Food is such a tricky thing to understand.
We use it for social bonding as well as for altering, (distracting our emotional states).
Radically changing diet will also radically change our gut bacteria
It can take many weeks to settle
Also when we are consuming hundreds of different compounds it is very hard to know exactly what is causing inflammation etc..

For sure though there are people who seem to be thriving on all sorts of variations, very cool to see.

Have fun!
