Ten months after the University of California, San Francisco, banned sales of soda and other sugar-sweetened drinks, 214 full-time employees who had frequently consumed these beverages were drinking only about half as much of them, on average, according to a study in JAMA Internal Medicine. The research also showed a drop in waist circumference among the employees.

These results are promising because they indicate that an environmental change, in this case limiting access to sugary drinks in the workplace, can help people make wiser dietary choices over the long run and can potentially improve employee health. Plus, this type of policy may be less controversial than a soda tax.
