Even if you’ve never counted a macro in your life, it’s hard to miss America’s protein obsession. Protein powders and shakes are old news — these days, brands are packing protein into just about everything you can imagine (chips, cookies, breakfast cereal, waffles, candy bars), and plenty you probably wouldn’t (pizza crust, soda, espresso martinis).
But what about foods like Greek yogurt that already have a lot of protein naturally? In the modern protein arms race, even that isn’t enough. Brands are still scrambling to squeeze out a few more grams on the label — and that’s exactly how one yogurt war ended up in federal court. We’ll strain the facts down to the basics.
A Very Thick Rivalry
Danone and Chobani are the heavyweights of the yogurt aisle, the names you’re most likely to see staring back at you from the Greek‑yogurt shelf in any big supermarket.
Danone sells several high‑protein yogurts under its Oikos brand. Oikos Pro is marketed as a high‑protein line, with servings labeled at 20 grams of protein or more, while Oikos Triple Zero is another Greek yogurt line from Danone that is also positioned as high‑protein but generally at a somewhat lower protein level than Oikos Pro.
Chobani sells a high‑protein Greek yogurt line under names including “20g Protein” and “High Protein Greek Yogurt,” and these products are labeled with “20g” in the name and 20 grams of protein per serving on the Nutrition Facts panel.
With such similar products and marketing, it’s no surprise that the rivalry runs deep … and that any perceived false claims about protein would really set off one of the players. So when Danone decided Chobani’s “20g Protein” tubs were basking in a fake protein halo, it turned to the law. It filed a complaint in federal court in New York, arguing that the way Chobani does the serving‑size math misleads shoppers and violates labeling rules.
But before getting into the weeds of Danone’s allegations, it helps to understand the basic rules for calculating those serving sizes and protein numbers.
FDA’s Rules of Food Math
The Food and Drug Administration is the federal agency that oversees how packaged foods are labeled, including their nutrition facts. It uses “reference amounts customarily consumed” (RACCs) to standardize serving sizes across foods.
For yogurt, the FDA says the RACC is 170 grams. When a package holds a lot more than that (like a big tub), manufacturers must base serving size on the 170‑gram RACC and express it using both a household measure (like ⅔ cup or ¾ cup) and the related gram weight, following FDA’s rounding and expression rules. That final gram number is what they use as the official serving size for all the per‑serving nutrition facts.
For smaller, single‑serve containers that hold less than twice the 170‑gram amount, the rules are simpler: the whole container counts as one serving, so the serving size is “1 container,” and the grams are just whatever the container actually holds.
Danone Says Chobani Doesn’t Hold Water
Danone’s legal theory centers around the fact that shoppers care a lot about protein and that “20 grams per serving” has become a magic number in the yogurt aisle. It says people treat that grams‑per‑serving figure as a shortcut for deciding whether a yogurt is truly “high protein.” From there, Danone claims that Oikos Pro has more protein per ounce than Chobani’s “20g Protein” yogurts, but that Chobani’s branding hides this by focusing on the “20g Protein” name and the 20‑gram number, not on how much yogurt you actually have to eat to get there.
Danone then zeroes in on serving‑size rules for big tubs. Using Chobani’s own label information (servings listed at three‑quarters of a cup, each serving weighing 190 grams, and 20 grams of protein per serving), it redoes the math under FDA’s serving‑size framework. Danone argues that if three‑quarters of a cup weighs 190 grams, the 170‑gram reference amount for yogurt corresponds to a smaller volume that should be rounded down to two‑thirds of a cup, not rounded up to three‑quarters. On that basis, it says the correct serving size would yield only about 18 grams of protein per serving, so the tubs should not be labeled as 20 grams per serving.
In Danone’s view, that means Chobani is overstating both serving size and per‑serving protein on its “20g Protein” tubs. Danone calls this misrepresentation and says it violates FDA serving‑size rules for multi‑serve products.
Is Danone Getting Skimmed?
How does this affect Danone, though? After all, it needs standing in order to bring a civil suit. Well, the yogurt company argues that its competitor’s inflated “20g” claim distorts competition. Danone says that while its own higher-priced product, Oikos Pro, truly delivers 20 grams or more of protein per serving and sits in an “ultra‑high‑protein” tier, a correctly labeled Chobani tub at 18 grams per serving would belong closer to Danone’s lower-priced product, Oikos Triple Zero. In other words, Chobani is getting away with selling products at a higher price point than competitors’ equivalent products, which harms Danone’s bottom line.
Legally, Danone wraps all of this into false or misleading claims under the federal Lanham Act. It also cites New York and California consumer‑protection laws that incorporate FDA labeling standards, along with a common‑law unfair‑competition claim. Whether that reading of “20g protein” and the serving‑size rules is right is what the court will eventually have to decide.
