Junk Food = Junk Behavior?

Does eating poorly lead to poor behavior? This article seems to think so, and they have some scientific evidence to back it up.

We all know the saying, “You are what you eat.” So if we eat bad, does it stand to reason we’re not as well behaved? This article from CNN suggests people are getting ruder. The suggestion is that our high-paced society is causing the rudeness. But what if it was poor nutrition?

The article also reminds me a scene from Super Size Me. Actually, the beginning of this article references (I think) the same High School for troubled students. Kids start eating better, and their behavior gets a whole lot better.

What do you think? Do you think poor nutrition causes poor behavior?
