Hi: I have a question about choline (part of food supplement lecithin). First, some background. According to my layman readings, choline is absorbed by the body and eventually converted into acetylcholine. One source of early symptoms for Parkinsons is the resulting imbalance between dopamine and acetylcholine due to loss of dopmanine. In fact it is this very reaction which makes anticholinergic drugs like Artane somewhat effective in the early treatment of Parkinsons. There are many sources of choline in food including oatmeal, soybeans, peanuts, eggs and milk. Now my question: Should we parkinsonians expect to react negatively to the ingestion of foods which contain choline? Should we restrict our intake of these substances?
