McDonald's disappointing July sales are just another indication consumers have lost their appetite for fast food, preferring to gobble up natural and organic foods instead, CNBC's Jim Cramer said Friday.
"There's just a sense around the globe that this good-tasting food is bad for you," Cramer said on "Squawk on the Street." "People are getting wise to McDonald's. They don't want to eat there globally."
Indeed, McDonald's reported July sales that were much worse than analysts had expected.
The fast food giant reported global same-store sales fell 2.5 percent, compared with the 1.1 percent drop forecast by Consensus Metrix. Same-store sales in the U.S. sank 3.2 percent, weaker than the 2.6 percent expected.
Cramer also knocked McDonald's for its low dividend yield. (Click here for the latest quote.)
"McDonald's is like a junk bond. How about that?" he said. "Junk food, junk bond."
Rival Yum Brands—which operates KFC, Pizza Hut and Taco Bell—will likely report "really hideous" earnings, too, Cramer said.
"When I look at McDonald's and when I look at Yum, what I think of is processed food," Cramer said. "This is not a good trend and I think all of our food companies have to accept the fact that you have to go WhiteWave."
To Cramer, WhiteWave Foods is "the anti-McDonald's." The company makes plant-based foods and beverages, as well as organic greens and produce.
"Plant-based foods are really front and center."
