10 Essential Nutrients: The human body performs a variety of functions; it supports growth, repairs tissues, maintains energy as well as provides protection against diseases. But to perform all these vital functions, the human body requires energy. This energy is obtained from the food. A balanced diet that includes fruits, vegetables, whole grains, dairy products or alternatives, legumes, nuts, seeds and healthy sources of protein can help provide many of the nutrients the body needs.
Every nutrient is required in different quantities. Some nutrients are required in larger quantities, while others are required in comparatively lesser amounts. But every nutrient performs functions that are essential for the human body. Having an idea of these nutrients and their sources will help you plan a better everyday diet for yourself. Below are 10 essential nutrients your body needs and the foods where you can find them.
What Are Essential Nutrients and Why Does Your Body Need Them?
Essential nutrients are those nutrients that are required for the normal functioning of the human body such as growth, metabolism, development, energy generation as well as maintenance. These nutrients cannot be synthesized by the human body. Hence they are required to be taken from food sources, and sometimes from supplements too.
On the basis of the amount in which they are utilised by the human body, nutrients are broadly divided into
- Macronutrients: These include carbohydrates, proteins and fats, and are needed in larger quantities.
