Very differently, I'd say. My mom didn't work when I was a kid, but wasn't very creative in the kitchen - we ate the same 10 dinners, on rotation, for the entire 18 years I was growing up. We had pizza every single Friday night. When I left the house, I'd never tried any seafood, asparagus, Brussels sprouts, kale, any sort of ethnic food (except for La Choy in a can), any tropical fruit, etc. We ate a fast foods a lot but I'd never been to a sit-down restaurant.
As an adult, we eat every differently. I cook a good deal of ethic food (Indian, Greek, Asian, etc.), and I don't repeat meals a lot (except for our very favorites). My kids rarely eat in a fast-food restaurant, and our normal eating out restaurant choices are Middle Eastern or sushi. I think that has a lot to do with the fact that we are better-off financially than I was as a child, and also that my husband is a much more adventurous eater. He's introduced me to a lot of new foods.
It's comforting, however, to go back to my mom's house sometimes because she's still cooking those same 10 meals on rotation for the most part. So it's nice to get a taste of my youth when I go there!
