Hmmmmm. Maybe I should have read the original article article before I posted about it.
A few simple tests at Enterolab could have easily answered the most vital questions. The case bears all the earmarks of someone trying to selectively eliminate foods from the diet, instead of eliminating all possibilities, achieving remission, and then trying to selectively add foods back into the diet to test them, one at a time.
I had the same problem myself, for a year and a half. Eliminating certain foods doesn't always work. When you're just going in circles, you have to cut out everything known to cause problems for virtually anyone, and then work backwards, because as long as you continue to eat
anything to which you react, you will continue to react, no matter how many foods you are avoiding.
Dr. Briffa's suggestion that the problem might be due to a deficiency of gastric acid sounds plausible at first glance, but if that were the problem, the bloating wouldn't begin within 15 minutes - it takes longer than that for most foods to begin to rot. In fact, for such a fast response, this smacks of a mast cell response, because only an IgE-based response could occur that quickly.
