Its important to follow evidence based medicine rather than eminence based medicine. Respected organizations get it wrong sometimes, in fact being wrong is an important part of the research process.

Cutting edge research is research into areas that are not well studied. Future studies will the confirm or refute those findings. It’s only when enough research has been done, and the field is no longer cutting edge, that we can really be certain of the results.

The gold standard for evidence are meta analyses which look at the totality of research on the topic. They will look at every study and trial done and draw conclusions on that basis. If one of those says something, its probably true and you should trust it.

I should remind you that the paper that started the modern anti-vaccine movement was published in The Lancet, one of the most respected British medical journals. A fraudstsr, con artist, and then licenced doctor tried to cash in on the reputation of his employer and status. The result is the persistent lie that vaccines cause autism that we are still dealing with today over 25 years later.

You have to learn levels of evidence and analyse information on a case by case basis. Eminence counts for little. There are no shortcuts.
