Exposure to Conflicting News About The Health Benefits of Certain Foods

Exposure to conflicting news about the health benefits of certain foods, vitamins and supplements often results in confusion and backlash against nutrition recommendations, finds a recent study in the Journal of Health Communication: International Perspectives.

This confusion and backlash may make people more likely to ignore not only the contradictory information, but also widely accepted nutritional advice such as eating plenty of fruits and vegetables and exercising regularly, said Rebekah Nagler, Ph.D., assistant professor in University of Minnesota's School of Journalism and Mass Communication in Minneapolis and author of the study.

Nagler analyzed responses collected from 631 adults who took part in the Annenberg National Health Communication Survey in 2010. Participants were asked how much conflicting or contradictory information they heard from the media, including newspapers, television, radio, and the internet about four specific nutritional topics: red wine or other alcohol; fish; coffee; and vitamins or other supplements.

More than 71 percent of people surveyed said that they heard moderate or high levels of contradictory information about nutrition. Those with the greatest exposure to contradictory information expressed the most confusion about nutrition. Greater confusion was associated indirectly with backlash against nutritional advice in general, as indicated by agreement with statements such as "Dietary recommendations should be taken with a grain of salt," or "Scientists really don't know what foods are good for you". This was true even when controlling for age, education or level of general mistrust. Confusion and backlash were also slightly associated with less intention to exercise or eat fruits and vegetables.
