U.S. Researchers are now suggesting that people constantly exposed to pictures of foods, say on their social media sites, are likely to view their own food as much less appetizing, according to a report by UPI. Co-authors of the study - Ryan Elder and Jeff Larson, both marketing professors in Brigham Young University’s Marriott School of Management, have observed that people whose friends are constantly posting photos of their favorite foods on Facebook, Pinterest, etc, are having their own appetites ruined by the overexposure.
232 participants were asked to view and rate pictures of different foods. In one study 60 were asked to rate sweet foods, such as cake, pies, chocolates and the like. Another 60 were asked to rate salty foods, such as chips, peanuts, French fries, etc. After rating each photo, the participant was asked to eat salty peanuts, and then rate how much they had enjoyed them. Results showed that people did not the peanuts enjoyable, despite the fact that peanuts had not been one of the foods viewed.
Elder and Larson said that an overexposure to food imagery increased people's satiation. Satiation was defined as the drop in enjoyment with repeated consumption – or the subsequent bites of cake were less enjoyable than the first. The findings were published in the Journal of Consumer Psychology.
