These briefing notes utilise publicly available UK nationally-representative dietary intake data and overweight/obesity prevalence data in England. Due to the repeated measures of dietary intakes over the last couple of decades, the UK sugars intake data is one of the most comprehensive datasets, globally. Over time, free sugars intakes have decreased, whilst overweight and obesity prevalence continues to increase. This is the first part of a larger ongoing WSRO-funded project looking at global trends in intakes of sugars and overweight and obesity prevalence.
