“We don’t have junk food — you’re not allowed to bring junk food here,” Booker told KYW Newsradio today.  “So you don’t bring red dye juice.  (And) the teachers have noted that there are different behaviors going on in the classroom.”

Mayor Nutter and Philadelphia’s efforts to fight obesity are featured in the documentary series.
