Holy crap! I come back and there's like three new pages!
I'll jump in here, if ya don't mind
I, too, respectfully disagree

What you call "rough", I call "fiber". I also acknowledged that there are anti-nutrients in plant foods that we need to be aware of. But even people who take oxalic acid seriously acknowledge that foods should not be chosen in terms of its content because its presence is extremely low, except for in a very few plants. We're talking a really high content being 1% (as in spinach). Only those who have kidney issues should really be careful. I personally avoid eating spinach raw. But the fact is plant foods are more complex in chemical composition period. This is a good thing. Medicinal herbs require this complexity. There are also some very dangerous chemicals in plants, like as in pointsiettas and poison ivy, but that doesn't mean we should avoid all plants altogether. I don't have any specific health issues that I'm dealing with, so maybe we're on different pages.

Fiber
= Rough. No two ways about it. Fiber has been known to literally scrape against the intestinal wall and rupture cells, which release a mucousal defense mechanism. This mucous interferes with nutrient absorption in the short run, and in the long run,
supposedly it causes permanent scarring, which will forever inhibit nutrient absorption. But I haven't confirmed the latter, except maybe by the fact that scientists don't know how many times the intestinal cells can recycle themselves, which could be suggesting that they can only take so much scraping from fiber.
The plant toxins in modern neolithic vegetables were bred to be low- it is absurd to imply that we evolved to digest these foods, as for millions of years any plants that didn't have a high toxin content were eaten to extinction by the bugs- what survived to reproduce back in the day were highly poisonous plants. I thought the goal of paleolithic eating was to match as closely as possible what we evolved to eat, not consuming specially bred neolithic 1% oxalate content spinach. Even if it ends up being not that harmful (which I doubt anything with fiber and a significant carb content is healthy in the long term), one question: WHY? Why consume such rough hard-to-digest foods when you can get your nutrients elsewhere? Addiction to variety? A dogmatic fear of missing some "important" chemical not found in meats? (Even though we didn't evolve to derive full nutrition from plants). If you want medicinal value, drink tea, it's more easily absorbed and utilized anyways.
I suspect your research sources date to the neolithic or proto-neolithic (40,000 years to present, for a concise time period). As humans became very successful hunters, we overhunted our game, and started to grow in population size and density, which in turn required the increasing dependence on plant foods to sustain our population. The domestication process took from 40,000-10,000 years ago, and then 10,000 to the modern day is agricultural (obviously, but just to reiterate). Any research on these time periods will of course demonstrate the use of significant and increasing plant food consumption, as domestication and agriculture were well under way. What does not follow is to deduce from these time periods that plants are healthy, or even necessary, for human beings, as 40,000 years is hardly enough time to develop into
truly omnivorous creatures. Sure, we opportunistically took what plant foods we
could digest (which wasn't much) if we found them, but this number was so small that plants' impact on our nutrition was insignificant.

But let's look at our closest primate ancestors. Their diet is primarly based on plant foods. We're 97% genetically related. So even if humankind primarily ate meat as you're saying, our biologies have evolved for millions of years to be suited to a primarily vegetarian diet. Along comes hunting, and for hundreds of thousands of years, a tiny percentage of our evolutionary history, some cultures ate meat primarily. To me, that is as lacking as a diet consisting of only grain or only veggies. Only a true omnivore diet reflects the full diversity of eating habits from time immemorial. Anything that deviates from that to me is a limitation.

STOP RIGHT THERE! We have diverged from our "closest primate ancestors" millions of years ago- plenty of time to evolve away from a mostly vegetarian diet. Chimpanzees and apes aren't even our ancestors- we
share a common ancestor, but we both diverged separate ways millions of years back, thus what they eat is irrelevant to what we should eat. 97% may sound like a lot in common, and in the broadest sense it is, but when it comes to nit-picky things like what we are primarily designed to eat, it is all the difference. Simplified: We began our divergence into carnivory by scavenging the dead carcasses of carnivores' prey- the hominids cracked open their bones and skulls with rock 'tools' to get to the brains and bone marrow- these highly nutrient dense foods allowed us to develop more intelligence, which allowed us to create even better tools, which in turn allowed us to actually begin hunting animals ourselves, so even before we were hunters, we were scavengers, incorporating increasing amounts of animal foods into our diets, until we developed into almost 100% hunters. We didn't just decide to make a spear one day and start eating meat- we evolved an intelligent hunter's brain over time from originally scavenging.

