I got a question, does antibiotics or natural antibacterial agents like say garlic do the same thing to us (the gut bacteria)?
Antibiotics effect gut bacteria yes. This post was about how compounds from those bacteria are taken up into the body more easily. That would not happen there.
I don't know anything about garlic to answer that part of the question, sorry.
Haha, I guess i kinda jump too much, I was thinking if alcohol helped the release of endotoxin or somehow enhanced killing of some gut flora to cause this.
This might also be another link to the alcohol related diarrhea, I don't really know, just some wild thoughts =]
Alcohol doesn't release the endotoxin, they are always there as the bacteria are always dividing and dying and breaking down. The alcohol makes the intestinal walls more permeable for the endotoxin so the body absorbs more of it.
I don't know anything of the mechanics behind alcohol and diarrhea ... I do know the effects first hand though :D
