1. A food choice equivalent to one serving from the Grains group of MyPlate is:

• A. one slice of bread
• B. 2 cups of rice
• C. 3 cups of spaghetti
• D. 4 oz of ready-to-eat cereal

Correct answer: A

Rationale: One slice of bread is a standard serving from the Grains group in MyPlate. This choice aligns with the recommended portion size for grains. Choices B, C, and D are excessive portions that do not represent a single serving according to MyPlate guidelines. 2 cups of rice, 3 cups of spaghetti, and 4 oz of ready-to-eat cereal exceed the standard serving size for grains and would provide more than one serving from this food group.

2. Which observation provides evidence that a person has good nutritional status?

• A. Small muscle mass.
• B. Normal weight-to-height ratio.
• C. Smooth tongue.
• D. Fragile skin.

Correct answer: B

Rationale: A normal weight-to-height ratio is a reliable indicator of good nutritional status as it suggests that the person is well-nourished and not underweight or overweight. Small muscle mass (choice A) can indicate malnutrition, a smooth tongue (choice C) can be a sign of vitamin deficiencies, and fragile skin (choice D) can be a sign of poor nutrition or other health issues, but they are not as direct indicators of good nutritional status as a normal weight-to-height ratio.

3. Which phase of metabolism makes growth and repair possible?

• A. digestion
• B. catabolism
• C. anabolism
• D. ketosis

Correct answer: C

Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.

4. What are dextrins?

• A. Polysaccharides.
• B. End products of starch digestion.
• C. Formed in the liver.
• D. Rapidly excreted.

Correct answer: A

Rationale: Dextrins are a type of polysaccharides formed during the breakdown of starch. Choice A is correct because dextrins are indeed polysaccharides, not the end products of starch digestion (Choice B). They are not formed in the liver (Choice C) nor rapidly excreted (Choice D).

5. 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.
