Apparently a lot. And it doesn’t matter whether it’s real food from McDonald’s or carrots put into a McDonald’s wrapper. They’re pretty significantly preferred, as a rule.
I know my kids adore McDonald’s food. They don’t get it nearly as often as they’d like – once a month or so, unless we’re on vacation and eating out a lot and eating fast anyhow.
It’s an interesting perspective on just how much kids are impacted by advertising at a very young age. I don’t know if this would show up strongly with my son, as we can easily pass by a McDonald’s and he won’t care. My daughter on the other hand, I can see this working on her.
Of course, as my daughter has learned, just because she loves their food doesn’t mean she gets it very often. We keep that stuff pretty limited.
