Nielsen Brandbank and FoodMaestro have analysed 2,268 soft drink products across the past 4 years to understand how a sugar tax could be impacting manufacturer and consumer behaviour changes. We found that the average sugar content of soft drinks has decreased by an average of 1.3 grams per 330ml can from 2014 to 2018 noting that the decrease started pre-sugar tax. Whether the tax itself has accelerated the decrease remains to be seen, but the important measure for now would be the direct impact on consumption and health outcomes. Enforcing a sugar tax to soft drink manufacturers on drinks with over 5 grams of sugar per 100ml doesn’t help consumers find healthier drinks but we can see that many manufacturers have reformulated their products, over the past 4 years, to have more products with low to no sugar.
