A new estimate of the health impact of soda taxes in Mexico sheds some light on what’s at stake in ballot measures coming to a vote in three Bay-area cities and Boulder, Colo. next week. In cases of heart disease and diabetes averted, the model suggests that, in Mexico, those levies are on track to save close to a billion dollars and powerfully improve lives. After a tandem run-up in consumption of sugar-sweetened beverages and obesity, Mexico has become one of the fattest countries on Earth. In 2014, it adopted a 10% excise tax on the sale of sugary drinks. (Healy, 11/3)

Can public health officials force Americans to break their soda habit? The answer may come soon from the University of California, San Francisco, a health sciences center that has more than 24,000 employees on its sprawling campus. Last year, U.C.S.F. removed sugar-sweetened beverages from every store, food truck and vending machine on its campus. Even popular fast-food chains on the campus, like Subway and Panda Express, have stopped selling Sprite, Coca-Cola and their sugary brethren at the university’s request. (O'Connor, 11/3)
