--even those who do not have neuropathy caused by diabetes have reported sometimes experiencing exacerbations of symptoms after having consumed sugar, alcohol, or other foods high in simple carbohydrates.

Not quite sure why this is, although sugar and alcohol are known for being nerve irritants. It may just be that those with already compromised nerves are somewhat more vulnerable.

During my most severe acute neuropathy experience, I distinctly remember one major flare after a potluck pasta dinner. The experience was on reason I eventually went gluten free, though I have never tested positive for celiac on blood tests or endoscopy. I'm probably better off without all those flour products in me anyway.
