1. Which of the following foods are major sources of starch?

• A. Fruits
• B. Meats
• C. Legumes
• D. Milk

Correct answer: C

Rationale: The correct answer is C: Legumes. Legumes, such as beans and lentils, are major sources of starch, providing complex carbohydrates. Fruits (choice A) mainly provide sugars rather than starch. Meats (choice B) and milk (choice D) are not significant sources of starch as they mainly provide protein and fats, respectively. Therefore, choices A, B, and D are incorrect.

2. How is resistant starch digested in the colon?

• A. bacterial fermentation.
• B. pancreatic amylase.
• C. hydrochloric acid.
• D. villi and microvilli.

Correct answer: A

Rationale: In the colon, resistant starch is digested by bacterial fermentation. The correct answer is A. During this process, short-chain fatty acids are produced. Pancreatic amylase, as mentioned in choice B, is responsible for breaking down starch in the small intestine, not in the colon. Choice C, hydrochloric acid, functions in the stomach to aid in the digestion of proteins, not starch. Villi and microvilli, as stated in choice D, are structures in the small intestine that absorb nutrients; they do not participate in the digestion of resistant starch in the colon.

3. During lactation, where is lactose synthesized in the body?

• A. Liver
• B. Breast
• C. Kidney
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Breast. Lactose is synthesized in the breast during lactation to produce breastmilk. The liver is responsible for various metabolic functions but does not synthesize lactose. The kidney's primary role is in filtering blood and regulating electrolytes, not lactose synthesis. The pancreas is involved in producing digestive enzymes and insulin, not lactose synthesis.

4. Signs of malnutrition can appear when:

• A. nutrient reserves are depleted.
• B. nutrient intake exceeds daily needs.
• C. energy intake is restricted.
• D. caloric expenditure increases.

Correct answer: A

Rationale: The correct answer is A: 'nutrient reserves are depleted.' Signs of malnutrition manifest when the body's reserves of essential nutrients are exhausted and can no longer sustain health. Choice B is incorrect because excessive nutrient intake exceeding daily needs does not lead to malnutrition but may cause other health issues. Choice C is incorrect as restricting energy intake may lead to weight loss but not necessarily malnutrition. Choice D is also incorrect as increasing caloric expenditure does not directly cause malnutrition.

5. 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.
