Most of us here who are gluten-sensitive, and who test negative to the celiac blood tests, are at least as sensitive to gluten as the "average" celiac, and some of us are much more sensitive than the "average" celiac, (that is, we have a lower reaction threshold - it takes less gluten to cause a reaction.) It is somewhat rare to find celiacs who react at the 20 ppm gluten level, that's why 20 ppm was adopted as the maximum allowable limit for a "gluten-free" label. (Actually, most celiacs can tolerate up to 50 ppm of gluten, according to Dr. Fasano's research that was published a few years ago.) However, note that some celiacs are also much more sensitive than the "average" celiac, (as demonstrated below).Lassie wrote:Question: I still don't know if you are gluten sensitive if you have to be as strict as you do with celiac????
Note that in that study, (and in the chart parameters), "MC" stands for "microchallenge", (not microscopic colitis).Conclusions: The ingestion of contaminating gluten should be kept lower than 50 mg/d in the treatment of CD.

Note a major flaw in that study, however:
So what do you think they did with that subject's data? Why they threw it out, of course, so that's why the research showed that anything below 50 mg of gluten per day is "safe". (IOW, that level is safe, except for the unlucky individuals who are more sensitive than "average".) If they had included that particular individual's data, the study would have shown that even 10 mg/d was not safe, for 8% of celiacs, (1 out of 13), so they would have had to start over with their research project, and test for a lower reactive range.One patient challenged with 10 mg gluten/d showed typical signs of relapse (vomiting, diarrhea, and abdominal distension) after 6–8 wk of microchallenge but refused to repeat the t1 evaluation.
If Dr. Fasano had really been interested in establishing a gluten threshold that was safe for all celiacs, he would have scrapped that data, and started over, with new subjects, (and preferably a much larger cohort - 13 people in each group is a mighty low number to be basing such critical statistics on, IMO). He got what he wanted - a cheap research report, but I'm not sure that it's worth much more than the paper it was printed on, unfortunately.
Of course, I have no random, double-blind study data to back up this observation, but IMO, there is probably a higher percentage of people with MC, who are sensitive to gluten at thresholds below 20 ppm, than there are celiacs in that category, FWIW.
