RDA (Recommended Daily Allowance)
The level of nutrient intake sufficient to meet the needs of almost all healthy individuals of a life stage and gender group.
Set at 2 standard deviations above the mean.
Adequate Intake (AI)
The approximate level of average intake by a particular group or population that appears normal.
Determined by observation or experimentation.
Tolerable Upper Intake Level (UL)
Level of nutrient that should not be exceeded to avoid adverse health effects.
Nutrient Density
Amount of micronutrients relative to the amount of macronutrients.
Kilocalorie (Kcal)
Energy or amount of heat required to raise the temperature of 1 kg water by 1 C.
Energy-Yielding Nutrients
Nutrients that are broken down in the body to yield energy.
Carbohydrates, Proteins, Lipids
Dietary Reference Index
Standards that define the amount of energy, nutrients, dietary components, and physical activities that best support life.
Estimated Average Requirement (EAR)
Amount of nutrient needed to meet the basic requirements of half the individuals in a specific group.
Minimum Daily Requirement (MDR)
Smallest exogenous supply of a nutrient that must be absorbed or consumed to prevent manifestations of a deficiency.
Nutritional Status
Condition of the body as a result of ingestion and utilization of food.
Can be normal, undernourished, obeses
Malnutrition
Pathologic state resulting from a relative lack or absolute deficiency or excess of one or more of the essential nutrients
