“Although most of us conduct our lives as omnivores, in that we eat flesh as well as vegetables and fruits, human beings have characteristics of herbivores, not carnivores.”
William C Roberts, M.D.
Cardiologists, with over 1500 publications in the peer reviewed medical journal. There are two components to this question; behavioural and biological.
If we take a moment to look into the animal kingdom, we can compare the physiological comparison. The human body is more closely related to primates (monkeys, chimpanzees, gorillas) than to any other animal on the planet. There is an estimated 99.4 per cent shared DNA between humans and primates.
Look at your hands, don’t they look similar to that of a gorilla, rather than that of a tiger with claws. The claws of the carnivore are used to rip apart the flesh of their pray.
Our teeth are flat like those of a gorilla, whereas the carnivore teeth are very sharp and have a distinctive K9 for chewing into animal flesh.
The herbivores teeth are flat, for grinding. Without these sharp claws and teeth, it would be impossible for the carnivore to hunt and feast on their prey.
Then there’s the digestive tract. The carnivores digestive tract is only 3 times it’s body length, whereas the herbivores in a whopping 12 times it’s body length.
The carnivore’s stomach also contains more acid than the stomach of the herbivore so that it can breakdown the flesh eaten.
The human liver has a low tolerance for uric acid; a byproduct of animal protein. The liver of the carnivorous tiger however, contains uricase, which is an enzyme used to break down uric acid.
This enzyme gives the tiger’s liver around 15 times the capability to break down animal protein that the human liver can.
Carnivores have a very high level concentration of acid in their stomach juices which helps to efficiently break down high concentration of protein, whereas humans stomach acid is much less concentrated.
Further to this, the human digestive tract is very long, around 9 metres long (approx 12 times the length of our torsos), whereas the digestive tract of carnivores is around 3 times the length of it’ torso; designed to quickly rid the acidic waste of animal protein.
The long intestinal tract of humans is just not designed to process large amounts of animal protein. Due to the length of the human intestines, the animal protein consumed cannot be processed quick enough through the digestive tract, that it can begin to rot. This can produce unhealthy bacteria growth and toxicity in the body.
The biggest strongest animal on the planet are herbivores. Apes, rhinoceros, hippopotamus and elephants.
There is a condition called Atherosclerosis. It is a condition that causes plaques of cholesterol to coat our vessels and can occlude blood flow causing heart attacks and strokes. “Atherosclerosis affects only herbivores. Dogs, cats, tiers and lions can be saturated with fat and cholesterol and atherosclerosis do not develop.” William C Roberts, M.D.
Carnivores and omnivores can eat all the animal products they like and will never develop atherosclerosis. Cholesterol in our diet is only present in animal products and humans do not need this.
From birth, most humans were raised as omnivores. From the first few years of birth, we are fed animal products in the form of baby food from a jar, so it is no wonder that us humans have grown up believing that consuming animal products is a normal an essential component of human life.
Looking at the physical make up of the jaw of the carnivore VS the herbivore, we can see that humans are more closely related to plant-based animals, therefore, humans are designed to be plant-based to avoid illness and to thrive.
