Of course kids should eat healthy, but a web search seem to disprove that higher calories snacks have a negative effect. Papers I found are https://www.sciencedirect.com/science/article/abs/pii/0195666390900519 and https://www.sciencedirect.com/science/article/abs/pii/S003193840200882X
School goes as far as preventing the kids to eat their snack if it’s not a fruit or a vegetable which I find excessive, as many healthy snacks exist today that still contain some (more) carbs (the two papers are even about candies…)
Are there some studies out there for what would be an optimal snack (both health and performance wise)?
I would imagine it’s less about the possibility of other healthy choices and more about not putting more things on the overworked teacher’s plates (so to speak). Which is the faster way to tell if kids have a healthy snack: seeing a row of kids eating fruit, or going to each one, looking at the snack’s wrapper, figure out if the ingredients sound healthy enough, hope that you’re not going to have to get into an argument with the kid because their parent found a couple of research papers on the internet, then move to the next one.
