I want to put in a word about food sensitivities. I thought oats were good for me too and have been feeling virtuous (and sleepy and overfull) when eating oatmeal my whole life. Turns out I am allergic to oats (and red pepper and milkfat). Not the kind of allergic that makes you break out in hives, but the kind of allergic where you feel sort of bloated and sleepy, or phlegmy, or stomachachy. Many docs don't even know about the food sensitivity test, but an integrative medicine doc will know. Best to keep inflammation down, especially when contending with PD.
