Do you think that magazines influence their audiences eating habits?

Magazines like Bliss, Mizz, Cosmo Girl etc
Articles, pictures, personal letters etc

I am doing my literature review for my psychology degree on this very subject. There is a lot of material out there, most of it linking the influence of magazines to the incidence of disordered eating although most suggest the person needs to be susceptible to it (i.e. through having a pre-existing low self esteem or an attentional bias to body image). Try google scholar for relevant articles.
