Lawsuit claims Starbucks ‘sugar-free’ protein drinks contain up to 21 grams of sugar

SEATTLE — Three Starbucks customers have filed a proposed class-action lawsuit alleging the Seattle-based company misleads consumers by calling eight protein beverages “sugar-free” even though they contain 13 to 21 grams of sugar in a venti serving.

The complaint was filed Friday, Oct. 2 in U.S. District Court for the Western District of Washington in Seattle by Michael Walsh, Anne Legnini and Elna Potter, who are seeking to represent customers nationwide.
