mmm, didn't find the bit in the article mentioning vegetarianism, just vegetables (meat eaters eat those too). Also, don't forget that the article only says that these pills are not beneficial in preventing cancer, not that they're a waste of time. Not that I'm advocating pills over a balanced diet, but misquoting scientific papers is something we should leave to the media.
Incidently, If you read the bad science column in the guardian, you'd know this already - it's on-line (look in the science section of guardian.co.uk), or in the saturday guardian. It's all about mis-reporting of science in the media, and is very informative and funny too. Unlike myself.
