1. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?

• A. Old Recommended Dietary Allowances (RDA)
• B. Estimated Average Requirement (EAR)
• C. New Recommended Dietary Allowances (RDA)
• D. Tolerable Upper Intake Level (UL)

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.

2. How many calories are contained in a food that has 15 grams of carbohydrates, 4 grams of protein, and 10 grams of fat?

• A. 106
• B. 124
• C. 166
• D. 202

Correct answer: C

Rationale: To calculate the total calories in a food item, you can use the following conversions: every 1 gram of carbohydrate provides 4 calories, 1 gram of protein provides 4 calories, and 1 gram of fat provides 9 calories. Therefore, for this food item, multiply 15 grams of carbohydrates by 4 calories/gram, 4 grams of protein by 4 calories/gram, and 10 grams of fat by 9 calories/gram. The calculation would be (15 * 4) + (4 * 4) + (10 * 9) = 60 + 16 + 90 = 166 calories. Choice A (106) is incorrect because it does not consider the calories from fat. Choice B (124) is incorrect as it underestimates the calories by not including all macronutrients. Choice D (202) is incorrect as it overestimates the calories by adding up the values incorrectly.

3. Which food would benefit an anemic patient by increasing their intake?

• A. Beef
• B. Apples
• C. White bread
• D. Fish

Correct answer: A

Rationale: An anemic patient would benefit from increasing their intake of beef. Beef is an excellent source of heme iron, which is critical for treating anemia. Heme iron is absorbed more readily by the body compared to non-heme iron found in plant-based foods. Apples and white bread, while healthy, do not contain significant amounts of heme iron. Fish, although it does contain iron, it's non-heme iron, which is not as efficiently absorbed by the body as heme iron, hence less effective in treating anemia.

4. A diet high in which nutrient can lead to increased risk of developing kidney stones?

• A. Fiber
• B. Protein
• C. Carbohydrates
• D. Unsaturated fats

Correct answer: B

Rationale: High protein intake can increase the risk of kidney stones due to elevated calcium excretion.

5. James wants to know the recommended intake for iron for his gender and age. Which of the following would provide the best answer for James?

• A. EAR
• B. UL
• C. RDA
• D. DV

Correct answer: C

Rationale: The Recommended Dietary Allowance (RDA) is the correct answer for James because it provides the daily intake level that meets the nutrient needs of most healthy individuals in a specific age and gender group. Choice A, EAR (Estimated Average Requirement), represents the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. Choice B, UL (Tolerable Upper Intake Level), is the maximum daily intake unlikely to cause adverse health effects. Choice D, DV (Daily Value), is a general guide used for food labeling that represents how much a nutrient in a serving of food contributes to a daily diet based on a 2000-calorie daily intake.
