Acceptable Macronutrient Distribution Range (AMDR) - Answers - A range of intakes
associated with reduced risk of chronic disease and adequate intakes of essential
nutrients.
Recommended Dietary Allowance (RDA) - Answers - Nutrient intake amount sufficient to
meet the needs of 97% to 98% of the individuals in a specific life stage.
Adequate Intake (AI) - Answers - estimates nutrient intake by a group of healthy people
when there is not enough info to set an RDA.
Tolerable Upper Intake Level (UL) - Answers - The highest daily nutrient intake level that
likely poses no health risk.
Estimated Average Requirement (EAR) - Answers - Nutrient intake value estimated to
meet the requirements of half the healthy individuals in a group.
Epidemiological study - Answers - Scientists observe how much and what kinds of foods
a group of people eat and how healthy those people are
Case-control study - Answers - Researchers compare people who do and do not have a
condition/disease, closely matching them for age/gender/key variables so that
differences in other factors will stand out
Animal Study - Answers - Researchers feed animals special diets that provide or omit
specific nutrients and then observe any changes in health.
Human Intervention (Clinical Trials) - Answers - researchers ask people to adopt a new
behavior to determine the effectiveness of such interventions on the
development/prevention of disease
Double Blind Experiment - Answers - Best; both subjects and researchers do not know
who belongs to which study group.
