I think this assessment is unfair. The paper [1] is not from economists. The first author is an endocrinologist. The third author is a dermatologist. As for where the authors are from, I don't see why it would matter, as long as their methodology is sound.

However, this doesn't mean one should forget about the current consensus. This is just one paper, and it takes more than that to offset the current knowledge.
