Scientific experts: Sugar intake 'should be halved' A committee of scientific experts is calling on the UK government to halve the recommended daily intake of sugar. Advisers on nutrition say not more than five percent of daily calories should come from added sugar, which is about seven level teaspoons. The guidelines are in line with new World Health Organization proposals. According to existing research, all age groups in the UK consume at least twice this limit. The Scientific Advisory Committee on Nutrition, which advises Public Health England and other government agencies on nutrition, wants the recommended daily intake of sugar to be halved to reduce the risk of obesity and improve dental health.
