A major global study suggests that eating with others may be a simple, measurable sign of stronger social connections and improved well-being, while rising rates of dining alone in the US raise fresh concerns about everyday isolation.

A large global study published in the journal scientific report Suggests that something as simple as sharing a meal can play a powerful role in well-being.
The researchers found that the frequency of eating with others, an indicator of social connectedness, was associated with better well-being and had more predictive power than some key socioeconomic indicators such as income and unemployment.
Drawing on last week’s global survey data and We According to daily time-use and health data, studies show that shared meals are linked to higher happiness and lower stress, while eating alone in the United States, an increasingly common trend especially among young adults, is related to worse health outcomes.
Social connections underpin health, happiness, and prosperity, shaping outcomes ranging from mental well-being to longevity.
People who maintain strong social ties report greater life satisfaction, less stress, and lower disease risk, while also demonstrating higher levels of trust, cooperation, and civic engagement.
In contrast, loneliness and isolation are linked to poor health, shorter lifespan, and adverse social outcomes.
Emerging research suggests that shared meals may provide a simple but meaningful path to strengthening these relationships, with studies linking meal sharing with better nutrition, better mood, and fewer depressive symptoms.
However, despite its near-universal nature, the relationship between social eating patterns and well-being is surprisingly underexplored.
Evaluating average life based on number of meals shared in the last week Gallup World Poll, 2022-2023
Global and US food sharing study design
In the current study, researchers combined global and national datasets to examine the relationship between eating and well-being, among others. They analyzed data from the 2022-2023 Gallup World Poll (gwp), covering more than 150,000 respondents from 142 countries and regions.
Participants reported how many days in the past week they shared lunch or dinner with an acquaintance.
To capture trends over time in the United States (We), the team also used the 2003–2023 American Time Use Survey (on us), involving over 239,000 respondents, with its Wellbeing module, which captured the emotional experiences of over 25,000 participants using the Day Reconstruction method.
The researchers applied linear regression models to examine the relationships between food sharing, life ratings, and both favorable and unfavorable emotional states.
They controlled for country fixed effects and county fixed effects as well as demographic and socioeconomic variables including age, gender, education, income, employment status, and household size in the global analyses. We Analyzes.
Additional models examined variation in different household compositions using interaction terms.
In We In the sample, the team compared individuals who ate all meals alone with those who shared at least one meal, estimating differences in well-being using weighted analyzes to ensure population representativeness.
They also explored subgroup variation by marital status, employment, and remote work patterns. A series of robustness checks confirmed the stability of the findings, with most analyzes conducted using ordinary least squares regression.
Food sharing and well-being outcomes
The analysis revealed a significant positive relationship between food sharing and well-being in almost all world regions.
On average, sharing one extra meal per week led to a 0.2-point increase in well-being on a 0-10 scale, an effect equivalent to the well-being cost associated with a 1.5 percentage-point increase in inflation.
Notably, even a shared meal made a difference: individuals who shared a meal at least once recorded a better overall life rating than those who did not share a meal (5.2 vs. 4.9), a difference that is about half the size of the welfare loss associated with unemployment.
These associations remained strong even when controlling for education, income, and employment, with food sharing accounting for much of the variation in well-being as key socioeconomic indicators. This pattern is based on age and gender groups and extends to both favorable and unfavorable emotional situations.
Globally, the frequency of eating with others is highest in Latin America, while levels are lower in South and East Asia.
The strength of this relationship was particularly evident in Australia, New Zealand, and North America, although the regional pattern was neither completely linear nor uniform.
Dining alone trends in the United States
In WeThe two-decade trends showed a significant increase in dining alone, with 26% of adults reporting that they ate every meal alone in 2023, an increase of more than 50% since 2003. Individuals who dined primarily alone reported less happiness and higher levels of stress, pain, and sadness, as well as life ratings about 0.5 points lower than those who dined with others.
Although the absolute rates of eating alone were higher among older adults, younger adults showed a somewhat steeper increase over time.
The findings underscore the strong, consistent relationship between social eating and well-being, suggesting that even modest increases in shared meals could yield meaningful benefits at both the individual and population levels.
Shared meals as a well-being strategy
Overall, these findings present shared meals as a simple, scalable lever to support well-being at both the individual and societal levels. Because food sharing is a universal and easily measurable behavior, it provides researchers and policy makers with a practical proxy for social connectedness and a potential target for intervention.
There has been a sharp increase in the trend of eating alone, especially among young adults WeHighlights the urgent need for in-depth investigation of its underlying drivers and long-term consequences.
Future research should move beyond the association to examine causal pathways, including the role of interaction quality, work patterns, and cultural context. If confirmed, promoting shared meals could represent a low-cost, actionable strategy for strengthening social relationships and improving population well-being.
