Lecithin also contains choline. Although it can be made in the body, the body's choline can be
added to by that obtained from food. Choline is used, amongst other things, as a component of a
neurotransmitter (chemical for relaying messages between nerve cells and between nerve and
muscle cells) called acetylcholine. There is a rare disorder of the nervous system, tardive
dyskinesia (a disorder of abnormal involuntary muscle movements) where additional dietary
choline, for example from lecithin, can be useful. In healthy people there is no particular need to
include additional choline in the diet.
It should also be noted that lecithin is not absorbed as such. It is broken down principally to
lysolecithin and fatty acid in the gut prior to absorption. Therefore, one cannot directly influence
body lecithin by having it in the diet.
It is also claimed that lecithin can dissolve fat in the body because it has been shown to act as an emulsifier and disperse fats or oils in water when used as a food, additive. Unfortunately, dietary lecithin is not effective in dissolving fat from body fat stores.
