SAN FRANCISCO – A newly crafted wellness policy in the San Francisco Unified School District forbids schools from selling or serving any type of sweetened beverages, and includes plans to phase out chocolate milk.

The district’s board of education approved a wellness policy April 28 that prohibits sales of beverages with added sweetener for everyone in the district, including staff, parents or volunteers, BeyondChron.org reports.

The policy means all soft drinks, even diet soda, cannot be sold on any San Francisco school campus, and aims to eliminate chocolate milk eventually.

“The District’s nutrition guidelines shall apply to all foods and beverages sold or served to students, staff and families on every PreK-12 campus and administrative building, including but not limited to: snacks; rewards; celebrations; school meals; a la carte service in the cafeteria; vending machines; donated food; school stores; snack bars/concession stands; fundraisers on school grounds; classroom-based activities; staff and parent meetings; and after school programs,” according to the new policy.

“(Student Nutrition Services) will explore ways to phase out chocolate milk and will share findings from its exploration with the Board of Education within a year after the Policy is approved.”

SFUSD board member Jill Wynns believes the changes were a long time coming, and she thinks it’s necessary that the new rules apply to everyone, not just students, according to the news site.

“As school leaders, we have talked the talk about wellness for a long time, including about making smart choices in food and drinks. This policy reminds us that we also need to walk the walk,” Wynns said. “It’s important for all adults at school to model healthy behaviors, and we should be willing to abide by the same rules we put in place for students. That’s how you build a healthy community.”

In other words, board members’ free pre-meeting meals will now fit within the nutrition guidelines, which are significantly stricter than the most recent federal wave of school food restrictions imposed on schools through the Healthy and Hunger Free Kids Act.

That Act is the brainchild of first lady Michelle Obama, and is designed to fight childhood obesity with bureaucracy.

BeyondChron reports SFUSD’s policy applies to all school food and beverages, including breakfast. Currently, the SF Food Bank serves a morning snack to about 11,000 mostly low-income students at about 30 SFUSD schools, but will now have to gain permission to continue its quest to ensure students don’t go hungry.

“Another section of the policy seeks to protect the breakfast effort from unwanted competition,” according to the news site. “Schools are prohibited from allowing outside organizations to sell or serve even policy-compliant food and beverages to students if it is in competition with school meals, and requires any such group to get prior approval from the district’s Student Nutrition Services department.”

“Some feel that the (SF Food Bank) morning snack conflicts with school breakfast, especially Second Chance Breakfast, as both are offered during morning recess. SFUSD’s Orla O’Keeffe confirmed that the Food Bank will need to obtain permission from SNS to continue serving snacks at school.”

Marion Nestle, a “food policy expert” and New York University professor, seemed quite excited that SFUSD is banning all sugar drinks throughout the district.

“This is huge. It sends a clear message that sugary drink are inappropriate in schools,” Nestle told the news site. “They don’t aid learning, have no nutritional value, and school kids don’t need liquid candy.

“Congratulations to the SFUSD for great courage and good common sense,” she said.
