Food and Nutrition: Understanding the Importance of a Balanced Diet

Proper nutrition is essential for maintaining a healthy lifestyle. A balanced diet not only provides the body with the necessary nutrients to function properly, but it also helps to prevent chronic diseases such as obesity, diabetes, and heart disease. In this article, we will discuss the importance of food and nutrition, the role of a balanced diet, and how to plan our diet.

The Importance of Food and Nutrition

Food is the body’s primary source of energy. It provides the necessary nutrients to support the growth, repair, and maintenance of the body’s cells. Without proper nutrition, the body is at risk of developing various health problems.

Nutrition is the process of obtaining the necessary nutrients from food. The nutrients found in food include carbohydrates, proteins, fats, vitamins, minerals, and water. Each nutrient plays a specific role in maintaining the body’s overall health. For example, carbohydrates provide energy, proteins repair and build body tissues, and fats provide insulation and cushioning for the body’s organs.

3 Principles of food and nutrition

A balanced diet is one that provides the body with the necessary nutrients to function properly. A balanced diet should include a variety of foods from all food groups in the right proportions.

Our body requires 6 essential nutrients – proteins, carbohydrates, fats, vitamins, minerals and water. Proteins, carbs and fats are called Macronutrients and vitamins and minerals are called Micronutrients
We can get these 6 essential nutrients from 5 important food groups
1. Fruits and vegetables: These foods are high in vitamins, minerals, and fibre. They also provide the body with antioxidants, which protect the body from damage caused by free radicals.
2. Cereals/Grains: Grains are the body’s primary source of carbohydrates. They provide energy and are essential for maintaining a healthy nervous system.
3. Meat & Proteins: Proteins are essential for repairing and building body tissues. They can be found in meats, poultry, fish, beans, and nuts.
4. Dairy: Dairy products are an excellent source of calcium, essential for strong bones and teeth.
5. Fats: Fats are important for maintaining healthy skin, hair, and nails. They also provide insulation and cushioning for the body’s organs.
6. Water: Water is an essential nutrient that plays a critical role in maintaining good health. It is involved in many bodily functions such as regulating body temperature, transporting nutrients, removing waste products, absorption of food, lubricants for joints and maintaining the balance of electrolytes in the body.
Adequacy & Balance – This principle refers to the idea that the diet should provide all the necessary nutrients, in the right amounts, to maintain good health and prevent nutrient deficiencies. Adequacy can be achieved by consuming a variety of foods from all food groups in the right proportion. A balanced diet should include a balance of different foods, rather than consuming too much of one food or nutrient.

An adequate and balanced diet plan has to take into account several other important factors, e.g., age, gender, nature of physical and mental work, health status, sensitivity to a particular food, income, family food tradition, availability, accessibility, affordability, sustainability etc. The body needs different amounts of each nutrient at different stages in life. For example, children need more calcium and vitamin D than adults do, a diabetic patient needs low-carb low glycemic foods while an athlete needs lots of carbs.

