There been some new work done on how our guts prevent bacteria from not attacking parts of our intestine - very interesting and possibly related to some immune issues

Interesting article. I have SIBO, which is small bacteria overgrowth, so I really did enjoy the article. I think that there are a lot of people who have a bacterial imbalance, in one way or another.
Thanks for sharing the link, Warmwaters!
Interesting article. It fits with what I read in the Discover magazine article on autism.
