....I stand by what I have said. *Something* associated with wheat kicks my PD symptoms into overdrive to the point of incapcitation and it takes about a week for me to recover. Over the last three years or so I have deliberately exposed myself in this manner because, at first, I found this to be a bit unbelievable myself. But I eventually had to admit that it was real.

Any one can try this for themselves and "stress test" their own vulnerability. Simply avoid all exposure to wheat in any form for a few days. This is difficult because its use is so widespread. If circumstances permit I would suggest that you try to stay home and eat only simple unprocessed food for as long as possible. Then, when you can't stand it any longer, go on a carbo binge. Monitor your body's response, especially the PD symptoms. Keep notes and try to genetrate numbers where you can.

This is not the type of testing that would normally be used and "stress testing" is an appropriate label. Once it sinks in that you have been putting yourself through this type of stress it becomes a bit alarming to think about. You are intentionally risking the further loss of neurons to prove the point to yourself.

There are a number of possible explanations - all speculative. Is there something different about the wheat itself? Has modern life caused changes in our reactions? Farming methods? Permeability of membranes in the gut? Circulatory system? Brain? Do the leaky membranes result in partially digested amino acids slipping past the protective barriers and thus confuse our autoimmune response? Just how much is that slice of Wonder Bread costing us?

These are all legitimate questions that have not been answered.
