Our planet is home to carnivores, herbivores and omnivores.
As you probably know, herbivores eat plants (including grains, leaves, seeds) and carnivores eat meat in order to survive. Omnivores are animals that eat both plant and meat to survive.
Humans regard themselves as omnivores. But are they?
This data should clues us on:
A. Oral Cavity
Their mouth opens wide in relation to the size of their head. This helps them snatch, kill and dismember prey easily — using their mouths.
Their tongues are rough. Carnivores can sweat only from their tongues, and not from their bodies. Their tongues protrude outwards to enable them to drink water easily.
Their jaw moves up and down and not side to side because they don’t chew their food — they simply swallow it.
When their jaw closes, their blade-shaped cheek molars slide past each other to give a motion that efficiently rips meat off bone.
Omnivore mouths are designed more for attack because omnivores can survive on meat and fruits/vegetables.
Omnivores cannot digest some of the substances contained in grains.
Their lips are fleshy, their mouth opening is small and they have a muscular tongue.
The lips aid in the movement of food into the mouth and, assist in chewing. Their tongues are smooth.
Herbivores perspire their skin pores and don’t have to pant like carnivores to cool their bodies.
Their jaw moves up and down and side to side because they must chew on their food — they cannot just swallow it.
Their teeth are strong and flat molars that can efficiently grind leaves. Their canine teeth are either small or non-existent.
Like the herbivores, humans have muscular lips and a small mouth opening. Their tongue is muscular and agile and very essential for eating.
The human jaw can move up and down and side to side, just like a herbivore.
Unlike omnivores, our mouths are engineered to socialize (and not attack).
A carnivore’s teeth are discontinuous and spaced because otherwise carnivores would get their mouth full of messy and fleshy debris.
Their incisors are short, pointed and can easily grasp and shred their prey.
Their canines are elongated and dagger-like for piercing, tearing, mauling and killing prey.
Their molars are flattened and have jagged edges which makes them work like blades.
Omnivore mouths are built like a carnivore’s.
Omnivore mammals have all varieties teeth(canines, incisors, premolars and molars)
Herbivore teeth are grouped closely so that their incisors can bite efficiently.
Their upper and lower molars work as platforms for crushing and grinding.
Human teeth sit closely and are just like a herbivore’s.
The incisors are flat and spade-like and meant to peel, snip or bite into soft materials.
The canines are flat, blunt and small. The premolars and molars are square and flat and can be used for crushing, grinding, etc. and converting non-coarse foods into pulp.
Carnivore saliva does not contain digestive enzymes.
Carnivores do not chew food because enzymes cannot be liberated in the mouth. If enzymes from the flesh are liberated in the mouth, it will damage the carnivore’s oral cavity.
Carnivores don’t have to mix their food in saliva; they bite huge chunks and swallow them whole.
It is like carnivore saliva, which does not contain digestive enzymes.
Herbivores chew their food methodically by pushing it back and forth into grinding teeth using their tongue and cheek muscles.
This is necessary to disrupt plant cell walls so that digestible intracellular contents are released mixed with their saliva.
Herbivore saliva contains enzymes that break down food molecules while the food is still in the mouth.Human saliva contains enzymes that help in the digestion of starch.
Human esophagus is narrow and only small, soft balls of thoroughly chewed food can pass through it. Saliva softens the food some more.
Eating quickly or swallowing food can choke humans. saliva plays an important part in the chewing process.
D. Small Intestine
Carnivore stomachs are simple and single-chambered.
Their stomach volume is 60-70% of the total capacity of the digestive system.
Their small intestines (where food molecules are absorbed) are short & 3-6 times their body length. This is because meat is easier to digest when compared to veggies. Veggies contain cellulose which is harder to digest.
The carnivore stomach can also efficiently secrete hydrochloric acid. They keep their gastric pH down around 1-2 even with food in their tummy. This is required breakdown proteins and to kill dangerous bacteria found in decaying flesh.
Carnivore’s gut structure + some gastrointestinal adaptations to enable plant consumption
Herbivore stomachs are longer and in some cases, very elaborate. Herbivorous animals that consume plants containing loads of cellulose have stomachs that “ferment” food to obtain nutrients.
Herbivorous animals that eat soft vegetation (not too much cellulose) have a simple stomach, and a long small intestine.
The small intestine of plant-eating animals is very long (more than 10 times their body length) to facilitate adequate time and space for absorption of the nutrients.
Human stomach is single-chambered and moderately acidic.
The stomach volume is about 21-27% of the total capacity of the digestive system.
The stomach mixes, stores and liquefies food and regulates its entry into the small intestine. The human small intestine is 10-11 times the body length (head to spine). Therefore, human stomachs are built just like an herbivore’s.
E. Large Intestine (Colon)
The carnivore’s large intestine or colon is simple and very short. It is only required to absorb salt and water and therefore functions as a reservoir.
It is short and non-pouched.
Carnivore-like colon that is adapted to handle plant consumption
The herbivore’s colon is a sophisticated organ that aids water and electrolyte absorption, vitamin production and absorption, and fermentation of fibrous plant materials.
The colons are wider than the small intestine and are long.
The human colon has a pouched structure just like the herbivores.
Human colon is responsible for water and electrolyte absorption and vitamin production and absorption.
Sharp claws. Engineered to tear flesh and cause grievous harm.
Omnivores can have claws (bears), or hands (like primates) for holding food.
Flattened nails or blunt hooves.
Weak nails that are incapable of tearing flesh.
Carnivore livers are large and they secrete 10 times the uric acid as compared to human livers. That’s because high volumes of uric acid are required to break down meat into amino acids.
Omnivore livers also secrete a large amount of uric acid to help digest flesh.
Herbivore livers are smaller and secrete 1/10th the uric acid secreted by carnivores. That’s because it doesn’t take much uric acid to digest plants, grains, seeds, nuts, etc.
Human livers are built just like herbivore livers.
Carnivores love the smell of blood and flesh.
They are like carnivores. They have an inborn instinct to kill animals.
Herbivores avoid dead animals.
Most humans hate the sight and smell of blood and decaying flesh
So what does this data tell you?
It tells you that we possess the gastrointestinal tract structure, instinct, organs and physical characteristics of a pure herbivore.
There is no other conclusion other than that we are designed for a 100% plant-food diet. If we are eating meat and relishing it, now is the time to stop and go back to what we were intended for.
Go vegan now!
Or go to hell.
