Danone’s latest lawsuit against Chobani highlights the risks and competitive advantage of protein claims in the modern consumer landscape.
In a complaint filed with a New York district court, Danone alleged that Chobani’s 20G line of potted yogurt is marketed as comparable in protein content to Danone’s Oikos Pro range – when in reality, Chobani’s product is less protein-dense ounce for ounce.
The issue is rooted in packaging formats. Danone noted that Chobani has strayed from the industry-standard 5.3oz single-serve format in favour of 6.7oz to reach the 20g protein threshold – meaning that 5.3oz of Chobani yogurt falls short on protein compared to other competitors.
The single-serve pots aren’t the legal problem, however. The alleged misrepresentation relates to newly-launched multi-serves, where ounce for ounce, Chobani’s yogurt only contains 18g of protein per serving instead of the stated 20g. And because multi-serve sizes are standardised in the US, the Greek yogurt brand cannot sell its product in larger pots to achieve 20g.
Danone argued that the de facto lower protein content means Chobani’s product shouldn’t be positioned alongside Danone’s premium-priced, ultra-high protein range. This has marketing but also operational and cost implications, as formulating and manufacturing high-protein yogurt requires significant R&D muscle.
“If the Chobani Product were truthfully named, labelled, and marketed, consumers would not see it as a viable alternative to Oikos Pro in the ultra-high-protein yogurt category,” Danone’s complaint reads. “However, Chobani’s deceptive conduct makes consumers perceive it as a legitimate alternative in that category – thereby siphoning away protein-conscious customers who would otherwise have purchased Oikos Pro.
“If it were truthfully named, labelled, and marketed, the Chobani Product’s closest comparator with respect to protein density would not be Oikos Pro, but Oikos Triple Zero – a different Danone US yogurt product that offers 15 to 18 grams of protein per serving (depending on variety) and costs significantly less than both the Chobani Product and Oikos Pro.”
Danone is seeking injunctive relief, damages, corrective advertising, and disgorgement of Chobani profits that’s resulted from shoppers buying its product instead of Danone’s.
This is the second active legal battle between the two dairy and nutrition majors, who are also at loggerheads over packaging claims in cold coffee.
‘Proteinmania’ intensifies
The lawsuit signals the increasingly central role of protein in the global food and beverage market.
For Danone in particular, protein has become a major profit driver in multiple regions. In North America, demand for its high-protein yogurts outpaced supply last year, contributing to sluggish performance in the region towards the end of 2025.
And more widely, demand for protein is only intensifying due to evolving consumer trends, including the increased uptake of weight management medications as well as policy changes.
According to Danone consumer research, the percentage of Americans who consciously incorporate protein in their diet has risen from 59% in 2022, to 70% in 2025, and was at 75% in late February 2026; with a high-protein diet being the most commonly-followed diet by Americans.
The new Dietary Guidelines for Americans recommend higher daily protein intake, which has also increased demand for foods that are high in protein but low in calories.
Meanwhile, 20g of protein has become a baseline for protein content among multiple categories, with high-protein claims attracting a price premium of around 12% according to Cobank research.
Ultimately, the case underscores how even small differences in formulation and labelling can carry outsized competitive and legal consequences.
