If you are expecting eating yogurt, which is rich in probiotics, to reduce your anxiety, you might be wrong. While consuming probiotics may be good for your digestive system, it may not be effective in decreasing your anxiety levels, say researchers.
The study found evidence that probiotics found in yogurt and supplements can reduce anxiety in rodents, but not in humans.
"Probiotics did not significantly reduce symptoms of anxiety in humans," said lead author Daniel J. Reis from University of Kansas.
However, the researchers said their findings should not close the door on probiotics as the micro-organisms in yogurts and other products that take up residence in our guts may be a potentially useful therapy for anxiety and other cognitive issues in the future.
"We're in the early days of this research into probiotics. We're not saying they do nothing, but we have a lot to figure out before we know if they can be used therapeutically," Reis said.
