This is like the school regulations that say all kids have to get milk - even the lactose intolerant.
Or that all kids must take 2 fruits and veggies, even if they won’t eat it.
I teach & the amount of food thrown out is astoundingly depressing. In some cases whole lunches. I grew up eating pretty healthy ( what was then called health food or hippie food),but you can’t force that on kids. They simply DON’T like it. For the record I just bought two containers of Almond Rocca at Walgreens!!!!! I’m still a little twigs & nuts, but I love a good porkchop!
