Nutrition is the process of ingestion, digestion, absorption, metabolism, transport and storage and finally, excretion of waste.

The food we intake contains nutrients as well as non-nutrients. The nutrients required by the body should be in specific amounts; too little or too much is bad, it should be the right amount to maintain good health.

Nutrition comprises of carbohydrates, fats, proteins and water which are required in large amounts. Therefore, these are called macronutrients. Vitamins and minerals are needed in smaller amounts and hence are called micronutrients.
