Microbiome determines mood! When it's happy it wants you to eat ice cream. When it's sad it wants you to eat ice cream.

So you're saying there's a chance it wants me to eat ice cream?


The two million unique bacterial genes found in each human microbiome can make the 23,000 genes in our cells seem paltry, almost negligible, by comparison. ‘‘It has enormous implications for the sense of self,’’ Tom Insel, the director of the National Institute of Mental Health, told me. ‘‘We are, at least from the standpoint of DNA, more microbial than human. That’s a phenomenal insight and one that we have to take seriously when we think about human development.’’

This blows my mind.

Who are we? Is a human just a giant ecosystem for a trillion bacteria?
