Consumers file a proposed class action against Starbucks, alleging the company falsely advertises eight protein beverages as “sugar-free.” The lawsuit claims the drinks contain 13 to 21 grams of sugar per serving, including lactose, a naturally occurring sugar found in milk. The complaint focuses on “venti” size servings of 20 or 24 ounces.

The outlets report that the plaintiffs argue U.S. federal standards prohibit using the term “sugar-free” for products that exceed 0.5 grams of sugar per 12-ounce serving. They also say Starbucks did not include required federal disclaimers that the protein beverages are not low-calorie foods or intended for weight control. Reported motivations include consumers’ desire to reduce sugar intake.

Across coverage, the core allegation is consistent: the “sugar-free” label conflicts with the sugar content stated in the complaint. Investing.com, Quartz, BNN Bloomberg, and Korea Times describe the suit as a consumer challenge to marketing claims, while a Starbucks spokesperson responds that the lawsuit’s claims lack merit and that the company provides nutrition and related information across its materials.
