Abstract

Purpose of Review

Interest in taxes on unhealthy foods and beverages as a public health tool has increased in recent years. This paper aimed to summarise recent evidence of the impact of taxes on unhealthy foods and beverages on food purchases, and discuss opportunities to advance knowledge and policy impact.

Recent Findings

Evaluations of taxes on unhealthy foods and beverages have shown reductions in purchases of targeted unhealthy products and nutrients. Similarly, data from multiple sources demonstrate that as prices of unhealthy foods and beverages increase, purchase volume decreases. However, studies indicate potential for substitution to non-taxed unhealthy foods, which needs to be factored into taxation design.

Summary

Taxes on unhealthy foods and beverages are a promising strategy to improve population diets. Further research is required to understand food industry responses to tax implementation, as well as the impact of taxes on population and planetary health outcomes.
