Interesting. Well, I don't know how much capsaisin one has to eat to actually kill probiotics or negatively impact the gut in a similar way. Some say that this isn't a problem, I guess. I'm all for hot sauce, though. Years ago, I had an ulcer and before that, I had various stomach problems. Oddly enough, some of the crazy strongest (and caustic seeming) stuff was suggested for healing. Luckily I'm all for eating lots of that weird stuff.
