An emerging trend to tax sugar sweetened beverages and other junk foods: overregulation or an effective way to modify dietary behaviours?

Abstract

Abstract Dietary behaviours have an important impact on rising prevalence of noncommunicable diseases responsible for 71% of deaths globally/year. Dietary behaviours also have a growing impact on quality of life, disabilities, as well as economic stability of health systems. In order to overcome the growing impact, many countries are looking for instruments to modify dietary habits of individuals. In the study presented here, we looked at solutions implemented in different countries in terms of junk food taxation, with regard to the political processes related to their implementation, adopted models of taxation, as well as their impact on social and economic reality. Throughout the world, several countries have adopted dietary taxes, such as sugar, fat, salt and soda taxes, while the other are planning or considering doing so. So far there is only one example of withdrawal from the tax that has been implemented. There are different models of taxation, including flat rates, percentages of the basic price and progressive rates on the amount of the component being subject to taxation. These solutions continue to be controversial and subject to intensive discussions in many countries. Nonetheless, the existing evidence shows that the impact on dietary habits seems to be positive.
