 Are humans carnivores, herbivores, omnivores? I guess most people would agree on the latter, but vegans would try to tell you that maybe we're frutarians, keto people would try to tell you maybe, or zero carbers would try to tell you we're obligate carnivores, but a hyper carnivore is an animal who obtains 70% or more of their calories from animal foods, and an obligate carnivore is an animal that needs to obtain their nutrients from animal foods, and humans fit both of those things. So to say humans are obligate carnivores is completely correct. Now, the problem with modern conventional wisdom, unnatural access to food and supplements, modern science, modern medicine, preventing certain diseases and nutritional deficiencies, and humans not being in optimal health in general, it's difficult to convince people that animal foods are necessary in the diet, but the best example is people go vegan, they immediately see B12 and iron deficiencies. That's one example. In the case of me, where I believe that fat-soluble vitamins A, E, and K, vitamin D3 from the sun, omega-3 fatty acids, EPA, and DHA are not only required for optimal health, they're the reason we actually evolved in the first place. So when we look at indigenous groups of people, they all consumed 65 to 75% of their calories, at least from animal foods, in order to be in good physical health. And this means that we were a hyper-carnivores. Now whether it's plains Indians consuming 80% plus of their calories from bison, the Eskimos and Inuits consuming entirely caribou, fish, whale blubber, arctic mammalian fat, maybe the swish in the Loschental Valley eating dairy and cheese and some meat, rye breads. Every group of people had this amount of calories from animal foods, 65 to 75%, and then they obtained 30 to 35% usually from plant foods, sometimes more, sometimes less. The reason some groups of people use plant foods was because they couldn't procure enough fat for their energy. And a human needs 70 to 80% of their calories from fat, depending on their lean body mass. I mean, bodybuilders might need less fat, but you cannot get energy at a certain point from protein. It needs to be from fiber carbohydrates. So what I'm getting at is we ate these plant foods out of necessity depending on the location, depending on the climate. If it was up to the humans, they would not have eaten any plant foods. The reason we started incorporating grains in the Neolithic Revolution, the reason Australian Aborigines consume dozens to hundreds of even thousands of different types of animal and plant foods, is because they need to survive. The reason humans would kill each other and cannibalize each other is because humans are like wild animals. They will eat what's out of necessity. And even deer or horses, I mean, there's an example of horses eating fish to survive. There's an example of deer picking brains out of nets. There are many, many gorillas will eat grubs. These animals, they prefer to eat animal foods if they're available because they're more nutrient dense. Those animals might have evolved as a primarily herbivorous digestive system and they have to sit in the field all day and eat 10 to 12 hours. But when animal foods come up for those animals, they will eat them. I'll try to link that stuff in the description for you guys. Going back to, you know, how we actually started eating meat and hunting. I mean, there's a great documentary called The Warrior chimpanzees and that'll open a lot of people up to, you know, humans procuring meat for survival. There's great examples of our scavenger past and how I personally believe our ability to procure brain tissue and marrow from animals was the reason we evolved because if you look at a lion or a tiger, the reason they're not as intelligent as us is because our tool usage and ability to hunt and maintain a low muscle mass in comparison to those animals as well as digestive system lets us use more of our brain for other things. You know, if you're a lion or a tiger, a lot of your brain is being used to control the muscles and which they have much more of than us. You know, I mean the case of a bear, for example, bears are hundreds of thousands times stronger than humans but we can kill a bear because we poke a stick into their heart, you know. There's definitely something interesting to know about brain size versus overall physical body mass and function in regards to what foods you're able to procure. That obtainment of marrow and brain tissue, whether we scared off other converse animals with fire or stools or sticks or yelling, whether we just maybe happen to come across a scavenger's carcass and the lion couldn't break the skull open, whatever it was, those foods are very calorically dense. They're very high in DHA, Omega 3 fatty acids and not only that, that probably is what started our craving for rotten food because those corpses would not have always been fresh. Another thing is that herbivores, you know, they not only have to eat all day, they have to migrate and move to places where plant life flourishes. Same with, or they have to live in a tropical climate. In the case of humans, we're able to settle and since we can get calories from animal foods in a climate where plants don't normally grow, we were able to live in those areas. And this also has a lot to do with our ability to fish, which is definitely way more advanced in regards to intelligence than a lot of the other aspects that we used to do. And this relates back to what I said earlier about different tribes and different groups of people consume. You know, maybe the Swiss and the Lusciano to Valley only had rye bread and cheese. When the Aborigines in Australia had thousands of different foods. You know, humans can survive on various diets in various areas as long as there's X amount of calories from animal foods. Now let's actually talk about the physical stomach of humans. Our stomach acid is lower than wolves, if not similar. It's between 1.5 and 3.5. And this, you know, relates back to our scavenger past. In regards to the stomach length and intestinal length, it's similar to wolves. Wolves have a slightly shorter intestine, but if we start comparing our intestinal length to rumenant animals, you know, rumenants have five to 10 times longer intestines. They have multiple stomachs. And in animals that have a similar like