What is an AI in nutrition?
How is the Adequate Intake (AI) defined.
The AI is a recommended average daily nutrient intake level, based on experimentally derived intake levels or approximations of observed mean nutrient intake by a group (or groups) of apparently healthy people that are assumed to be adequate..
What is the relationship between the ear RDA AI and UL?
Nutrients are now assigned either an Estimated Average Requirement (EAR) and Recommended Daily Allowance (RDA) or an Adequate Intake (AI) value for each life stage category. Most nutrients also have a Tolerable Upper Intake Level (UL) to prevent the risk of adverse effects from excessive nutrient intakes.
What is the difference between RDA and AI?
The Adequate Intake (AI) is set instead of an RDA if sufficient scientific evidence is not available to calculate an EAR. The AI is based on observed or experimentally determined estimates of nutrient intake by a group (or groups) of healthy people.
Is RDI and RDA the same thing?
RDI (Reference Daily Intake) is a population-adjusted RDA based on all ages and sex groups of RDA values. It is numerically identical to the highest RDA value for any group.
