Sharing a meal with your old flame? Watch out! Even a casual meal with your ex romantic partner will make your current partner very, very jealous because that's how important food is, to human beings.
Sharing a meal with a former romantic partner is more likely than other, non-food-related activities to make your current partner jealous, according to a study published July 11 in the open access journal PLoS ONE.
The authors, led by Kevin Kniffin of Cornell University, asked undergraduate students to rate their jealousy in response to hypothetical scenarios involving their romantic partner engaging with a former partner, either by email, phone, coffee, or a meal. They found that a meal elicited the highest jealousy ratings, potentially pointing to the importance of meals for human relationships and intimacy. Interestingly, the researchers did not find any significant differences in the jealousy reported by male versus female participants.
Dr. Kniffin remarks, "Given the tradition and fashion of food sharing among co-workers, family members, and friends, our findings are notably consistent with the idea that eating together has importance beyond nutritional factors. By applying a functional view of jealousy, our studies yield the inference that people think meals can be more than just meals."
