News reports calling attention to the steady increase in the number of overweight adults have become an accepted part of our media landscape. Worse still, warnings continue that more and more young children, like the adults who care for them, are carrying too much weight. Unfortunately, this bad news about our growing obesity problem isn't just hype. Research confirms that children weigh more than they have in the past and, more ominously, that this weight, if carried into adulthood, has inevitable negative health implications. There are almost always barriers to teaching young children how to make healthy eating and activity choices. That's why there are so many children struggling with excess weight in early childhood classrooms today. By helping to change the way kids think about food and exercise, early childhood educators can impact the physical, cognitive, and social and emotional development of millions of young children. That's certainly worth the effort. One barrier to getting this done--the lack of practical, effective teaching tools to address the problem--is coming down. And that's good news for teachers who are ready to make a difference. (Contains 2 online resources.)
