I don't have kids but I was looking at the lunch menu for my town schools and every day listed some kind of fruit for dessert. No cake, cookies or any sweet desserts. As a child in the 60's and 70's I remember having a sweet dessert available most days. I found this menu online for a school from 1965 and this represents basically what lunch looked like in my time. Dessert was always my favorite, especially cake! Probably why I've always had a weight problem. ;-) Wish they had only served us fruit!
