Nutrition and digestion
A balanced diet has carbohydrates, proteins, lipids, vitamins, minerals, fibre and water. Digestive enzymes: amylase (starch→maltose), protease (protein→amino acids), lipase (lipids→fatty acids+glycerol). Bile emulsifies fats. Absorption occurs in the small intestine (villi: large surface area, thin walls, good blood supply).
