San Francisco, led by City Attorney David Chiu, filed a landmark lawsuit in early December 2025 against 10 major ultra-processed food (UPF) manufacturers (like Coca-Cola, PepsiCo, General Mills, Nestlé, Kraft Heinz) for deceptive marketing, claiming they knowingly engineered addictive products, especially targeting children, and created a public health crisis linked to diseases like diabetes and cancer, seeking financial penalties and changes to marketing practices.
This first-of-its-kind suit argues these companies violate California laws by hiding health risks, similar to tobacco litigation.

    Kraft Heinz Company
    Mondelez International (maker of Oreos, Sour Patch Kids)
    Post Holdings
    The Coca-Cola Company
    PepsiCo
    General Mills (maker of Cheerios)
    Nestle USA (maker of Kit Kat)
    Kellogg (now WK Kellogg)
