What does AI stand for in dietary intake recommendations?

In the context of dietary intake recommendations, AI stands for Adequate Intake. This term is used to indicate a level of intake for a nutrient that is assumed to ensure sufficient nutrient intake in healthy individuals. Adequate Intake levels are established when there is not enough evidence to determine a Recommended Dietary Allowance (RDA) due to a lack of research. It serves as a guideline for nutritional adequacy when precise requirements cannot be established.

The concept of Adequate Intake is important because it informs individuals and health professionals about dietary needs without the need for exhaustive scientific studies proving exact requirements for every nutrient. This makes it a practical tool for developing dietary guidelines and recommendations, allowing for public health initiatives to be based on sound nutritional principles.
