It is a distinctly human trait: our fondness for gathering around a table to share a hearty meal. Dining out with friends, hosting dinner parties, or indulging during festive holidays are so ingrained in our routines that we hardly notice them—except when society suddenly worries we’re not doing it enough.
Concerns about the decline of the family dinner, for example, frequently dominate headlines. Evidence suggests such anxieties are far from new, stretching back at least a century. All of this hints at something important: communal eating is not just widespread, but profoundly meaningful. The question is—why?
Sharing food itself predates the emergence of Homo sapiens. Chimpanzees and bonobos, our closest primate relatives, have long been observed offering food within their social groups. Yet, as Nicklas Neuman, a sociologist at Uppsala University in Sweden, notes, giving food is not the same as sitting down to eat together. “You can distribute food without actually sharing a meal,” he says. Humans appear to have layered this basic act with rich social complexity.
The earliest shared meals likely took place around a fire. While the origins of cooking remain uncertain—estimates range as far back as 1.8 million years—preparing food requires cooperation: gathering ingredients, building a fire, and cooking itself. A campfire would have created both light and warmth, drawing people together and keeping them awake longer, suggests Robin Dunbar, a biological anthropologist at the University of Oxford. Those extra hours may have provided crucial opportunities for social bonding.
Whatever its beginnings, communal eating today is strongly linked to wellbeing. In a 2017 study, Dunbar found that people in the UK who ate with others more frequently reported greater life satisfaction and had more reliable social networks. His statistical analysis indicated that shared meals actively foster these bonds, rather than merely reflecting them.
“Eating activates the brain’s endorphin system—the chemical foundation of bonded relationships in primates and humans,” Dunbar explains. “When we eat as a group, the effect intensifies, much like when people jog together, because synchronised activity roughly doubles endorphin release.”
Sharing a meal, however, is not always straightforward—or universally positive.
Eating the same food at the same time can increase trust, according to journalists Cynthia Graeber and Nicola Twilley, who explored this topic on their Gastropod podcast. Citing research by Ayelet Fishbach of the University of Chicago Booth School of Business, they note that participants in an investment simulation were more willing to allocate money to someone with whom they had previously eaten identical sweets. Similarly, pairs who shared the same snacks reached agreements faster during negotiations. Fishbach suggests this may be an evolutionary remnant from a time when similar tastes in food signalled shared values.
Yet communal eating can also reinforce hierarchy and power. Feasts—lavish meals where abundance is meant to be displayed—have historically served as a stage for dominance and submission. Consider harvest celebrations where landowners feed their labourers, or office parties where employees meticulously judge their employer’s generosity. Even everyday family dinners, celebrated as they are, can be charged with tension. “People will say they enjoy shared meals with loved ones, but it can also be unpleasant,” Neuman says. “It’s a setting where control and dominance emerge.” Meals that involve constant criticism—of choices, behaviour, or weight—do little to support anyone’s wellbeing.
