Social connection may help regulate blood sugar levels

A study published in Science Advances suggests that eating in the company of a loved one may influence how the body manages glucose. Researchers from the Hebrew University of Jerusalem and Sheba Medical Center observed that when participants consumed a standardized carbohydrate meal, such as white wheat bread, in the presence of a partner, their blood sugar spikes were more contained and returned to baseline levels more quickly compared to when they ate alone.

The researchers describe this phenomenon as “social physiology,” suggesting that human connection may help the body manage certain biological functions with less effort. The study noted that these effects were not solely due to reduced stress levels, indicating that social closeness might influence the body through multiple biological pathways.

Beyond glucose regulation, the research indicated that social presence may also assist in better body temperature regulation during cold exposure and is linked to reduced physical stress responses in both adults and infants. The findings suggest that the social context of a meal can have measurable physiological impacts on metabolic health.
