Last year, Karen slow cooked a large brisket for dinner we were all looking forward to having it for days afterwards as leftovers. Frodo, our Goldendoodle had other plans and I learned about diet because of those plans.
As we were eating in the dining room my eldest daughter spotted the fact that the brisket was no longer in the spot we had served it from…odd. We went to investigate and there, with a somewhat guilty look on his face, was our 4th child…licking his considerable chops after stripping off all of the fat from the brisket. The muscle was all intact mind you…Frodo is no dummy, he knows what is good for him, first you get the fat cause your master might catch you in the act and you want to make sure you get the good stuff first.
Now take a look at these diagrams and find out how similar you are to Frodo and then ask yourself why it is such a good idea to be eating all those grains, legumes and greenery in general? Btw did you know that if you eat only protein and no fat you will get something called rabbits disease?
Carnivore Digestive System
Compare the human digestive system to the herbivore digestive system and to the canine digestive system. Here is the unmistakable answer to whether humans are herbivore, carnivore, or omnivore.
It is remarkable how similar the human digestive system is to a dog’s!
A pure carnivore has a simple tube for an intestinal system. That tube has a bulge at the beginning of it that serves as a stomach. The tube then winds and twists inside the abdomen of the carnivore. It needs to – it is roughly 6 times longer than the animal is, when measured in a living animal.
Starting at the mouth, here is how a carnivore digestive system works:
Jaws and Teeth:
Carnivores have canine teeth, also called carnivore teeth. The adult canine teeth of a dog number 42. Canine teeth rip and tear the flesh of its prey, and the jaws chew up and down, rather than side to side. Many times the carnivore ‘wolfs’ his food nearly whole. Some carnivores can go several days before they need to hunt and feed again.
A dog’s stomach can hold about 2 quarts of contents (4 pints, or 8 cups). It secretes hydrochloric acid for digesting and breaking down the food into liquid ‘chyme.’
Once broken down into its constituent parts, the small intestine is where the nutrients get absorbed into the blood stream. Digestion and absorption of nutrients (fat and protein) is extremely efficient. Less than 4% of fat, and just trace amounts of protein make it beyond the small intestine into the large intestine.
Carnivores have NO enzymes for digesting cellulose, a complex carbohydrate and the main building block in plant cell walls. Obligate carnivores such as dogs cannot digest cellulose.
The cecum in a carnivore digestive system is a tiny useless appendage. You may recognize the word appendix, which is the ‘cecum’ in humans. In both humans and dogs, the cecum has no known use, though we figure it’s gotta be good for something.
The large intestine (colon) serves a single purpose – to reabsorb the water out of the waste material. Anything left over at the other end of the long tube passes out and turns into manure.
Thanks to the hydrochloric acid in the stomach, the entire intestinal tract is close to sterile, until the large intestine. A very large population of healthy bacteria resides in the colon. This natural gut flora participates in immune system function by competing with and helping to minimize the presence of dangerous bacteria. While the bacteria manufacture b-vitamins, biotin, vitamin K and folic acid, it is unclear whether these nutrients are bioavailable to the carnivore.
