Sugar-sweetened beverages (SSBs) are a major contributor to the development of diabetes and cardiovascular disease, the number one cause of death globally. SSB taxes pose an important policy approach to reducing diet-related disease.

Research Brief: Sugar-sweetened beverage consumption declined among 7-10th grade students in San Francisco, California, from 2015-2019

Sugar sweetened beverages (SSBs) contribute to diet-related disease, and SSB consumption is higher among youth than adults. The city of San Francisco, CA passed a slate of policies aiming to reduce SSB consumption between 2014-2018; as such policies are passed, it is important to monitor local trends in SSB consumption. Using a repeated cross-sectional study design, we examined trends in SSB consumption among middle and high school students in San Francisco from 2015-2019.

UC Center Sacramento Presentation

Why Soda Taxes Can Address Pandemics and Direct Public Dollars to Equity

On September 30, 2020, Dr. Kristine Madsen presented the most recent evidence on the impact of SSB taxes on public health and how such taxes can save billions of dollars in health-care spending. She shared new research documenting how revenues from soda taxes in the U.S. are being used, including how they have supported a rapid response to the COVID-19 crisis. She also discussed the potential impacts of these revenues being invested in historically disenfranchised neighborhoods and communities.

Infographic – SSBs and Tooth Decay

We already know that sugary drinks kill thousands across the globe each year in part by contributing to diabetes and obesity. But soda consumption also causes tooth decay, the #1 most prevalent disease in the world. Unlike diabetes and obesity, tooth decay can occur within a matter of months, especially in young children. Tooth decay affects nearly everyone, but is especially prevalent in low-income areas and among people with high sugar consumption and low access to fluoride.
