Is it just me or are vegans just the anti vaxers of the dietary World?

There is zero evidence to say that veganism is sustainable long term for the body. Any diet that requires supplementation is not species appropriate or sustainable. That said there is zero evidence of any diet being sustainable long term because they can't lock clones up in labs for their entire lives for various obvious reasons.
I happen to know several ex vegans quite well who've between 6 and 14 years on that lifestyle under their belts. They've switched from vegan, due to various health issues like losing their menstrual cycle and organ failure. They're now on Carnivore and doing much better health wise with most if not all seeing their health conditions go into remission. Health generally across the board is a lot better.
