Taxes and subsidies are increasingly being considered as potential policy instruments to incentivize consumers to improve their food and beverage consumption patterns and related health outcomes. This study provided a systematic review of recent U.S. studies on the price elasticity of demand for sugar-sweetened beverages (SSBs), fast food, and fruits and vegetables, as well as the direct associations of prices/taxes with body weight outcomes. Based on the recent literature, the price elasticity of demand for SSBs, fast food, fruits and vegetables was estimated to be -1.21, -0.52, -0.49 and -0.48, respectively. The studies that linked soda taxes to weight outcomes showed minimal impacts on weight; however, they were based on existing state-level sales taxes that were relatively low. Higher fast-food prices were associated with lower weight outcomes particularly among adolescents, suggesting that raising prices would potentially impact weight outcomes. Lower fruit and vegetable prices were generally found to be associated with lower body weight outcomes among both low-income children and adults, suggesting that subsidies that would reduce the cost of fruits and vegetables for lower-socioeconomic populations may be effective in reducing obesity. Pricing instruments should continue to be considered and evaluated as potential policy instruments to address public health risks.
"Sugary drinks are the largest source of added sugars in the American diet (Reedy & Krebs-Smith, 2010; Welsh, Sharma, Grellinger, & Vos, 2011), responsible for up to 43% of the increase in caloric intake over the past generation (Woodward-Lopez, Kao, & Ritchie, 2010). While soda consumption has declined over the last fifteen years (Kit, Fakhouri, Park, Nielsen, & Ogden, 2013), consumption of other sugary beverages such as sports and energy drinks has risen (Han & Powell, 2013). Sugary beverages, and the marketing that promotes them, are also associated with substantial racial and ethnic health disparities. "
[Show abstract][Hide abstract] ABSTRACT: In 2012 and 2013, Richmond and El Monte, CA, and Telluride, CO, became the first communities in the country to vote on citywide sugary drink taxes. In the face of massive spending from the soda industry, all three proposals failed at the ballot box, but the vigorous public debates they inspired provide valuable insights for future policy efforts. We analyzed local and national news coverage of the three proposals and found that pro-tax arguments appeared most frequently in the news. Advocates for the taxes focused primarily on the potential community health benefits the taxes could produce and the health harms caused by sodas. Tax opponents capitalized on the existing political tensions in each community, including racial and ethnic divisions in Richmond, anti-government attitudes in El Monte, and a culture of individualism in Telluride. Pro-tax arguments came mainly from city officials and public health advocates, while anti-tax forces recruited a wide range of people to speak against the tax. The soda industry itself was conspicuously absent from news coverage. Instead, in each community, the industry funded anti-tax coalition groups, whose affiliation with industry was often not acknowledged in the news. Our analysis of this coverage exposes how soda tax opponents used strategies established by the tobacco industry to fight regulation. Despite these defeats, tax advocates can take inspiration from more mature public health campaigns, which indicate that such policies may take many years to gain traction.

"Third, our interest in peer effects in youths' eating habits is policy driven. There has been much discussion on implementing tax policies to address the problem of obesity (e.g., Caraher and Cowburn, 2007; Powell et al., 2013). As long as peer effects in fast food consumption is a source of externality that may stimulate overweight among adolescents, it may be justified to introduce a consumption tax on fast food. "
"All but one study found subsidies on healthier foods to significantly increase the purchase and consumption of promoted products . The seventh review  assessed the potential effectiveness of food and beverage taxes and subsidies for improving body weight outcomes. This review included 20 studies and found minimal impacts on weight due to soda taxes. "
[Show abstract][Hide abstract] ABSTRACT: Point-of-sale is a potentially important opportunity to promote healthy eating through nutrition education and environment modification. The aim of this review was to describe and review the evidence of effectiveness of various types of interventions that have been used at point-of-sale to encourage purchase and/or eating of healthier food and to improve health outcomes, and the extent to which effectiveness was related to intensity, duration and intervention setting.
Records from searches in databases were screened and assessed against inclusion criteria. Included studies had risk of bias assessed. Intervention effectiveness was assessed for two outcomes: i) purchase and/or intake of healthier food options and/or nutrient intake; and ii) mediating factors that might effect the primary outcome.
The search identified 5635 references. Thirty-two papers met the inclusion criteria. Twelve studies had low risk of bias and were classified as strong, nine were moderate and 11 were weak. Six intervention types and a range of different outcome measures were described in these papers: i) nutrition education and promotion alone through supermarkets/stores; ii) nutrition education plus enhanced availability of healthy food; iii) monetary incentive alone; iv) nutrition education plus monetary incentives; v) nutrition intervention through vending machines; and vi) nutrition intervention through shopping online. The evidence of this review indicates that monetary incentives offered to customers for a short-term look promising in increasing purchase of healthier food options when the intervention is applied by itself in stores or supermarkets. There was a lack of good quality studies addressing all other types of relevant point-of-sale interventions examining change in purchase and/or intake of healthier food options. There were few studies that examined mediating factors that might mediate the effect on the primary outcomes of relevant interventions.
A range of intervention types have been used at point-of-sale to encourage healthy purchasing and/or intake of healthier food options and to improve health outcomes. There is a need for more well designed studies on the effectiveness of a range of point-of-sale interventions to encourage healthier eating and improve health outcomes, and of the mediating factors that might impact these interventions.
