CHICAGO — A judge for the US District Court, Northern District of Illinois on May 29 dismissed a class-action lawsuit against Chobani. The plaintiffs filed the lawsuit in May of 2023, arguing the company misled consumers with the product name Chobani Zero Sugar yogurt because it contains 4 grams of allulose, a monosaccharide with a chemical composition nearly identical to the composition of fructose and thus a sugar.

Consumers were “tricked” into buying “deceptively labeled” yogurt, according to the lawsuit brought by four consumers: Jason Franco, Abigail Franco, Misty M. Lacy and John D. Baker.

Both the plaintiffs and New York-based Chobani agreed that allulose is a monosaccharide, but Chobani pointed to the US Food and Drug Administration’s stance on allulose. The FDA in April of 2019 said companies can exclude allulose from the total sugars and added sugars found on the Nutrition Facts Labels of products. Allulose differs from other sugars in how it is metabolized, according to the FDA, and it does not meaningfully increase blood glucose or insulin or promote cavities.
