What a sad, confused woman that journalist is. She took a psychological condition that causes people to become malnourished due to their obsession and essentially labeled anyone concerned about their food as a neurotic nutcase.
I would like to see the research which demonstrates the characteristics of those who purportedly suffer the highest rate of this disease. I'm willing to bet you'll find their demographic to be true but their reasoning circumspect. You could probably make a case and stratify all varieties of OCD by this nonsense you are calling characterization. And worse this columnist masks it as possibly common amongst any peer who is concerned with healthy eating.
