As with other areas of education:
It’s not that what’s presented needs refinement, nor that customers/consumers/students need more assistance, it’s that WHEN SOMEONE DOESN’T CARE, NOTHING WILL HELP THEM.
Everybody knows a bag of chips and a soda makes for an unhealthy meal. Putting detailed data, running PSAs, and adding a frowny face won’t discourage someone who decides to make that lunch nonetheless.
At some point people make their own decisions and enjoy/suffer the consequences.
Its called freedom!
