3.Parents should think twice before rewarding their children's good behaviour with sweets, according to a
leading nutritionist.
Professor Susan Jebb, of Oxford University, says family attitudes should change as part of a wider strategy on tackling obesity（肥胖）- and there should be an alternative to the 'easy option' of handing out sweets to youngsters.
Speaking to the Sunday Express, Prof Jebb said: 'Unless you instill(灌输) good eating habits from a young age, it is likely children will grow up to become overweight adults.But it is very difficult to persuade parents who see their children, who are a healthy weight, of the risks ahead.'Unlike with smoking, where the benefits of giving up are obvious with evidence showing that every single cigarette shortens your life, the same cannot be said for every single biscuit you eat.'
She also welcomed last week's comments by David Cameron that Britain's obesity 'crisis' should be treated as seriously as smoking and that a tax on sugary drinks could be back on the agenda（议程）. The Prime Minister hinted at an extraordinary U-turn amid growing public support for a 20 per cent levy.He said: 'I don't really want to put new taxes on anything but we do have to recognise that we face something of an obesity crisis'.
Mr Cameron said the costs of diabetes, heart disease and cancer treatment for the overweight costs the NHS huge sums.He added: 'We do need to have a fully-worked-up programme to deal with this problem and address these issues in Britain and we will be making announcements later in the year'.
Experts have also warned that obesity - fuelled by large amounts of sugar - is escalating at such a rate that it will cause almost 700,000 additional cases of cancer within the next 20 years, experts have warned.They say that being overweight is already 'the new norm' and predict that four in ten adults will be obese by 2035.
Estimates also show that by this time obesity-related illnesses, including diabetes and heart disease, will cost the NHS more than ￡7.5 billion a year.
