Adequacy Excess Flashcards
What factors influence the amounts of nutrients we need?
The factors include:
* Age
* Gender
* Energy expenditure
* Composition of our diet
* Physiological status
These factors can affect nutrient needs significantly.
Fill in the blank: The efficacy of nutrient absorption can be affected by the _______.
[composition of our diet]
True or False: Nutrient needs are the same for all individuals.
False
Nutrient requirements vary based on individual characteristics.
What is one physiological factor that can affect nutrient needs?
Physiological status
This can include factors like pregnancy, illness, or health conditions.
How does energy expenditure relate to nutrient needs?
Higher energy expenditure typically increases nutrient needs.
This is particularly relevant for athletes or individuals with active lifestyles.
What demographic factors can affect nutrient requirements?
Demographic factors include:
* Age
* Gender
Different age groups and genders have different nutrient needs.
What is the definition of ‘Adequacy’ in nutritional context?
Adequacy refers to the sufficiency of dietary intake to meet the estimated nutritional requirements.
What are ‘Dietary Requirements’?
Dietary Requirements are the specific nutritional needs that must be met through diet.
What are ‘Physiological Requirements’?
Physiological Requirements are the nutritional needs based on the body’s physiological functions.
What is the formula for calculating Estimated Nutritional Requirement?
Estimated Nutritional Requirement = Estimated Physiologic Requirement x Estimated Proportion of Absorption.
Fill in the blank: Estimated nutritional requirement = estimated physiologic requirement x estimated _______.
proportion of absorption
What is an important element in defining the requirement?
Criteria of Adequacy
The criteria of adequacy refers to the minimum standards that need to be met for nutrient intake.
What should societies expect beyond the basic need?
More than the basic need to avoid deficiency
Societies should aim for a higher standard of nutrient intake that supports overall health and well-being.
What is necessary to allow for periods of low intake or high demand?
A degree of storage of the nutrients
Nutrient storage is crucial to prevent health detriment during times of scarcity or increased physiological needs.
True or False: Societies should only focus on avoiding nutrient deficiency.
False
Societies should strive for adequate nutrient intake that promotes health beyond merely avoiding deficiency.
Fill in the blank: Societies should expect more than the basic need to avoid _______.
deficiency
This emphasizes the importance of a holistic approach to nutrition.
What committee reviewed the Recommended Daily Amounts (RDAs) in 1987?
Panel on Dietary Reference Values of the Committee On Medical Aspects of Food Policy (COMA)
The review aimed to assess the RDAs from 1979 for energy and nutrients for various groups in the UK.
In which year did the Panel on Dietary Reference Values conduct its review?
1987
This review was focused on updating the dietary guidelines established in 1979.
How many Expert Working Groups were formed to review dietary values?
Four
The groups focused on different aspects of diet including energy, proteins, fat, carbohydrates, vitamins, and minerals.
Name one of the four Expert Working Groups established for the review.
Energy and Proteins
The other groups focused on fat and carbohydrates, vitamins, and minerals.
Fill in the blank: The Panel on Dietary Reference Values aimed to review the 1979 Recommended Daily Amounts of _______.
[energy and nutrients]
This review was essential for updating dietary recommendations in the UK.
True or False: The review conducted by COMA in 1987 included only vitamins.
False
The review included multiple categories such as energy, proteins, fat, carbohydrates, vitamins, and minerals.
What does RDI stand for?
Recommended Daily Intake
Introduced in 1969, RDI refers to the amount sufficient, or more than sufficient, for the nutritional needs of practically all healthy persons in a population.
What is the definition of RDA?
Recommended Daily Amount
Established in 1979, RDA refers to the average amount of nutrients which should be provided per head in a group of people to meet the needs of practically all members of the group.
