President Donald Trump said Wednesday that Coca-Cola has agreed to use real cane sugar in Coke beverages distributed in the U.S. at his suggestion. Trump wrote on his social media site that cane sugar is “better” than high fructose corn syrup, which the company currently uses in its flagship soft drink. Coca-Cola didn’t confirm the change. In a statement, the company said it appreciated Trump’s enthusiasm and would share details on new offerings soon. The move was met with skepticism from nutritionists, who say there’s very little difference between traditional sugar and the cord-derived sweetener found in many American foods. “For all practical purposes, they're the same, so I find the switch to be nutritionally hilarious,” said Marion Nestle, New York University nutrition and food studies professor emerita. High fructose corn syrup has long had an association with unhealthy foods. Nestle says that’s because it was introduced at a time when traditional sugar was more expensive. “We like sweet foods a lot. So the more high fructose corn syrup that got dumped into foods, the more people like them and bought them,” she said. Nestle, who’s not related to the Swiss food company (and name is pronounced like placing two objects together), says now that costs are comparable, more producers are looking at cane and beet sugar alternatives. Trump’s Health Secretary Robert F. Kennedy, whose nutrition views often diverge from mainstream nutrition science, has spoken out against sugar–going so far as to call it “poison.” The debate over whether Coca-Cola should use high-fructose corn syrup or cane sugar in its signature soda obscures an important fact: Consumers are increasingly looking for Coke with no sugar at all. Coca-Cola Zero Sugar, which was introduced in 2017, uses both the artificial sweetener aspartame and the natural sweetener stevia in its recipe. It’s one of Coke’s fastest-growing products, with global case volumes up 14% in the first quarter of the year. By comparison, the company’s total case volumes were up 2%. PepsiCo also noted Thursday that 60% of its sales volumes in major markets in the second quarter came from low- or no-sugar drinks.
