Teaching kids about eating well: video game

I’ve just been sent this article about a Kaiser Foundation/Scholastic video game designed to teach kids about healthy eating. It’s in the form of a detective story–“Incredible Adventures of the Amazing Food Detective.” The article points out the irony of using video games to teach about diet and activity, but never mind. I can’t figure out how to make it work on my new computer so I haven’t tried it. Is it worthwhile? Useful? Fun for kids?
