Does Coca-Cola made with cane sugar — aka Mexican Coke — really taste better than the U.S. version made with high-fructose corn syrup, as President Donald Trump claims? Not quite, according to some studies.

Asked about the switch, a representative for Coca-Cola didn’ explicitly say it would use cane sugar for products in the U.S.

President Donald Trump said Wednesday that Coca-Cola has agreed to use real cane sugar in its flagship soft drink in the U.S. at his suggestion — though the company didn’t confirm such a move.
