You seed the gut with nutrients. having lots of fiber and a varied diet increases the number of species that an adult has which is between a couple hundred to a thousand or so. Our guts are generally dominated by a bunch of beneficial bacteria.

which for many is not the case for a variety of social economic or behavioral reasons. Add in with explosions of bacterial populations due to alcohol or sugar and you can see how we can change our gut biome drastically from week to week.

I’ve noticed I really need to keep alcohol and sugar consumption in check. Sometimes it seems like one drink is enough to kick off a gut ecosystem collapse, and other times my gut is more resistant to the effects. Definitely trying to increase fiber consumption significantly.
