Chobani class action lawsuit overview:

Who: Plaintiff Hale Knox filed a class action lawsuit against Chobani LLC.
Why: Knox claims Chobani misrepresents the protein content in its “20G Protein” yogurt line.
Where: The Chobani class action lawsuit was filed in New York federal court.

A new class action lawsuit alleges Chobani misrepresents the protein content in a line of its yogurt products.

Plaintiff Hale Knox claims Chobani’s “20G Protein” yogurt line exaggerates the actual protein per serving, which, in turn, violates the U.S. Food and Drug Administration (FDA) regulations and deceives health-conscious consumers.

“Chobani knows consumers are mindful of the amount and number of grams of protein they consume per serving and that protein content is a material driver in the purchase of yogurt products promoting protein,” the Chobani class action lawsuit says.

Knox argues that while Chobani advertises 20 grams of protein per serving, the actual content is significantly less when calculated according to FDA guidelines.

The plaintiff wants to represent a nationwide class and New York class of all persons who purchased Chobani’s 32-ounce 20G Protein yogurt products for personal use and not resale.

Chobani allegedly inflates serving sizes with multiple-serving containers

Knox claims that Chobani’s single-serving yogurt containers are designed to hold 6.7 ounces, slightly more than the industry standard of 5.3 ounces, to reach the 20-gram protein threshold.

However, Knox argues Chobani’s multiple-serving containers inflate serving sizes without increasing the actual yogurt content, resulting in misleading protein claims.

Knox explains that if the 32-ounce product were labeled in accordance with FDA serving-size regulations, it would have a serving size of one-half cup and contain about 18 grams of protein per serving, rather than the advertised 20 grams.

“Chobani engages in this conduct with full knowledge that consumers want to consume more protein but have substantial ‘gaps’ in nutritional understanding – such that they are likely to be fooled by Chobani’s ploy,” the Chobani class action lawsuit says.

Further, Knox argues Chobani’s alleged misleading labeling has allowed the company to charge a premium for its yogurt, capitalizing on consumers’ willingness to pay more for high-protein products.

Knox claims Chobani is guilty of unjust enrichment and violation of New York General Business Law. He demands a jury trial and requests declaratory and injunctive relief and an award of actual, punitive and statutory damages for himself and all class members.

In another recent yogurt-related complaint, a consumer filed a class action lawsuit against Target earlier this year over claims the company falsely markets certain snacks as “yogurt covered.”
