Get the book by Dr. Laurie K Mishley..Natural Therapies for Parkinson's Disease
It is the best book I have read, I have never met her, but it seems we have done practically the same research! Before reading the book, I was doing her book!
She suggests particular FOODS,vitamins, and COQ 10, turmeric, etc that I take....she doesn't mention fermented papaya....wish I could get the word on that to her. Perhaps someday we'll meet?? Life is amazing. She also mentions that if PD is in your family...why not change your diet now? (avoid dairy, drink green tea...etc..) Americans have unusually poor diets...full of quick processed foods, which are normally heated in a microwave oven.... You are what you eat is an old saying, but true.
