  NEW YORK (Reuters Life!)-Parents wanting their children,particularly teenagers,to develop good eating habits should make sure they eat meals together,a new study suggests.

  In one of the first long­term studies to look at the benefits of family meals,researchers at the School of Public Health at the University of Minnesota found that family meals have a great influence on adolescents(青少年)because they encourage healthy eating habits and good nutritional(营养的)choices.The study was published in the Journal of Nutrition Education and Behavior.

  "These findings suggest that having regular family meals from early to middle adolescence has a marked beneficial effect on the development of healthful behaviors for youth," said Teri L.Burgess­Champoux,who worked on the study.

  "The importance of shared mealtime experiences during this key developmental period should be emphasized(强调)to parents,healthcare providers and educators."

  The researchers examined information from Project EAT,a study that looked at which socio­environmental,personal,and behavioral factors(因素)influence the eating habits of nearly 400 children.

The students completed a questionnaire(问卷)in 2012 and 2013 when they were 12 to 13 years old and another as middle adolescents five years later.
