I've read ENOUGH about gluten and I never have been tested, doesn't matter to me...but I like gluten free products much better, I buy a bag of gluten free cookies now and then and live them much more than wheat cookies. Same with crackers, I don't eat pasta anymore, some mac and cheese from whole foods hot deli bar sometimes, have not bought a loaf of bread for 6+ yrs...started to buy gluten free and didn't like this heavy bread, so quit it all....I use beautiful organic lettuce leaves as a sandwich wrap.
If and when I buy a burger out, I'll get a toasted bun, but that is not often. I am not strict but I do prefer the taste overall of gluten free products.
I don't have stomach issues, I do take digestive enzymes and probiotics daily and DGL for stomach protection as I do take ibuprofen daily for OA and Fibro pain.
OA onset at 18, now 77. Fibro onset at 61, Hip Replacement "mess" 72 (nerve damage, IT band damage, shorter leg). Otherwise, pretty good health.
Most important supplement: grape seed extract