Types of Diet

Mediterranean Diet – The Mediterranean Diet is a dietary pattern that is characterized by a high intake of fruits, vegetables, whole grains, nuts, seeds, and olive oil. It also includes moderate amounts of fish, poultry, and dairy products, and limited amounts of red meat and processed foods. This diet is associated with a lower risk of chronic diseases such as heart disease and type 2 diabetes.
Plant-based Diet – A plant-based diet is a diet that is based on whole, minimally processed plant foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. It typically includes a variety of fruits, vegetables, whole grains, legumes, and nuts and excludes or limits animal products such as meat, dairy, and eggs. Plant-based diets can be healthy and nutritionally adequate but should be well-planned to ensure that all essential nutrients are met.
A vegetarian diet is a diet that excludes meat and animal products but may include dairy and eggs which is also called a Lacto-oxo-vegetarian diet. There is also a Lacto-vegetarian diet, which includes dairy products but not eggs, and vegan, which excludes all animal products.
Keto diet – A ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate diet that is designed to put the body in a state of ketosis, where it burns fat for energy instead of carbohydrates. This diet is typically high in healthy fats such as coconut oil, avocado, and nuts and low in carbohydrates such as grains, fruits, and sugar.
Gluten-free Diet – A gluten-free diet is a diet that excludes gluten, a protein found in wheat, barley, and rye. This diet is necessary for people with celiac disease, gluten sensitivity, and wheat allergies.
Low-carb Diet – A low-carb diet is a diet that limits the intake of carbohydrates, typically by reducing the intake of grains, fruits, and starchy vegetables. This diet can be effective for weight loss and improving blood sugar control, but it should be well-planned to ensure that all essential nutrients are met.
Low-fat Diet – A low-fat diet is a diet that limits the intake of fats, typically by reducing the intake of foods high in saturated fats such as meat, butter, and cheese. This diet can be effective for weight loss and reducing the risk of heart disease, but it should be well-planned to ensure that all essential nutrients are met.
Intermittent Fasting – Intermittent fasting is an eating pattern that cycles between periods of eating and fasting. It can involve eating during specific hours of the day or skipping meals on certain days. This diet can be effective for weight loss and improving blood sugar control, but it should be well-planned to ensure that all essential nutrients are met.
Raw Food Diet – A raw food diet is a diet that consists of unprocessed and uncooked foods such as fruits, vegetables, nuts, and seeds. This diet is based on the belief that cooking foods destroy vital enzymes and nutrients, and it can be effective for weight loss and improving overall health, but it should be well-planned to ensure that all essential nutrients are met.
Sattvic Diet – Sattvic diet is a traditional Ayurvedic dietary practice that emphasizes the consumption of foods that are considered to be pure, natural, and nourishing for the body and mind. Sattvic diet is based on the belief that the food we eat affects not only our physical health but also our mental and emotional well-being. It emphasizes consuming whole, natural, and fresh foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. Dairy products like ghee and yoghurt and foods that are high in protein like legumes and nuts are also included. Processed, deep-fried, and spicy foods, as well as meat, fish, and eggs, are avoided. The sattvic diet is believed to promote balance, vitality, and overall well-being.
Paleo Diet – The Paleo diet is a diet that is based on the idea of eating the same types of foods that were consumed by our hunter-gatherer ancestors during the Paleolithic era. The diet includes whole, unprocessed foods such as fruits, vegetables, nuts, seeds, and lean meats and fish, and excludes processed foods, grains, legumes, dairy, and added sugars. The idea behind the diet is that by eating foods that are more similar to what our ancestors ate, we can improve our health and reduce the risk of chronic diseases. The paleo diet is also known as the “caveman diet” or the “stone age diet.”

Vegetarian vs Non-vegetarian debate

The debate over whether to eat a vegetarian or non-vegetarian diet is a complex one that can be influenced by a variety of factors, including personal beliefs, health concerns, and environmental considerations. Vegetarians, for example, may choose to avoid meat for ethical reasons, such as concerns about animal welfare, while others may do so for health reasons, such as to reduce the risk of certain diseases. Non-vegetarians, on the other hand, may argue that a diet that includes meat is more nutritionally complete and sustainable. Ultimately, the decision to follow a vegetarian or non-vegetarian diet is a personal one that should be based on individual needs, preferences, and beliefs. Non-vegetarian diet is not always better than vegetarian diet and vice-versa.

Energy Production

Energy Production from Carbohydrates:

Glucose is obtained from carbohydrates through digestion
Surplus glucose is stored in the liver and muscles in the form of glycogen, which can be broken down and converted into glucose later when needed.
Since the storage capacity of glycogen is limited. Any excess is stored as fat.
The process of converting glucose into energy begins with the breakdown of glucose through a process called cellular respiration. This process takes place in the mitochondria of cells and it is divided into two stages:
1. glycolysis
2. citric acid cycle
Glycolysis is the first stage of cellular respiration, which takes place in the cytoplasm of cells. It converts glucose into pyruvate, which is then transported into the mitochondria.
If oxygen is not present, the pyruvate is converted to lactate through a process called lactic acid fermentation. This process produces ATP and lactate as waste products. This process is used by the body during high-intensity exercise when there is not enough oxygen to support the citric acid cycle.
In the presence of oxygen, pyruvate enters the citric acid cycle or kerbs cycle where it is oxidized to produce ATP and carbon dioxide as waste products.
Adenosine triphosphate (ATP) is the primary energy currency of the cell.
The final stage of cellular respiration is the electron transport chain, where the energy from the citric acid cycle is used to generate ATP through the process of oxidative phosphorylation.