But as I said, I'm not even sure this scenario is even true. From my understanding the paleo people were hunter-gatherers , where women collected plant foods, while men hunted. Their diet reflected both. To go back to Rk900, the traditional Swiss diet and the Masai diet, as Price speaks about, are examples of non-veggie eating societies, but their diets consist primarily of raw dairy, which is not even paleolithic. So obviously people can survive without too many veggies, but although their faces are well-formed, perhaps they might have been even healthier in other ways had they also had more veggies. Asian cultures, which are some of the healthiest people in the world, eat hardly any meat or dairy, with some fish and lots of veggies.

Yeah, like I said before, the only thing that matters is that the various nutrients themselves are present (vit. A,D, minerals, proteins, etc.)- but meat and animal foods are the richest, most complete, most easily digested, and most nutritionally dense sources of these nutrients- tell me, if you went back past 40,000 years, would you be able to find your special fermented grains, sweet potatoes, and domesticated cow's milk? I doubt we evolved eating any of these foods (plant foods, as we both know milk is neolithic). Maybe some individuals have begun to develop the necessary genetics the past ~10,000 years to digest these foods to an extent (particularly cow's milk), but probably 75% of the global population hasn't. Funny how the ONLY thing no human being is allergic to is fresh raw meat, organs, and fats- some may react to aged meat, but we didn't eat it aged in most cases, we ate it on the spot, and later cooked the rest around the campfire- aging takes weeks, not a day or two (spare Native American use of pemmican, which I don't know if it had significant amines or not) Any other food, and SOMEONE has a sensitivity or allergy to it- soybeans, cow's milk proteins, vegetable toxins, you name it.
With regards to the Asian cultures- what??? I was under the impression, from first hand journalist and foreign exchange student accounts, that Asians eat fatty beef, fish, and pork, and then just use stuff like rice as a sort of 'after meal' finisher. They don't even eat the rice if they are full by the end of their main course- the meat course. I'd give you one of the links to a great account about China on this, but I can't find it at the moment. It explained how the Chinese actually eat very high fat, high meat, diets, with small amounts of veggie foods, as opposed to our Americanized high carb version of "Chinese" take-out food centered on veggies and rice.

But I do think that there can be variations based on heritage. Someone with an allergy to rice would not have survived in Asian cultures. But someone with an allergy to milk would probably have been weeded out from the Masai a long time ago. So perhaps two people can enjoy two different diets and still thrive.

But nobody is allergic to fresh meats and animal fats-
nobody. Also, there is not a SINGLE essential nutrient that is not found in the flesh, organs, and fats of prey mammals. Any essential vitamin, mineral, whatever: you name it, is not needed from plant foods. Vitamin C for example can be obtained in significant quantities from liver, heart, and brains, and fresh rare meat bypasses the need for vitamin C anyways in terms of collagen production. Plants are just supplemental for medicinal qualities. Got a cold? Find some garlic (or leeks back in the paleo day). Insomnia? Try a relaxing herb like chamomile. Parasites? Try wormwood. But in terms of nutrition, plants are worthless and unnecessary, and are unhealthy in food-sized quantities. Even if they were eaten frequently (which I doubt they were), they did not have very much digestible nutrition to be derived from them- the plant foods back then were small, more indigestible, and poisonous in higher amounts, so I doubt they formed a significant part of paleolithic evolutionary biology.
We evolved primarily as hunting carnivores, and our recent little vacations into plant food consumption have not lasted long enough for us to evolve any necessity for plant foods. Any plant-based eating was either a result of starvation, or a product of the neolithic revolution.
