DR. ANTHONY CHAFFEE: The microbiome that they've tested in carnivores and different sorts of people that only eat meat or animal products is actually quite a good profile. Very very diverse.

Every single day that you eat, if you eat something different you will have a different microbiome at the end of the day.  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 every day.  So whatever day you take that test you'll have a different result.  You eat something, you know curry chicken this day, you send it in, you're going to have a different result.  You have a vegetarian meal that day, you're going to have a different result.  You just eating steaks with no seasonings, you're going to have a different result.  The microbiome that they've tested in carnivores and 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 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 effect on our health and that also has a direct effect on what bacteria are going to be living in our gut?  I think it's probably both.
