Starbucks faces a proposed class-action lawsuit alleging that the company misled consumers by marketing eight of its protein beverages as “sugar-free” despite containing lactose, a naturally occurring sugar found in milk. The suit, filed in federal court in Seattle, contends that the drinks contain between 13 and 21 grams of sugar per 20- or 24-ounce “venti” serving, contrary to consumer expectations for sugar-free products.

According to the complaint, federal regulations prohibit the use of “sugar-free” labeling on beverages that contain more than 0.5 grams of sugar per 12-ounce serving. The plaintiffs argue that Starbucks’ labeling violates these standards and aims to take advantage of the growing consumer demand to reduce or eliminate sugar intake. The lawsuit emphasizes that approximately 75% of Americans are actively trying to cut down on sugar consumption, suggesting that Starbucks’ marketing could mislead a significant portion of its customer base.

The complaint seeks unspecified damages for what it characterizes as false advertising. Starbucks has responded to the allegations by stating that the claims lack merit.

The case highlights ongoing scrutiny over product labeling and transparency in the food and beverage industry, particularly regarding health-related claims that may influence consumer choices. The litigation is pending in Seattle federal court.