Energy Production from Fats:

Fats are obtained from the diet or stored in the body as triglycerides.
When the body needs more energy than it’s getting from glucose and glycogen, it will turn to fat storage as an energy source. This process is called lipolysis, which is the breakdown of fats in the body
Triglycerides are broken down in the adipose tissue into fatty acids and glycerol
The fatty acids enter the liver where they undergo beta-oxidation, a process that converts fatty acids into acetyl-CoA
Acetyl-CoA enters the citric acid cycle and produces ATP, carbon dioxide and water as waste products
In a state of ketosis, the liver converts fatty acids into molecules called ketone bodies, which can be used as a source of energy by the brain and other organs.

Energy Production from Proteins:

When there is a shortage of carbohydrates and fats, such as during periods of fasting or starvation, or when a person is following a very low-carbohydrate diet.
Proteins are broken down in the liver into their individual amino acids
These amino acids can then be used to produce glucose through a process called gluconeogenesis
The glucose produced through gluconeogenesis can then enter the energy production process as described above for carbohydrates.
Some of the amino acids can also be used directly in the citric acid cycle and produces ATP, carbon dioxide and water as waste products
However, it is worth noting that using protein as a primary source of energy can have negative effects on the body, as it can lead to muscle wasting, and it’s not recommended to rely on it as a primary source of energy.
In addition, when the body is in a state of catabolism, where it is breaking down tissues to release energy. This can happen in conditions like prolonged or intense exercise, injury, or chronic diseases like cancer.

It’s important to note that the body uses all three macronutrients (carbohydrates, proteins, and fats) for energy production, but the primary source of energy is carbohydrates. In the absence of carbohydrates, the body will turn to fats, and in the absence of both, the body will turn to proteins. However, it’s also worth noting that the body can shift between the different sources of energy depending on the availability of each macronutrient.

The body’s energy needs are dynamic and changing, and the body will adapt to the availability of macronutrients and use the most available source of energy. This is why, for example, a low-carb diet can lead to the body entering a state of ketosis, where it burns fat for energy instead of carbohydrates.

Creatine

Creatine is a natural compound found in small amounts in certain foods, such as red meat, and it can also be synthesized by the body. Creatine is stored in the muscles in the form of creatine phosphate, which can be converted into ATP, the primary energy currency of the cell, during intense physical activity. Supplementation with creatine has been shown to increase muscle strength and endurance, and it is commonly used by athletes and bodybuilders. But it is recommended only for professionals and when the stakes are high.

Protein

Proteins are made up of 22 amino acids, which are linked together in long chains. The body can make some amino acids called 13 non-essential amino acids, but there are others that must be obtained from food, called 9 essential amino acids.

Building and repairing tissues: Protein is essential for the growth, repair, and maintenance of muscles, bones, tendons, and other tissues.
Enzyme and hormone production: Proteins act as enzymes and hormones, helping to regulate metabolic processes and other bodily functions.
Immune function: Proteins play a critical role in the immune system, helping to protect the body from infections and other diseases.
Fluid balance: Proteins help to maintain fluid balance in the body and assist in the transport of molecules and other substances throughout the body.
Satiety: Protein is known to promote feelings of fullness and satisfaction, which can help in weight management and control.
Protein is also required for healthy skin, hair and nails.

There are many different sources of protein, both plant-based and animal-based. Animal-based proteins, such as meat, fish, eggs, and dairy products, are considered complete proteins because they contain all of the essential amino acids the body needs. Plant-based proteins, such as beans, lentils, nuts, and tofu, are considered incomplete proteins because they do not contain all of the 9 essential amino acids. However, a varied diet or combining and mixing multiple plant-based proteins called mutual supplementation can provide all necessary essential amino acids.

The recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram of body weight, but the needs may vary depending on individual factors such as age, sex, and activity level.
Physically active individuals, athletes, and bodybuilders may need more protein to support muscle growth and repair. The American College of Sports Medicine (ACSM) recommends that athletes consume 1.2 to 2.0 grams of protein per kilogram of body weight per day.
For older adults, the RDA for protein is slightly higher, at around 1.0 to 1.2 grams per kilogram of body weight per day, to support muscle mass maintenance.
Pregnant and lactating women also have increased protein needs. They should consume at least 71 grams of protein per day during pregnancy and at least 71 grams of protein per day while breastfeeding.

The modern problem of too much protein

Consuming more protein than your body needs will not necessarily lead to more muscle growth. To build muscle, you need to consume enough protein to support muscle growth, and also engage in regular strength training exercises. This helps to create a muscle-building environment, where your muscles are challenged and need to adapt by growing.

Excess protein intake can lead to kidney damage, liver dysfunction, and an increased risk of certain types of cancer.
It may cause digestive problems such as constipation and bloat.
Consuming too much protein can also lead to weight gain, as the body converts excess protein into fat.
Consuming a diet high in animal-based proteins may increase the risk of certain chronic diseases such as heart disease and colon cancer in the case of red meat.
Excess protein intake can lead to calcium loss from the bones, which over time can contribute to the development of osteoporosis. The risk of calcium loss is increased when the diet is high in animal protein, which is generally considered to be more acid-forming than plant protein.

It is important to consume a diet that includes a moderate amount of protein and also includes plenty of calcium-rich foods, such as dairy products, and leafy green vegetables.

It’s important to keep in mind that these facts are based on scientific research and studies, and they may vary based on individual factors such as age, health condition and environmental factors.

Protein Turnover rate

Protein turnover rate refers to the balance between the rate at which protein is broken down in the body (protein breakdown) and the rate at which protein is synthesized (protein synthesis). The body is constantly turning over its protein, breaking down old or damaged proteins and replacing them with new ones.

The rate of protein turnover varies depending on factors such as age, muscle mass, and activity level. In general, the rate of protein turnover is higher in individuals who have more muscle mass, as well as in individuals who engage in regular strength training exercises. This is because muscle growth and repair require the constant turnover of protein.

When there is a balance between protein breakdown and protein synthesis, the body is in a state of protein equilibrium, and muscle mass is maintained. However, if protein breakdown exceeds protein synthesis, muscle mass is lost, and if protein synthesis exceeds protein breakdown, muscle mass increases.

Strength training exercises can increase the rate of protein synthesis, which can lead to muscle growth over time. Consuming adequate amounts of protein, especially after exercise, can also support muscle growth by providing the building blocks necessary for protein synthesis.

Complete protein for Vegetarians through mutual supplementation

Vegetarians and vegans may need to pay extra attention to their protein intake to ensure they are getting all the essential amino acids they need. This is because many plant-based protein sources are considered incomplete proteins, meaning they do not contain all the essential amino acids the body needs. To ensure adequate protein intake, vegetarians and vegans can use mutual supplementation, which means combining different plant-based protein sources to make sure they are getting all the essential amino acids their body needs.

Here are some examples of mutual supplementation:

Rice and beans: Rice is low in the amino acid lysine, while beans are low in methionine. When combined, rice and beans provide a complete protein source.
Peanut butter and whole wheat bread: Peanut butter is low in methionine, while whole wheat bread is low in lysine. Together, they create a complete protein source.
Tofu and whole grain: Tofu is low in methionine and cysteine, while whole grains are low in lysine. Together they create a complete protein source.
Some plant-based foods, like quinoa, soy, and hemp seeds, are considered complete proteins.

Carbohydrates

A carbohydrate is a biomolecule made up of carbon, hydrogen, and oxygen atoms. They are one of the three main macronutrients, along with proteins and fats, that provides energy to the body. Carbohydrates can be simple, such as glucose and fructose, or complex, such as starch and cellulose. They are found in a wide variety of foods, including fruits, vegetables, grains, and sugars. Carbohydrates are the body’s primary source of energy and play a key role in metabolism.

