The human stomach is in a constant, epic battle not to eat itself.
The inside of the stomach is full of acid to mash up your meals — but there are intricate forces at play to make sure that when stomach acid is done with your dinner, it doesn’t move on to eating your gut itself.

In the newest episode of our video series, Boddities, we explore how cheeseburgers, candy, and even salads can throw your gut into limbo.
