President Trump has a famous affinity for Diet Coke, which uses aspartame, a low-calorie artificial sweetener. He has reinstalled a button on the Oval Office desk that alerts White House staff when he wants a fresh can of Diet Coke.

Coke joins PepsiCo, Kraft Heinz and dozens of other big US companies that have pledged to remove artificial ingredients after Trump administration pressure.

Is Coca-Cola changing the recipe for its flagship soda? President Trump announced earlier this week that the company agreed to switch a primary ingredient for its U.S. beverages, but Coca-Cola hasn't yet confirmed that.

Coca-Cola typically sweetens its signature drink with corn syrup for the United States market and uses cane sugar in Mexico and some European countries, selling the cane sugar beverage as the imported "Mexican Coke" in the U.S. The U.S. cane sugar option will be added to the company's existing U.S. product line.
