I’m vegan, but for animal welfare reasons, so this discussion is mostly academic for me. I follow this guy for suggestions on what food I should eat as a vegan, but I’ve noticed he has a lot to say about the risks of meat consumption and he seems to be qualified and have relatively straightforward motivations (I think he lost his mother to cancer or something and says he just wants to find the truth). Everyone is flawed and as you say science is still investigating a lot, and we can’t do double blind or placebo trials with much of this stuff. But I’d be curious what you think of the studies!
