Nutrition: The science that investigates the relationship between physiological function and the essential elements of foods eaten.

Nutrients: The constituents of food that sustain humans physiologically: proteins, carbohydrates, fats, vitamins, minerals, and water.

Appetite: The desire to eat; normally accompanies hunger, but is more psychological than physiological.

Digestive Process: The process by which the body breaks down foods and either absorbs or excretes them.
