People need to halve their intake of added to sugar to food and drinks in order to tackle the obesity crisis, according to a draft report by the Scientific Advisory Committee on Nutrition (SACN).
Under new guidelines to be considered by the Department of Health, one can of fizzy drink will take a typical adult up to the proposed 5% daily allowance, without factoring in sugar from any other source.
Experts say the consumption of free sugars should be lowered from the current recommendation of 10% of dietary energy intake to 5%.
This is the equivalent of 25 grams of sugar (five or six teaspoons) for women and 35 grams (seven to eight teaspoonfuls) for men.
It's already clear most of us eat too much, so the focus really needs to be how, as a country, we go about changing our sugar-eating habits.
Sugar can be labelled in multiple ways, making it harder to spot.
