-exist interactively with numerous other compounds, and often become chemically modified through the process of cooking and preservation, affecting their stability and bioavailability. There is still a lot to be understood about how the combination of foods, cooking methods and dietary practices affect health-related outcomes, especially with respect to ageing and healthspan.

An abundance of folk knowledge in all cultures about food-related ‘dos and don’ts’ requires scientific verification and validation. We also need to reconsider and change our present scientific protocols for nutritional research, which seem to be impractical for food and dietary research at the level of the population. It is a great scientific achievement that we have amassed a body of information with respect to the nature of nutritional components required for health and survival, the foods which can provide those nutritional components and the variety of dietary and eating practices which seem to be optimal for healthy survival and longevity.

Finally, whereas abundant availability of and accessibility to food in some parts of the world has led to over-consumption and consequent life-style-induced metabolic diseases and obesity, in many other parts of the world food scarcity and economic disparity continue to perpetuate starvation, malnutrition, poor health and shortened lifespan. Often, it is not a lack of knowledge about the optimal nutrition, food and diet that leads to making bad choices; rather, it is either our inability to access and afford healthy foods or our gullibility to fall prey to the exaggerated claims in the commercial interests of food producing and marketing companies. We must continue to gather more scientific information and knowledge about the biochemical, physiological and cultural aspects of nutrition, food and diet, which should then be recommended and applied wisely and globally, incorporating the social, cultural and environmental needs of all. After all, “we eat what we are”, and not merely “we are what we eat”!

The Concept of Healthy Nutrition Essay

I have always been conscious of my eating habits and health. The reason behind my consciousness is that my lifestyle and personality dictates so. Vivacious, enthusiastic enterprising are words I would use to describe myself and my busy lifestyle confirms these qualities. This means that I need to be in shape and constantly check of my energy levels for optimum productivity. Early this year I realized that, my body was slowing me down and my health was not as good as I wanted it to be. This was the driving force behind enrolling for this course.

A healthy balance diet is crucial for ensuring good health. This implies the inclusion of both macronutrients and micronutrients. The former means nutrients that are needed in relatively large amounts while the latter means nutrients needed in small amounts. Carbohydrates, proteins, water and lipids constitute the macronutrients while vitamins and minerals constitute the micronutrients.

My diet consists of high energy giving foods particularly starches and lipids. Breakfast is the most important meal of the day. Therefore, what better way to kick-start my busy schedule than with a glass of fresh fruit juice, whole meal cereals and an egg? For lunch, I usually have vegetable and cheese sandwiches that I get from the fast food nearby the college. I always make sure that the bread is whole meal because I know that it contains dietary fiber. From my classes, I have learnt that dietary fibers aid in digestion and that they make a person feel fuller for longer..In order to overcome the fast food craze I usually carry a nutrient rich snack, which I indulge in whenever I feel an appetite for deep fried foods linger. Nuts and a fruit particularly come in handy at such a time. I suppose this is the strategy I use to avoid the drive-up fast food restaurants.

In addition, I have learnt the importance of drinking lots of water. Sixty percent of the human body is water and although it does not provide energy, it helps to flush out toxic waste from the body. It also helps to dissolve and transport nutrients throughout the body. I usually take nine glasses of water daily, which is the recommended amount. According to the National health and nutrition examination survey (NHANES), the intake of foods high in micronutrients is insufficient. (CC online, 1997)This course has enabled me to pay more attention to the presence of these nutrients in my diet; hence, I have incorporated more fruits and vegetables in my diet.

In response to a fellow students posting, I would start by applauding the decision to retake this course. Not only will your grades be better, but also your diet habits will change for the better. Lachlan is going to need you to be there for him as he grows up. You want to be in good health and have the energy to take part in activities that solidify your bond. Further, you might want to progress in your studies or build a career as well as be a full time mother. Balancing between the two would need you to be at optimum. Good nutrition contributes to this end. I gather that your diet does not include a lot of drive through window fast foods visits which is commendable although occasionally it can be quite fun. Your excuse to avoid restaurants sounded hilarious if I should say so myself! Trust me, you are not alone, most people share your paranoia. However, by visiting clean restaurants of good repute it is possible to overcome the doubt. Overall, home cooked meals are just as good if not better than restaurant foods. It enables you to choose what to eat and in what proportions. So continue with the course but most importantly practice what you learn and you will experience worthwhile results.

100 Words Essay on Nutrition And Exercise

Importance of nutrition.

