Most of social media and most of real life have absolutely insane takes on health-related stuff. Ask someone at random about, say, keto, and you're pretty much guaranteed to get an opinion without any data behind it.

I think that part of this is because the effect sizes are so small. Grabbing some arbitrary sources, if you look at the average disability-adjusted life years (DALYs) lost to colorectal cancer as a result of red meat consumption in France[0] and put them into per-person terms, it averages out to a grand total of...less than 2 hours per person (presumably other causes also contribute). Meanwhile, for alcohol consumption and everything it causes, the average Australian is losing a little under 20 hours (and I assume most of HN lives in a country where this is similar).

These are pretty small numbers! I'm honestly not sure whether it's even worth worrying about them. No wonder people have trouble telling what's true in a field where many of the papers and most of the personal experience is just noise in the data.
