Even though everybody agrees that gratitude is a social good, it may have a dark side. Gratitude can drive you to eat more sweets, according to new research by Ann Schlosser, professor of marketing at the University of Washington.
And the more we feel connected to others, the more tempted we are to indulge in sweet things when we’re in a state of appreciation.
“Gratitude has sweet side effects,” Schlosser said. “This study finds evidence that feeling grateful for the helpful—or metaphorically ‘sweet’—actions of others increases preference for and consumption of sweets.”
Flavors as Metaphor
Around the world, people use flavor classifications as easy metaphors for emotions. While salty, sour and bitter often evoke more negative connotations, sweet is almost universally associated with benefiting from the positive actions of another. Empathy. Generosity. Kindness.
But beyond the metaphorical connection, is there an actual connection between kindness and sweetness?
To answer that, Schlosser designed a series of studies triggering feelings of gratitude and other emotions in participants, then measured their tendencies to select and consume sweet or savory indulgences, or nothing at all. Through different variations on this simple design, she found that gratitude elevates one’s preference for sweets.
t does not, however, increase consumption of other kinds of foods. In fact, gratitude actually decreased preference for sour, salty or bitter foods.
“Because gratitude involves acknowledging benefits received from the kind—or metaphorically sweet—actions of another, individuals may infer that they must be deserving of sweetness,” Schlosser said. “As a result, they prefer foods with a congruent sweet taste.”
Pride vs. Gratitude
The study also demonstrates that the positive feeling of pride does not yield the same yearning for sweets as gratitude does because it does not carry the same “sweet” associations.
Another finding of the study is that the effect of gratitude on sweet preferences is strongest for those who feel connected to others. When feeling psychologically separate, Schlosser said, people value independence and tend to view others individually.
When feeling psychologically connected, people see more similarities between themselves and others and view people more interdependently.
“Psychologically-connected individuals are typically more accepting of help and more likely to see themselves as playing a role in the kind act,” Schlosser said. “When they feel gratitude, they feel like they deserve this kind act, this sweetness. Psychologically-separate individuals don’t make as strong a gratitude connection.”
Sugar is considered addictive, and its overconsumption contributes to obesity, high blood pressure, high cholesterol and a litany of other diseases and disorders.
