1. 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.

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. How many amino acids are considered indispensable or essential?

• A. 9
• B. 10
• C. 12
• D. 14

Correct answer: A

Rationale: The correct answer is A: 9. Nine amino acids are considered essential or indispensable because they cannot be synthesized by the body and must be obtained through the diet. These amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices B, C, and D are incorrect as the number of essential amino acids is specifically 9, as they are crucial for various bodily functions.

4. In addition to poor eating habits, a factor that often contributes to marginal nutritional status is:

• A. dependence on caffeine.
• B. acute illness.
• C. low income.
• D. size of the family unit.

Correct answer: C

Rationale: Low income is a significant factor contributing to marginal nutritional status due to limited access to nutritious food. While dependence on caffeine or acute illness can impact health, they are not as directly linked to marginal nutrition as low income. The size of the family unit may affect food distribution within the household but is not as directly related to marginal nutritional status as low income.

5. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

• A. 130 g.
• B. 230 g.
• C. 330 g.
• D. 430 g.

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.
