6 major classes of nutrients are:

Carbohydrates (CHO)

Energy-yielding macronutrient Contain Carbon, Hydrogen & Oxygen Make up the majority of most diets

Water (H2O)

Non-energy yielding (no calories) Facilitates metabolic reactions Helps regulate body temperature Makes up ~60% of adult body mass

Vitamins (A, B, C, D, E...)

Non-energy yielding micronutrient Facilitate metabolic reactions (release of energy from carbohydrate, fat, protein)

Minerals (copper, iron, cobalt, chromium)

Non-energy yielding micronutrient Indestructible chemical elements 16 known essential minerals

Lipids (Fats)

Energy-yielding macronutrient Protective: insulates, cushions, storage nutrient Major component of cell membranes, immunity

Proteins

Energy-yielding, organic, macronutrient Building blocks for growth and repair Contain Carbon, Hydrogen, Oxygen & Nitrogen
