Starbucks is currently facing legal action concerning its “sugar-free” protein drinks, with consumers claiming that some options contain sugar levels comparable to a candy bar. The lawsuit, which seeks class-action status, was filed in a Washington state federal court on October 2. It challenges eight of Starbucks’ hot and iced protein beverages, including the Sugar-Free Vanilla Protein Latte, Sugar-Free Caramel Protein Latte, and protein matcha drinks.
The lawsuit states that these beverages carry between 13 and 21 grams of sugar in a venti-sized serving. The plaintiffs argue that consumers would not reasonably expect such amounts of sugar in drinks marketed as “sugar-free.” The suit, initiated by three customers from California, New York, and Washington, aims to prevent Starbucks from labeling products as “sugar-free” if they contain sugar.
Starbucks is contesting these claims, maintaining that they lack merit.
A Starbucks spokesperson confirmed to Fox News Digital that the company provides comprehensive information about its protein beverages, sugar-free options, and nutritional content through various platforms, including menus, marketing materials, and its website. They assert that the sugar in these drinks comes from naturally occurring lactose in protein-boosted milk, not added sugars, and flavor is enhanced using sugar-free syrups.
Nicolette Pace, a registered dietitian and diabetes educator, explained that lactose, a natural sugar found in milk, isn’t classified as added sugar. However, she emphasized a distinction between “sugar-free” and “no added sugar.” Dr. Michael Aziz, an internist, added that “sugar-free” products must generally contain less than 0.5 grams of sugar per serving, according to FDA standards.
The lawsuit argues that Starbucks’ sugar-free labeled drinks, which reportedly contain 13 to 21 grams of sugar, mislead consumers. Attorney Danny Karon, though not involved in the case, mentioned that consumers might have paid a premium based on these misrepresentations. The challenge for plaintiffs will involve convincing the court and jury that they relied on Starbucks’ alleged false claims when purchasing.
Besides the drinks cited in the lawsuit, experts caution that many Starbucks specialty beverages contain significant sugar levels. For example, a venti Java Chip Frappuccino has nearly 80 grams of sugar, around 20 teaspoons. Similarly, other drinks, such as the Caramel Ribbon Crunch Frappuccino and seasonal favorites like Peppermint Mocha and Pumpkin Spice Latte, may boast high sugar content depending on size and customizations.
Dr. Aziz highlights the drastic nature of these sugar amounts, comparing them to the 63 grams in a standard 20-ounce soda. Pace advises that portion size plays a crucial role at Starbucks. The American Heart Association recommends women limit their added sugar intake to about 6 teaspoons (25 grams) per day, and men to 9 teaspoons (36 grams).
Pace suggests consumers simplify orders and opt for smaller sizes to reduce sugar consumption. Dr. Aziz recommends enjoying simpler options, such as a latte or cappuccino, for a more moderate treat.
