Want your brain to communicate seamlessly with the rest of your body? If so, you need to make sure your diet supplies you with enough choline, as choline is responsible for proper transmission of nerve impulses. Choline is also involved in gallbladder regulation and liver function. Lecithin formation, essential for the metabolism of fats, needs sufficient amounts of choline in your body. A deficiency of lecithin leads to liver and kidney disorders, high serum cholesterol levels and atherosclerosis. When sufficient amounts of choline allow for lecithin formation, it lessens the danger of excess fat in the liver. Without choline, brain function and memory are impaired. People suffering with Parkinson's disease may benefit from extra choline as it is beneficial for disorders of the nervous system. In the last decade or so, research has found a need for choline for both prevention and treatment of arteriosclerosis and the metabolism and homocysteine (high levels in the body have been associated with hardening of the arteries).
Egg yolks, lecithin (soybeans, brewer's yeast, grains, legumes, fish, wheat germ), legumes, meat, milk, soybeans and whole-grain cereals.
A deficiency could lead to fatty buildup in the liver, cardiac symptoms, gastric ulcers, high blood pressure, an inability to digest fats, kidney and liver impairment and stunted growth.
