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.

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.
