Could Food Choices Be a Factor in the Shooting of a US Congresswoman?
The U.S. is still reeling from another tragedy -- the attempted assassination of Congresswoman Gabrielle Giffords, and the murder of several civilians during the attempt.

Many are asking what the cause might have been -- whether it was pervasive, over-the-top violent rhetoric in the culture, or simply mental psychosis.

But, even if the former, there is still the underlying cause of mental psychosis to consider.

And what if people are lashing out with such destructive force, at Columbine, Virginia Tech, and now Arizona, not because of what they are hearing, but at least in part because of what they are eating?
