Why did the 7th U.S. Circuit Court of Appeals rule that Chobani must face the lawsuit over its 'Zero Sugar' yogurt claim?

The court ruled that consumers can pursue a class-action lawsuit because Chobani’s 'Chobani Zero Sugar' yogurt contains four grams per serving of allulose—a monosaccharide—and the FDA defines 'total sugars' to include all monosaccharides, not just glucose, fructose, lactose, and sucrose; Judge Thomas Kirsch found the FDA’s position 'thorough,' 'valid,' and consistent with prior agency statements, rejecting Chobani’s argument that allulose is exempt from the 'sugar' definition under the Nutrition Facts labeling rules.

What did the plaintiffs allege, and how did the court respond to Chobani’s claim that reasonable consumers wouldn’t be misled by the 'sugar free' label?

Plaintiffs James and Abigail Franco alleged they bought the yogurt in 2023 at a Chicago-area Costco and would not have done so—or would have paid less—had they known it contained four grams of allulose per serving; the court held that their allegation of being fooled by Chobani’s 'absolute promise' of 'sugar free' was not implausible, stating it did not matter whether 'reasonable consumers would care about allulose,' thereby allowing the case to proceed.
