Frequent consumption of restaurant meals is associated with an increased risk of premature mortality, suggesting that cooking more at home would be more beneficial for longevity.

The cited study (Journal of the Academy of Nutrition and Dietetics) is an observational analysis based on NHANES data; it shows a statistical correlation but cannot establish a direct cause-and-effect link. As community members point out, this type of study is subject to major confounding factors, such as socioeconomic status, stress levels, overall lifestyle, and access to healthcare, which strongly influence mortality. It is likely that the average nutritional quality of meals prepared outside the home (often higher in trans fats and sodium, as noted by users) plays a role, but the effect is likely amplified by lifestyle habits related to the individuals' living conditions. The community is divided between cautious acceptance of the correlation and skepticism toward simplistic causality, rightly pointing out that nutritional quality varies drastically depending on the type of restaurant and food culture. In short, although the association exists, it is likely a marker of overall lifestyle rather than a unique condemnation of eating at restaurants.
