Given the enormous barrier to many people actually engaging meaningfully with the research (as this thread shows), what more can health authorities and individual doctors do than try to make recommendations based on their (ongoing) review of the evidence. Individual doctors can help translate key research to aid individual decision making but, at some point, people are going to need to just accept that the medical profession has actual expertise (and no one is trying to harm them!)
people put more trust in the dodgy takeaway they use at 3am (where, actually, scrutiny of the many processes and the provenance of the food may be merited!) than they do in well evidenced medical research.
we defer to peoples expertise and guidance in all sorts of ways. You don’t find anti civil engineering websites with lists of papers about the tensile strength of different materials and people shouting about how they need to make informed decisions before they cross a bridge. But there’s still been a lot of decision making gone into the design and construction of that bridge on behalf of the users.
