Kimchi might be the key to calming social anxiety.

A study conducted by researchers from the College of William and Mary suggests that fermented foods like sauerkraut and kimchi play a role in lessening social anxiety.

The researchers conducted a survey about the eating habits, exercise schedule and anxiety levels of over 700 university students enrolled in Introduction to Psychology classes at the College of William and Mary. The survey questions also focused on the student's intake of fermented food.

The results suggested that students who consumed more fermented food felt less anxious in a social setting. This was observed more clearly among students who placed high on "neuroticism" levels. It could be concluded that fermented foods like kimchi, sauerkraut and yogurt can be helpful for those with anxiety concerns. The researchers believe this may be due to the fact that fermented foods are high in probiotics which helps keep the gut healthy and defends it against harmful bacteria.

According to one of the study's authors, Dr. Matthew Hilimire, it is possible "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."

There have been studies linking probiotics to various health benefits to a person's immune and neurological system.

While the study did not explain how probiotics helped lower social anxiety, it mentioned that earlier studies have already connected the link between the two.

Dr. Hilimire tried to explain it further and mentioned that "probiotics reduce the permeability of the gut, so harmful substances don't leak out." It also reduces the inflammation of the gut. And since feelings of anxiety are more often than not accompanied by a stomach ache or other gastrointestinal symptoms, it makes sense that reducing this inflammation will also help relieve anxiety.

The William and Mary research team will also be looking into the mind-gut connection.

The study can be helpful in the treatment of anxiety and other disorders as the findings suggest that traditional therapies like medications, psychotherapy or both can be augmented with fermented foods, a change in a person's diet and regular exercise.
