There’s something unique about eating together that’s good for us

Commensality, or the act of sharing meals with others, holds a unique power for our wellbeing. This ancient practice, deeply rooted in human culture, can lower the risk of depression and dementia, increase our enjoyment of food, and even contribute to a longer life. According to Jan-Emmanuel De Neve, a professor of economics and behavioral science at the University of Oxford, "The sharing of meals is an essential mechanism for bonding and building trust and connecting with others."

Studies have shown that the number of people sitting around the table at mealtimes is a clear predictor of someone's risk of depression. A study of 9,361 women aged 60 and over found that regular communal meals were associated with a lower depression risk, even after accounting for factors like health, wealth, and living alone. Similar patterns have been observed in older adults aged 65-74 who live with their families but eat alone, who have five times the odds of developing depressive symptoms compared to those who eat with others.

The World Happiness Report, which surveyed over 150,000 individuals globally, found that regular meal sharing with others is strongly linked to higher emotional wellbeing scores. This effect was as predictive of life satisfaction as employment status and relative income. Researchers believe that eating together may trigger the release of endorphins, those feel-good chemicals that contribute to our natural highs. This bonding over food could enhance our sense of connection with others.

In addition to its mental health benefits, eating together may also protect our brains as we age. Japanese researchers found that people who regularly eat alone show reduced brain volume in regions associated with cognitive function, potentially predisposing them to dementia. While diet may play a role, the reduced social connection appears to contribute to these brain health issues.

The shared enjoyment and enhanced social support of meals could help soothe stress and provide mental stimulation, both of which are crucial for maintaining cognitive function in old age.

Cultural differences in eating practices highlight the importance of preserving these traditions. While the Japanese share fewer meals together compared to the average in the UK and US, Italy's rich food culture, recognized by UNESCO as an Intangible Cultural Heritage, emphasizes the role of meals in connecting with family and community. As we strive to maintain our mental and physical health, the simple act of eating together may offer a powerful solution.
