this is a lie.

we’re not rear gut fermenters, like gorillas.

what the vegan won’t tell you is that gorillas are amongst the animals that eat their own shit for b12.

this one’s also easy to debunk as 84% of vegans have a b12 deficiency.

“Greger is equally misinformed on B12 (cobalamin) synthesis since this occurs when cobalt is converted to B12 by gut bacteria. Yes B12 is synthesized by anaerobic bacteria, but those bacteria reside in the microflora of animals rather than in the soil. Remember too that in the natural world the distinction between an animal’s gut flora and the soil’s rhizosphere isn’t as distinct as it is in urban environments with waste treatment facilities. Animals, including humans, poop out different bacteria so gut microbes end up in soil, and soil microbes end up being consumed. Human guts actually contain the bacteria to synthesize B12 (10), however since we’re hindgut fermenters, we poop out this B12. Gorillas and chimps get their B12 by eating their own poop (coprophagia – see gorilla eating his own poop video here) With foregut fermenters like ruminants, the conversion happens in the four part stomach BEFORE the intestines, so the cobalamin is then absorbed in the intestines before being pooped out. As long as ruminants can get sufficient cobalt from their forages, they can make B12 in their guts which is then distributed to all their tissues. B12 is most bio-concentrated in the liver.”
