Israeli Study Shows Blood Glucose Levels Are Lower When You Eat With Someone You Love
If you watch old TV shows from the 50s and 60s, you usually see families eating dinner together. Breaking bread together and the conversations that go with it can do more than feed your body and soul, it can also be good for your health. But what does eating meals with family and friends have to do with how your body processes the nutrients it takes in?
Actually, quite a bit. According to a 2026 study led by researchers from the Hebrew University of Jerusalem and Sheba Medical Center in Tel Hashamer, social interactions can positively impact blood glucose levels, temperature regulation, as well as stress levels.
The Times of Israel reported that the peer-reviewed research, which involved 339 participants, found that people who ate with other people had lower blood spikes that returned to normal faster than people who ate alone.
In the glucose portion, participants were given a standardized serving of 50 grams (1.76 ounces) of carbohydrates. The two other sections were a temperature test and a stress experiment.
The study ran for three years and was led by Professor Shir Atzil of Hebrew University’s Department of Psychology, first author Monia Masalha and a team of researchers. Here’s what they found.
Social Physiology
Atzil has been studying the biological and neural basis of social bonding for a decade. This principle, called social physiology, explains that the human body regulates itself more effectively in the presence of people they care about, reported The Jerusalem Post.
“Our findings show that human physiology is inherently social. Being close to someone you love lowers the physical energy your body spends on regulating itself. This gives us a direct metabolic benefit to being together and reveals a core evolutionary reason why humans form bonds in the first place: our bodies run better together,” Atzil told The Jerusalem Post.
The concept was originally greeted with skepticism. But it was funded by a European Research Council Starting Grant to study human connections and how they affect the body.
The researchers explained that social closeness does not replace nutrition, exercise, and medical care but the study proves that it is a factor that has been overlooked before, how other people affect your health is opening new areas to explore.
Understanding the Results
The study is a biological framework to understand the links between people’s inward and outward lives, according to Science Alert. It shows that eating dinner alone can do more harm than just being lonely. The lack of connections can change the way that your body processes what you eat.
While prior work has focused on the negative outcomes of social isolation, including heart health, cancer, and metabolic disorders. The recent study presents a qualitative scientifically proven report about the benefits of social proximity in the metabolism of glucose.
Medicine has shown that people who have more ties to society are usually healthier, happier, and live longer. Surrounding yourself with loved ones at family meals, holidays, and social events is good for your body and soul.
