I can't fully agree with avoiding the topic altogether. Yes, people need to be careful, but building real knowledge in complex subjects like health generally requires engaging continuously (same as in Computer science) with research and studies (and learning to evaluate them critically) AND gathering people' opinions and perspectives (very important, after all, the experience of an MD grows over time because of reports of side-effects from your own patient, which is close), rather than shutting out discussion entirely, even for yourself who is already an MD. Also not everyone had the opportunity or desire to study medicine formally but still want a chance to be able to understand it in greater depth, and one great way to learn is to read a ton.

We can also relate that some drugs (albeit most are illegal but whatever, it doesn't invalidate them) from recreational to bodybuilding drugs are practically only massively "studied" by the bro-science community and many topic about harm reduction and so-on stems from there, enormous amount of people have started getting interested into health, supplements... due to reading about it randomly from people.

Although, in practice, you are partially right, it also does damage because many people will just take it as face value and just don't have enough expertise yet to do a proper reasoning around some takes and might not check if it's factual.
