Nutrients are the substances in food that maintain the body and make it work. A person's body cannot produce everything that it needs to function. The essential nutrients support a person's reproduction, good health, and growth. The WHO divides these crucial nutrients into two categories: micronutrients and macronutrients. This article will give you more information about where to find these nutrients and why a person needs them. 
 

Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals. Although the body only needs small amounts of them, a deficiency can cause ill health.

Macronutrients are nutrients that a person needs in more significant amounts. Macronutrients include water, protein, carbohydrates, and fats.

The six essential nutrients are vitamins, minerals, protein, fats, water, and carbohydrates. 

1. Vitamins: 

Vitamins are vital for warding off disease and staying healthy. The body needs these micronutrients to support its functions. There are 13 essential vitamins that the body needs to function properly, including vitamins A, C, B6, and D. Each vitamin plays a critical role in the body, and not getting enough of them can cause health problems and disease. These vitamins are essential for healthy vision, skin, and bones. Vitamins like vitamin C boost the immune system and help the body heal.

2. Minerals: 

Minerals help in supporting the body. They're essential for many body functions, including building strong bones and teeth, regulating metabolism, and staying adequately hydrated. Some of the most common minerals are calcium, iron, and zinc. Calcium helps with nerve signal transmission, maintaining healthy blood pressure, muscle contraction and relaxation. Iron supports your red blood cells and hormone creation, while zinc boosts your immune system and wound healing.

3. Proteins: 

Protein provides the building blocks of the body, not just for muscle. Every cell, from bone to skin to hair, contains protein. All of your hormones, antibodies and other vital substances are composed of protein. Protein is not used to fuel the body unless necessary.

4. Fats: 

Healthy fats are an essential part of a healthy diet. Fat is high in calories, but those calories are an indispensable energy source for your body. Including healthy fats in your diet can help you balance your blood sugar, decrease your risk of heart disease and type 2 diabetes, and improve your brain function. Avoid trans fats and limit your intake of saturated animal-based fats like butter, cheese, red meat, and ice cream.

5. Water:

 You can go for weeks without food, but you can't last more than a few days without water. Water is crucial for every system in your body. It's also the main thing you are made of. About 62 per cent of your body weight is water. Water improves your brain function and mood. It acts as a shock absorber and a lubricant in the body. It also helps flush out toxins, carry nutrients to cells, hydrate the body, and prevent constipation.

6. Carbohydrates: 

Don't let the low-carb craze fool you. Carbohydrates are necessary for a healthy body. Carbs fuel your body, especially your central nervous system and brain, and protect against disease. Before reaching for the white bread or pasta, remember that the type of carb you eat matters. Some carbs are healthier than others. Opt for whole grains, beans, and fibre-rich vegetables and fruits instead of refined grains and products with added sugar.

Eating a varied diet full of fruits, vegetables, healthy proteins and fats, and whole grains is the best way to get enough of these six essential nutrients. These micronutrients and macronutrients are vital for your body to function normally and stay healthy.
