The thing that I find quite interesting about these threads (in hindsight) is how in describing veganism etc, there appears to be a lot of use of terms like
"overwhelming evidence, indisputably, "the" science clearly states" etc ( I should do some thematic analysis
), when a lot of what is being posted is numerous lay press articles written based on the same four journal articles, and of those mostly informed by one (Poore and Nemeck, 2018) I genuinely think that to non-scientists (who presumably instantly look at the reference list) giving the very real impression of a vast body of work.
Four articles is nobody's "overwhelming evidence" or indeed "substantial body of work".
For interest, I have referenced the four journal articles I think inform most of the press articles that have been posted on this thread:
