Fake rationality warriors on Wikipedia is a real thing. I have briefly made the mistake of participating in various nutrition articles before, and run into them. They seem to make extensive use of sources that don't support their claims, especially paywalled ones, with impressive sounding titles, that end up being glossy magazines with opinion pieces. There's a certain irony seeing science and rationalism defended in non-scientific and non-rational ways, and we should make more of an effort to call it out.
