What does RDA stand for in nutrition?

RDA stands for Recommended Dietary Allowance. It refers to the daily intake level of a nutrient considered sufficient to meet the requirements of most healthy individuals within a specific age and gender group. The RDA is based on scientific research and serves as a guideline to help individuals understand the appropriate amounts of various nutrients necessary to maintain good health and prevent nutritional deficiencies.

Establishing RDAs is crucial for dietary planning and nutritional education, as it helps inform food choices that support overall wellness. The RDA values can vary significantly across different nutrients, reflecting their varying roles in bodily functions and individual health needs. In contrast, the other options do not accurately capture the standard definitions or principles related to nutrient intake and dietary recommendations.
