Food is the main source of energy and raw material for growth and development of the human body. Nutrition is the science of foods, the nutrients and other substances therein; their action, interaction and balance in relationship to health and disease.
The daily requirement of food for an individual depends upon growth status (age, sex, height and weight) and as human beings, we require a variety of nutrients for the growth and development of our body.

Therefore, we need a wide variety of foods to meet our basic day-to-day requirements.
