Why did San Francisco propose health warning labels for soft drinks?

San Francisco proposed health warning labels for soft drinks in 2015 to address the significant public health risks associated with their regular consumption.1

These concerns are rooted in the link between sugar-sweetened beverages and various chronic conditions, including obesity, type 2 diabetes, metabolic syndrome, and coronary heart disease. Because many soft drinks contain high levels of sugar—often exceeding recommended daily intake limits in a single serving—and contribute to tooth decay due to their acidity and chemical composition, the city sought to implement labeling requirements similar to those already mandated for tobacco and alcohol products.1

This initiative was part of a broader movement to use regulatory measures, such as taxes and warning labels, to combat the negative health impacts of sugary drinks and promote better public health outcomes.1
