The issue is that it is circular. If someone hasn't been diagnosed with celiac, they're told that they should not give up gluten. But the reason they have not been diagnosed may be that their doctor may be behind the times or incompetent, or that they are asymptomatic, or that the tests give high numbers of false negatives, or they are non-celiac gluten intolerant.
So 4 of 133 people had abnormally high gliadin abs and no symptoms? That sounds pretty reasonable. The PSA screen for prostate cancer is discouraged for younger, asymptomatic men for this reason. Lots of men had positive PSA tests and had to undergo invasive and expensive tests and treatments for no reason. A gliadin ab blood test should be among the tools used to diagnose patients of Celiac disease, but it is certainly not true that anyone who doesn't have Celiac symptoms should get tested and be forced to undergo a massive lifestyle change for no reason. No one should give up precious, precious beer if they don't have to.
So far I doubt it. I underwent a massive, massive diet change to a very extreme diet. We'll see how it goes. I haven't had diarrhea today!I think you have a problem with digestion of fat. Perhaps you can handle certain types better than others. Maybe you need to limit your overall fat intake.
