Professor John Britton, a respiratory physician from Nottingham City Hospital, has called for children to be given free fruit at school to improve their lungs and general health at the summer meeting of the British Thoracic Society. He said the government should also consider levying a 'junk food tax' on fizzy drinks and crisps to be spent on health promotion campaigns, a review of school meal policies to improve minimum standards, and a 'supermarket summit' to review pricing policies for fruit and vegetables. 'More and more evidence is accumulating that a balanced diet can help children and adults breathe more easily. The government must consider ways to improve child nutrition, ' Professor Britton said.
