Asked about the switch, a representative for Coca-Cola didn’t explicitly say it would use cane sugar for products in the U.S.

The president’s comment about Coca-Cola switching a key ingredient comes at a time when the US health secretary has criticized the use of ingredients like corn syrup.

Coca-Cola already produces its eponymous drink with cane sugar outside the U.S., most notably in Mexico, where it's sold in glass bottles. But in the U.S., the soda is made with high-fructose corn syrup, according to Coca-Cola's website.
