If you’re not trolling, I think you need to learn more about the difference between carbs, other nutrients, and indigestible material. “Carbs” does not mean “anything you can digest” (which seems to be how you’re using it).

For all animals, of course ensuring that you have enough energy to function is a primary concern, but health studies in modern contexts always assumes that the supply of carbs is a solved problem (modern foods generally have far more carbs than most people need), but at the expense of reducing other nutrients.
