I just can’t see how - unless children are already eating similar food at home - they are going to just start happily eating more healthily at school. Homes where they learn about food and eating habits - I don’t think schools can turn around a poor diet. I grew up in the UK - I know what the standard British diet is like, I’m reminded every time I go home and see the endless shelves of processed food and teeny tiny bags of salad in Tescos, and the Greggs / chicken shops on every street corner.
I live in France, two kids who’ve gone through the system plus I work in a school. For a start, French kids eat veg and salad as a matter of course, at home, from babyhood. It’s not rocket science, it’s just salad with every meal, reasonable portions including boring old veg and seeing adults eat the same.
School meals are exactly the same as the food that most of them will be have grown up eating. Bowl of salad to start, protein plus veg/carb main, cheese, then a yoghurt or fruit for dessert.
very importantly, there is no other choice. At my school there is the cantine serving a 4-course lunch - or nothing. The idea of going onto a school menu and choosing what my kids will be offered as @Ketryne describes just boggles my brain - there is no way any school in France would think that appropriate, private or not. They all get the same and they are expected to eat, or at least try, it. It gets less strict as they get older, secondary schools are self serve. But I’ve seen the head chef at our school walking around and commenting on the lack of veg a kid has chosen - he sees it as part of his job to nag them.
The cantine does not sell sandwiches or muffins or sausage rolls or cans or chocolate or anything other than a sit-down meal.
There is no tuck shop.
There are no vending machines.
Packed lunches are only allowed with a doctor’s note confirming allergies.
Outside school, there are no chicken shops, no chip shops, no Greggs. Food is generally expensive - even the cheapest takeaways tend to be €10 plus, compared to school lunch at €4.75.
So that whole food environment contributes hugely to why French children will (more or less happily) sit down to a ‘proper’ lunch.
The last lunch I had at school was:
Self-serve salad starter - I think it was fennel/cabbage in vinaigrette, plus green salad. There’s usually at least 4 options.
Main - roast chicken leg, pommes purée and carrots / turnip mix. Usual a choice of two mains, one carb, 1-2 veg.
Dairy - small piece of cheese and bread, or a yoghurt.
Dessert - piece of vanilla cake, or fruit, I think I had a fromage blanc with some red fruit on top.
we get frites maybe three times a year 🤷♀️. Pizza ditto (and it’s rubbish). Burgers maybe once a year during a ‘theme’ week.
