Problems caused by social media

Every day the media reports on models and sportsmen who have a thin body and this causes problems, especially in teenagers. This problems are basically nutrition problems like bulimia and anorexia. 
This problems are caused by psicology problems, that make a person think that he or she is fat and because of that, the person doesn't eat much food or eat a lot and then he barfs it. 
This problem is increasing every day and i think that social media must tell more often about healthy habits and less about famous people with perfects bodies.
