Choline is a water-soluble nutrient essential to the human diet. Sources of choline include meat, milk, eggs, legumes and some vegetables. Choline is grouped with the B vitamins although it is not technically a vitamin. Choline and its metabolites are necessary for cell membrane structure, cell signaling, nerve impulse transmission and fat transportation and metabolism. Vegetarians who do not consume milk or eggs need to consume a variety of vegetables high in choline in order to avoid a deficiency.
Your body is capable of synthesizing a small amount of choline, however in order to maintain health you need choline in your diet as well. The Institute of Medicine recommends men consume 550 mg of choline daily and women consume 425 mg. According to the Linus Pauling Institute, choline deficiency is associated with increased risk of heart disease, cancer and pregnancy complications.
