The debate over whether Coca-Cola should use high-fructose corn syrup or cane sugar in its signature cola obscures an important fact: Consumers are increasingly looking for Coke with no sugar at all. Coca-Cola Zero Sugar, which was introduced in 2017, uses both the artificial sweetener aspartame and the natural sweetener stevia in its recipe. It's one of Coca-Cola's fastest-growing products. The scrutiny over Coke's sweeteners began Wednesday, when President Donald Trump announced that the Atlanta company had agreed to switch to using cane sugar in the version of its trademark beverage made in the U.S. Coca-Cola didn't confirm the change, but it defended high fructose corn syrup in a social media post on Thursday.
