Science Conclusively Verifies Humans Are Frugivores
This article could get VERY LENGTHY, VERY quickly, but I'll keep it short and cite all the sources. 

 William Clifford Roberts, M.D. is an American physician specializing in cardiac pathology.

Given the area of absorptive intestinal mucosa to body size ratio, what we are evolutionarily equipped to adequately 1. digest  2. absorb 3. utilize and 4. eliminate is primarily #fruit as an ideal food source.  

"In populations where many of our deadliest diseases are practically unknown, such as rural China and rural Africa, they’re eating huge amounts of whole plant foods, up to a 100 grams of fiber a day or more, which is what it’s estimated our Paleolithic ancestors were getting based on dietary analyses of modern-day primitive hunter-gatherer tribes and by analyzing coprolites, human fossilized feces. In other words, #paleo poop.

These most intimate of ancient human artifacts were often ignored or discarded during many previous archaeological excavations, but careful study of materials painstakingly recovered from human paleofeces says a lot about what ancient human dietary practices were like, given their incredibly high content of fiber, undigested plant remains. Such study strongly suggests that for over 99% of our existence as a distinct species, our gastrointestinal tract has been exposed to the selective pressures exerted by a fiber-filled diet of whole plant foods. So, for millions of years before the alleged "first stone tools and evidence of butchering," our ancestors were eating plants. But what kind of plants?

One way you can tell if animals are natural folivores or #frugivores is to map the area of absorptive mucosa in their gut ( area that is capable of adequately absorbing and utilizing nutrients of our food) versus their functional body size. (refer to image above)  Folivores are those meant to eat mostly foliage—leaves, while frugivores are better designed to eat fruit. The faunivores, another name for carnivores, eat the fauna.

If you chart animals this way, they fall along distinctive lines. So, where do humans land? (refer to image above) Here’s our functional body size, and here’s our absorptive area. So, while eating our greens is important, it appears the natural dietary status of the human species is primarily that of a fruit-eater." - Dr Michael Greger- physician and lead nutritionist at

It must be made crystal clear that what people (tribes, cultures, ancestors) eat and ATE is ENTIRELY INDEPENDENT of what we're designed (evolved, equipped ideally) to eat. For example, if tribes migrate(d) to a certain locale or are forced out of an ideal way of life due to cataclysm etc, (such as leaving fruit bearing tropical climates due to sea level rise in ancient prehistory as seen from underwater megalithic stone temples from around the world) then that doesnt mean their way of life currently is the most ideal that the body thrives on, such as "paleo" diet or atkins diet or other FAD BULLSHIT low carb, high fat diets that are EXTREMELY HARMFUL AS CITED CONCLUSIVELY.

"Atkins Diet: Trouble Keeping It Up," discusses a case report of a man who went on a low carb diet, lost his ability to have an erection, and nearly lost his life. That was just one person, though. Researchers at Harvard recently looked at ONE HUNDRED THOUSAND PEOPLE and concluded that low carb diets were “
associated with higher all-cause mortality, higher cardiovascular disease mortality, and higher cancer mortality. 

Conclusion: "A low-carbohydrate diet based on animal sources was associated with higher all-cause mortality in both men and women, whereas a vegetable-based low-carbohydrate diet was associated with lower all-cause and cardiovascular disease mortality rates." 

High carb, low fat LIFESTYLES are associated with the LOWEST risk and actually REVERSE all cause mortality rates. 

excerpt via Jon Stearns: 

Do humans have a species specific diet?

Every species in nature has a diet that nature has designed for them.
We have the omnivore species, herbivore species, frugivore species, and the carnivore species. Before we analyze the human species, let's take a look at what kind of diets the other species eat and thrive on.
Polar bears 
Humans & primates 
When it comes to anatomy and physiology, what others species in nature to we resemble the most out of these categories ?
Why don't all species eat the same? Why are there even categories?
The digestive tract is designed to eat specific foods depending on what species you belong to. Nature really does make things simple for us. Humans seem to complicate the simplicity, and reality that we are no different then other species in nature. Humans are the most confused species when it comes to the food they eat! 
Humans teeth are designed for a diet of fruits, nuts, seeds, sweet vegetables & herbs. 
If we were to compare are anatomy to other species in nature what species do we resemble the most? I would say the primates with common sense.

