Ask ten people what comfort food means to them and you will likely get ten different answers. For one person it might be a bowl of chicken soup made the way a grandmother used to make it. For another it could be a slice of cold pizza eaten straight from the box at midnight. There is no single recipe for comfort, and that is precisely what makes the subject so interesting.
Researchers have spent years trying to pin down why certain dishes soothe us while others simply fill a stomach. The answers touch on memory, culture, biology, and even the political mood of a country. What follows is a closer look at the many layers behind a phrase we all use but rarely stop to examine.
The emotional wiring behind comfort food
Scientists studying food and emotion have found that comfort is not really about taste at all, at least not in the way most people assume. A recent set of experiments led by social psychologist Chelsea Reid at the College of Charleston asked participants to think about or actually taste a range of foods, then rate how much nostalgia and comfort each one produced. When they asked participants to rate foods on their ability to evoke feelings of nostalgia and comfort, they found that the more nostalgia a food inspired, the more likely it was to make the participant feel comforted, with participants recalling times when they felt connected to others.
What stood out in the findings was that the food itself was almost a side character. The comfort food served as a reminder of missing friends and caregivers, according to Reid. Interestingly, in three out of four of Reid’s experiments, participants didn’t actually eat anything at all, which suggests the mental association can matter as much as the physical eating.
Childhood dishes leave a lasting imprint
A great deal of what we consider comforting traces back to the plates we grew up with. A 2025 sociological study out of the University of Pittsburgh took a deep dive into this idea through long interviews with a diverse group of adults. Nearly every one of the 27 demographically diverse participants, each interviewed for about an hour across several occasions, described an emotional attachment to particular dishes they ate as children, though the specific dishes varied by culture.
Those early meals were not just about nutrition. The experiences steeped the foods in memories of good times, of feeling safe and cared for, and as adults, participants said they turned to those foods during bouts of loneliness. It is a reminder that comfort food is often less about the dish and more about the years we spent eating it around people who loved us.
Culture decides what counts as comforting
What soothes someone in Ohio may not register at all with someone raised in Seoul or Bogotá, and that gap is not a small detail. It is the whole point. Comfort food choices are profoundly influenced by cultural background and personal experiences, and dishes considered comforting in one culture may be unfamiliar in another, reflecting the diversity of comfort food across global cuisines.
The examples make this concrete. A comforting meal in the American South might include a hearty serving of grits and biscuits, while in Japan, a soothing bowl of miso soup might serve the same purpose. One writer covering the topic recently put it in personal terms, noting that had she been raised in Vietnam, she might opt for pho, a soothing beef broth with rice noodles and fresh herbs, or in Colombia, ajiaco, a restorative soup of chicken, potato and corn. The dish changes, but the underlying need for warmth and familiarity does not.
Age and gender shape our cravings too
Comfort food preferences do not just split along cultural lines. They also shift depending on who is doing the craving. Older research on comfort food patterns, still frequently cited by food scientists, found that women gravitate towards sweet and snack type foods to provide them comfort, whereas men crave meal-related foods when feeling down.
Age plays a role as well. Studies summarized in food behavior literature note that younger people are seen to comfort eat more than older people, though older adults are not immune to the pull of nostalgia. A 2025 study on older adults and prepared meals found that increased nostalgia experienced during meal consumption also increased overall liking, suggesting that the emotional weight of familiar textures and flavors does not fade with age, it just attaches to different memories.
Comfort food as a marker of identity
Beyond the personal, comfort food carries a social function that anthropologists have documented for decades. From a sociological or anthropological perspective, comfort foods provide a sense of cultural identity, tying individuals to the group they grew up in. A pot of gumbo, a plate of pierogi, or a bowl of congee is never just dinner. It is a small, edible flag of belonging.
This identity function helps explain why people often defend their comfort foods so fiercely, even when outsiders find the dish strange or unappealing. Comfort foods can tie closely to a group’s personal identity, which means criticizing someone’s favorite dish can feel, on some level, like criticizing where they come from. That emotional stake is part of why comfort food conversations get surprisingly heated at family dinners.
Stress and uncertainty push us toward familiar plates
Comfort food consumption tends to rise whenever life feels less predictable, and the last several years have offered plenty of evidence. A survey from the International Food Information Council found that sixty percent of Americans say they have been somewhat or very stressed over the past six months, and as a result, fifty one percent admit they’ve been more likely to consume more food and beverages that are less healthy than they usually eat.
This pattern is not new, and it shows up during collective crises as much as personal ones. Research on sales data has shown that immediately after periods of societal uncertainty and national crises, the sales of comfort foods, such as soup, mashed potatoes, and macaroni and cheese, increase. It seems that when the wider world feels shaky, people reach for the plates that once made a smaller, safer world feel manageable.
The biology of why certain foods calm us down
There is also a straightforward chemical piece to this puzzle, and it partly explains why so many comfort foods lean sweet, salty, or rich. Comfort food often has higher levels of sugar, fat, and carbohydrates, and according to the online food marketplace Goldbelly, these substances trigger the release of dopamine, the so called happiness hormone.
There is a physical reason these foods go down easily, too. Research on ultraprocessed foods shows that we consume them faster than unprocessed or minimally processed foods, taking in up to twice as many calories per minute, partly because processing strips away the ingredients’ innate structure, so the product goes down quicker. The brain gets its reward, and the body barely has to work for it, which is a combination that is hard to resist during a rough week.
Not every comfort food is unhealthy
It would be easy to assume comfort food is always synonymous with indulgence, but that assumption does not hold up globally. A recent review of the research made the point directly, noting that to many Americans, comfort food is synonymous with indulgence, but the food’s nutritional value varies by culture.
Broth based soups, rice dishes with vegetables, and simple stews show up as comfort foods in many parts of the world, and they carry a very different nutritional profile than fried chicken or ice cream. Not all comfort foods are unhealthy, as seen in cross cultural samples of comfort foods used in recent research comparisons. This matters because it separates the emotional function of comfort food from any fixed idea about what it has to contain.
Rethinking comfort food without losing the comfort
Given how tightly nostalgia and comfort are linked, some researchers see an opening for healthier eating that does not feel like a punishment. One recent overview suggested that because nostalgia plays a big role in the meals that bring us solace, we might be able to recondition ourselves toward healthier foods that still soothe.
Food scientists studying meal acceptance among older adults reached a similar conclusion from a different angle. Their 2025 study found that liking of meals also increased if a higher experience of comfort was elicited during meal consumption, while perceived comfort decreased if there was insufficient flavor. The takeaway is fairly practical: comfort does not have to be abandoned in the name of health, it just has to be built into the redesign from the start rather than treated as an afterthought.
Final thoughts
Comfort food resists a tidy definition because it was never really about the food to begin with. It is about the kitchen someone grew up in, the culture that shaped their palate, the stress they are carrying this week, and the people they miss without quite realizing it. The dish on the plate is just the messenger.
That is probably why the topic keeps drawing researchers back, year after year. Every new study seems to confirm the same quiet truth, that what we eat for comfort says less about hunger and more about what, or who, we are trying to feel close to again.
