SECTION 1: NUTRITION FUNDAMENTALS & DIETARY GUIDELINES Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 19-year-old college student reviews her daily food log and notices she consumes roughly
350 kcal from sweetened coffee drinks, energy bars, and flavored yogurt. According to the
current Dietary Guidelines for Americans, what percentage of her total daily calories should
come from added sugars to stay within the recommended limit?
A. Less than 15% of total daily calories
B. Less than 10% of total daily calories ✓ CORRECT
C. Less than 20% of total daily calories
D. Less than 5% of total daily calories
Correct Answer: B
Rationale: The Dietary Guidelines for Americans recommend that added sugars contribute
less than 10% of total daily calories to reduce the risk of obesity, type 2 diabetes, and
cardiovascular disease. Choice A incorrectly raises the threshold to 15%, which would
exceed the evidence-based limit and increase chronic disease risk. Students should track
hidden added sugars in beverages and packaged snacks, as these are the primary sources of
excess intake in young adults.
Question 2 of 50
A registered dietitian is counseling a 34-year-old client who wants to improve his vegetable
intake but admits he only eats iceberg lettuce and occasional tomato sauce on pizza. The
dietitian explains that the USDA MyPlate vegetable group is divided into five subgroups.
Which of the following subgroups is the client most clearly neglecting in his current eating
pattern?
,A. Starchy vegetables such as potatoes and corn
B. Red and orange vegetables such as carrots and sweet potatoes
C. Beans and peas as a vegetable choice
D. Dark-green vegetables such as spinach and broccoli ✓ CORRECT
Correct Answer: D
Rationale: Dark-green vegetables provide unique nutrients including vitamin K, folate, and
antioxidants that iceberg lettuce and tomato sauce cannot adequately supply, making this
subgroup the most neglected in the client's pattern. Choice B is tempting because tomatoes
are technically red vegetables, but tomato sauce on pizza is minimal and processed, while
the client completely lacks dark-green options. When counseling clients, emphasize that
rotating through all five vegetable subgroups ensures a broader spectrum of micronutrients
and phytochemicals.
Question 3 of 50
A grocery shopper examines the Nutrition Facts label on a box of cereal and sees that one
serving contains 15% of the Daily Value for dietary fiber. Based on standard food labeling
regulations, what daily caloric intake is the % Daily Value system designed to reference?
A. 2,000 calories per day ✓ CORRECT
B. 2,500 calories per day
C. 1,800 calories per day
D. 2,200 calories per day
Correct Answer: A
Rationale: The % Daily Value on Nutrition Facts labels is calculated based on a 2,000-calorie
diet, which represents general dietary advice for adults and serves as the uniform reference
point for all listed nutrients. Choice B confuses the calorie reference with the daily value for
certain nutrients or misapplies higher energy needs. Consumers should remember that %DV
is a relative guide; individuals with higher or lower caloric needs must adjust their personal
targets accordingly.
Question 4 of 50
A 45-year-old office worker with a family history of obesity is trying to lose weight by
replacing his usual afternoon vending machine snack of chips and soda with a small handful
of almonds and a piece of fruit. Which nutrition concept best describes this dietary
substitution?
A. Increasing discretionary calorie allowance
B. Reducing total carbohydrate load
C. Improving nutrient density ✓ CORRECT
D. Maximizing glycemic index
, Correct Answer: C
Rationale: Nutrient density refers to foods that provide substantial vitamins, minerals, and
beneficial compounds relative to their calorie content, which almonds and fruit deliver
compared to chips and soda. Choice A misapplies the concept because discretionary
calories are the extra calories allowed after meeting nutrient needs, not the strategy of
swapping empty-calorie foods for nutrient-rich ones. This substitution also increases satiety
through fiber and healthy fats, supporting sustained energy and better portion control later in
the day.
Question 5 of 50
A nutrition professor explains to her introductory class that the Dietary Reference Intakes
include several distinct categories used for different purposes in public health and clinical
settings. Which DRI category represents the average daily nutrient intake level estimated to
meet the requirements of half the healthy individuals in a particular life stage and gender
group?
A. Recommended Dietary Allowance (RDA)
B. Estimated Average Requirement (EAR) ✓ CORRECT
C. Adequate Intake (AI)
D. Tolerable Upper Intake Level (UL)
Correct Answer: B
Rationale: The EAR is defined as the intake level that meets the needs of 50% of individuals in
a specified group and is primarily used to assess nutrient adequacy in populations and plan
group diets. Choice A is incorrect because the RDA is set at a higher level designed to meet
the needs of 97–98% of healthy individuals, not merely half. Understanding the distinction
between EAR and RDA is essential for interpreting nutrition research and public health
surveys accurately.
Question 6 of 50
A public health campaign in a rural Kentucky community aims to reduce the incidence of
diet-related chronic diseases among adults aged 40 to 65. Which key recommendation from
the Dietary Guidelines for Americans should be emphasized as the foundation for this
initiative?
A. Follow a healthy dietary pattern at every life stage ✓ CORRECT
B. Eliminate all dietary fat to prevent heart disease
C. Consume a high-protein, low-carbohydrate diet for all adults
D. Avoid all grains to reduce inflammation
Correct Answer: A
