(25 cards)
What does DRV stand for?
Dietary Reference Values
True or False: DRVs are used to assess the nutritional adequacy of food supply.
True
What are the primary components of DRVs?
Recommended Dietary Allowance (RDA), Adequate Intake (AI), Tolerable Upper Intake Level (UL), and Estimated Average Requirement (EAR)
Fill in the blank: The _______ is the average daily dietary intake level sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals.
Recommended Dietary Allowance (RDA)
Which DRV is used when there is insufficient evidence to establish an RDA?
Adequate Intake (AI)
What does UL stand for in the context of dietary reference values?
Tolerable Upper Intake Level
True or False: The Estimated Average Requirement (EAR) is the amount of a nutrient that meets the needs of all individuals in a population.
False
What is the purpose of setting a Tolerable Upper Intake Level (UL)?
To prevent adverse health effects from excessive nutrient intake.
What is the main difference between RDA and AI?
RDA is based on sufficient evidence to meet nutrient requirements, while AI is based on observed or experimentally determined estimates.
Multiple Choice: Which of the following is NOT a component of DRVs? A) RDA B) AI C) BMI D) UL
C) BMI
Short Answer: Why are dietary reference values important for public health?
They provide guidelines for nutrient intake to promote health and prevent disease.
Fill in the blank: The DRVs are developed based on _______ studies and population data.
scientific
True or False: DRVs are the same for all age groups and genders.
False
What does the term ‘nutrient density’ refer to?
The amount of essential nutrients per unit of energy in a food.
Multiple Choice: Which population group may have different DRVs? A) Athletes B) Elderly C) Pregnant women D) All of the above
D) All of the above
What is meant by ‘nutritional adequacy’?
The extent to which dietary intake meets the nutrient needs of individuals.
Fill in the blank: The _______ provides a guideline for the average intake level of a nutrient that is expected to maintain health.
Estimated Average Requirement (EAR)
True or False: DRVs are static and do not change over time.
False
What is the role of food labeling in relation to DRVs?
To help consumers understand nutrient content and make informed food choices.
Multiple Choice: Which of the following nutrients has an established RDA? A) Vitamin C B) Fiber C) Phytochemicals D) All of the above
A) Vitamin C
Short Answer: Describe how DRVs can vary by geographic location.
They can differ based on local dietary patterns, food availability, and cultural practices.
What is the significance of using DRVs in dietary planning?
They help in creating balanced diets that meet the nutritional needs of individuals.
Fill in the blank: The DRVs are intended for _______ use rather than for individual diagnosis.
population
True or False: DRVs can be used to evaluate the dietary intake of individuals.
True
