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)?
What school would this be exactly? If it’s the primary school you’re currently sending your child to, and you disagree with their snack policy, do you have the right to present a challenge to the school board? Do other parents agree with your assessment and are willing to back you?
I have a theory that this school’s policy stems from a desire to limit the kids’ sugar intake during school hours, which makes it easier to manage behavior. If that’s the case, what “science” says about kid’s nutrition will only go so far. They’ll have their own research to rebut your complaint, and while I’m not trying to discourage you, you might find it to be an uphill battle to get them to modify their policy.
I don’t have an assessment, just a quick search, hence the question in the title, in the community asklemmy. I doubt they have actual data, just a policy they decided to push. With some concrete source (to nuance rather than refute their policy) I could at least ask questions, I’m not an expert
