The issue of eating disorders is one that is very important, especially for girls. You also mention how eating disorders can be triggered in girls by psychological and emotional responses to their environment, such as the need for control, loneliness, perfectionism and a desire to fit in. But one thing that I think we should consider is the possibility that people first try to deal with these personal issues by DIETING. Eating disorders are what develop AFTER the initial attempt of dieting. So what if we taught young kids how NOT to diet? Would the chain from trying to deal with personal issues to dieting to developing eating disorders be broken? We can use "intuitive eating", or a way of listening to our bodies to determine when, how or what we eat without any rules or limitations about food, to reject the diet mentality that, as you say, is "entwined in the fabric of adolescent society". If girls develop a healthy relationship with food they are less likely to go on and off of diets in attempts to lose weight, and they will learn how to deal with their personal issues in other ways that do not involve the usage of food or damage to their bodies. This, in turn, could ultimately lead to the prevention of eating disorders. It is about time we see the damage that dieting has on our society and, if possible, banish it completely.
