Remember when militant vegans weren't racist, homophobic, sexist, classist, and/or ableist dickbags?
Just a few excerpts to show that not only does meat not rot in our stomachs, but other things do.
We crush food in the mouth, where amylase (an enzyme) breaks down some of the starches. In the stomach, pepsin (another enzyme) breaks down proteins, and strong hydrochloric acid (pH 1.5-3, average of 2…this is why it stings when you vomit) further dissolves everything. The resulting acidic slurry is called ‘chyme’—and right away we can see that the “meat rots in your stomach” theory is baloney. Nothing ‘rots’ in a vat of pH 2 hydrochloric acid and pepsin.
But apparently the pH of our stomach acid is 4-5?
Eventually our pyloric valve opens, and our stomach releases the chyme, bit by bit, into our small intestine—where a collection of salts and enzymes goes to work. Bile emulsifies fats and helps neutralize stomach acid; lipase breaks down fats; trypsin and chymotrypsin break down proteins; and enzymes like amylase, maltase, sucrase, and (in the lactose-tolerant) lactase break down starches and some sugars. Meanwhile, the surface of the small intestine absorbs anything that our enzymes have broken down into sufficiently small components—usually individual amino acids, simple sugars, and free fatty acids.
Finally our ileocecal valve opens, and our small intestine releases what’s left into our large intestine—which is a giant bacterial colony, containing literally trillions of bacteria! And the reason we have a bacterial colony in our colon is because our own enzymes can’t break down everything we eat. So our gut bacteria go to work and digest some of the remainder, sometimes producing waste products that we can absorb. The remaining indigestible plant matter (“fiber”), dead gut bacteria, and other waste emerge as feces.
It turns out that pepsin, trypsin, chymotrypsin, and our other proteases do a fine job of breaking down meat protein, and bile salts and lipase do a fine job of breaking down animal fat. In other words, meat is digested by enzymes produced by our own bodies. The primary reason we need our gut bacteria is to digest the sugars, starches, and fiber—found in grains, beans, and vegetables—that our digestive enzymes can’t break down.
Now we’ll move on to actual herbivores:
Most of the edible part of a plant is cellulose, a polysaccharide (i.e. a very long chain of sugars) that is very difficult to break down. In fact, no digestive enzyme, in any animal, is capable of breaking down cellulose! So the only way that any animal can fully digest plants is for its gut bacteria to break down cellulose, and its intestines absorb the waste products.
Ruminants, including cattle, bison, deer, antelope, goats, and other red meat, have a special “extra stomach” called the rumen. They chew and swallow grass and leaves into the rumen, ferment it some, barf it back up again, chew it some more (called “chewing the cud”), and swallow it again, where it is digested a second time. Hindgut fermenters, like horses, have an extra-long gut. And rabbits run their food through twice: they eat their own poop in order to get more food value out of the plant matter they eat.
And here’s why humans aren’t herbivores:
Humans, in contrast, don’t have gut bacteria that can digest cellulose. That is why we can’t eat grass at all, why there is so little caloric value for us in vegetables, and why we call cellulose “insoluble fiber”: it comes straight out the back end.
This fact alone proves that humans, while omnivores, are primarily carnivorous: we have a limited ability to digest some plant matter (starches and disaccharides) in order to get through bad times, but we cannot extract meaningful amounts of energy from the cellulose that forms the majority of edible plant matter, as true herbivores can. We can only eat fruits, nuts, tubers, and seeds (which we call ‘grains’ and ‘beans’)—and seeds are only edible to us after laborious grinding, soaking, and cooking, because unlike the birds and rodents adapted to eat them, they’re poisonous to humans in their natural state.
There you have it, folks.
Humans aren’t herbivores. Your ‘facts’ are false. You’ve made entire tables to try to fool us omnivores. Little did you know that we’re actually smarter than that.
And all it took was a simple search. The link provided even has numerous sources.
Now if you don’t mind, I’m going to go eat some dead animals and digest them happily.
