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

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.

2. Consuming 30 g of which nutrient would provide the highest number of kcalories?

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

3. Which hormone is responsible for stimulating the gallbladder to contract and release bile?

Correct answer: B

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.

4. What is the most prevalent dietary disaccharide?

Correct answer: C

Rationale: Sucrose is the correct answer as it is the most common disaccharide found in the diet, commonly known as table sugar. Lactose is a disaccharide found in dairy products, not as prevalent in the overall diet as sucrose. Fructose is a monosaccharide commonly found in fruits and honey, not a disaccharide. Galactose is a monosaccharide commonly found in dairy products and is not the most prevalent dietary disaccharide.

5. Where does the major portion of the chemical digestion of lipids occur?

Correct answer: C

Rationale: The correct answer is C: Small intestine. The majority of lipid digestion occurs in the small intestine, where bile and pancreatic lipase are active. Lipids are broken down into fatty acids and glycerol in the small intestine. Choices A, B, and D are incorrect because the mouth and stomach play minor roles in lipid digestion, and the large intestine is mainly responsible for absorbing water and electrolytes from the indigestible food residues.
