People are always asking me about our biology, and if we, as humans, can live off of a plant based diet, looking at our ancestors and how we have survived throughout time as a species. I am here to tell you, you ABSOLUTELY can thrive on a vegan diet, because humans are natural plant eaters. That’s right, we are not natural omnivores! There are shocking differences in humans verses natural meat eaters that will surprise you and maybe think twice about what you have been made to believe.
According to Dr. T. Colin Campbell, professor Cornell University and author of The China Study, We only recently (historically speaking) began eating meat, and that human beings were well developed as a species long before meat was included in our diets. He states that,
“The birth of agriculture only started about 10,000 years ago at a time when it became considerably more convenient to herd animals. This is not nearly as long as the time [that] fashioned our basic biochemical functionality (at least tens of millions of years) and which functionality depends on the nutrient composition of plant-based foods.”
Dr. Neal Barnard, head of the Physician’s Committee for Responsible Medicine(PCRM), also attests that humans are natural herbivores,
“Early humans had diets very much like other great apes, which is to say a largely plant-based diet, drawing on foods we can pick with our hands. Research suggests that meat-eating probably began by scavenging–eating the leftovers that carnivores had left behind. However, our bodies have never adapted to it. To this day, meat-eaters have a higher incidence of heart disease, cancer, diabetes, and other problems.”
Let’s take a look at the physical differences between natural herbivores(like us) and natural carnivores;
Natural Meat Eaters:
• Razor sharp teeth and claws meant for tearing apart the flesh and breaking the bones of animals
• Wide mouth opening in comparison to head size, meant to capture live animals and eat them whole or nearly whole
• Acidic saliva meant for breaking down the tough meat and skin of living creatures
• No pores
• Straight, wide, short digestive tract meant for quick and efficient digestion of meat
• Stomach holds 60-70% of the capacity of the digestive system, and is single-chambered, meant for holding large amount of food for a long time
• Stomach secrets hydrochloric acid to protect the body from the dangers of fermenting meat
• Colon is simple, smooth and short, meant to absorb salt and water, and the muscle surrounds the wall to keep it a smooth cylinder shape.
Natural Plant Eaters:
• Flat, round teeth and nails
• Relatively small mouth in comparison to head size
• Saliva that is majorly alkaline
• Long, winding, puckering, narrow, digestive tract meant for digesting plants
• Stomach holds significantly less food, and begins to break it down immediately
• Stomach secrets much less and weaker acid, intending to break down more fibrous food
•Colon is advanced, puckered and long. Meant to absorb water, electrolytes, absorb and produce vitamins, and ferment fibrous plant materials.
If you look carefully at the anatomical and physiological features of natural plant eaters, you will see that they perfectly align with the features of humans. And the naturally carnivorous features align with animals like cats, foxes, bears, wolves, and other natural meat eaters. You have to think, if we have these specific traits, we must be meant to digest only plants. Digestion of meat in the body of a natural herbivore can be dangerous and in many cases, deadly. When meat gets stuck in our puckered, narrow intestines, it ferments there and can cause colon cancer. That’s why all natural meat eaters have smooth, straight intestines, so meat can quickly pass through them and not get stuck. We also lack the ability to break down meat in our stomach acid and saliva, this causes our body to work much harder than it should in digestion. This can cause problems like constipation, gas, cramps, acne, sluggishness, and studies have shown these issues can even lead to depression.
So, let’s try to live the way that nature intended for us to. Go veg!
