We've been warned about this since the at least the 80s maybe earlier. Then when it became more common (still not common I don't think) that the food pyramid is a sham it explained by school lunches when I was younger didn't usually seem all that balanced after I thought about it as an adult.

Couple that with cities that aren't designed to be walkable and its dangerous to bicycle and it just doesn't look good.

But hey, schools are probably going to get to serve chocolate, whole and 2% milk again due to winning arguments like "....fortifying nutrients of whole milk....Protein helps build and repair Santa’s muscles" and "...scientists, experts built the Titanic, and amateurs built the ark." So, that'll help, right?
