Which enzyme is most essential for the digestion of triglycerides found in butterfat?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct Answer: A
Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

A pregnant woman has applied to use WIC services to supplement her food intake. The WIC program would provide vouchers for _____ in this situation.
- A. lean beef
- B. fruit-flavored yogurt
- C. whole grain bread
- D. refried beans
Correct Answer: C
Rationale: The correct answer is C: whole grain bread. The WIC program aims to provide nutritious foods to support a healthy diet during pregnancy. Whole grain bread is a good source of fiber and essential nutrients. Choice A, lean beef, is a protein source but may not be as versatile as whole grain bread in providing a variety of nutrients essential during pregnancy. Choice B, fruit-flavored yogurt, may contain added sugars and may not offer the same level of essential nutrients as whole grain bread. Choice D, refried beans, is a good source of protein and fiber, but whole grain bread is often a staple recommended in pregnancy for its nutritional benefits.
