1

United States Department of Agriculture (USDA)

  • part of the federal government that provides most nutritional advice and education

2

adequacy

  • intake of a particular nutrient that ensures the highest level of physiological functioning

3

deficiency

  • intake of a particular nutrient that is insufficient to ensure physiological functioning
  • function declines

4

toxicity

  • intake of a particular nutrient beyond what is needed to meet physiological needs, and high enough to actually impair physiological functioning

5

normal districution

  • a frequency distribution in which most subjects are clustered around a central valnue
  • most biological traits are distributed in this pattern within a population
  • bell-shaped curve

6

Estimated average requirement (EAR)

  • the mean of nutrient requirements in a population

7

Recommended Dietary Allowance (RDA)

  • a level of recommended intake set at two standard deviations from the EAR.
  • Designed to meet the needs of 97 percent of the population

8

standard deviation

  • a statistical term relating the spread of values from the mean in a distribution
  • describes how tightly grouped the distribution is

9

Adequate Intake (AI)

  • A value similar to the Recommended Dietary Allowance, but without as much scientific evidence behind it as the RDA

10

Upper Limit (UL)

  • The maximum intake of a particular nutrient that is safely tolerated.

11

Pellegra

  • a disease caused by deficiency of niacin, a B vitamin
  • symptoms: Dermatitis, diarrheam dementia, and death"

12

Proportionality

  • Balance
  • The relative quantities of various food groups needed to reach adequacy

13

Saturated fat

  • A type of fat with particular chemical characteristics, generally found in animal products
  • High intakes have been linked to heart disease

14

Cholestorol

  • A type of lipid linked to heart disease

15

Nutrient-density

  • Relationship of nutrient content to energy content of a good
  • A high nutrient density food provides a large quantity of nutrients for the number of calories

  • part of the federal government that ensures safety of the food supply and regulates most food labeling

29

-ose

  • a carbohydrate and usually a sugar

30

Daily Value

  • A value for daily intake usually based on the highest RDA and a 2000 or 2500 kcal diet.  
  • Used in food labeling to estimate the contribution of that food to the total diet
