Research finds sugar content in soft drinks drops by 29 percent in UK

New research suggests that individual soft drink companies in the UK are making a sizeable contribution to sugar reduction, with eight out of the top 10 companies reducing the sugar content of their products by 15 percent or more.

There is said to have been considerable pressure on industry recently to reduce the sugar content of soft drinks, and in April 2018, the British government increased this pressure by introducing the Soft Drinks Industry Levy (SDIL). 

Researchers from the University of Oxford have analysed the nutritional information of a range of soft drinks in the UK, including carbonated drinks, concentrates, 100 percent juice, juice drinks, energy drinks, sports drinks and bottled water. They combined this with sales data from 2015-2018 and found that there has been a 29 percent (average) reduction in sugar content. 

“This study is not designed to evaluate the specific effects of the SDIL, but nonetheless shows that sustained pressure on business, including using fiscal measures, has led to a striking reduction in the sugar content of soft drinks in the UK,” remarked lead researcher Lauren Bandy.

Coca-Cola and Britvic have reduced the total quantity of sugars they sold in drinks by 17 percent and 26 percent respectively, although the sugar content of their flagship brands Coca-Cola and Pepsi reportedly remained unchanged. There were increases in volume sales of sugars in drinks sold by Innocent and Red Bull, and the sugar content of their products was largely unchanged, but the companies had seen increases in overall volume sales, according to the researchers.

The analysis shows that approximately three-quarters (73 percent) of the reduction seen in the amount of sugar sold in soft drinks was due to reformulation of existing products or the introduction of new, lower sugar drinks, and 27 percent was due to changes in purchasing behaviour.

“It is encouraging to see such a large reduction in sugars sold in soft drinks. This is largely a result of change in the composition of drinks, but there have also been shifts in consumer purchasing behaviour, with more consumers choosing drinks with low or no sugar content. These changes are likely to be due to a combination of government action, mostly through the SDIL, changes in marketing practices on the part of the soft drinks industry, and greater awareness of the harms caused by sugary drinks among consumers. They show that it is possible for improvements in public health to be consistent with successful business practices,” Brandy said.

“National and international governments are calling for change in the food industry to improve public health. This new method allows researchers to monitor the progress being made and to make this information available to the public. This external scrutiny will hopefully encourage more positive and rapid action by the food industry to achieve healthier diets,” added co-author Susan Jebb, Professor of Diet and Population Health at the Nuffield Department of Primary Care Health Sciences, University of Oxford.
