I spent three days as a hunter-gatherer to see if it would improve my gut health

My microbiome is pretty healthy nowadays and, among the first hundred samples we tested as part of the MapMyGut project, I had the best gut diversity — our best overall measure of gut health, reflecting the number and richness of different species.

This was strikingly demonstrated when an undergrad student went on a McDonald's diet for 10 days and after just four days experienced a significant drop in the number of beneficial microbes.
