A committee of scientists has advised the government to halve the current recommended daily intake of sugar.Nutrition experts say no more than 5% of daily calories should come from added sugar - about seven teaspoons.Most people consume at least twice this limit.The government has said it will accept the recommendations and will use them to develop its national strategy on childhood obesity, which is due out later this year.Prof Ian Macdonald, chair of the working group of the committee, said: "The evidence is stark - too much sugar is harmful to health and we all need to cut back in order to improve our own health.The clear and consistent link between a high-sugar diet and conditions like obesity and type 2 diabetes is the wake-up call, by cutting down on sugars and increasing fibre we'll all have a better chance of living longer, healthier lives."
