Chapter Key Terms
Acceptable Macronutrient Distribution Ranges (AMDR)
: ranges of intakes for the energy nutrients that
provide adequate energy and nutrients and reduce the risk of chronic diseases.
Adequate Intake (AI):
the average daily amount of a nutrient that appears sufficient to maintain a
specified criterion; a value used as a guide for nutrient intake when an RDA cannot be determined.
AN-throw-poe-MET-rick): relating to measurement of the physical characteristics of the
body, such as height and weight.
a measure of
energy. Energy provided by foods and beverages is measured in
(1000 calories equal 1 kilocalorie), abbreviated
One kcalorie is the amount of
