Teenagers who spend hours in front of the television mayhave a poorer diet, a new study shows. It is not clear, researchers say,whether television itself is the reason, but it is possible that things likesnacking in front of the TV or seeing ads for junk food influence young people’s diets.

The study included nearly 1,400 high schoolstudents. It showed that those who watched TV for five hours or more every dayhad less healthy diets than other students five years later. As a group, theyate fewer fruits and vegetables, but ate more fast food, snack products andfried foods.

“We’re not ableto tell why,” lead researcher Dr. Daheia J.Barr-Anderson said. “But we have some speculation(推测).” People who spend a lot of time in frontof the TV, especially teenagers, may have more snacks. It may influence theirlong-term diet quality. It’s also possible that TV adsfor fast food, sweets and snacks make teenagers eat more of those foods. TVtime might also replace exercise time for some kids.

The researchers found a clear relationshipbetween TV time during high school and diet quality of the young. The heaviestTV viewers ate the most junk food five years later, and those who’d watched fewer than two hours everyday had the most fruits and vegetables.

According to Barr-Anderson, the findingssupport experts’ advicethat children should watch no more than two hours of television every day. “Parents should cut the TV time.”Barr-Anderson said. She advised that parents set a good example by eatingright, being physically active and controlling their own TV time.
