Study Guide for Nutrition Now Unit 1: Key Nutrition Concepts and Terms Terms: Nutrients- Chemical substances found in food that are used by the body for growth and health.

Essential Nutrient- Substances required for normal growth and health that the body cannot generally produce in sufficient amounts, they must be obtained in the diet Nonessential Nutrients- Nutrients required for normal growth and health that the body can manufacture in sufficient quantities from other components of the diet. We do not require a dietary source of these nutrients. DRI- (Dietary Reference Intakes) - this is the general term used for the new nutrient intake standards for healthy people RDA’s- (Recommended Dietary Allowances)- They provide recommended intake levels of essential nutrients and safe upper levels of intake. The recommended daily levels of intake not only meet the nutrient needs of almost all healthy people, nut also promote health and help reduce the risk of chronic diseases AI (Adequate Intakes)- these are “tentative” RDA’s. AI’s are based on less conclusive scientific information than are the RDA’s EAR’s (Estimated Average Requirements)- These are nutrient intake values that are estimated to meet the requirements of half the healthy individuals in a group. The EAR’s are used to assess adequacy of intakes of population groups. UL’s (Tolerable upper Levels of Intake)- these are upper limits of nutrient intake compatible with health. They UL’s do not reflect desired levels of intake. Rather, they represent total, daily levels of nutrient intake from food, fortified foods, and supplements that should not be exceeded Malnutrition- means ‘poor’ nutrition and results from both inadequate and excessive availability of calories and nutrients in the body.
