Thanks a lot A new study suggest that our gastro intestinal system is connected with our brains, and that connection is able to affect our mood. Inside the human body about 300 to 500 different species of good bacteria called probiotics can live. These microorganisms play an important role in the digestion and the neuronal activity, a new report suggested that the presence or lack of probiotics affect the mood. Canadian researchers evaluated the effect of probiotics in people with irritable bowel syndrome. The half of the patients were given probiotics daily and the other half received a placebo. At the beginning of the research, the scientists evaluated the levels of depression of the people. They showed happy and sad images to the patients, at the same time a machine was recording their brain response. Six weeks after. The 60% of the patients that received probiotics showed a reduction of their depression score. The early research suggest that exist a connection between the gastro intestinal system and the brain. In addition, the probiotics can help to cut down depression helping at gastro intestinal system working right.
