Because there's a fairly large swath of American popular culture that has sprung up to "nuh uh" every perceived standard or best understanding. "Avoid saturated fat" "nuh uh our ancestors were alpha males that ate nothing but raw meat and black coffee, we must have evolved for that diet!" People fall for it because people like eating meat and there's enough bad studies to cherry pick to support that position. It's not unlike a family member of mine who falls for every woo scam because whatever is being peddled from drum circles to breathwork makes them feel good so of course they spend $3k to become a "professional sound bath instructor". American culture is increasingly distrusting experts and worshipping flim flam artists because they make a compelling podcast or YouTube video.
