GOP: Party of Big Pizza — and obesity?

Last year at this time I started working on a story about childhood obesity in a couple of small towns in Ventura County, and how different the picture looked in an upscale, mostly white town such as Ojai, where childhood obesity runs behind the national average of about 35%, and how it looks in the poorer, mostly Latino town of Santa Paula, where childhood obesity prevalence is among the highest in the state, at about 48%.

Interviewing the director of food services for Ojai's schools, I learned that she does not allow frozen pizza at all for her students eating school lunches, and did what she could to discourage parents from bringing pizza to after-school events. By contrast, I heard from a student at Santa Paula High, most students went for the frozen pizza at the high school every day.

Naturally I wondered if there was a connection to the high rates of obesity, but my adviser at USC/Annenberg's Health Reporting fellowship, discouraged me pointing the finger of blame at a single food for Santa Paula's obesity problem. 

So my ears perked up when today I came across a characteristically strong but unusually wide-ranging column from Paul Krugman at the NYTimes, who argues that based on contributions, it's fair to say that Republicans are "the party of Big Energy and Big Food…and in particular, the party of Big Pizza."

Could caloric frozen pizza explain the obesity problem among kids eating free and reduced lunches?
