Families who want kids to grow up thinner and smarter do well to keep them away from the television as toddlers. In a new study published in Archives of Pediatrics & Adolescent Medicine, Dr. Linda S. Pagani, a professor at the Université de Montréal and researcher at the Sainte-Justine University Hospital Research Center, concluded: “We found every additional hour of TV exposure among toddlers corresponded to a future decrease in classroom engagement and success at math, increased victimization by classmates, a more sedentary lifestyle, higher consumption of junk food and ultimately, a higher body mass index.”.
