Tax junk food, subsidize veggies: will it work?
NCT ID NCT07593937
First seen Jun 24, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study will test whether adding taxes to unhealthy foods and giving discounts on healthy foods changes what people buy in an online grocery store. About 2,239 adults from all income levels will participate, with some getting only taxes, some only subsidies, some both, and a control group with no price changes. The goal is to see if these policies improve the overall nutritional quality of purchases, especially for lower-income households.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Taxation on unhealthy foods and subsidies for healthy foods
What this could lead to
If successful, this could show that combining taxes and subsidies improves diet quality and reduces health inequalities, guiding future food policies.
What could go wrong
This is an online shopping simulation, not real-world behavior, and results may not translate to actual purchases or long-term habits. The study is not yet recruiting.
