BACKGROUND The consumption of free sugars in the UK is more than double the guideline intake for adults and close to triple for children, with soft drinks representing a significant proportion. The aim of this study was to assess how individual soft drink companies and consumers have responded to calls to reduce sugar consumption, including the soft drink industry levy (SDIL), between 2015 and 2018. METHODS This was an annual cross-sectional study using nutrient composition data of 7377 products collected online, paired with volume sales data for 195 brands offered by 57 companies. The main outcome measures were sales volume, sugar content and volume of sugars sold by company and category, expressed in total and per capita per day terms. RESULTS Between 2015 and 2018, the volume of sugars sold per capita per day from soft drinks declined by 30%, equivalent to a reduction of 4.6 g per capita per day. The sales-weighted mean sugar content of soft drinks fell from 4.4 g/100 ml in 2015 to 2.9 g/100 ml in 2018. The total volume sales of soft drinks that are subject to the SDIL (i.e. contain more than 5 g/100 ml of sugar) fell by 50%, while volume sales of low- and zero-sugar (< 5 g/100 ml) drinks rose by 40%. CONCLUSION Action by the soft drinks industry to reduce sugar in products and change their product portfolios, coupled with changes in consumer purchasing, has led to a significant reduction in the total volume and per capita sales of sugars sold in soft drinks in the UK. The rate of change accelerated between 2017 and 2018, which also implies that the implementation of the SDIL acted as an extra incentive for companies to reformulate above and beyond what was already being done as part of voluntary commitments to reformulation, or changes in sales driven by consumer preferences.

从 2015 年到 2018 年，英国软饮料的糖销售量减少。

背景 在英国，游离糖的摄入量是成人摄入量的两倍多，儿童摄入量接近三倍，其中软饮料占很大比例。本研究的目的是评估在 2015 年至 2018 年期间，个别软饮料公司和消费者如何响应减少糖消费的呼吁，包括软饮料行业税 (SDIL)。方法这是一项使用营养素的年度横断面研究在线收集的 7377 种产品的成分数据，以及 57 家公司提供的 195 个品牌的销量数据。主要结果指标是销售量、糖含量和按公司和类别销售的糖量，以总量和人均每天表示。结果 2015 年至 2018 年间，软饮料人均每天售出的糖量下降了 30%，相当于人均每天减少 4.6 克。软饮料的销售加权平均含糖量从 2015 年的 4.4 克/100 毫升下降到 2018 年的 2.9 克/100 毫升。受 SDIL 约束的软饮料的总销量（即含糖量超过 5 克/100 毫升） ml 糖）下降了 50%，而低糖和零糖（< 5 g/100 ml）饮料的销量增长了 40%。结论 软饮料行业为减少产品中的糖分和改变其产品组合而采取的行动，加上消费者购买的变化，导致英国软饮料中销售的糖的总量和人均销售额显着下降。2017 年至 2018 年间变化速度加快，
