He and I are both fellows of the American College of Nutrition. He's designed nutritional programs for Olympic athletes, NBA players and major league baseball players. More importantly, he's spent a great deal of his career seeking to improve mental health through nutrition.
"I started off in the hard science. I was an experimentalist," Walsh says. "I worked, in the beginning, in the nuclear field ... with places like Los Alamos, the Institute for Atomic Research and University of Michigan Research Institute. I wound up at Argonne National Laboratory. While working as a scientist there, I started a volunteer project at the local prison, Stateville Penitentiary.
I eventually got really interested in why people were violent ... [W]hen we started the ex-offender program, I got to meet the families that had produced a criminal. I found some wonderful families, caring and capable families, that have other children who turned out just fine ...
I began to realize we didn't understand why people had bad behavior. We then asked the question, 'Could it be something related to their brain chemistry or the body chemistry?'... I started doing lab studies of their blood, their urine and hair. I found out that they were very, very different from the rest of the population. That's how I got started."