Eating healthy foods gives your body the energy it needs to work well. Imagine your body like a car. Without the right fuel, a car won’t run smoothly. For us, good food is our fuel. Fruits, vegetables, grains, protein, and dairy give us vitamins and energy. Eating a mix of these helps us grow and stay strong.

Benefits of Exercise

Moving and being active is just as important as eating well. When we exercise, our hearts pump faster, which is good for heart health. Playing sports, running, dancing, or even walking helps our muscles and bones get stronger and keeps our bodies fit.

Combining Nutrition and Exercise

Nutrition and exercise work together like a team. When we eat healthy and move enough, our bodies can work their best. This means we can run faster, think clearer, and feel happier. It’s important to balance good food with fun activities to stay healthy.

250 Words Essay on Nutrition And Exercise

Why eating right and moving more are important.

Eating well and staying active are like two peas in a pod; they work best together. When we eat good foods, they give us the energy to run, play, and even think better. Exercise, or moving our bodies, keeps our muscles and bones strong. It’s like when you play a game, you need both a charged controller and a working console to have fun.

The Power of Good Food

Think of your body as a car. Just as cars need the right fuel to run, our bodies need the right food to work well. Foods that are close to how they are found in nature are usually the best. These include fruits, vegetables, whole grains, nuts, and lean proteins like chicken or fish. Eating a rainbow of foods makes sure we get all the different vitamins and minerals we need.

Exercise Keeps Us Healthy

Moving around is not just for athletes; it’s for everyone. Exercise can be anything that gets you moving: walking, dancing, biking, or playing sports. When we move, our hearts beat faster, pumping more blood to our body. This keeps our heart healthy and can make us feel happier because it releases special chemicals in our brain that make us feel good.

Balance is Key

Balancing what we eat with how much we move is like walking a tightrope. Too much food and not enough exercise can lead to weight gain, while too much exercise and not enough food can make us tired and sick. It’s important to find a middle ground where we eat enough to have energy but also move enough to use that energy.

Remember, eating well and exercising are not just about looking a certain way; they’re about feeling great and being able to do all the things you love to do.

500 Words Essay on Nutrition And Exercise

When we talk about staying healthy, two key things come to mind: eating right and exercising. Just like a car needs the correct fuel to run well, our bodies need good food to work and play. Exercise is like the engine that keeps the car moving. Together, they keep our body-machine running smoothly.

Good Food for a Strong Body

Eating right means choosing foods that are good for you. Imagine your plate is a rainbow. Fruits and vegetables of different colors, like red apples and green spinach, give you a mix of vitamins. These help fight off sickness and keep your body strong. Protein from foods like chicken, beans, or nuts helps build muscles. Carbohydrates from bread and rice give you energy to run and play. Lastly, your body needs a bit of fat from foods like avocados or cheese for energy and to help your brain work well.

Exercise for Health and Happiness

Exercise is not just for athletes. It’s for everyone. Running, jumping, and playing sports make your heart strong. It’s like a muscle that gets better with practice. Other exercises like lifting weights make your muscles bigger and bones tougher. Even a simple walk with your dog or dancing in your room is good. It keeps your body moving and can make you feel happy by releasing something called endorphins, which are like tiny messengers in your body that make you feel good.

Balance is when you have just the right amount of something. Eating too much or too little can be bad for you. The same goes for exercise. Eating a lot of candy and not enough vegetables can make you feel tired and sick. Not moving enough can make your muscles weak. But too much exercise without enough rest can also be bad. It’s like playing with a toy non-stop until it breaks. Your body needs rest to fix itself and get stronger.

Teamwork: Nutrition and Exercise

Nutrition and exercise work together like a team. Good food gives you the energy to move and play. Exercise helps use that energy and makes you hungry for healthy foods. If you eat well but don’t move much, you might not feel your best. If you exercise a lot but eat only junk food, you might not have the energy to play. It’s like trying to ride a bike with flat tires; it just doesn’t work well.

Starting Good Habits Early

Starting to eat well and move more when you’re young is a great idea. It’s like learning to read or write; the sooner you start, the better you get. These habits can stick with you as you grow up. It’s easier to keep doing something you’ve always done than to start something new when you’re older.

Eating right and exercising are like best friends that help you stay healthy and strong. By making smart choices about food and moving your body every day, you can play, learn, and grow better. Remember, your body is a unique machine that needs care, and you’re the driver. You have the power to keep it running smoothly with good nutrition and exercise.

That’s it! I hope the essay helped you.
