Eating With a Close Companion Was Linked to Smaller Blood Sugar Spikes

• 

  A study published in Science Advances found that participants’ blood sugar rose less and returned to baseline faster after eating white bread beside a close companion than when eating alone.

• 

  The study involved 108 people who ate a little over 100 grams of white bread in each of two settings, with blood sugar tracked for two hours afterward.

• 

  Researchers also found better body-temperature and nervous-system regulation when participants were near a close social partner.

• 

  The researchers said the study identified a link but did not establish why having a companion was associated with steadier blood sugar.

• 

  A separate 2024 study of 665 people with diabetes found that those with less social support had significantly higher average blood sugar levels than those with more support.
