Yes, that review also cites 94 references and (the core of the reference is 3 tables that reviews existing literature anyway) and was published in MDPI's peer-reviewed open access journal Nutrients. Every other publication I listed was also peer-reviewed and can be read in full and is also full of citations. That's sort of the point of having scientific literature.

But sure, since he's "highly respected" this Dr Greger sounds like a stand-up guy with no axe to grind, let's see: https://en.wikipedia.org/wiki/Michael_Greger as a "professional speaker on public health issues, particularly the benefits of a whole-food, plant-based diet and the harms of eating animal products" and the vegan publisher of the web site you cite as well, you don't say.

But, he's an academic? Let's see what he's published (lots of peer reviewed work on nutrition and metabolism I'd expect): https://www.researchgate.net/profile/Michael_Greger

Oh hmm, maybe I have the wrong guy, it's just a couple animal welfare papers.

Hey, up to you where you want to get your scientific information (same goes w/ the WHO, which I agree isn't a pop science source - it's a ... public health agency/policy advisory body). I'll just read the peer-reviewed literature, thanks.
