The evidence—and acceptability—of taxes on unhealthy foods

The global obesity pandemic has public advocates and policymakers grappling with the question of how best to respond. Among the various policy options, unhealthy food and beverage taxes have gained attention as a potentially effective intervention to reduce non-nutritive caloric intake, while raising government funds for health promotion programs at the community level. Yet in many countries, including in Israel, such proposals have not gained broad support. Cities in both United States and Mexico have found that taxes on sugar-sweetened beverages reduce consumption. Yet the food industry has successfully fought many such policies. Looking forward, those supporting taxation policies will need to provide clear evidence, a compelling use of funds raised, a convincing answer to industry claims, and attention to equity in implementation. With no easy fixes in sight to obesity, it is likely that taxes will remain viable – if contested – options for the foreseeable future.
