I've been looking through some of my older cookbooks, and found these menu suggestions in a 1950 Betty Crocker cookbook. Click on the picture to read it better.
Just think, half the children back then weren't overweight like nowadays, either, even with all that meat, potatoes and bread. Of course most of them didn't have television; computers and video games hadn't been invented yet. They probably went outside and played tag and hide-and-seek. I imagine they had to help with the chores around the house and farm, too.
