Q

AI?

A

Adequate Intake - The average daily nutrient intake level based on observed or experimentally- determined approximations or estimates of nutrient intake by a group (or groups) of apparently healthy people that are assumed to be adequate.

17
Q

EER?

A

Estimated Energy Requirement - The average dietary energy intake that is predicted to maintain energy balance in a healthy adult of defined age, gender, weight, height and level of physical activity, consistent with good health.

18
Q

UL?

A

Upper Limit- The highest average daily nutrient intake level likely to pose no adverse health effects to almost all individuals in the general population. As intake increases above the UL, the potential risk of adverse effects increases

19
Q

AMDR

A

Acceptable Macronutrient Distribution Range - describes the percentage of total energy coming from each macronutrient.

20
Q

SDT?
