Public health researchers agree: The evidence is clear that people consume way too much sugar, that sugar contributes to weight gain, and that rising rates of obesity in the U.S. will lead to significant health problems in the future.

What’s much less clear is what to do about it. In this special, first-ever two-part episode of Gastropod, we tell the story of how sugary beverages — soda in particular — became Public Health Enemy Number 1.

Why are politicians and scientists targeting soda? Why have most attempts to pass soda taxes failed? And do these taxes even work to reduce consumption and obesity?
