SAN FRANCISCO – Students and faculty at the University of California, San Francisco can kiss their sweet drinks goodbye.

Public health researchers at the school convinced all vendors on campus to discontinue sales of any beverages with added sugar, including pop, fancy coffee drinks, milkshakes, and any juice with fructose, which is most, CNN reports.

“It’s a sales ban, which means the university has opted out of the business of selling and profiting off of sugar-sweetened beverages,” Laura Schmidt, professor in the School of Medicine, told the news site.

Schmidt told the site the ban went into effect last summer, but took a lot of convincing to get all vendors on campus to comply.

“It’s a very, very big institution,” she said.

The move means there is no longer any place on campus to buy sugar-added beverages, but it doesn’t prohibit students from bringing their own drinks to school. The university’s vendors still sell 100 percent fruit juice, diet drinks and zero-calorie pop because Schmidt said they’re effective replacements for those with sugar cravings, and there’s not enough science to ban them … yet.

Schmidt told CNN she’s among a group of researchers at the school known as SugarScience who have studied research on the health impacts of added sugar over the last two years. And although there’s no science that shows a policy banning those beverages is effective, they pushed for it anyway.

Now, the researchers are studying 2,500 university employees, including 214 self-identified heavy consumers of sugary drinks, to determine “if we can actually move the dial by using a workplace policy,” Schmidt said.

CNN reports:

For this smaller group, the researchers performed a complete physical, including weight, height and blood pressure measurements. Blood tests were performed as well. These employees returned for a physical six months after the sales ban began and once again at 12 months.

“We’re in the process of analyzing that data right now,” Schmidt said, though she said that after six months, a 25% decline in consumption had occurred among those who drank the most sugary beverages.

She is eager to see the latest results, noting that if she and her crew can show changes in consumption sustained over a year, “you know you’re making an impact.”

The sugar drink ban follows the federal government’s move to ban sugary drinks from all public schools that participate in the National School Lunch Program and rely on federal subsidies for needy students. Changes implemented in recent years have put restrictions on calories, fat, sugar, sodium, whole grains, fruits and vegetables for students in K-12 public schools at the urging of first lady Michelle Obama.

The changes resulted in plummeting school food and vending machine revenues to the point that the lost revenue exceeded their federal subsidies, forcing hundreds of schools to drop out of the National School Lunch Program entirely to salvage their food programs and serve students items they’ll actually consume, EAGnews reports.

CNN points out that New York City attempted to implement a similar sugary drink ban in 2012, but an appeals court found the regulation to be “arbitrary and capricious” and the board of health “failed to act within the bounds of its lawfully delegated authority.”

The legal challenge is unlikely at UCSF because all vendors voluntarily complied with the ban, Schmidt said, according to Fox 6.

Schmidt, who believes “our current food environment is rigged to make the unhealthy choice the easy choice,” contends that the ban has not impacted beverage sales on campus because vendors continue to stock non-sugary drinks.

“Everyone was worried they’d lose money, but no one lost money,” she said.

“The shelves are filled with stuff,” she said.  “It’s just stuff that isn’t loaded with sugar.”
