Jim, I was a vegetarian (not vegan, I eat eggs & dairy, mostly Greek yogurt) for about 10 years, but my health wasn't great. I decided about a year before my PD diagnosis in 2007 that we all need Omega 3, preferably from fish oil (not veg sources, which aren't as good). So I started eating salmon & still do. I eat a wide variety of vegies, which I love, including beans, lentils, greens, mushrooms, peppers, grains, all fruits, plus fish & eggs, but try to minimize cheese, sugars, white rice, white potatoes, etc.

Now 5 years since my diagnosis, I keep very active with yoga, dance, aquatics, chorus, support groups, etc., and I'm doing pretty well, except for a really big annoying tremor which no meds so far tried have controlled. I'm very conservative about meds, because I believe their side effects can outweigh benefits, at least for some people. Sometimes it's hard to tell which symptoms are due to disease & which to meds. For example, I take very low but frequent Sinemet doses, because I got crippling dystonia with larger doses. Tried Amantadine, but got intolerable insomnia. Didn't like Mirapex. My MDS Neurologist tells me not to worry yet about protein with my Sinemet. I take Vit. D, turmeric, CoQ10, creatine, resveratrol, fish oil, ibuprofen, etc.

Hope this is helpful. We're all so different, it's hard to say what works best for any given person. But I figure you can't go wrong with good food, good support, good attitude, and good exercise! Good luck!
