How much of one's ancestral identity must one give up to live in the modern world? - Hadley Freeman

An eating disorder is a mental illness. It is characterised by the sufferer's belief that they are too fat, that to survive on 500 calories a day is the norm, that doctors are trying to make them fat, that weighing more than seven stone is obese and unacceptable. So far, so paranoid.
Yet the current culture of skinniness legitimises the anorexic's beliefs. That is where the danger lies. Once a person becomes severely anorexic, they are usually too locked into their own little world to care if Jennifer Aniston is now a size six, or to read about Jodie Kidd's protruding hip bones. But when they try to recover, it is very difficult to shake off these old beliefs when every other magazine cover seems to validate them.

On Monday I went to the Jewish Vigil for Israel opposite Downing Street. It was nice, but it was also strange, because everyone I could see there was clearly Jewish: the men wore kippahs and tallits, and everybody knew the words to Hatikvah, Israel's national anthem. Across town a pro-Palestinian rally was happening. I looked at the photos in the papers in the next day and was struck by what a mixed crowd it was. Young Muslims, older white people, everyone marching together in defence of — what? Pogroms? Meanwhile, the Jews just had themselves. Now we know.

Anorexics tend to be unreliable witnesses when in the grip of the illness and, at times, there is an oddity about this book, a curious sense of separation between the suffering younger self and the aloof older self, but Freeman is a brave, illuminating and meticulous reporter and uses her experience wisely.
