There is, I understand. But the process of bacterial fermentation takes time, together with vast quantities of fibre, if you want enough yield to survive on. Ruminant animals are called “foregut” fermenters, because the rumen is the first of the four stomachs (next is the reticulum, then the omasum, and lastly the abomasum, or “true stomach”). The work of the fermentation takes place in the rumen.
There are other animals, such as chimpanzees and gorillas, that are “hind-gut” fermenters, in which the fermentation takes place in the small intestine. They lack the rumen, reticulum, and omasum. Ruminants have a comparatively short set of intestines, whereas the big bellies of gorillas and chimpanzees are filled with their small intestines, which is where their bacteria do the fermenting.
Human beings are not fermenters. We lack the rumen, reticulum, and omasum, and our intestines are quite short, when compared with those of our primate relatives. The change from a herbivorous to a carnivorous diet is what allowed our ancestors’ intestines to shrink, and yet still be able to absorb enough nutrition to feed our comparatively large brains. Any fermentation that still occurs in our intestines is purely incidental, at this point in our evolution.




not a good idea but once I had no other options so I know that now. apples always made me super hungry even if I would have been very satiated for quite a few more hours without it. carbs does weird things to me and sugars are the worst. in too big quantities, tiny is fine).
