1. The function of Dietary Reference Intakes (DRIs) is to designate nutrient recommendations for:

• A. different ethnic groups.
• B. all individuals.
• C. most people.
• D. most healthy people.

Correct answer: D

Rationale: The correct answer is D. Dietary Reference Intakes (DRIs) are established to provide nutrient recommendations for most healthy people. They are not specific to different ethnic groups (choice A), all individuals (choice B), or most people (choice C). DRIs aim to prevent nutrient deficiencies and chronic diseases in healthy individuals by setting intake levels for various nutrients.

2. What can excessive intakes of dietary protein do?

• A. cause vitamin deficiencies.
• B. impair kidney function.
• C. increase weight loss.
• D. decrease production of indispensable amino acids.

Correct answer: B

Rationale: Excessive intake of dietary protein can lead to impaired kidney function over time. Excessive protein consumption can put a strain on the kidneys as they work to eliminate the byproducts of protein metabolism. This can potentially lead to kidney damage. Choices A, C, and D are incorrect. Excessive protein intake is not directly linked to causing vitamin deficiencies, increasing weight loss, or decreasing the production of indispensable amino acids.

3. Individual nutrients are characterized by their ability to:

• A. work independently.
• B. fulfill specific metabolic roles.
• C. influence weight loss.
• D. improve mental status.

Correct answer: B

Rationale: The correct answer is B: 'fulfill specific metabolic roles.' Nutrients play essential roles in specific metabolic processes in the body such as energy production, tissue repair, and growth. Choice A, 'work independently,' is incorrect as nutrients often work synergistically rather than alone. Choice C, 'influence weight loss,' is incorrect as while some nutrients may support weight loss indirectly through metabolic processes, it is not their primary characteristic. Choice D, 'improve mental status,' is also incorrect as while some nutrients are important for brain health, their primary role is not specifically to improve mental status.

4. Which of the following is one of the simplest amino acids?

• A. Arginine
• B. Valine
• C. Lysine
• D. Glycine

Correct answer: D

Rationale: The correct answer is Glycine. Glycine is indeed one of the simplest amino acids as it consists of just a hydrogen atom as its side chain. Arginine, Valine, and Lysine are all more complex amino acids compared to Glycine, making them incorrect choices for this question.

5. What is the recommended dietary intake of protein for adults?

• A. 0.5 g/kg.
• B. 0.8 g/kg.
• C. 1.0 g/kg.
• D. 1.5 g/kg.

Correct answer: B

Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.
