The high profile campaign by Jamie Oliver to push healthy school dinners has been criticised by the new Health Secretary Andrew Lansley for having the opposite effect. Lansley told doctors at the British Medical Association (BMA) conference in Brighton that there must be an evidence-based approach to dealing with public health issues like food and obesity. He said: "Jamie Oliver, quite rightly, was talking about trying to improve the diet of children in schools and improving school meals, but the net effect was the number of children eating school meals in many of these places didn't go up, it went down. "So then the schools said: 'It's OK to bring packed lunches but we've got to determine what's in the packed lunches.' Oliver responded by saying Lansley’s views were an insult to school dinner ladies. He said any problems were due to there being too little funding available to train school-catering staff properly.
