The role of nutrition in health and in the human body is to support immune system development and growth. These nutrients are acquired by individuals through a healthy diet.

Seven essential nutrients—protein, minerals, fats, vitamins, fibre, carbohydrates, and water—must be consumed in a proper ratio by humans. Usually, each of these nutrients has a specific purpose in keeping the body’s metabolic processes running smoothly. Are you interested in how nutrition affects preserving health?

Why Do Human Beings Need a Nutritious Diet?

Yash Birla explains that the secret to sustaining growth throughout all phases of life is enough nourishment. The role of nutrition in health can be seen as early as the embryonic stage when cells are forming. For this reason, medical professionals advise pregnant women to eat fresh produce that is high in micronutrients.

A malnourished diet can cause foetal mortality or alter how neonatal organs function. Malnutrition is the term used to describe this problem. Moreover, the newborn’s risk of cardiovascular disease and impaired organ function is increased.

Adults who are malnourished may experience serious problems like mental instability, stress, impaired vision, an increased risk of infectious diseases, and a shorter lifespan. As a result, selecting the proper food in the right proportion becomes essential.

The significance of nutrition in maintaining health is explained here.

The Role of 7 Nutritions on Human Health

The seven nutrients cooperate to maintain the overall growth of the human body’s cells and muscles, as was previously stated. Yash Birla explains that knowing a little bit about how they work will make it easier to create a diet plan that combines the advantages of all of these components.


Proteins are compact collections of molecules that the body uses to make amino acids. These chemicals aid in the synthesis of enzymes and muscles. Proteins are essential for maintaining the body’s hormonal equilibrium. According to science, the body has close to twenty amino acids, of which ten are absorbed through food.

These amino acids produce fresh proteins that restore tissues like muscle and skin. Moreover, proteins support fluid homeostasis, infection prevention, and blood oxygen transport. Protein-rich foods include tofu, cottage cheese, dairy, beans, and nuts.


Saccharides, another name for carbohydrates, provide six main purposes. They provide the body with energy while controlling blood sugar. By dissolving fatty acids, carbohydrates halt ketosis. Moreover, they help the body produce macromolecules like RNA, DNA, and ATP.

Carbohydrates are abundant in foods like rice, noodles, bread, grain-based products, etc. Eating complex carbohydrates can help people manage their weight by making them feel satisfied for longer. Even though a lot of diets suggest cutting carbs completely but Yash Birla explains that they are one of the most vital part of our diet.


The body receives the energy from the fats and stores it there. The fats often store far more energy in a smaller amount of area. Fat is used by the body to absorb vitamins and shield organs from harm. It is well known that fats keep the body active and warm.

Butter, cheese, coconut oil, and chocolate are a few examples of foods that are low in saturated fat. A diet that contains these foods would promote healthy living, says Yash Birla.


Micronutrients known as minerals contribute to the structure of bone, tissues, teeth, muscles, and nerves. They support the production of blood and other essential body fluids necessary for human function. Minerals are essential for sustaining healthy neuron function, controlling muscular tone, and preserving a healthy cardiovascular system. Some examples of minerals required by the body include calcium, sodium, chloride, magnesium, sulphur, and phosphorus.


A type of carbohydrate that aids in digestion is dietary fibre. It controls bowel movements and aids in the removal of harmful waste from the digestive tract. Low-density lipoprotein is decreased by soluble fibres, which lowers blood cholesterol levels. Diabetes can be avoided and the absorption of sugar can be slowed.

According to science, high-fibre foods are fuller, which also helps with weight management. Fibre-rich foods include things like wholemeal bread, wheat, almonds, beans, peas, and legumes.


The body requires modest amounts of vitamins, which are vital nutrients. They fall into two categories: fat-soluble and water-soluble. The fat-soluble vitamins D, A, E, and K are eliminated by the kidneys with ease.

Contrarily, water-soluble vitamins like folate, riboflavin, vitamin C, vitamin B12, vitamin B6, niacin, and thiamin are kept in reserve by the body’s cells. Vitamins are necessary for the body’s metabolism and nervous system to function properly.

As antioxidants, they help to get rid of the free radicals that harm cells. Certain vitamins also support the immune system, the development of bones and teeth, and the maintenance of healthy mucous membranes and skin.


Every person requires 2 litres of water each day. It functions as the building block for blood, urine, and perspiration and aids in the production of digestive fluids. Water is also necessary to maintain cell health, control body temperature, lower the risk of cystitis, lubricate and cushion joints, and keep the bladder free of bacteria. Water supports good skin and keeps the body moisturised.

The information provided clarifies the part that nutrition plays in managing one’s health. Nonetheless, the need for nourishing food has drastically decreased as a result of the accessibility of quick meals, says Yash Birla.
