The scrutiny over Coke’s sweeteners began Wednesday, when President Donald Trump announced that Atlanta-based Coca-Cola Co. had agreed to switch to using cane sugar in the regular version of its beverage manufactured in the U.S.

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.

A possible move by Coca-Cola , and other beverage and food industries, to use cane sugar instead of corn syrup as a sweetener would be difficult and expensive to implement, while mostly negative for farmers in the United States.
