chapter 3 Flashcards
nutrient requirement
smallest amount of a nutrient that maintains a defined level of nutritional health
the required amount of a nutrient is generally enough to prevent
nutrients deficiency disease
many factors of nutrient requirements include
age, sex, general health status, physical activity, medication/drugs
we store some nutrients in the
liver, fat, bones
DRI
daily energy and nutrient intake standards that nutrition experts use as references
DRI developed by
Food and nutrition board of the institute of medicine (FNB)
DRI purpose
reduce risk of nutrient deficiency and excess
prevent disease
achieve optimal health
EAR
estimated average requirement
daily amount of a nutrient that meets the need of 50% of health people in a particular life stage/sex group
is EAR used as a nutrient goal for individuals
no
RDA
daily nutrient recommendations that meet the nutrient needs of 97-98% of healthy people in a particular life stage/sex group
first need ____ to establish an RDA
EAR
scientists add a margin of error to the EAR that allows
individual variations in nutrient needs and helps maintain tissue stores
AI
dietary recommendations for nutrients that scientists do not have enough information to set RDA
ex. vitamin with AI
k
UL
highest average amount of a nutrient that is unlikely to be harmful when consumed daily
EER
average daily energy intake that meets the need of a healthy person who is maintaining their weight
AMDR
macro intake ranges that are nutritionally adequate and may reduce the risk of diet-related chronic diseases
AMDR carbs: % and calories
45-65%
900-1300
AMDR protein: % and calories
10-35%
200-700
AMDR fat: % and calories
20-35%
400-700
CDRRs
nutrient intake levels that reduce chronic disease risk within a healthy population
only CCDR
sodium <2300mg
nutrient standards are used to
plan nutritious diets
elevate nutritional adequacy
commercial application
provide standards for nutritional label
RDAs and AIs are often used to
evaluate NOT PLAN an individuals diet
