Question Answer
Dietry Requirements- CARBOHYDRATES Carbohydates - Found in Pastas, Cereals - Broken down in cells for chemical energy to fuel functions, also muscle contractions and nerve impulses - If deficient: Paralysis, Swelling
Dietry Requirements- PROTEINS Proteins -Found in meat, fish, eggs, milk -Used for growth and repair in cells/tissues -If deficient: Anaemia, Protein deficiency disease
Dietary Requirements: FAT Fat -Oils (unsaturated), meat (saturated) -Storage of energy, protection of organs, protection from cold -Too much saturated fat: Increases concentration of cholesterol in body
Dietary Requirements- Water Water -Everywhere! Juices, Solid foods.. -Liquid that carries other substances around body to cells -If deficient: Dehydration, metabolic slowness, death
