Q: A 30-year-old male has an Estimated Energy Requirement (EER) of $2,500$ kcal/day. If his diet consists of $55\%$ carbohydrates, how many kilocalories from carbohydrates does he consume daily?

$2,500 \times 0.55 = 1,375$ kcal

Question 1

Which of the following best describes the purpose of Dietary Reference Intakes (DRIs)?

Accepted Answer

To provide a set of reference values used to plan and assess nutrient intakes of healthy people.

Question 2

Which DRI value is defined as the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group?

Accepted Answer

Estimated Average Requirement (EAR)

Question 3

A nutritionist is planning a diet for a group of healthy adults. Which DRI value should she use to ensure that the needs of nearly all individuals in the group are met?

Accepted Answer

Recommended Dietary Allowance (RDA)

Question 4

Which of the following DRIs is used when there is not enough evidence to establish an RDA?

Accepted Answer

Adequate Intake (AI)

Question 5

The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates in adults is:

Accepted Answer

$45\%$ to $65\%$ of total energy intake

Question 6

Which DRI value is intended to prevent toxicity from excessive nutrient intake?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 7

A 30-year-old male has an Estimated Energy Requirement (EER) of $2,500$ kcal/day. If his diet consists of $55\%$ carbohydrates, how many kilocalories from carbohydrates does he consume daily?

Accepted Answer

$2,500 	imes 0.55 = 1,375$ kcal

Question 8

Which of the following statements best compares EAR, RDA, and AI?

Accepted Answer

RDA is set to meet the needs of nearly all healthy individuals, while EAR meets the needs of half, and AI is used when there is insufficient evidence for an RDA.

Question 9

Which of the following DRIs applies to both macronutrients and micronutrients?

Accepted Answer

Recommended Dietary Allowance (RDA)

Question 10

A patient consumes $3,000$ mg of sodium daily. The Tolerable Upper Intake Level (UL) for sodium is $2,300$ mg. What is the potential risk for this patient?

Accepted Answer

Increased risk of adverse health effects due to excessive sodium intake.

Question 11

Which of the following is NOT a factor that affects an individual's Estimated Energy Requirement (EER)?

Accepted Answer

Genetic predisposition to taste

Question 12

If a nutrient has an EAR of $50$ mg and a standard deviation of $10$ mg, what is the RDA, assuming RDA is calculated as $RDA = EAR + 2 	imes SD$?

Accepted Answer

$70$ mg

Question 13

Which of the following best defines 'energy' in the context of nutrition?

Accepted Answer

The capacity to do work, measured in kilocalories (kcal).

Question 14

A food label states that a serving contains $9$ grams of fat. How many kilocalories from fat does this serving provide? (Use $1$ gram fat $= 9$ kcal)

Accepted Answer

$81$ kcal

Question 15

Which DRI value is most useful for evaluating the adequacy of nutrient intakes in populations, rather than individuals?

Accepted Answer

Estimated Average Requirement (EAR)
