Most people’s refrigerators currently contain a bowl of leftover pasta. Not the fancy kind, the kind you overcook on a Wednesday, reheat twice, and yet manage to find solace at eleven o’clock at night. It’s a minor, somewhat embarrassing detail. However, an increasing amount of psychological research suggests that it may also reveal something authentic about your identity.
Grandmothers have been arguing for decades that food preferences reveal personality, but the science supporting this claim has become much more precise. Researcher Charles Spence’s 2022 review of dozens of studies on taste and personality revealed patterns that are more difficult to ignore than you might think. The results don’t fit neatly into the category of popular psychology. They are more intriguing and unfamiliar than that.
Consider the discovery of bitter food. People who actively enjoy bitter flavors, such as black coffee, dark chocolate, or tonic water, scored measurably higher on traits linked to psychopathy, aggression, and what researchers drily call “everyday sadism,” according to a study of 953 Americans. It’s worth pausing to consider that final statement, which refers to a propensity to take pleasure in minor instances of other people’s discomfort. The connection might just be coincidental. A person’s relationship to discomfort, both their own and others’, may also be revealed by an acquired taste for something that is biologically intended to indicate danger.
It’s almost too tidy on the other side. Individuals who have a preference for sweet foods typically have higher agreeableness scores and appear in studies as being friendlier, more helpful, and more socially involved. There is a reciprocal aspect to it; eating sweet foods not only correlates with more cooperative behavior in studies, but it actually causes it. Researchers are unsure if this is due to the sugar or something more profound about the craving itself. Language may provide an indication: sweetness has been appropriated as a metaphor for kindness in almost every culture. “Honey,” “sweetheart,” “sugar.” It appears that the association is practically hardwired.
Cravings for spicy food follow a different pattern. Heat-seeking is associated with sensation-seeking in general, a personality trait characterized by a desire for novelty, risk, and intensity, according to research. Men who had higher salivary testosterone levels used a lot more hot sauce, according to a lab study. Numerous replications of that discovery have been made. Observing someone methodically drown their food in chili oil makes it difficult to ignore the fact that they are most likely the one who makes last-minute travel arrangements and agrees to things that most people would be hesitant to do.
In particular, comfort food—such as mac and cheese, soup, or a dish that tastes like a person’s childhood—tends to serve as both food and memory. According to research that was published in the New York Times, a lot of people’s enjoyment of their favorite foods stems not from the food itself but rather from what it reminds them of—a person, a location, or a period of time when things were easier. In a way, people who instinctively reach for comfort food during stressful situations may be seeking continuity. That has a certain warmth to it, as well as perhaps a conservatism that leans toward nostalgia.
According to research, picky eaters are more likely to experience anxiety. In a study of 318 college students, it was discovered that higher levels of anxiety were associated with more limited dietary preferences, such as a general apprehension about the unknown that naturally extends to what’s on the plate. It keeps track. At a restaurant that serves eight different cuisines, the person who orders plain pasta is frequently the same person who makes sure the door is locked.
Obviously, none of this is fate. In their darkest moments, people are more than what they desire. However, there’s something subtly revealing about the foods we come back to—not the ones we order to impress, but the ones we prepare on our own, in dim lighting, with no one around.
