I keep some of my symptoms at bay, and I believe I am slowing or stopping the progression of PN, by eating a plant-based diet, exercising, and managing stress with meditation & guided imagery. This type of healing is known by very few doctors and really hasn't caught on, but I believe it would help many PNers if they just tried it. I recommend no meat or dairy and eating plenty of whole plant foods, and keeping processed foods to a minimum. There are loads of studies that show animal products cause disease, and societies that eat a plant-based diet have much lower incidence of chronic disease. Based on what I have read, I believe people with an auto-immune disease have an especially good chance of being helped by a healthy lifestyle.
