I know, I KNOW, we are omnivores (you, me, maybe not our llm friends, but most of us)... but that doesn't quite line up with biological necessity.

I would argue we are facilitative omnivores, but obligate carnivores. We can eat plants for efficiency (famines and whatnot), but they are not necessary for life. Meat, however, is necessary - at the very least we would have b vitamin deficiencies without meat, and babies wouldn't develop into healthy humans without it.

People will argue, and i love you all for it, that maybe this applies historically but in the modern food environment we can engineer our way out of this obligation - sure, that's true, but when speaking of our species appropriate and native diet - we would still be obligate carnivores

What I am stating is that B12 can be obtained from other sources besides meat and that such sources - one of which is eggs - could be accessed by early humans.

The inclusion of meat in the diet of our ancestors has been demonstrated to be linked with the rapid increase of brain volume; meat is calorie and nutritionally dense, there is no denial of that.

But it is not something to overlook that humans descend from tree dwellers, which were most probably exclusive herbivores. For many more millions of years than meat, as a food stuff, has been part of the diet.

Thus, stating that humans are obligate carnivores makes no sense. Humans evolved to be omnivores, from herbivores.

    Right. I think we kept some of the ability to detoxify some plants from the herbivorous apes we descended from, but then we spent millions of years scavenging (probably eating a lot of brains as we could smash skulls of lion kills open with a rock), then hunting, following migratory grass eaters

    Plants became emergency food. We're not as good at detoxifying them as a gorilla is

    Hunter gatherers universally (outside the wet tropics where fruit is plentiful year around) eat meat when meat is available, and only use plants when the hunt fails

    We classify animals as obligate carnivores when we see them in wild eating only meat. When we have found humans in the wild they eat only meat. If you study pre-agriculture bones you find they had a practically all meat diet.

    Before agricultural and sedentary life became dominant, it is a well known fact humans were hunter-gatherers, with hunting providing the larger portion of their calories. Herbivores were plentiful and large; a single kill provided a good amount of food for a group for some time. Such a life style forced the following of herds.

    Detoxify strikes me as an odd choice word. It's been the quest, and a very successful one, for farmers since the taming of the first crops to selectively improve them to obtain better and safer results at each season. There is an honorable mention with cassava, which is inherently toxic due to the presence of cyanide in the tuber, but can nonetheless be safely consumed through careful preparation.

    Cooking, through the original use of fire, enabled the species to make better use of all food. Cooking facilitates digestion and the absorbtion of nutrients. Nearly all of the food consumed on the planet is cooked; unless someone is eating their food completely raw, the concer with toxicity is very low and, in my understanding, irrelevant for what we have been discussing.
