Does taxing sugary drinks result in better health outcomes? What some cities have found

“The overall effect of the [sweetened beverage] tax in Philly was a 35% reduction in sales of these taxed drinks….I’ve been working in this area for about 20 years. And I have never seen a behavioral effect that large,” Dr. Christina Roberto tells PBS.

“Eating behavior is so hard to change, let alone change it over the long term. And so to me, this is an incredible intervention to actually get people to stop or consume fewer of these drinks that we know are making us sick,” she says.
