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.

PepsiCo wants to follow the lead of customers on its journey to "eliminate artificial colors and artificial flavors," the company's CEO said Thursday.

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.
