Which statement about choline is true?

Which statement about choline is true?

• A. Choline is not essential for human health.
• B. Choline supports cell membrane integrity and neurotransmitter synthesis; rich sources include eggs, liver, and soybeans.
• C. Choline is only found in dairy products.
• D. The body can produce all choline it needs; dietary intake is not required.

Answer: (B)

Choline is an essential nutrient that supports cell membrane integrity and neurotransmitter synthesis. It is a building block for phosphatidylcholine, a major phospholipid in cell membranes, and it provides acetylcholine, a key neurotransmitter involved in nerve signaling and muscle function. The body can make some choline, but this synthesis is not enough to meet daily needs, so dietary intake is important. Foods rich in choline include eggs, liver, and soybeans, making them common recommended sources. That combination of roles and dietary sources is what makes the statement true. The other ideas—being nonessential, being found only in dairy, or not requiring dietary intake because the body can supply all needs—don’t fit with how choline functions and how it is obtained.