Why do humans complicate things when it comes to the food they consume? We know not to give are pets certain foods, but we don't know how to feed ourselves in order to be healthy!

Look at how closely we resemble the primates that are deigned as biological frugivores. 
Human teeth are not designed for tearing flesh as in the lion, wolf or dog, but rather compare closely with other fruit-eating animals. Human teeth correspond almost identically to the chimpanzees and other frugivores. The complete absence of spaces between human teeth characterizes us as the archetype of frugivore. The "canine" teeth of humans are short, stout, and slightly triangular. They are less pronounced and developed than the orangutan's, who rarely kills and eats raw flesh in its natural environment. Human canines in no way resemble the long, round, slender canines of the true carnivore. Human teeth are not curved or sharp like the wolves or tigers, nor are they wide and flat like the grass and grain-eating species. Human teeth are actually like the fruit-eating monkeys, and the human mouth is best suited for eating succulent fruits and vegetables. It would be extremely difficult, if not impossible, for humans to eat raw flesh without the aid of fork and knife. To term our incisor teeth "fangs" or even to liken them as such is outrageous.
It's quite obvious to me that humans do in fact have a species specific diet like other species in nature, and it's 99% identical to the chimpanzee fruigivore species.
Fruigivore species is designed to eat at least 95% of there food consumption from fruits!

When we look at the facts and eveidence based on the diet are Anatomy is most compatible with, then you would think we would be more aware of what we should eat! We are so confused it's scary!

If we keep things simple maybe we can get far in healing are bodies simple going back to the foods we are designed to eat instead of following a ridiculous structure of eating a variety of chemistry to meet a specific macro or nutrient quantity.

We go on crono-meter to see if we are meeting a specific daily nutrient content? For what? It's as simple as understanding that every species in nature has a diet designed for them and it's 100% raw and the Homo sapiens are not a special exception to this!

Do we really think that cooking our food and eating other species is healthy? Has intellectualism and unconsciousness brain washed us this bad? Stop wasting your time with crono-meter or meeting a certain macro ratio, and just eat the foods your designed for.
Your designed for fruit so get over trying to justify getting proper nutrition from other places! 
Why are we so confused about fruit? Why are the so called "nutritional experts" demonising the very food humans are designed for? I'm so tired of hearing about how getting to much fructose is harmful for you, or it can cause faty liver! Maybe high fructose corn syrup can, but not fresh,whole, ripe and organic fruit of the tree grown in nature!!! Fruit sugar is life and energy for the cells in the human body.
I know that these so called nutritional experts are stuck on vegetable thinking. ("The green movement")
The facts are humans are not designed to eat veggies. The cellulose fibers in the veggies are not even digestible in the humans digestive tract.
There is a good reason we created juice extractors, and there is a good reason why so many people struggle with digesting vegetables. 
An herbivore is an organism that feed exclusively or mainly on plants. Herbivores typically have adaptations towards a specialization of eating and digesting plant matter. This could include but is neither limited to nor has to have flatter teeth to grind plant matter, long intestines, gut microbiome to digest cellulose and other hard-to-digest parts of plants.
Do we even come close to resembling horses,cows,elephants, or a deer?
Cows have multiple stomachs for a good reason, because there designed to brake down and digest plant matter, humans aren't.

If someone even tries to claim that veggies are better for us then fruits there stuck on none empirical evidence, and have invested in unconscious "Intellectualism" that holds no water, and should be ignored, rather then praised as health experts or "pioneers" in the health movement.

