Adherence
Implementing a sugar-sweetened beverage (SSB) excise tax significantly reduces SSB consumption and increases water consumption in low-income neighborhoods.
If you live in a city with an SSB tax, expect to drink less sugary soda and more water. The tax makes sugary drinks more expensive, which encourages healthier choices. The revenue from the tax is often used to fund public health programs, which can benefit your community.
GoodSupportsHIGH confidence
Consumption of SSBs decreased 21% in Berkeley and increased 4% in comparison cities (P = .046). Water consumption increased more in Berkeley (+63%) than in comparison cities (+19%; P < .01).
Why this rating
The study uses a robust difference-in-differences design with comparison cities, but relies on self-reported consumption data.
