Ok, well here is another question. Is it possible to develop an allergy to one of the strains? I'm wondering if since I took the kefir while I was battling food poisoning, if my immune system could have mistaken one of the good bacterial strains (in kefir) for a bad strain (from the veggies) and as a result, goes into defense mode every time I consume it. Maybe it lasted so long because my immune system was trying to eliminate all of that strain. Does that sound at all plausible or am I reaching here?
