Question 1

Which of the following best describes the Estimated Average Requirement (EAR) in the context of Dietary Reference Intakes (DRIs)?

Accepted Answer

EAR is the average daily nutrient intake level estimated to meet the requirements of 50% of healthy individuals.

Question 2

A nutritionist is evaluating the vitamin D intake of a group of children aged 1–3 years. If the average intake is 8 $	ext{μg}$ per day, which DRI value is most relevant for determining if this intake meets the needs of most children in this age group?

Accepted Answer

Recommended Dietary Allowance (RDA)

Question 3

Which statement about the Tolerable Upper Intake Level (UL) is correct?

Accepted Answer

UL is the highest average daily nutrient intake level likely to pose no risk of adverse health effects for almost all individuals.

Question 4

If a nutrient intake falls below the EAR but above the RDA, what does this suggest about the likelihood of deficiency in a population?

Accepted Answer

About half of the population may be at risk of deficiency.

Question 5

Which of the following is NOT a purpose of Dietary Reference Intakes (DRIs)?

Accepted Answer

To provide specific recommendations for individuals with medical conditions.

Question 6

A 25-year-old adult consumes 1200 $	ext{mg}$ of calcium daily. The UL for calcium is 2500 $	ext{mg}$ per day. What is the implication of this intake?

Accepted Answer

The intake is below the UL and is unlikely to cause adverse health effects.

Question 7

Which of the following statements is correct regarding the Acceptable Macronutrient Distribution Range (AMDR)?

Accepted Answer

AMDR is a set of recommendations for macronutrient consumption, expressed as a percentage of total energy intake.

Question 8

A child aged 1–3 years is consuming more than 1.3 $	ext{g}$ of sodium daily. According to the DRI concepts, what is the most likely health implication?

Accepted Answer

The child is at increased risk of chronic diseases.

Question 9

Which DRI value is used to assess the risk of excessive intake of a nutrient in a population?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 10

A dietitian is planning a menu for a group of healthy adults. Which DRI value should be used to ensure the menu meets the nutrient needs of nearly all individuals in the group?

Accepted Answer

Recommended Dietary Allowance (RDA)

Question 11

Which of the following scenarios best illustrates the application of the AMDR?

Accepted Answer

A nutritionist recommends that 45–65% of total daily calories come from carbohydrates.

Question 12

If the RDA for vitamin D for children aged 1–3 years is 15 $	ext{μg}$ per day, and a child consumes 8 $	ext{μg}$ per day, which statement is most accurate?

Accepted Answer

The child is below the RDA and may be at risk of deficiency.

Question 13

Which DRI value is most appropriate for evaluating whether a nutrient intake is sufficient to prevent deficiency in half of a healthy population?

Accepted Answer

Estimated Average Requirement (EAR)

Question 14

A person consumes 3000 $	ext{mg}$ of sodium daily, while the UL for sodium is 2300 $	ext{mg}$ per day. What is the most likely consequence?

Accepted Answer

The intake exceeds the UL and may increase the risk of chronic diseases.

Question 15

Which of the following is TRUE regarding the relationship between RDA and EAR?

Accepted Answer

RDA is set at a level to meet the needs of nearly all (97–98%) healthy individuals, while EAR meets the needs of 50%.

Question 16

Which of the following is NOT a correct statement about DRIs?

Accepted Answer

DRIs provide specific recommendations for individuals with diseases.

Question 17

A healthy adult is consuming 100 $	ext{g}$ of protein daily, which is 20% of their total energy intake. If the AMDR for protein is 10–35% of total energy, what does this indicate?

Accepted Answer

The intake is within the AMDR and is considered appropriate.

Question 18

Which DRI value is most useful for setting public health policies to prevent nutrient toxicity?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 19

A nutrition label states that a food provides 30% of the RDA for vitamin C per serving. What does this mean?

Accepted Answer

The food provides 30% of the amount recommended to meet the needs of nearly all healthy individuals.
