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?
Soy infant formula has damaging effects on the development of the brain, but soy is a common ingredient in many processed foods and soy products are being mistakenly touted as a healthy option. Copper toxicity can also cause mental disturbance, and a diet high in grains and low on animal products is also likely to be high in copper. Animal-based omega-3 fats are crucial for fetal brain development.
Writing in her blog, Kimberly Hartke, a publicist for the Weston A. Price Foundation, says:
"Our USDA dietary guidelines currently advise to restrict meat and eggs, in favor of vegetables and grains ... Could our government policies be misguided and leading us down the wrong path? ... Let's stop focusing exclusively on the environmental influences in the home and in our culture, but start looking at the internal influence of the Standard American Diet on mental health."
