**6. Nutritional knowledge of added sugar in SSBs**

The notion of nutrition knowledge has been found by Worsley [19] to be very vague and hence there is evidence of a lack of clarity between what nutritionists deem as knowledge about nutrition and what consumers think is important to know about nutrition [19]. Worsley [19] argues that nutrition knowledge cannot affect consumers' food behaviours to the extent that it can change them. For instance, once an individual is aware of the amount of added sugar in their favourite SSB they will not necessarily stop consuming the SSB purely based on the fact that they possess the nutritional knowledge [19]. However, although nutrition knowledge may not have the power to create change on its own, Worsley [19] acknowledges that if nutrition knowledge is paired with other variables, for example, if a consumer has nutrition knowledge but also has goals to lead a healthier lifestyle, their food behaviours have a good chance of changing [19]. This is confirmed by Grunert et al. [21] that nutrition knowledge is associated with being able to understand the nutrient content depicted on the food label.
