What food contains choline?
Choline exists widely in all kinds of foods, and it mainly exists in the cell membrane of all kinds of foods in the form of lecithin. It is rich in milk, liver, eggs, peanuts, wheat germ and soybeans, and it is also rich in lettuce and cauliflower in vegetables.

Because female estrogen can promote the synthesis of endogenous choline, women can use choline more effectively. Therefore, in 2000, China Nutrition Society revised that the AI value of choline in Chinese adults was 500 mg/d for men and 385 mg/d for women.

Extended data:

The physiological functions of choline are complex and diverse. It mainly exerts its physiological function from the following two aspects: on the one hand, it exerts its physiological function by choline itself or as a choline group needed to synthesize other substances (acetylcholine, phospholipids and lipoproteins), on the other hand, it exerts its physiological function as a methyl donor. The specific performance is as follows:

1, choline is an important component of biofilm, which ensures the signal transmission and transmembrane signal transduction of cholinergic nerves, so it is essential to maintain the integrity of cell membrane structure and function.

2. Nerve tissue is rich in sphingomyelin and phosphatidylcholine, which are necessary for myelination of nerve fibers (axons), and lack of them is not conducive to the development of nervous system. Therefore, choline plays a certain role in promoting infant brain development, improving memory function and preventing Alzheimer's disease. In addition, choline can save folic acid by participating in methionine cycle, so it plays an important role in reducing the occurrence of fetal neural tube defects.
