Celiac does indeed exist. And it is serious. It’s just not as common as the food faddists would have us believe.
But...the overwhelming majority of people who claim to have it have never been clinically diagnosed. Most of them have digestive issues because of their lifestyle and eating habits, not celiac. When you eat the kind of crap so many eat, you’re bound to fart a lot, and more.
If you don’t have celiac, there is nothing inherently wrong with gluten.
Nephew has it. Clinically diagnosed. Its real. Runs in a lot of Irish and Italians.
Yeah, it does. It requires an endoscopy to get 100% confirmation. My mother had it, a neighbor's girl has it, both clinically diagnosed.
I have a super lefty SIL who is sure she has it, has to have Gluten Free, etc. Ate so much Kale a few years back, she cannot ever eat it again, it put her in the Hospital. Then I watch her shove absolute garbage down her pie hole and she thinks it's the bread that did it.
If you have Celiac, ANY gluten will set you off quick. Not sorta, not I can have just a little, it's all or nothing. If you can eat half a piece of bread and aren't crapping your pants inside of a half hour, you don't have Celiacs.
