If you aren’t lactose intolerant, this is something I just recently learned: chew your food very well. I know, it sounds like a given, but our stomachs and intestines don’t have teeth or any effective way to grind our food down into tiny pieces. To some extent I have caused myself needless suffering by underchewing my food.

Weird way to think about it “drink your food, chew your drinks” let your saliva work on the stuff too.
