This is an interesting article suggesting aspartame causes Parkinson's and fibro:
Perhaps Michael J. Fox will someday realize what caused his disease, and if he does, we hope that he will use his celebrity influence to inform others about
aspartame. There are very few people who drink Diet Pepsi as frequently as Michael did, particularly at such a young age. Thus, Parkinson's disease rarely occurs in people so young. Finding the cause of these events is not difficult, except for people who are intentionally trying to avoid the obvious. Most of the organizations pretending to seek a cure, do ignore the obvious as official policy. They prefer genetic explanations, since these mean that nobody is to blame, and no reason for the funding to ever stop. Genetic explanations mean that they are certain to never find that cure, and that's money in the bank.
If the mainstream media were to spend as much time attacking excitotoxins like aspartame and MSG as they did tobacco, it would not be long before many of the major diseases, including Parkinson's disease, became a thing of the past. Fibromyalgia would disappear completely.
