“How to Prevent Gut Inflammation”

If you think about it, there has to be a way for our good bacteria to signal to our immune system that they’re the good guys. There is. And that signal is butyrate. Researchers found that butyrate suppresses the inflammatory reaction and tells our immune system to stand down, so butyrate “may behave as a microbial signal to inform [our] immune system that the relative levels of [good] bacteria are within the desired range.” Butyrate calms the immune system down, saying in effect, “All’s well. You’ve got the good guys on board.” This ultimately renders the intestinal immune system hyporesponsive, (i.e., accommodating) to the beneficial bacteria. But, in the absence of the calming effect of butyrate, our immune system is back in full force, attacking the bacteria within our gut under the assumption that those are obviously not the good ones since butyrate levels are so low.
