That's my theory, too. I let her taste crumbs of chocolatey stuff, and if there's cake at a party, she gets some. She regularly bakes stuff at Oma's house (and often brings it home to share - yum!) and she's not lacking for treats. The trick is to teach kids that junk food is okay for a treat, but it's not a food group and it can't take the place of healthy foods. That means having it available, in small quantities, and trusting them to know some limits - or setting some, if they're too young for that. I think part of the reason I like my junk food so much is that it was such a luxury when I was growing up - we just couldn't afford it. I didn't start to gain weight until my disposable income reached the point where a chocolate bar was a near-daily snack. If more had been available at home, it might not have been a problem.
