How natural, exactly?

SAN DIEGO — Chobani will face some false advertising claims brought by consumers who say the company misrepresents the ingredients in its Greek yogurt products. The packaging says the products are made with “only natural ingredients,” but consumers say its inclusion of artificial coloring, stevia leaf extract, monk fruit extract and manufactured citric acid render the claim false. A California federal court allowed their claims about the extracts and acid to proceed, but dismissed the claim centered on food coloring.
