The impact of taxing sugar-sweetened beverages on health, body weight and consumption.


Sugar Sweetened Beverages (SSBs) are beverages that contain added sugar, corn syrup, or other caloric sweeteners, such as soda. Unlike other food and beverages, SSBs offer no nutritional value (1), and have been linked to increased risk of obesity, heart disease, hypertension, and diabetes (2 -7).

Recently, SSB taxes have emerged as a potential public health strategy to address obesity and diet-related chronic diseases. This brief summarizes findings from a number of reviews relevant to the impact of taxing or changing the price of SSBs on beverage consumption and body weight.

Key Findings

  • Taxing or raising the price of SSBs may effectively reduce SSB consumption (8-10).
  • Effectiveness of tax or price changes may be limited when they are applied only within specific settings, such as grocery stores or vending machines, as consumers have the ability to purchase these products at a lower price elsewhere (8).
  • Taxing SSBs may help to improve population-level body weight (8, 10). However, the impact will likely depend on the size and type of tax that is applied (10).
  • More research is needed to illustrate the link between taxation and price changes of SSBs, beverage consumption, and population body weight (8, 10).

To learn more about policies relevant to obesity prevention, we recommend visiting the Canadian Partnership Against Cancer (CPAC)’s Prevention Policies Directory.

The Directory is a freely-accessible online database of policies relating to cancer and chronic disease prevention, many of which address obesity prevention. It allows users to search by risk factor, jurisdiction, geographical location, and document type and provides summaries and direct access to policy documents.
