Chobani sued by Danone over high-protein yogurt claims

Food Dive reported the development on 2026-06-16. The Oikos maker said its rival is engaging in “unfair competition and consumer deception” to make its product more appealing to shoppers.

The report places the news in a wider commercial context. Danone sued Chobani, alleging its archrival is misleading consumers over how much protein is included in a serving of its high-protein yogurt. The food giant said on Monday that Chobani is manipulating the serving size on its 32-ounce containers of Chobani 20G Protein to inflate the protein content. Danone alleges that in order to claim 20 grams of protein per serving, Chobani sets its serving size.

For the food sector, the practical implications extend beyond the immediate announcement. The inflated serving size is found in Chobani's single-serve yogurt cups and the 32-ounce multiserve tubs, according to Danone. However, the lawsuit said that unlike single-serving containers, multiple-serving containers are subject to FDA rules governing the calculation of serving sizes.

Attention now turns to how companies, customers and regulators respond. Danone argues that changes to serving size lead shoppers into thinking that Chobani's yogurt has a similar amount of protein as Danone’s Oikos Pro, the company's ultra-high protein line. Instead of developing a product of comparable protein density, Danone said Chobani “chose to engage in unfair competition and consumer deception.”.
