High school kids who watch too much TV are likely to have bad eating habits five years in the future, according to a new study.

Researchers from the University of Minnesota followed almost 2,000 high and middle school children and found that TV viewing times predict a poor diet in the future.

The authors found that those high school kids who watched more than five hours of television per day had a lower intake of fruits, vegetables, whole grains and calcium-rich foods and higher intakes of snack foods, fried foods, fast food, soda and transfat.

"These less-than-healthy foodstuffs are commonly advertised on television, while healthy foods rarely receive the same publicity. Although young people may be aware that many foods advertised on television are not healthy, they may chose to ignore or do not fully realize the consequences, because the actors they see advertising and eating the foods in the commercials are usually not overweight," said lead author Daheia Barr-Anderson.

Teens in the study were broken into groups based on whether they watched less than two hours of TV a day, between two and five hours a day, or more than five hours a day.

The work was published in the International Journal of Behavioral Nutrition and Physical Activity.
