I’m a dietitian and I totally disagree with this black and white approach while I wholeheartedly agree with fruit is an excellent snack and had the same issue with my DC school without warning (new head teacher had lost load of weight on some fad diet and had become totally evangelical about diet and nutrition in the extreme - even shaming kids in assembly by scrutinizing the bins for wrappers and checking packed lunches!).
My active child does a lot of sport, wakes early and did over an hour of running around and playing football with chums before school started). They had breakfast at 7 am ish but school lunches were at 12.30ish.
My child also hated eating warm bruised fruit so would not eat any of the fruit I tried to give them! I get it… no one enjoys slimy bananas or a bashed around plum after that’s been knocked around while walking to school - hence refused to eat! This resulted in him being extra hungry at pick up especially if he hadn’t like the school meal that day 🤦♀️
I felt strongly that snacks like the plain popcorn or rich tea biscuit, hot cross bun, breadsticks/ rice cakes, while weren’t amazing, were better than no snack at all!
when in infants, they had fruit provided by school which was great but it doesn’t travel well! Even grapes in a pot can be difficult for some children, like mine, who has lots of sensory issues.
Many kids are fussy in primary school (which is often just a stage) and very particular which can be a challenge.
I know they mean well, but as a parent, I knew my child was better off eating something rather than nothing especially as they are growing rapidly and expending a lot of energy.
I think they should put their energy into educating the kids to make good, balanced food choices and educate the parents too. This approach of encouraging them with some examples of healthier snacks including fruit is better in the long run.
some kids don’t like any fruit - which means they don’t eat a snack! Some don’t even need snacks if they had a late, decent breakfast, some kids skip breakfast for a host of reasons and a piece of fruit may not be enough… individual approach is better as the parents are responsible for the majority of the food intake and wellbeing.
I could go on… ! Sorry to waffle!
Short answer is, you are right and I would raise it with school.
fortunately, it was year 6 so we could leave a few months later and his secondary school’s catering and snack choices are the polar opposite but that’s a different story 😩
