Nutrition quiz 1
What is the consequence of nutrient intake outside the adequate and safe range?
Consuming less than the adequate and safe range over time may lead to depletion of nutrient stores and malnutrition.
Which statement represents an appropriate use of the Dietary Reference Intake (DRI)? Fatima wants to maintain adequate iron intake, so she plans her diet to meet the EAR for iron. Sarahi is on a low-carbohydrate diet, so she is consuming less than the AMDR for percent of calories from carbohydrate. Joe heard that vitamin C is important for the immune system, so he plans to consume supplement beverages that provide double the Upper Limit. Kiko wants to get pregnant, so she takes a supplement that, combined with her diet, meets the RDA for folic acid.
Kiko wants to get pregnant, so she takes a supplement that, combined with her diet, meets the RDA for folic acid.
After her vitamin A intake has been determined, Nora observed that it was adequate and safe, meaning her intake was greater than the _____ but did not exceed the _____.
Recommended Daily Allowance; Upper Limit
Which person is potentially at risk for malnutrition?
Salma, whose intake of vitamin C is approximately the Estimated Average Requirement
Why should the Estimated Energy Requirement (EER) be used with caution? The EER is set at the low end of a group's energy needs because there is a high rate of obesity in the United States. The EER represents average energy needs, so it meets or exceeds the needs of half of the individuals in a group.. The EER is set to meet the needs of 98% of individuals in a group, so it overestimates the energy needs of most individuals. The EER does not take into account physical activity levels, so it may underestimate the energy needs of active individuals.
The EER represents average energy needs, so it meets or exceeds the needs of half of the individuals in a group..
What is the relationship between Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA)? The RDA is higher than the EAR because it accounts for a safety factor to meet the needs of most healthy individuals in a population. The RDA is set to meet the needs of 98% of healthy individuals in a group, whereas the EAR is the average needs (50%). The EAR is more appropriate for diet planning and evaluating because the RDA overestimates the needs of most healthy individuals. The RDA is used to plan the diets of the individual, whereas the EAR is used to plan the diets of the population.The EAR is established when insufficient data exist to establish an RDA.
The RDA is higher than the EAR because it accounts for a safety factor to meet the needs of most healthy individuals in a population.
The adequate and safe intake range of nutrients:
varies from one nutrient to the next; some ranges are wide; others are narrow.
When is an Adequate Intake (AI) established? when a nutrient is found to be healthful but not essential for human nutrition when a nutrient, such as sodium, is often overconsumed when ample evidence exists to determine the needs of most healthy individuals when insufficient data exist to determine an RDA for a nutrient
when insufficient data exist to determine an RDA for a nutrient
