What makes it frustrating is that sugar shouldn't be the end of the world; treats have their place.

But the quanity of cheap sugary snack items available in any American grocery -- for example, let's say a Chewy Bar. Is it bad by itself? Well, maybe not the worst alone. But overall, it's an insignificant amount of food. It's nothing + sugar. There isn't ever really a reason to eat one.

Extended from that. Soda, pizza, burgers: these things aren't a meal by any stretch of the imagination. More akin to a lite-drug than a form of nutrition. But so often this could be considered "lunch" instead of "once a friday night" thing -- optimally after a healthy breakfast and lunch.

The problem isn't exactly that sugar and junk food exists. The problem is that junky items are presented as a legitimate solution to "in case the students/staff/ are hungry," which could then become "in case I'm hungry." If your body and brain have been working and playing, pouring sugar on top of the exhaustion is a harmful practice.

Hell, drinking water and training your ability to wait out until you can find a sufficiently large healthy meal is good for adults. For kid's nutrition though, often out of one's hands, but if we water our gardens with trash don't be surprised when things don't grow correctly. American schools, businesses, communities... there needs to be much stricter nutrition protocols as to what can be presented as food.
