17 Oct 2017 --- Introducing a small levy to the price of sugar-sweetened beverages (SSBs) sold in Jamie Oliver’s Italian restaurants across the UK is likely to have contributed to a significant decline in SSB sales, according to new research published in the Journal of Epidemiology & Community Health. The celebrity chef and food campaigner has collated the results of a study that has been running in his 37 Italian restaurants exploring the effects a 10 pence sugar tax had on sales of sugar-sweetened beverages.
