There are every kind of vegan. No broad generalities cover everybody. That's how.

There are vegans and then there are non-vegans. Being a vegan and eating something non-vegan make you a non-vegan. Cows milk is not vegan.

...says one vegan. I ask others, I get a different answer.

This is the typical "No True Scotsman" argument. Look it up.

Legumes, vegetables, and fruit?

Legumes to me are healthy, but i can't see them as 100% peak human food, you have to soak them for hours and many people get bloated, then there are also certain amounts of anti-nutrients.

I’m expecting truly engineered food to be a breakthrough over the next 100 years. Imagine people being able to eat something akin to a chocolate bar that has all the nutrients one would expect from a full meal. Protein shakes are close to this, but they are still just a mix of vegetables mostly (and the ones I drink have high sodium.) I know everyone is expecting lab grown meat, and I’m sure there will be some of that, but I think we aren’t thinking about the possibilities and it could be people in 300 years eat textures and flavors far better than anything we can imagine, while being as healthy as physically possible.

Well, regardless of the topic at hand (the point about brain-size shrinking when eating plants certainly sounds interesting), already the infographics are full of obvious typos ("Domesticsted", "Larg prey") which suggests shoddy editing at least. While that made me chuckle a bit in the context of "brain size" it also leads me to not giving to much credence to the quality of the rest of the text (which I cannot really…

I think the answer is pretty simple: we should eat varied and follow the seasons. That many get pretty sick by going into ketosis shows how unhealthy we are. A healthy human can switch between a diet with lots of carbohydrates and one with few without problems. I'd posit that more than 99% of humans cannot switch between fat burning and glucose burning without getting sick because of withdrawal symptoms.

This topic always becomes an ideological football in public discussions. Nevertheless... The article completely misstates the purpose and findings of the paper, which isn't being helped by the authors here. The position taken in the paper is much less extreme. To summarize, they're staking out a position that middle paleolithic foraging groups were primarily carnivorous, but still had some level of dietary plant cons…

> completely misstates the purpose and findings...primarily carnivorous, but still had some level of dietary plant consumption.

That's exactly what the article says, so not sure why you're saying it completely misstates the purpose and findings.

Link to the actual study: https://onlinelibrary.wiley.com/doi/full/10.1002/ajpa.24247

There seem to be some rather dubious assumptions there, notably that hunting is a more efficient way of acquiring nutrition than gathering. I'm not a specialist in the field, but my understanding was the opposite. And sentences such as "[...] baboons [...] devote almost all their daylight hours to feeding [...] while adult Ache and Hadza men spend only a third of the day in food acquisition, preparation, and feeding"…

For prehistoric nomads hunting would definitely be a more reliable source of food. Think of winters, when there's little to gather but you can still hunt a mammoth or some other large prey. This way, you take advantage of the muscle/fat the animal built while eating stuff you can't eat.

So, I could see prehistoric nomads being mostly carnivores for a whole season. Which would also leave enough evidence on their remains.

But I agree that the authors seem to have a bias/motive (entrepreneurial and academic) to overstress the importance of eating meat, perhaps cherry-picking on the available evidence.

In 2019, age 30, I ate only red meat (and a little fish) for about 8 months. It was by far the peak of my physical condition. Better sleep, stronger workouts, no mid-day grogginess. Blood test results were as best as one could hope for, apart for the debatable "high cholesterol". Unfortunately a couple of trips abroad (damn Italy) and I got back to a more standard diet. Have put on 15kg since. I've been longing to re…

And I know of two people (bitcoin evangelists, lol) who had explosive diarrhea or an impacted bowel on a meat only diet, and had to be hospitalized. Whereas my athletic performance on a vegan diet has never been better as well. What to make of this? The body can adapt quite nicely to many foodstuffs as long as you do proper research on what foods to eat so you get all the nutrients you need. Not eating fruit and vege…

>The body can adapt quite nicely to many foodstuffs

In a perfect world yes, but we live in a world where (at least in the West) pretty much everyone is addicted to sugar. A healthy body could switch between burning fat and burning glucose but I have yet to meet anyone who can do this without having been eating keto for a while. It's harder but possible as a vegan and I would recommend it to anyone. Just once and the body is better at switching back and forth.

That's a bummer about the meat quality in Israel. I'm guessing it's just super expensive???

The meat I can buy at any big US supermarket can only be found at mid-high end butcher shops, and costs about 3 times more.

The meat you can buy in any big supermarket in the US is awful quality that much of the world bans from importing. It's no surprise that meat is more expensive elsewhere.

I would say 95,000 years is plenty of time to begin to develop adaptations in diet. If as a species our survival was still threatened by starvation for another 100k years we might see more adaptation towards meatless, but that seems unlikely.

It depends how much of an advantage a certain diet brought from a procreative standpoint. If milk drinkers were the only group who could obtain the necessary amount of calories for bearing offspring and sustained existence, then the adaptation would happy much more quickly. Perhaps even as quick as several generations.

It's not quite as binary as that. Milk tolerance ranges from poison to healthy and everything in between.
