1. Name and define RDA, AI, EAR, UL, and AMDR?
Recommended Dietary Allowances (RDA): The levels of intake of essential nutrients considered to be adequate to meet the known nutritional needs of most healthy people. First established in 1941 and revised periodically over the years.
Adequate Intake (AI): The recommended dietary intake comparable to the RDA but based on less scientific evidence.
Estimated Average Requirement (EAR): Nutrient intake value estimated to meet the requirements of half the healthy individuals in a group (i.e. pregnant women, adolescents, etc). This is used to establish the RDA.
Tolerable Upper Intake Levels (UL): The highest level of daily nutrient intake likely to pose no adverse health risks. It is used to assist in advising individuals as to the level of intake that may result in adverse effects if habitually exceeded.
Acceptable Macronutrient Distribution Range (AMDR): A range of dietary intakes for carbohydrate, fat, and protein that is associated with reduced risk of chronic disease while providing adequate nutrients.
2. Name and describe the goals of the DRI Committee?
The goals of the DRI committee are to assess dietary intake and planning diets for individuals and groups. The committee works to establish new standards to ensure adequate nutrition for most individuals in the population.
Goal 1: Setting recommended intake values (the RDA and AI)
Goal 2: Facilitating Nutrition Research and Policy- EAR. This is useful to establish nutrient requirements for different life stages and genders. The levels are set by the DRI committee based upon the role of the nutrient in the body and in reducing disease risk.
Goal 3: Establishing Safety Guidelines- UL- The DRI committee sets the Tolerable Upper Intake Levels to identify potentially toxic levels of nutrients, as available. These limits are ...
This detailed solution defines RDA, AI, EAR, UL, AMDR. It also discusses the responsibilities of the DRI Committee. It gives the recommended dietary guidelines for Americans, a general understanding of food labels, and also discusses photochemicals, flavonoids, antioxidants, phytoestrogens and lycopene and their impact on health.
