New research discovers no link between childhood obesity and school junk food

Schools nationwide have been banning junk food from their campuses in an effort to curb the nation's childhood obesity epidemic. But a new study now says that's not necessary: the researchers found no link between obesity and attending a school where candy, potato chips, and other junk food treats were available, the New York Times reported on January 23.

So if junk food at school's not to blame, what is? "Food preferences are established early in life," noted the study's lead author, Jennifer Van Hook, professor of sociology and demography at Penn State. It is the influence at home, multiple studies show, that determine a child's weight fate.

For example, a recent study also showed a link between mother and tot bonds and obesity later in life.

Dr. Bal M. Rajagopalan, better known as Dr. Raj, is an ABC News medical consultant.  He says that the national childhood obesity epidemic is due in part to "kids being less active," while foods "have 30 percent more calories than 20 years ago." His advice to parents: "Make the child walk to school. Show the kids an example by eating well with the kids."

His advice resonates with Jennifer Hudson, who recently emphasized her son's role in her diet success. Added Dr. Raj: "Your kids will follow by example and as parents, if we practice what we preach, the message is more powerful."
