Questions have been raised over whether cakes should be brought into the office.

The head of a food watchdog has suggested people should not bring cake into the office for the sake of their colleagues’ health.
Professor Susan Jebb claims the practice is as harmful as passive smoking.
She told The Times in London that employees should be more wary of their colleagues before bringing in sweet treats.
Prof Jebb is the chairwoman of the Food Standards Agency and a professor of diet and population health at the University of Oxford.
She lamented that the advertising of junk food prevents people making healthier choices and was frustrated by delays in introducing a television watershed for junk food advertising.
Prof Jebb urged doctors to be more willing to broach the topic of patients’ weight and offer diet help.
She believes that the conversation of weight with most doctors is ignored, and is damaging towards the nations health.
Personal willpower is not enough to to avoid overeating, according to Prof Jebb, who thinks society is plying people with food.
