Questions: Question 6 1 pts George is a 35 -year-old athlete using nutrient supplements to give him a competitive advantage. Which of the following nutrient intake recommendations would you suggest that George become familiar with? Adequate Intakes Estimated Average Requirements Tolerable Upper Intake Levels Recommended Dietary Allowances

The answer is the fourth one: Recommended Dietary Allowances (RDA).

Explanation for each option:

1. Adequate Intakes (AI): AI is used when there is not enough evidence to develop an RDA. It is a recommended average daily nutrient intake level based on observed or experimentally determined approximations. While useful, it is not the primary guideline for someone looking to optimize nutrient intake for competitive advantage.

2. Estimated Average Requirements (EAR): EAR is the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. It is primarily used to assess the nutrient intakes of populations and to plan nutritionally adequate diets for groups, not individuals.

3. Tolerable Upper Intake Levels (UL): UL is the maximum daily intake unlikely to cause harmful effects. While important to avoid excessive intake, it does not provide guidance on the optimal intake levels for performance enhancement.

4. Recommended Dietary Allowances (RDA): RDA is the average daily dietary nutrient intake level sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. For an athlete like George, understanding the RDA is crucial as it provides a benchmark for the optimal intake of nutrients necessary to maintain health and support athletic performance.

Summary: George should become familiar with the Recommended Dietary Allowances (RDA) as it provides the most relevant information for ensuring he meets his nutrient needs to support his athletic performance.
