WHO: Daily sugar intake 'should be halved'

People will be advised to halve the amount of sugar in their diet, under new World Health Organization guidance.

The recommended sugar intake will stay at below 10% of total calorie intake a day, with 5% the target, says the WHO.

The suggested limits apply to all sugars added to food, as well as sugar naturally present in honey, syrups, fruit juices and fruit concentrates.

UK campaigners say it is a "tragedy" that the WHO has taken 10 years to think about changing its advice.

The recommendation that sugar should account for no more than 10% of the calories in the diet, was passed in 2002.

It works out at about 50g a day for an adult of normal weight, said the WHO.

However, a number of experts now think 10% is too high, amid rising obesity levels around the world.
