Not a fan of sushi, brussels sprouts, or any type of bread that's not white? You may not be just a picky eater—you may have an actual disorder, LiveScience reports. Researchers studying finicky adult eaters have identified a condition called "selective eating disorder," and they think people like 63-year-old Bob Krause may suffer from it. "If I could snap my fingers and change, I would," says Krause, who eats little other than peanut butter, crackers, grilled cheese sandwiches, and chocolate milk.
People like Krause avoid restaurants and social events that involve food, because there are so few foods they can eat; he says it contributed to the demise of his two marriages. They "aren't doing this just to be stubborn," says one of the researchers. Based on a survey of 7,500 people, researchers believe these people are suffering from a distinct condition, and have ruled out obsessive-compulsive disorder, anorexia, bulimia, and the like. They're not yet sure what causes the disorder, and don't know if the behavior can be changed—but they have noticed some similarities among the sufferers, who tend to avoid alcohol and fruit, and often list bacon as the only meat they will eat.
