Detailed explanation-2: -We need energy to move, grow, and function. This energy comes from food. Energy is stored in the chemical bonds of the molecules that make up the food we eat. Through digestion our bodies break down food into tiny pieces (molecules such as proteins, carbohydrates, and fats).

The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Detailed explanation-5: -Nutrition is a critical part of health and development. Better nutrition is related to improved infant, child and maternal health, stronger immune systems, safer pregnancy and childbirth, lower risk of non-communicable diseases (such as diabetes and cardiovascular disease), and longevity.
