DR. ANTHONY CHAFFEE: You're not supposed to have an overgrowth of a few [bacteria]. . . . in carnivores, people who only eat meat or animal products, [their microbiome] is actually quite a good profile, very, very diverse [bacteria].

Every single day that you eat, if you eat something different, you will have a different microbiome at the end of the day, because bacteria turnover is 20 minutes.  They rely on what we send down the pipe.  If you eat different things, you'll have a different biome everyday.  So whatever day you take that test, you'll have a different result.  You eat something, you know, curry chicken, this day, and you send it in you're going to have a different result. You have a vegetarian meal on that day, you're going to have a different result.  You're just eating steaks with no seasonings, you're going to have a different result.  The microbiome that they've tested in carnivores and in different sorts of people that only eat meat or animal products is actually quite a good profile, very, very diverse.  You have all these different sorts of . . . a lot of different bacteria.  You're not supposed to have an overgrowth of a few.  They seem to be the ones that are correlated with better health.  Now, is this because the bacteria themselves play a role in contributing to our health, or is it that what we're eating has a direct has a direct effect on our health and that also has a direct effect on what bacteria are going to be living in our gut?  I think he's probably is probably both.
