Taxing sweet snacks may bring even greater health benefits than taxing sugar-sweetened drinks

The UK Government levy on sugary drinks producers started in April 2018. This will potentially influence the cost of a large range of non-alcoholic beverages. Our new study (published 26th April 2018) looks at how increasing the price of snack foods might compare in impact. We found that a 10% increase in the price of sweet snacks could lead to a similar reduction in consumer demand as the same price increase for sugar-sweetened drinks. However, such a price increase is estimated to have knock-on effects that may further reduce purchases of sugar-sweetened drinks and other snacks. Furthermore, as sweet snacks provide twice as much sugar in the diet as sugar-sweetened drinks, the overall reduction on sugar intake could be even greater than that observed with price increases for sugar-sweetened drinks.
