What do RDAs provide guidance on?

Recommended Dietary Allowances (RDAs) are established to provide guidance on nutrient intake levels that are sufficient to prevent deficiency diseases in healthy individuals. These values are determined through scientific research and are intended to meet the nutritional needs of most individuals in a specific age and gender group. RDAs help individuals understand the minimum amount of nutrients they should consume daily to maintain health and avoid nutritional deficiencies, which can lead to various health issues.

While adequate hydration needs, daily exercise requirements, and meal timing can influence overall health and wellness, they are not the primary focus of RDAs. RDAs specifically address nutrient intake, emphasizing the importance of vitamins, minerals, proteins, and other essential nutrients that must be incorporated into one's diet to ensure optimal health.
