Researchers at the University of Virginia School of Medicine found that lactobacilli, a bacteria found in fermented foods and yogurt, help the body cope with stress and prevent depression. results published in the field of Brain Behavior and Immunity (BBI).
The human gut microbiome is a unique community of microorganisms (bacteria and fungi). Scientists explained that their number and interaction with each other have an impact on the immune system and mental health. Gut dysbiosis, caused by malnutrition or other causes, is known to contribute to the development of many diseases, including depression, anxiety disorders and cancer.
The research team focused on lactobacilli, a type of probiotic bacteria that is part of the normal human gut flora and is found in fermented (sauerkraut) and fermented (yogurt) foods. To do this, they conducted an experiment involving laboratory mice. Scientists excluded lactobacilli from the microbiome of rodents in the first group.
Scientists have discovered that lactobacilli from the family Lactobacillacea are responsible for maintaining normal levels of an immune mediator called interferon gamma, which regulates mood and the body’s response to stress. Their presence in the body is associated with a lower risk of developing anxiety and depression.
The researchers hope their discovery will lead to the development of new ways to prevent and treat mental disorders. For example, create special probiotic supplements that optimize the level of beneficial lactobacilli for patients suffering from (or at risk of) depression.
