These guidelines are formulated and published by the Food and Nutrition Board of the National Academies of Sciences Engineering, and Medicine. This board is responsible for addressing concerns related to the safety, quality, and adequacy of the food supply. Additionally, they establish principles and guidelines for appropriate dietary intake and provide authoritative assessments on the connections between food intake, nutrition, and overall health

"DRI" (Dietary Reference Intakes) is the overall term used to refer to a set of reference values that serve as guidelines for planning and evaluating nutrient intake in healthy individuals. These values differ based on factors like age and gender and include the following:

• Recommended Dietary Allowance (RDA): This represents the average daily intake level necessary to meet the nutrient requirements of almost all (97-98%) healthy individuals. RDAs are often utilized to design nutritionally adequate diets for individuals
• Adequate Intake (AI): When the available evidence is insufficient to establish an RDA, the AI is determined. It represents the intake level assumed to ensure nutritional adequacy.
