New research indicates that dining with a close partner might have an unexpected influence on bodily functions, particularly how the body manages blood sugar levels after eating. While the effects seem to vary among individuals, the study pointed out that sharing a meal with a loved one leads to a smaller increase in glucose levels and a quicker return to normal compared to eating alone.
In the study, participants were served meals with identical types and quantities of carbohydrates, and their blood glucose levels were monitored post-meal. Despite these interesting findings, it’s important to note that not everyone will react similarly.
Shir Atzil, Ph.D., who co-authored the study and teaches at Hebrew University of Jerusalem, shared with Fox News Digital that significant individual differences were observed in how much people benefited—or even regressed—during shared meals. “Some people experience a considerable advantage from dining with their partners,” Atzil noted. “Others see only a minor benefit, and, quite interestingly, a few may actually have better regulation when dining alone.”
This research, published in late September in the journal Science Advances, is rooted in the concept of social physiology, which investigates how being in close proximity to a partner can shape physiological processes in our bodies. Atzil explained that this theory suggests our fundamental physiological functions, or how our bodies maintain balance, could work more efficiently when we are near a close companion.
Nonetheless, Atzil emphasized that further research is necessary to grasp the reasons behind the differing responses among individuals. She intends to keep exploring the social physiology theory and mentions that the social environment is just one of numerous factors influencing blood glucose levels.
Erin Palinski-Wade, a registered dietitian from New York specializing in diabetes, added that the type and quantity of carbohydrates ingested are critically important for blood sugar regulation. Moreover, she highlighted that blood sugar levels can be affected by various elements, such as stress, sleep quality, physical activity, and even environmental factors.
“Stress, how well you slept the night before, your activity level on a given day, and even the room temperature can all influence blood sugar,” she said. Maintaining healthy blood sugar levels post-meal is crucial, as consistently high glucose can lead to serious health complications like heart, kidney, eye, and nerve damage, as noted by the National Institutes of Health. The Centers for Disease Control and Prevention (CDC) recommends that many individuals with diabetes check their glucose levels two hours after meals to help manage or prevent serious health issues.
