In addition to the mom with a job has no time to cook good food for the family theory, there is also the fact that crappy food is cheaper - just check the price of white bread vs 100% whole wheat bread. Fake cheese is cheaper than real cheese. Fresh veggies are more expensive than canned. For some people, it’s a real struggle to eat fresh, healthy food on a budget. (Yes, I know - grow a garden. Thank God I can, but not everyone has the ability to do that!)

True as that may be, I very much doubt that kids are getting fat from eating white bread and canned veggies. More likely, the parents abuse McDonald’s and Twinkies.
