I turned vegan after watching Game Changers: https://gamechangersmovie.com/the-film/where-to-watch/ https://gamechangersmovie.com/the-film/where-to-watch/ It was made by a guy who trains soldiers in deadly unarmed combat. He got injured and read that a vegan diet could speed up recovery. Instead of trying to convince with ethical concerns, it gave me plenty of sound logical reasons to eat vegan. The reason for me to eat organic meat was B12, but 39% of the people eating meat still have a B12 deficiency. 80% of farmland is used for animal husbandry, the size of Africa! We can feed way more than seven billion, if we farm more efficient. And when the strongest man in the world got there being vegan, i can skip animal products too.

> 80% of farmland is used for animal husbandry and how much of that is marginal land that can't be used to grow crops?

  Most of that 80% is used to grow crops, that are then fed to animals.

Where do you get your b12 then? It’s excreted by bacteria and cleaned off in processing. Then, in most functional foods, put back in place as cyanocobalamin. But that produces cyanide when your liver processes it. So again, where do you get your b12? Is it cyanocobalamin?

  > But that produces cyanide when your liver processes it. Very small amounts. I don't see much evidence that people should be scared of cyanocabalamin (smokers potentially excluded), but of course if it's something you're worried about there are supplements that are based on adenosylcobalamin and methylcolbalamin instead. I'm sure some people will disagree with me on this, but I would not personally recommend going vegan without taking a B12 supplement. Yes, there are fortified foods now, but I sort of feel like it's safer. Honestly, it's something that non-vegans should at least kind of think about as well, since... a non-trivial number of non-vegans are also B12 deficient. But the more straightforward way to sort this stuff out is to just get a blood test and then ask a doctor.
