Nutrition
Nutrition means getting all the energy that your body needs to survive. Your cells are virtually little factories that require different chemicals and compounds to produce energy. The cells need the energy to grow and fulfill their specialized functions. They get these chemicals from external sources, such as food. These chemicals are commonly known as nutrients, and we can divide them into different categories depending on their chemical structure and digestive health function. 1 In science and medicine, nutrition is the study of how the human body utilizes and responds to food. Nutritional science focuses mainly on how food is broken down in the body and how the body uses the nutrients obtained from this food. Nutrition and dietetics is the study of how people eat and how to avoid malnutrition in various populations by spreading nutrition education and nutrition facts. 2
