Grab a yogurt.
A new study out of the University of Maryland has found reason to believe there's a connection between social anxiety and fermented foods containing probiotics, like sauerkraut, yogurt, and kimchi.
The researchers found that young adults who eat more fermented foods had reduced social anxiety, especially those adults who tended toward neuroticism.
"It is likely that the probiotics in the fermented foods are favorably changing the environment in the gut, and changes in the gut in turn influence social anxiety," said William & Mary psychology professor Matthew Hilimire. "I think that it is absolutely fascinating that the microorganisms in your gut can influence your mind."
Presumably, the effect was so strong that it overcame even the added social anxiety of sauerkraut breath.
