Starbucks sued over 'sugar-free' claims for protein beverages
Tap title to read story
Starbucks faces a proposed class-action lawsuit filed in federal court alleging the coffee chain falsely advertised eight protein beverages as sugar-free. Plaintiffs claim that despite online statements of no added sugar, venti servings contain significant natural sugar from lactose and exceed federal limits for sugar-free claims. The beverages, launched in September 2025 during menu updates, include vanilla and caramel protein lattes and matchas. Consumers argue the marketing exploits public demand for reduced sugar without providing mandated weight control disclaimers. Starbucks has defended its marketing practices, stating intent to vigorously fight the lawsuit regarding its nutritional labeling disclosures.
