Tolerable Upper Intake Level

The UL represents the highest average level of nutrient intake that poses no risk of adverse health effects. Intakes above the UL increase risk of toxicity.

Estimated Energy Requirement

The EER represents the average intake of energy necessary to maintain energy balance for healthy individuals. Values for EER are calculated using equations that factor in age, gender, weight, height, and physical activity. Although EER may be calculated for four different activity levels (sedentary, low active, active, and very active), optimal health is consistent with “active” level or higher of physical activity. Like the EAR, the EER represents the average estimated need for individuals. This is done, rather making a generous recommendation, in order to avoid intakes that are excessive for most individuals.

Acceptable Macronutrient Distribution Ranges

The AMDR represents the range of healthful intakes for carbohydrate, fat, and protein, expressed as a percentage of total energy intake. These ranges were set at amounts determined to reduce the risk of chronic diseases, such as obesity, heart disease, diabetes, and cancer, while providing adequate nutrients. Additional recommendations are given for cholesterol, saturated fats trans fats, and added sugar.
