Adherence
Food pricing strategies, specifically taxes on unhealthy foods and subsidies for healthy foods, effectively alter consumption, with stronger effects on lower-income populations.
To improve diet at scale, use financial incentives. Subsidize healthy options (like fruits/veg) to make them cheaper, and tax unhealthy options (like sugary drinks) to make them more expensive. This works best when targeted at lower-income groups who are more price-sensitive.
a 10 % price reduction or subsidy increases consumption of healthful foods/beverages by 14 %, while a 10 % price increase or tax reduces consumption of unhealthful foods/beverages by 7 % decrease
Why this rating
Strong evidence from meta-analyses of modeling and prospective studies, including real-world tax implementation data.
