Rob DeSalle, an evolutionary biologist at the American Museum of Natural History in New York, told American science website Gizmodo that eliminating the cravings for junk foods could take a while.

Health conditions associated with a poor diet mostly affect middle-aged adults, who have probably already had children and passed their genes on, he said.
