Essential Nutrients for Our Body


Essential nutrients are those nutrients that our body needs to obtain from other sources as it cannot produce these on its own. Essential for proper growth and functioning of the body, these nutrients must form a part of our daily diet. Let us have a detailed look at these nutrients and various sources from which these can be obtained.

Vitamin A promotes healthy eyes, strengthens teeth and is good for skin, B Vitamins strengthen the immune system and help in the absorption of iron, Vitamin C aids in the production of collagen that provides structure to blood vessels, ligaments and bone, Vitamin D aids in maintaining calcium homeostasis. Similarly other Vitamins are also essential for the proper functioning of our body. Different vitamins can be obtained from different sources. For instance, carrot and sweet potato are a good source of Vitamin A, chilli pepper, banana, potato, whole grains and beans are a rich source of B Vitamins and Vitamin C can be obtained from red and green pepper, Brussels sprouts, strawberry, orange and guava.

The main structural component of the cells, protein aids in the building of body tissues as well as the repair of the ones that are damaged. Low-fat meat, eggs, beans and dairy products such as milk, yogurt and cheese are a good source of lean protein. Since at least 10 to 35 percent of your daily calories must come from lean protein, you must ensure that you have it in adequate amount every day.

Sodium helps in maintaining the amount of fluid outside the cells and also aids in the proper functioning of the cells, potassium aids in maintaining the amount of fluid inside and outside the cells while calcium strengthens our teeth and bones. Similarly iron, zinc and other minerals are also essential for our body. These must thus be included in our daily diet.
