That’s what scholars at Stanford University and University of California, San Francisco, concluded in an article in Health Affairs. The authors compare two policies: Banning the use of food stamps for the purchase of soda pop, or giving an extra subsidy of thirty cents on the dollar for the purchase of fruits and vegetables. They conclude that the ban on soda pop would have a greater impact on obesity:
A ban on sugar-sweetened beverage purchases would be expected to reduce kilocalorie intake from these beverages by a net average of 24.2 kcal per person per day among SNAP participants (95% CI: 22.8, 25.5) — a 15.4 percent decline in calorie consumption from sugar-sweetened beverages, according to our model.
Given this decline in net kilocalorie intake, overall obesity rates declined over the simulated period.
When accounting for baseline type 2 diabetes rate differences among cohorts, our model estimated that the largest type 2 diabetes incidence decline would be expected among adults ages 18–65…
