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.
The Scientific Advisory Committee on Nutrition (SACN), which advises Public Health England and other government agencies on nutrition, wants the recommended daily intake of sugar to be halved to reduce obesity risk and improve dental health.
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.
“The clear and consistent link between a high-sugar diet and conditions like obesity and type 2 diabetes is the wake-up call we need to rethink our diet.
“Cut down on sugars, increase fibre and we’ll all have a better chance of living longer, healthier lives.”
Free sugars
The guidelines, which apply from the age of two, are in line with new World Health Organization proposals.
Prof Judith Buttriss of the British Nutrition Foundation said the type of sugar targeted was known as free sugar – all the different types of sugar in the diet, excluding the sugars that are found naturally in fruit and milk.
“What the recommendations are saying is we’ve all got to cut down so we’re getting no more than 5% of our total from these free sugars,” she told the BBC Today Programme.
According to health experts, 5% of daily energy intake is the equivalent of 19g or five sugar cubes for children aged four to six, 24g or six sugar cubes for children aged seven to 10, or seven sugar cubes for those aged 11 and over, based on average diets.
The main sources of sugar in the diet are sweetened drinks and cereal, confectionery, fruit juice, and sugar added at the table.
A single can of fizzy drink contains about nine teaspoons of sugar.
The British Dental Association (BDA) has called on the government to take heed of the latest advice.
Tooth decay is the biggest cause of hospital admissions among young children.
Mick Armstrong, chairman of the BDA, said: “The government now has the evidence and a clear duty to send the strongest possible signal to the food industry that while added sugar might be helping their sales, it is hurting their customers.”
The food industry has said calories in household foods and drinks have been gradually lowered in recent years, including sugar reductions and changes to portion sizes.
The Food and Drink Federation described the goals set out in the report as “stretching”.
Director general Ian Wright said: “The most thorough scientific review of carbohydrates and health carried out in recent years should leave people in no doubt that sugars can be enjoyed safely as part of a varied and balanced diet.”
He added: “Demonising any one ingredient in the obesity debate isn’t helpful.”
