Americans will see food costs rise "tremendously" in the coming weeks, according to billionaire supermarket owner John Catsimatidis. Catsimatidis, who is the president of Gristedes and D'Agostino Foods, discussed his concerns about inflation and supply chain issues on FOX Business’ "Mornings with Maria," and warned companies like Nabisco, Pepsi and Coke will begin to prioritize products and raise prices in order to get ahead. "I see food prices going up tremendously," he told Maria Bartiromo.
