Thanks for the replies. I was curious is anyone had any particular concerns about PD and vegetarian/vegan lifestyle. There is nothing online about the two being studied, other than one reference I found about the reduced risk of PD, but it is an old study.

I was given the opportunity in 1998 to take a class for one-week through my employer. All the upper rank were vegetarians. They brought in Dr. John McDougall and I, and about 10 other overweight employees, were given the opportunity to take a week off to life the lifestyle...three meals a day. I cleaned out my cupboards and converted. Never felt so good in my life as I did then and lost weight, not surprising. But, in April 2000 my company sent me on the road for a month, and since I hadn't been vegetarian for very long...only a couple of months...it was very hard to live the lifestyle, so I went "off the wagon" while I was on the road. For non-PD health reasons I am considering returning.

Dr. McDougall has a free program online to get someone moving, and a great discussion forum. If anyone is interested in reading about health and vegetarian life his website is a great place to go. He has lectured and written for most of his M.D. life, which began in Hawaii. His Hawaii story is there...where he was motivated to start his vegetarian practice.
