Subconscious “Stop Signs” Curtail Consumption Of Potato Chips In Tubes

Researchers at Cornell University have found that placing edible serving-size markers in tubes of potato chips can help curb overeating. The researchers conducted an experiment in which 96 students divided into two groups were served potato chips in tubes while watching videos in class. Some of the tubes contained chips dyed red. The students who were served tubes with chips dyed red ate 50 percent less than their peers. The researchers concluded that the red chips acted as unconscious “stop signs” that cut the number of chips consumed.
