Powerful policy: tax on sugar sweetened beverages One key element of a comprehensive strategy is the implementation of fiscal policies, because they have multiple effects. A price increase for unhealthy foods, for instance, motivates consumers to buy less of these products. For sugar sweetened beverages, price elasticity of demand, i.e. the change in demand as a reaction to price changes, is –0.79 to –1.3 [18, 19]; that means that a price increase of 10 % would decrease con- sumption by 7.9–13 %. Persons with low incomes, young people, and overweight people are particularly price sensitive [18]. Modeling and experimental studies point out that a tax increase raising the price of sugar sweetened beverages by at least 20%, likely would decrease the consumption and the associated health consequences proportionate to the price increase [18]. Simultaneous significant reduction of the value-added tax on healthy foods like fruits and vegetables could avoid a disproportionate burden on low-income individuals and at the same time promote switching to healthy foods [20]. Ideally, the health consequences – particularly obesity – would decline in the long term as a result of the reduced consumption of unhealthy products. At the same time, taxes on unhealthy foods are an incentive to the industry to change unhealthy products by improving their nutritional quality – this, too, contributes to a healthier diet [18, 21]. Beyond that, taxes on unhealthy foods increase government revenue, which could be earmarked for obesity prevention [18]. Price-related measures are particularly sig- nificant because they address the lower income segment of the population, where excess weight and obesity are more prevalent than among people with higher incomes. This way, price-related measures can even contribute to mitigating health inequalities [22]. According to intervention and modeling studies, a tax on sugar sweetened beverages has the largest effect of all pricing measures. It has the potential to positively influence consumer behavior, particularly if it is imposed simultaneously with financial incentives on fruits and vegetables [18]. Several countries currently levy a tax on sugar sweetened beverages, among them Mexico, France, Ireland, and the United Kingdom, other countries are considering the option [18]. However, the industry has prevented such a tax from being introduced in several countries. Denmark, for instance, cancelled a proposed sugar tax in 2012 in response to intensive lobbying by the sugar industry. Finland refrained from an increase on the tax on sweets that has been in effect since 2010 because of a complaint by the Finnish Food and Drinks Industries’ Federation to the European Court of Justice [23, 24]. First evaluation studies in countries with a tax on sugar sweetened beverages indicate that these taxes are effective, at least in the short term: They lead to price increases and are thereby passed on to consumers, although the extent differs between the various types of taxed drinks and the point of sale [23, 25–27]. Also, the tax influences consumer behavior: Demand declined in all countries that were evaluated [23]. In Mexico and in Berkeley (California/USA), the tax caused a reduction in purchases of sugar sweetened beverages of 6 and 9%, respectively, and sales of untaxed drinks, particularly water, increased by 4 and 15% [28–30]. This trend continued in Mexico during the second year after the introduction of the tax [31]. The effect varied in intensity depending on socioeconomic status: low-income households reduced the purchases of sugar sweetened beverages more significantly [29, 31, 32]. There is no evidence as yet to what degree these taxes have long-term effects on consumer behavior, body weight, and public health. rence, influence, regulation, tax”, and lobby control organizations were industry and its lobby organizations were linked with operators.
