Sugar-sweetened beverages, SSBs, contain added sugar, or in some cases, noncaloric sweeteners, and are nonalcoholic. As global waistlines have increased, so have taxes on these “bad boy” products – now implemented in “45 countries, including numerous subnational local jurisdictions.” A systematic review considers the impact of these taxes on raising revenue and improving health.
There is no doubt that raising the price of sugary beverages by increasing the tax reduces consumption. A new study once again looks at how price impacts demand. Whether this reduction in consumption has the desired outcome of improving health remains unknown and frankly unstudied.
