chapter 3 - planning nutritious diets - Answer-
What is the difference between RDA and an AI? - Answer- RDA are standards for
recommending daily intakes of several nutrients. RDAs meet the nutrient needs of
nearly all healthy individuals (about 98%) in a particular life stage/sex group. In some
instances, scientists set AIs for certain nutrients because they do not have enough
information to establish RDAs for them. An AI represents a groups average daily intake
that appears to be adequate for health.
Describe how scientists establish the RDA for nutrient. - Answer- To establish an RDA
for a nutrient, nutrition scientist first determine its estimated average requirement. Then
scientist add a "margin of safety" amount to the EAR that allows for individual variations
in nutrient needs and helps maintain tissue stores.
Explain how an EER differs from an RDA or AI - Answer- The EER is more specific than
RDAs or AIs because it take into account the person's physical activity level, height, and
weight, as well as sex and life stage. Furthermore, the EEr does not include an
additional number of kilocalories to serve as a margin of safety.
Discuss how registered dietitian nutritionists, pharmaceutical companies, and the FDA
use nutrient standards. - Answer- Dietitians refer to DRIs as standards for planning
nutritious diets for groups of people and evaluating the nutritional adequacy of a
population's diet. Pharmaceutical companies refer to DRIs when developing formulas
that replace brest milk or regular foods. For, nutrition labeling purposes, the FDA uses
RDAs to develop Daily Values (DVs).
requirement - Answer- smallest amount of a nutrient that maintains a defined level of
nutritional health
, Dietary Reference Intakes (DRIs) - Answer- various energy and nutrient intake
standards for Americans
Estimated Average Requirement (EAR) - Answer- amount of a nutrient that meets the
needs 50% of healthy people in a life stage/ sex group.
Reccomended Dietary Allowance (RDA) - Answer- daily nutrient intake levels that meet
the nutritional needs of 97 to 98% of healthy people in a life stage/sex group
Adequate Intake (AI) - Answer- Dietary recommendations for nutrients that scientists do
not have enough information to set RDAs
what is the level of nutrient X - Answer- low intake = high risk of deficiency
RDA/AI middle = low risk of deficiency or toxicity
high intake = high risk of toxicity
Tolerable Upper Intake Level (UL) - Answer- highest average amount of a nutrient that
is unlikely to harm most people when the amount is consumed daily.
Estimated Energy Requirement (EER) - Answer- Average daily energy needs of healthy
people maintaining their weight; consider physical activity level, height, weight, and life
stage/sex group.
Acceptable Macronutrient Distribution Range (AMDR) - Answer- range of carbohydrate,
fat, and protein intakes that provide adequate amounts of micronutrients and may
reduce the risk of developing certain certain diet-related chronic diseases.
What are the AMDR for an adult (2000 Kcal/day) - Answer- Carbs intake: 45 - 65
(calories 900 - 1300)
Protein intake: 10 -35 (calories 200 - 700)
Fat* intake: 20 - 35 (calories 400 - 700)
Chronic Disease Risk Reduction Intake (CDRR) - Answer- Nutrient intakes levels that
reduce the risk chronic disease risk withing a healthy population
enrichment - Answer- replacement of some nutrients that were removed during
processing
fortification - Answer- addition of any nutrients to food to boost its nutritional value
solid fats - Answer- fats that are fairly hard at room temp
ultra-processed food - Answer- foods that contain numerous ingredients, which were
added to improve desirable characteristics
