Why cant fiber be broken down like other carbohydrates?
In: Biology
Humans are not herbivores. We did not evolve to produce the proper enzymes to break down cellulose directly, or have the gut bacteria and intestinal length needed to extract nutrients via hind gut fermentation. We are omnivores and evolved to eat a mix of vegetable matter and animal matter and as such only get certain things from both, but cannot get all we need from either.
