Talking historical diets and excluding the modern bananas from the supermart, meat is not as difficult to digest as you might think. Aside from fruits and some other exceptions, plants are generally tough eating. Since they can't fight or run away, they protect themselves from being eaten by f.ex being poisonous or too tough to digest. Meat is generally easier on the stomach.
