Chapter 1. Determining Our True Dietary Nature
Humans vs. Carnivores
The following is an incomplete list of the major differences between humans and carnivorous creatures.
• Walking: We have two hands and two feet, and we walk erect. All of the carnivores have four feet and perform their locomotion using all fours.
• Tails: Carnivores have tails.
• Tongues: Only the truly carnivorous animals have rasping (rough) tongues. All other creatures have smooth tongues.
• Claws: Our lack of claws makes ripping skin or tough flesh extremely difficult. We possess much weaker, flat fingernails instead.
• Opposable thumbs: Our opposable thumbs make us extremely well equipped to collect a meal of fruit in a matter of a few seconds. Most people find the process effortless. All we have to do is pick it. The claws of
allow them to catch their prey in a matter of seconds as well. We could no more catch and rip the skin or tough flesh of a deer or bear barehanded than a lion could pick mangos or bananas.
• Births: Humans usually have children one at a time. Carnivores typically give birth to litters.
• Colon formation: Our convoluted colons are quite different in design from the smooth colons of carnivorous animals.
• Intestinal length: Our intestinal tracts measure roughly times the
length of our torsos (about 30 feet). This allows for the slow absorption of sugars and other water-borne nutrients from fruit. In contrast, the digestive tract of a carnivore is only 3 times the length of its torso.
This is necessary to avoid rotting or decomposition of flesh inside the animal. The carnivore depends upon highly acidic secretions to facili-tate rapid digestion and absorption in its very short tube. Still, the putrefaction of proteins and the rancidity of fats is evident in their feces.
• Mammary glands: The multiple teats on the abdomens of carnivores do not coincide with the pair of mammary glands on the chest of humans.
• Sleep: Humans spend roughly two thirds of every 24-hour cycle actively awake. Carnivores typically sleep and rest from 18 to 20
hours per day and sometimes more.
• Microbial tolerance: Most carnivores can digest microbes that would be deadly for humans, such as those that cause botulism.
• Perspiration: Humans sweat from pores on their entire body.
Carnivores sweat from the tongues only.
The 80/10/10 Diet
• Vision: Our sense of vision responds to the full spectrum of color, making it possible to distinguish ripe from unripe fruit at a distance.
Meat eaters do not typically see in full color.
• Meal size: Fruit is in scale to our food requirements. It our hands.
A few pieces of fruit is enough to make a meal, leaving no waste.
Carnivores typically eat the entire animal when they kill it.
• Drinking: Should we need to drink water, we can suck it with our lips, but we cannot lap it up. Carnivores' tongues protrude outward so they can lap water when they need to drink.
• Placenta: We have a discoid-style placenta, whereas the carnivores have
• Vitamin C: Carnivores manufacture their own vitamin For us,
vitamin C is an essential nutrient that we must get from our food.
• Jaw movement: Our ability to grind our food is unique to plant eaters.
Meat eaters have no lateral movement in their jaws.
• Dental formula: Mammalogists use a system called the "dental formula" to describe the arrangement of teeth in each quadrant of the jaws of an animal's mouth. This refers to the number of incisors, canines, and molars in each of the four quadrants. Starting from the center and moving outward, our formula, and that of most anthropoids, is 2/1/5. The dental formula for carnivores is 3/l/5-to-8.
• Teeth: The molars of a carnivore are pointed and sharp. Ours are primarily flat, for mashing food. Our "canine" teeth bear no resemblance to true fangs. Nor do we have a mouth full of them, as a true carnivore does. I am reminded of one of Abraham Lincoln's favorite retorts: "If you counted a sheep's tail as a leg, how many legs would it have?"
Invariably, people would answer, "five." To which Lincoln would respond: "Only four.
the tail as a leg doesn't make it one."
• Tolerance for fat: We do not handle more than small quantities of fat well. Meat eaters thrive on a high-fat diet.
• SaUva and urine pH: All of the plant-eating creatures (including healthy humans) maintain alkaline saliva and urine most of the time.
The saliva and urine of the meat eating animals, however, is acidic.
• Diet pH: Carnivores thrive on a diet of acid-forming foods, whereas such a diet is deadly to humans, setting the stage for a wide variety of disease states. Our preferred foods are all alkaline-forming.
Determining Our True Dietary Nature
• Stomach acid pH: The
level of the hydrochloric acid that humans
produce in their stomachs generally ranges about 3 to 4 or higher but can go as low as 2.0. (0
most acidic, 7
The stomach acid of cats and other meat eaters can be in the range
and usually runs in the 2s. Because the pH scale is logarithmic, this means the stomach acid of a carnivore is at least
than that of a human and can be
or even 1,000 times stronger.
• Uricase: True carnivores secrete an enzyme called to metabolize
the uric acid in flesh. We secrete none and so must neutralize this strong acid with our alkaline minerals, primarily calcium. The resulting calcium urate crystals are one of the many pathogens of meat eating, in this case giving rise to or contributing to
arthritis, rheumatism, and bursitis.
• Digestive enzymes: Our digestive enzymes are geared to make for easy fruit digestion. We produce
known as salivary
to initiate the digestion of fruit. Meat-eating animals do not produce any ptyalin and have completely different digestive enzyme ratios.
metabolism: The glucose and fructose in fruits fuel our cells without straining our pancreas (unless we eat a high-fat diet). Meat eaters do not handle sugars well. They are prone to diabetes if they eat a diet that is predominated by fruit.
• Intestinal flora: Humans have different bacterial colonies (flora) living in their intestines than those found in
animals. The ones that
are similar, such as lactobacillus and e.
are found in different ratios
in the plant eaters' intestines as compared to those of the
• Liver size: Carnivores have proportionately larger livers in comparison to their body size than humans.
• Cleanliness: We are the most particular of all creatures about the cleanliness of our food. Carnivores are the least picky, and will eat dirt, bugs, organic debris, and other items along with their food.
• Natural appetite: Our mouths water at the sights and smells of the produce market. These are living foods, the source of our sustenance.
But the smell of animals usually puts us off. Meat eaters' mouths water at the sight of prey, and they react to the smell of animals as though they sense food.
How anyone could recommend a 'paleo' diet after reading this is a mystery.
