Eating alone? Your health is at risk

New research shows that eating alone is linked to an increased risk of depression, lower life satisfaction, and even reduced brain volume. Analysis of the 2025 World Happiness Report and other studies has found a consistent connection between shared meals and psychological well-being. Israeli experts confirm that the social aspect of eating is critical for mental health.

New research shows that eating alone is linked to an increased risk of depression, lower life satisfaction, and even reduced brain volume. Analysis of the 2025 World Happiness Report, prepared by scientists from Oxford, Gallup, Harvard, and UCL, covered responses from over 150,000 people in 142 countries. It found that the more often people ate together, the higher they rated their lives and the less they experienced negative emotions. This connection was stronger among young people aged 16-24 and among women. Another study, covering about 235,000 Americans from 2003 to 2023, showed that in 2023, 26% of participants ate all of the previous day alone—50% more than in 2003. Among people aged 25-34, this figure increased by over 180%. Americans who ate alone rated their lives half a point lower on average. A Japanese study of 727 70-year-olds found that those who ate alone had a smaller overall brain volume and smaller volumes in several areas related to cognitive function. Israeli experts—clinical psychologist Mirey Danon and neurologist Dr. Merav Hen—confirm that the social aspect of eating is critical for mental health, and that regularly missing shared meals can lead to a vicious cycle of loneliness and depression.
