1. Where are sugar alcohols most likely to be found?

• A. Fermented foods.
• B. Low-calorie foods.
• C. Fruits and vegetables.
• D. Fiber supplements.

Correct answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.

2. A major focus of the 2010 Dietary Guidelines is:

• A. generally healthy segments of the population
• B. the unhealthy American public
• C. vulnerable population segments
• D. ethnically diverse eating styles

Correct answer: B

Rationale: The correct answer is B: the unhealthy American public. The 2010 Dietary Guidelines primarily aimed to address the unhealthy eating habits prevalent in the American population. Choice A is incorrect as the focus was not solely on generally healthy segments of the population. Choice C is incorrect as the guidelines were not specifically tailored only for vulnerable population segments. Choice D is incorrect as the guidelines were more concerned with promoting healthy eating habits rather than ethnically diverse eating styles.

3. What does the Tolerable Upper Intake Level (UL) represent?

• A. a replacement for Recommended Dietary Allowances (RDAs).
• B. a safe level of intake for people of all ages.
• C. a potentially toxic level of intake of a nutrient.
• D. the highest amount of a nutrient that can be safely consumed.

Correct answer: D

Rationale: The Tolerable Upper Intake Level (UL) represents the highest amount of a nutrient that can be safely consumed without causing adverse health effects. It is not a replacement for Recommended Dietary Allowances (RDAs) (choice A) which are nutrient intake recommendations. While the UL is established to prevent toxicity, it is not a completely safe level for people of all ages (choice B). It is also not a potentially toxic level of intake of a nutrient (choice C), but rather the level that is unlikely to cause adverse health effects.

4. Individuals with optimal nutritional status differ from those with marginal nutritional status in their:

• A. nutrient reserves.
• B. clinical signs.
• C. body weight.
• D. risk of mental illness.

Correct answer: A

Rationale: Individuals with optimal nutritional status differ from those with marginal nutritional status in their nutrient reserves. Optimal nutritional status implies having adequate nutrient reserves, which is lacking in marginal status. Clinical signs (choice B) may or may not be present in both groups and are not the differentiating factor between optimal and marginal statuses. Body weight (choice C) can vary for reasons other than nutritional status. The risk of mental illness (choice D) is not directly related to the comparison between optimal and marginal nutritional status.

5. In an analysis of the amino acid composition of foods, the amino acid occurring in the smallest amount is called:

• A. indispensable.
• B. dispensable.
• C. complementary.
• D. limiting.

Correct answer: D

Rationale: The correct answer is D, 'limiting.' In the analysis of the amino acid composition of foods, the amino acid that occurs in the smallest amount is referred to as the limiting amino acid. This term is used because when one essential amino acid is deficient, it limits the synthesis of proteins, making it crucial in determining protein quality. Choices A, B, and C are incorrect. 'Indispensable' and 'dispensable' refer to the essentiality of amino acids, and 'complementary' does not describe the concept of the amino acid occurring in the smallest amount.
