EXAM QUESTIONS
QUESTION 1
Which of the following best describes the purpose of Adequate Intake (AI) in human nutrition?
A) To establish the minimum recommended daily intake of essential micronutrients
B) To set a daily reference value for nutrients with insufficient research data
C) To determine the upper tolerable intake level of a specific nutrient
D) To identify the optimal range for a nutrient's dietary allowance
CORRECT ANSWER
B) To set a daily reference value for nutrients with insufficient research data
RATIONALE: Adequate Intake (AI) is a term used to describe the daily intake value for a nutrient when there is
insufficient research to establish a Estimated Average Requirement (EAR). This value is typically established based on
average nutrient intake levels in healthy populations. The correct answer, B, accurately reflects the role of AI in human
nutrition, distinguishing it from other related concepts like the minimum recommended daily intake (A) or upper
tolerable intake levels (C) and dietary allowances (D).

, QUESTION 2
What is the primary purpose of Estimated Average Requirements (EARs) in nutritional assessments?
A) To establish a maximum daily intake for a nutrient to prevent adverse health effects.
B) To determine the adequate intake level for a nutrient that meets the needs of 50% of individuals in
a group.
C) To set a minimum daily intake for a nutrient to prevent deficiencies in a population.
D) To identify the optimal intake level for a nutrient that maximizes health benefits.
CORRECT ANSWER
B) To determine the adequate intake level for a nutrient that meets the needs of 50% of individuals in a
group.
RATIONALE: Estimated Average Requirements (EARs) are used to establish the adequate intake level for a nutrient that
meets the needs of 50% of individuals in a group. This allows for the evaluation of the adequacy of diets in a
population, making option B the correct answer. Options A and C are incorrect because EARs do not set maximum or
minimum daily intakes, and option D is incorrect because EARs are not focused on maximizing health benefits.
QUESTION 3
A candidate should identify that Tolerable Upper Intake Levels (ULs) specify the maximum daily
intake of a nutrient that most individuals can consume without experiencing adverse health effects.
A) The recommended dietary allowance for a specific nutrient.
B) The upper limit of a nutrient that people generally require for adequate health.
C) The maximum amount of a nutrient most people can safely consume on a daily basis.
D) The average intake of a nutrient in a healthy population.
CORRECT ANSWER
C) The maximum amount of a nutrient most people can safely consume on a daily basis.
RATIONALE: This option correctly identifies that Tolerable Upper Intake Levels (ULs) specify the maximum daily intake
of a nutrient that most individuals can consume without adverse health effects. Options A and B are incorrect as they
describe different nutritional concepts, and option D refers to average intake rather than a specific upper limit.
QUESTION 4
Which of the following is a characteristic of the Recommended Dietary Allowance (RDA)?
A) The maximum daily nutrient intake to prevent health complications in 2% of individuals.
B) The average daily nutrient intake of a healthy population.
C) The daily nutrient intake amount sufficient to meet the needs of 97-98% of individuals in a life
stage.
D) The minimum daily nutrient intake to avoid nutrient deficiencies in 50% of individuals.
CORRECT ANSWER
C) The daily nutrient intake amount sufficient to meet the needs of 97-98% of individuals in a life stage.
