What are 6 essential nutrients, and why does it matter?

Essential Nutrients is a substance that is required for nourishment and growth. According to World Health Organization experts, these nutrients must come from food it’s mean that your body is not able to produce these nutrients through its natural mechanism or biology.

Now I want you to think of a banana or a potato maybe a meat or a glass of milk all of these foods are made up of different amounts of nutrients like carbohydrates, proteins, fats, vitamins, minerals, and water.

In the world of nutrition, these are also referred to as the 6 essential nutrients. All of the 6 nutrients have different functions within our bodies from providing energy to repairing and healing the body and also reduce the risk of disease.

These 6 essential nutrients divided into 2 categories

  • Macronutrients
  • Micronutrients



Macronutrients are nutrients that are required in large quantity as part of our diet.

 Protein | Carbohydrate |  Fats


 1. Protein

proteins are made of smaller molecules called amino acids these are an essential part of our diet. Many people think that we simply need protein to build muscle which is one of the functions but there’s more to say about protein.

We need and use protein for the formation of structure in the body like skin and hair and also muscle.

They also plays a vital role in the transportation of oxygen around the body via our blood, besides it helps regulate the body’s use of glucose for energy and balances our blood sugar level via the hormone insulin which is built out of proteins in some cases the body also uses protein as energy.


 2. Carbohydrates

In simple terms, carbohydrates are equal to energy. Carbohydrates are broken down into glucose which is a form of sugar that uses energy to function and move the body.

carbohydrate is necessary for a healthy body Carbs fuel our body and reduce the risk of disease.


 3. Fats

Fats are sometimes called lipids. These are the biggest source of energy in our body and our body always uses a mix of carbohydrates and fats as the main source of energy to move our body.

Fat also has the function of transporting certain essential vitamins through the body like vitamins D, E, and K. If fats weren’t present these vitamins wouldn’t function properly and this could lead to problems with bone growth and eye site.



Micronutrients are the smaller portion of our food but Micronutrients are equally important as macronutrients. These little small things present in your whole food and it all depends on the kinds and types of food that you eat.

we eat the macronutrients that are calories and those can be turned into energy but they need all the micronutrients to help turn them into energy.

Vitamins |  Minerals |  Water


 4. Vitamins

Vitamins are non-caloric micronutrients that are needed in a smaller amount for normal body function. The best way to consume vitamins is through a variety of nutrient-dense foods. There is a total of 13 vitamins, which are divided into 2 categories, water-soluble which includes vitamin B’s and C; and fat-soluble vitamins A, D, E, and K.

Vitamins are necessary for healthy vision, skin, and bones. Vitamins also reduce the risk of lung and prostate cancer, and they’re powerful antioxidants. Vitamin C boosts the immune system and help the body heal.


 5. Minerals

Minerals are an inorganic, not derived by a living matter substance needed in trace to small amounts to help regulate bodily functions, such as assisting with muscle contraction and regulating enzyme activity.

Nearly All minerals except iron are absorbed in their free form. Iron helps your red blood cells and hormone creation, while zinc boosts your immune system and wound healing. Calcium helps to strengthen bones and with nerve signal transmission, maintaining healthy blood pressure, and muscle contraction and relaxation.


 6. Water

Water is an essential nutrient for the body, as the body loses water through perspiration, breathing, bowel movements, and in urine, it must be consumed regularly to maintain a sufficient level.

It has many vital functions in the body, including… Serving as a lubricant, it is a main component of saliva, which helps moisten food making it easier to swallow.

Water is a major component of blood, which transports nutrients and helps remove waste substances from all parts of the body.
