     Meals at the family dinner table could be the key to preventing a generation of  teenage girls from

developing eating disorders (紊乱).

     New research shows girls who regularly have family meals are much less likely to adopt extreme

weight-control behaviors such as vomiting, and using diet pills.

     The research, published in the international journal Archives of Pediatrics and Adolescent

Medicine, surveyed students aged 13 to 17 in 2003 and followed them up five years later. Regular

family meals were found to have a protective effect regardless of the age, weight, socioeconomic status,

dieting habit or relationship with the family.

     Belinda Dalton, director of the eating disorder clinic The Oak House, said eating with family helped

"normalize" young people's relationship with food.

     "When teens are feeling that they are not managing, they turn to something that they can control and

food is something available and accessible for them to control. Clearly, if they are sitting with their family

on a regular basis, then their family can be more in control of their eating," Ms Dalton said.

     "It's about young people feeling connected within their family, and that builds self-esteem and a sense

of worth and works very actively against someone developing an eating disorder.

     An eating disorder expert, Kirsty Greenwood, said meal times were often difficult for sufferers. "It's

typical that they feel very ashamed of their eating habits and often won't eat with other people. Perhaps

it's because they haven't experienced the important of the family meal while growing up," she said.

     The study found eating regular family meals made no difference to the future eating habits of boys.