Saying fruit has too much sugar is like saying water is to wet! If we don't use are common sense, and get back to nature, and eat the food for our natural design, everything will come into balance in its proper time. Fruits are good for you, they are designed for you, and you are a fruigivore species designed for a species specific diet like every other species in nature.
Fruit is the easiest food to digest, which should right there, tip us off that we are biologically designed to eat it. Just because we are able to digest other foods, does not make us fit for their consumption. Omnivores are designed to eat everything. Humans can eat meat, but they are not designed to, which means they are not true carnivores or omnivores.
It's quite Interesting that the very food thats designed for humans, is also the very food that heals them, and detoxify them better then any other foods source.
You can make excuses all day, and try and justify that eating fruit based diets are not healthy for you, but at the end of the day your concepts are just built on theories, and not Built on facts. Imagine you’re the only person on Earth, there is no infrastructure, there are no restaurants, only you and the wilderness. Soon you’ll undoubtably get hungry. What are you going to eat? There are animals running around everywhere, so you could kill one and cook it over a fire. But time is of the essence and you need something to eat now, not later. Besides, the act of killing an unarmed animal and tearing its flesh apart doesn’t exactly sound too appealing.

Fructose is the highest energetic form of a monosaccharide or simple sugar. Neurons (nerve cells) especially attract fructose molecules. Fructose enters the cell through diffusion molecules. Fructose enters a cell through diffusion instead of via active transport, which its counterpart glucose uses. Diffusion saves the energy for the body and cells.
Any activity requires energy, including the activity of transporting nutrients across cell walls.

Most nutrients also require a helper or carrier to assist in this movement through the cell wall into the cell. As ATP (adenosine triphosphate) is a cells stored energy, it is used in active transport (the assisted transportation of nutrients across cell membrane walls). Glucose needs insulin to a certain degree as a "utilization hormone" for this active transport. Fructose, on the other hand, requires no ATP or insulin and is simply pulled or absorbed through the cell wall by diffusion.

For diabetics, fructose is perfect, especially if they remove complex sugars from their diets.complex sugars create excessive glucose levels in the blood which then creates more insulin demands.

Raw fruits and vegetables are always your best sources of simple sugars. This is One reason why your blood become stronger and more energetic on these foods. Foods high in protein and low in sugar's, or foods high in complex sugars, rob your body a vital energy, creates acidosis and elevate blood sugars. Simple sugars also aid alkalization of the tissues, which is vital for tissue regeneration and vitality. As stated, fructose is the highest electrical sugar in nature and is superb your brain and nerve regeneration.
Fruits are good for you, they're designed for you, and they will not hurt you in anyway. There is no food,supplements, or superfood on this planet that's more superior than fresh ripe organic fruits.

The evidence is clear that humans are frugivores. If we don't except this fact we could never move on to simplicity with what foods were supposed to eat. The diets of every other species in nature is very simple and not complex. The more simple we keep things the cleaner our bodies will get, and the more healing we will attain from it. 
Eat simple, eat what's design for your species, and ignore the theories , and intellectual concepts that holds no water or facts."

"Food combining is a science unto itself. Many people don’t necessarily pay attention to how they combine their food. But believe it or not, how we eat is just as important, if not more important, as what we eat.

When we look at our dinner plate, we rarely think about how the food will be broken down or how the body will utilize the food as energy and repair sources. Many times people defeat the purpose of eating “healthy” if they are wrongly combining the foods they eat. Poor food combination can have serious, dangerous and long-lasting negative affects on your GI tract as well as your body ecology. Poor food combination goes beyond uncomfortable bloating and gas. These are only the initial symptoms to a larger phenomena occurring.

There are two most commonly recognized patterns of dysbiosis associated with poor food combining, putrefaction and fermentation. Dysbiosis refers to a condition with micro-bacterial imbalances on or within the body. Dysbiosis is mostly associated with the digestive tract. A number of inflammatory diseases within the bowel or involving skin and connective tissue have been reported in association with dysbiosis.

The further from fruit we get, the higher the risk and rate of mortality, and THAT is survival of "the fittest" (least risk for self induced mortality, most in tune, or SYMBIOTIC with our environment)........
