To Charles and John and List Members Protein and Parkinsons is not a simple question. For example, how do you exclude the bias that comes from knowing what you eat. Can you be sure that the results are due to diet not suggestion? This topic was in the news in the late 1980s when J H Pincus suggested that Parkinson patients take very little protein during the day reserving the entire day's allowance for the evening meal. I put this information together a few years ago and your postings have pushed me into going through my files and getting some references for you to start with:- NETWORK the newsletter of the Parkinson Foundation of Canada had two articles in Number 43 Dec 1987 with a reference to a study by Anthony E Lang at Toronto Western Hospital's Movement Disorder Clinic AR comment-possibly not published).
