There are 3 main ideas that are guiding research: understanding the effects of over-nutrition (obesity) and micronutrient supplementation, multiple interacting nutrients, nutrigenomics. *each class has different chemical characteristics that allow them to fulfill their roles in metabolism* Macronutrients vs micronutrients: macronutrients, need lots-e providing nutrients, carbohydrates (cho), lipids, proteins, micronutrients, need a little, vitamins, minerals, other, water-highest requirements by weight, of all nutrients. Organic vs inorganic: organic, contain carbon structure, carbohydrates, lipids, proteins, vitamins. Essential nutrient: a chemical that is required for optimal metabolism, but cannot be synthesized either at all or cannot be synthesized rapidly enough, to meet the needs of an animal or human for one or more physiological functions. Purified diet experiment (uses diets devoid of the nutrient of interest)
