I am pediatrician specializing in the area of preventive cardiology, nutrition, and epidemiology, and I read with interest the recent article by Wyshak,1 which concluded that soda (especially cola) consumption by teenaged girls increased their risk of bone fractures. While I believe this is an important area of research, there are methodologic problems with this study that call into question the author's conclusions.
