Adequate Intakes (AI):
Guidelines used when there is enough scientific data to estimate the usual
intake of a particular nutrient by a healthy population, but not enough data
to establish and RDA. The recommendations for calcium are not calculated as
AIs, rather than as RDAs, because scientists at the Food and Nutrition Board
determined there was not enough uniform data to determine an RDA. For
infants, all nutrient intakes are represented as AIs.
Daily Reference Values (DRV):
Recommended daily amounts set by the FDA for macronutrients - total fat,
saturated fat, cholesterol, total carbohydrates, dietary fiber, sodium,
potassium and protein. DRV's are based on current nutrition recommendations
for a 2,000 calorie diet. They apply to anyone age four and older. The DRV
for sodium, for example, is 2,400 milligrams, whether you are aged four,
forty-four or one-hundred four!
Dietary Reference Intakes (DRI):
The most recent series of nutrient guidelines issued by the national Academy
of Sciences' Food and Nutrition Board. Included under the DRI umbrella are
RDAs, AIs, and ULs. This series of guidelines is more comprehensive than
previous nutritent guidelines issued by the board. The figures cover healthy
individuals, from infants to pregnant women to the elderly.
Percentage of Daily Values (%DV):
Guidelines for macronutrients (total fat, saturated fat, cholesterol, total
carbohydrates, dietary fiber, sodium, potassium and protein) and
micronutrients (vitamins and minerals) established by the FDA in 1993 when
new food labels went into effect. Daily Values composed of RDIs and DRVs are
listed as percentages on Nutrition Facts labels to make the information easy
to comprehend. They reflect nutrition recommendations for a 2,000 calorie
diet and apply to everyone over age four.
Recommended Dietary Allowance (RDA):
Daily amounts of nutrients that are likely to meet the nutrient requirements
for healthy individuals. RDAs vary depending on age, gender, and other
factors. For example, healthy women between the ages of 25 and 50 should
consume 50 grams of protein per day, while pregnant women of any age should
consume 60 grams.
Reference Daily Intakes (RDI):
Recommended daily amounts for 19 essential vitamins and minerals, or
micronutrients. RDIs were established by the FDA in 1993 to take the place
of outdated USRDAs. They are based on the 1968 Recommended Dietary
Allowances and like the DRVs, apply to anyone over the age of four.
Tolerable Upper Intake Levels (UL):
The maximum dialy amounts of nutrients taht can be consumed without
producing ngative side effects in healthy people. ULs are not
recommendations, but exist as guidelines for healthy people who consume
unusually large amounts of vitamins and minerals.
U.S. Recommended Daily Allowances (USRDA):
The first nutritional guidelines set for food labels established by the FDA.
USRDAs were based on teh 1968 Recommended Dietary Allowances and are no
longer in use.
