Children in key stage 1 get a piece of fresh fruit or veg a day- sometimes they get these tiny cucumbers which they love. Some kids at my school have milk at break time which parents choose them to have, it isn't free but i think it is pretty cheap. Also I think kids on free school meals get their milk paid for, but I'm not certain about that. I do know that we were stopped from giving them proper milk in cups due to health and safety, now they have those cartons of UHT and fewer of them drink it! Plus they love to inflate them and then burst them over the playground which in the heat is not good!
