According to this study, Wholesome Foods and Wholesome Morals? Organic Foods Reduce Prosocial Behavior and Harshen Moral Judgments,
This study has been reported in various media including Does organic food make you a jerk?, Study Suggests that Eating Organic Foods Contributes to Moral Depravity, and Does organic food turn people into jerks?.Recent research has revealed that specific tastes can influence moral processing, with sweet tastes inducing prosocial behavior and disgusting tastes harshening moral judgments. Do similar effects apply to different food types (comfort foods, organic foods, etc.)? Although organic foods are often marketed with moral terms (e.g., Honest Tea, Purity Life, and Smart Balance), no research to date has investigated the extent to which exposure to organic foods influences moral judgments or behavior. After viewing a few organic foods, comfort foods, or control foods, participants who were exposed to organic foods volunteered significantly less time to help a needy stranger, and they judged moral transgressions significantly harsher than those who viewed nonorganic foods. These results suggest that exposure to organic foods may lead people to affirm their moral identities, which attenuates their desire to be altruistic.
It would seem, if this study is to believed, that perhaps organic food should be banned in order to prevent anti-social behavior, and heavily sugared and salted foods should be promoted in order to promote prosocial behavior.
Or is the study a piece of "scientific" nonsense? Really, exposure to organic foods influences moral judgements and behaviors?
