Yahoo health Experts has this article about 2x new eating disorders people who study these things have run into. They don't seem to be medically recognized however, I feel pretty obsessive about food at times and understand how these conditions might be of interest to the community here?

2) Orthorexia, defined as "an obsession with healthy eating." which sounds ok but they explain can cary "serious risks" for those who take them too far.
