Because regular people read this bullshit uncritically, journalists write more pop articles based on that, which makes more people read it... and suddenly your mother starts calling you about pills you should/should not be taking, and your SO starts to insist on random dietary changes.

Even if this stuff doesn't cause huge hurt, it definitely causes annoyance.
