walnuts that are beneficial to nerves is lecithin, also known as phosphatidylcholine, which provides choline to the body and forms the neurotransmitter acetylcholine, thus maintaining the function of the nervous system. Lecithin is from nuts, oil crops, but there is no lecithin in edible oil, because in the process of oil production, in order to prevent oil precipitation, lecithin was removed, so nuts, soybeans and other oil crops, egg yolks and so on is the main food source of lecithin. In addition to the formation of neurotransmitters, lecithin also has the role of blood lipid reduction.
