Memoirs of a fast-food virgin

Morgan Spurlock decided to eat only McDonald’s food for 30 days. The result? An award-winning film and a very bad liver. My Observer colleague Tim Adams repeated the experiment in Britain, but after seven days of burgers and shakes his body told him to stop. His sobering account is here. I wasn’t entirely surprised by Spurlock’s experience over a whole month. But the thought that even a week’s exposure to McCrap could do perceptible damage comes as a bit of a shock.