structure to our stomachs where they have a gallbladder and just large and small intestines without a rumen, like gorillas have a much larger, and forgive me if I'm not saying that's right, the sacrum, which is the pouch in the front of the large intestine. And that's initially where all the food, the digested food leaves the small intestine and it goes into the large intestine. That's much larger in gorillas and rumenant animals because that's where it ferments. I mean, if it's not fermenting in the rumen or the multiple stomachs of the other animals, you know, there's both front digesting and hindgut digesting herbivorous animals. But the point is that humans are none of those. And not only do we have vastly different digestive tracks, those animals can actually digest cellulose and they can ferment that fiber into volatile fatty acids, long chain triglycerides, medium chain triglycerides, and humans don't have the capability to convert those foods. We need to obtain that from actual animal foods. When a cow eats grass, it's literally turning that grass into fat. It sounds crazy that cows are technically in ketosis, but that's pretty much what it is. These volatile fatty acids from fermentation are about 70% of the rumenant animals supply, like their energy supply, just to live. Another interesting example for the digestive tract is that the food putrifies in our stomach. It rots. But in animal stomachs, the food ferments. That's the main difference. Where the food is rotting in our digestive system, we're extracting all the nutrients from it. In rumenant animals, they actually need to ferment the plant foods to extract more nutrition from them. And that's why we see animals eat their feces sometimes. If you guys haven't seen my rabbit video, uh, from carnivore to rabbit or something, definitely check that out. And the gallbladder function is also drastically different between us and herbivorous animals. And this whole digestive tract thing, it arrives between different herbivorous animals and it gets really complicated in regards to physiology. But it's safe to say that from any sort of digestive standpoint and I mean, especially when people go on the carnivore diet and they, you know, vegans have multiple very large bowel movements per day. And carnivores have, what they notice initially is their bowel movements are much smaller. The meat digest much slower because we're extracting more nutrients from it. Meat takes three to five days to digest where most plant foods are out of your body within hours or a day. Uh, there's definitely anecdotal evidence to be said too about the actual digestive tract. And uh, I mean, what, I mean, I can't really, like I don't really think I need to say, I mean, eat any of the points I've spoken about in this video from the foods our indigenous ancestors used to eat the very apparent nutrient differences and access to modern science alleviating a lot of problems to digestive tract, all of these things make it individually. It would have been enough to convince someone that humans need to consume animal foods, but if we start talking about the face, whole structure, canines, guys, human face evolved partially for speech as well. And it's, there's so much more to evolution that I don't really want to go too much into it because I'm not an anthropologist, but you know, just keeping my art tool usage, our ability to procure animal foods in unnatural ways compared to other animals, those are all things to consider. That's why I'm sitting here in my nice, well, not my house, but in a nice house, not in the woods, you know, shitting in the woods, you know, like there's a reason I am in a house and making videos for you guys, you know, and I'm not in the woods trying to procure nutrition. It's because of our intelligence and tool usage and things like that. I guess one more thing to tie in here is back to my last video on facial development, you know, our brain size started decreasing in the Neolithic Revolution. So, technically speaking, our peak intelligence level was before we started incorporating more grains and more plant foods into our diet. And I guess the more recent Indigenous groups like the Native Americans and the Australian Aborigines have much better eyesight, much better larger brain size, much better physical development for the most part. You know, just a couple generations on, and you know what, let's just, let's end this here. You know, there's plenty of resources you guys can look at from what's in price, nutrition, and physical degeneration for all of the stuff on the tribes, the Indigenous groups, and I will link studies on those in the comments. If you want to look into the digestive tracks, I'll link that in the comments as well. I mean, unnatural access to food and minor vegan nutrient deficiencies. I don't really think I need to explain that for you guys, but if you guys do want to know about the importance of high vitamin animal foods, I'll put some links to some of my videos in the description that explain those things. And the scavenging past, I'll try to put that in the description too. I'll see if I could find the articles I was reading in relation to that. But, you know, people commenting on my videos saying humans are frugivores and herbivores and stuff, that's just driving me crazy guys. Like, it really is. You know, comparing teeth of animals and things like that, and then just the contradictory stuff that, like, deer actually will eat bird brains out like, I don't want to elaborate on this too much. I think I've, as with all my videos, I've touched on a couple points, and then you guys can kind of go into more research. So, if you guys would like to support my channel, please just share the video. If you guys would like to reach out to me for consultation in regards to improving your diet or overall health, shoot me an email, frankate-tifanoagymail.com. Usually what my clients do is they send me their past diet, and we go over what foods we would like to change, you know, maybe we need to change water as well, physical activity, sun exposure, pretty much I change every aspect of people's lives and improve it, to my understanding. So, thank you guys for watching. If there are any other videos you would like to see or like place an emphasis on, please leave a comment and let me know what you guys would like me to talk about next.
