I am not judging anybody, you can have whichever diet you want.

Nothing from a plant is dangerous according to any scientifically based diet.

We did not evolve with a carnivorous only diet, there are many studies about hunter gatherers and they have mostly a vegetarian diet with occasional meat.

Their gut microbiome is much more varied, and a varied ecosystem is a resilient ecosystem, therefore you are less vulnerable to pathogens bacteria.

You said: "nothing from a plant is dangerous according to any scientifically-based diet". But... plants contain oxalates, lectins, and phytates just for starters. Their seeds, roots, leaves, and stalks are all well defended. Only the fruit is "meant" to be eaten.

In fact, if you go out in the forest and just start randomly eating the plants you find there, then you will discover that 99% of all plants are inedible and will cause you severe distress or death if you persist in eating them.

Plants use chemicals to fend off predators, whereas animals will often fend off predators by running or fighting. So once an animal is dead its defenses have been overcome whereas once a plant has been killed all its chemical defenses are still intact. Interestingly, extraordinarily few animals are unsafe to eat -- less than 1%, which is the complete opposite of the percentage of plants that are edible.

Also, your remark that we did not evolve on a carnivorous diet is just wrong. In fact, homo erectus bones are almost always found together with the bones of mammoths, which they hunted and ate for something like one million years. Mammoths are just one of hundreds of species of mega fauna that ancient human hunted to extinction. Also, to this day there are indigenous human communities that live exclusively on meat (Inuit, Hazda, Sami, Maasai).

None of the groups you mention live (near-)exclusively on meat and that erectus hunted is well known. But hunted does not mean their diet was mainly meat-based. There is plenty of evidence from the teeth usage that our ancestors lived largely/mainly from consuming plants.

Okay, so apparently there is something going around in the vegan community about how humans evolved on plants. From what I can tell this is completely unsubstantiated. I don't deny that ancient humans ate some plant-based calories, probably fruit and berries, maybe a few tea leaves, but the vast, vast, VAST majority of their calories came from hunting -- remember that we're talking about the era before agriculture.

"The Hadza people eat no processed foods, are rarely exposed to antibiotics, and live seasonally, eating more meat in the dry season and a predominantly plant-based, high-fibre diet in the wet season. " "The staples of their diet include the baobab tree, high-fibre tuber roots, berries, fresh honey, and various meats from hunting. A common dish is a soup made from the baobab fruit, something renowned microbiologist Tim Spector sampled while living with them. Just one helping of this creamy mixture contains more fibre than the average Westerner gets in a day!" https://atlasbiomed.com/blog/the-hadza-people-what-can-a-hun...

Humans are omnivorous but it may change with circumstances. Polar bears are carnivorous while their counterparts in hotter climates are omnivorous. For people living in the cold climates there simply are few alternatives, other cultures may decide to eat a lot of meat because their way of living provides it.