Carbohydrates provide the body with 4 calories per gram.
Carbohydrates are classified into two categories: simple and complex.
- Simple carbohydrates are found in foods such as fruits, table sugar, and candy. They are quickly digested and absorbed by the body, leading to a rapid increase in blood sugar levels.
- Complex carbohydrates, on the other hand, are found in foods such as whole grains, legumes, and vegetables. They are broken down more slowly and provide a more sustained energy source.
Excess carbs are stored as glycogen in muscles and the liver. But the storage is limited.
Even excess glycogen is stored as fats.
Crash diets that drastically reduce carbohydrate intake can lead to fatigue, irritability, and decreased athletic performance due to low glycogen levels.
The Recommended Dietary Allowance (RDA) for carbohydrates is 130 grams per day for adult men and women.

It is important to note that a balanced diet is essential, and it’s not healthy to completely eliminate any food group like Carbohydrates. Also, it’s important to choose nutrient-dense carbohydrates like whole grains, fruits, and vegetables over processed or refined carbohydrates.

8 Important functions of water in our body

Water is essential for the proper functioning of the body. It plays a vital role in many bodily processes, including:

Regulating body temperature: Water helps to dissipate heat and keep the body cool.
Maintaining blood volume: Blood is mostly made up of water, and proper hydration helps to maintain blood volume and ensure proper circulation.
Lubricating joints: Water acts as a lubricant for joints, helping to prevent friction and wear.
Aiding digestion: Water is necessary for the breakdown and absorption of food in the digestive system.
Removing waste products: Water is needed for the kidneys to function properly and remove waste products from the body through urine.
Maintaining skin health: Adequate hydration is necessary for the skin to remain supple and elastic.
Helping the body absorb essential nutrients: Water helps to transport essential nutrients and oxygen to cells throughout the body.
Maintaining electrolyte balance: Water helps to regulate the balance of electrolytes in the body, such as sodium and potassium, which are necessary for proper muscle and nerve function.

Here are some additional facts about water and hydration:

The human body is made up of 60% water, making it essential for life.
Approximately 75% of Americans are chronically dehydrated, which can lead to a variety of health problems.
Dehydration is the most common cause of daytime fatigue.
Even mild dehydration can impair physical and mental performance.
Drinking water can help you lose weight, as it can help you feel full and prevent overeating.
Drinking water can improve your skin’s appearance by making it look more plump and youthful.
Drinking water can help to prevent headaches and migraines, as dehydration is a common trigger.
The human brain is composed of 95% water. Even a 1% drop in hydration can impair cognitive function.
A person can survive for only a few days without water, but months with food.

7 Golden Rules of Hydration

Guidelines for adequate hydration vary depending on the source, but some general recommendations include:

Thirst – Drink water even if you do not feel thirsty, as thirst is not always a reliable indicator of hydration status. If you are thirsty you are already dehydrated.
Urine Colour – Drink enough water to keep your urine clear or pale yellow in colour. It is the best indicator of hydration.
Water Loss / Sweating – Drink extra water in hot weather or when you are physically active. Monitor your weight before and after exercise to get an idea of how much fluid you need to replace.
Meals – Drink water 30 min before and 30 min after meals and avoid it during meals
Diuretics – Limit your intake of drinks that can dehydrate you, such as coffee, tea, cool drinks and alcohol. Always consume water before and after consuming diuretics.
Food Source – Eat foods that are high in water content, such as fruits and vegetables.
Electrolyte – Hydrating yourself with homemade electrolyte solution during endurance exercise will help balance the electrolyte levels in the body. Himalayan pink or black salt in fruit juices is the best alternative to commercial electrolytes.

It’s important to note that these are general guidelines and that your individual needs may vary. Also, it’s important to know that drinking too much water can lead to hyponatremia or water intoxication which can be dangerous, so it’s important to know your individual needs and drink accordingly.

Hyponatremia (water intoxication)

Hyponatremia is a condition in which the level of sodium in the blood is too low. It is caused by taking in too much water and diluting the concentration of sodium in the blood, also known as water intoxication. Sodium is an electrolyte that helps regulate the balance of fluids in and around cells. When the level of sodium in the blood is too low, it can cause the cells in the body to swell, leading to serious health problems. Symptoms of hyponatremia can include headache, nausea, vomiting, confusion, and muscle cramps. In severe cases, it can cause seizures, coma, and even death.
