Adults should eat less than the equivalent of 6
teaspoons of sugar a day if they are to avoid health risks such as weight
gain and tooth
decay linked to sugary diets, the World Health Organisation said.
Issuing draft guidelines calling for a new sugar limit of less than 5.0% of
daily energy intake, the United Nations health agency said its recommendations
were based on "the totality of evidence regarding the relationship between
free sugars intake and body weight and dental
"Obesity now affects half a billion people in the world, and it is on
the rise in all age groups and particularly in low- and middle-income
countries," said Francesco Branca, the WHO's director of nutrition for
health and development, adding that free sugars were a key culprit in that
Reduced intake of free sugars
Free sugars include monosaccharides and disaccharides that are added to
foods by manufacturers, cooks or consumers, and sugars naturally present in honey,
juices and fruit concentrates.
5% of total energy intake is equivalent to around 25 grams – or around 6
teaspoons – of sugar a day for a normal weight adult.
sweeteners may cause weight gain
"WHO recommends reduced intake of free sugars throughout the
life-course," the agency said in a statement.
It said the 5.0% level should be a target for people to aim for – calling it
a "conditional recommendation" – but also reiterated a "strong
recommendation" that sugar should account for no more that 10% of total
"There is increasing concern that consumption of free sugars –
particularly in the form of sugar-sweetened
beverages – increases overall energy intake and may reduce the intake of
foods containing more nutritionally adequate calories," it said.
This can lead "to an unhealthy
diet, weight gain and increased risk of non-communicable diseases (such as
heart disease, diabetes and cancer)."
Non-communicable, or chronic, diseases are the world's leading causes of ill
health and death, killing more than 36 million a year with more than 90% of
these premature deaths in poorer countries.
Asked whether he would characterise sugar as "the new tobacco" in
terms of its threat to public health if consumption levels are not reduced,
Branca said sugar was one key risk factor which, combined with others like fat,
salt and lack of exercise, could be compared to smoking.
Research published last month in the journal JAMA Internal Medicine
suggested the risk of dying of heart disease is higher among people who eat a
larger percentage of their calories from added sugars. And the risk was also
higher for people who had seven or more sweetened drinks a day.
"The consumption of sugar-sweetened beverages has to be done with great
care – particularly in children," Branca said. "This is an area where
more intense action needs to be taken."
Branca acknowledged the new guidelines "may not be popular amongst
sugar producers" but said the WHO would resist any unjustified pressure or
lobbying from the food and sugar industries to change them.
"If pressure comes on the organisation we are very well equipped to
deal with (it)," he said. "I don't anticipate any problem in that
