But a new study has found yogurt might also treat depression.
Creamy breakfast snack contains lactobacillus, a probiotic bacteria inyogurt cultures live.
Experiments in mice showed only play with this 'good bacteria' werestrong enough to relieve blood pressure, stress, and depression.
They found that the amount of Lactobacillus in the gut affects the level of a metabolite in the blood called kynurenine, what has been shown to drive depression.
When was Lactobacillus diminished in the intestine, levels of kynurenine - and symptoms of depression.
The researchers of the Faculty of Medicine of the University of Virginia claim that the findings show that our growing understanding of theintestinal Microbiome could allow us to naturally treat mental healthwith toxic drugs.
'Great hope for this type of research is that you don't have to botherwith complex medications and side effects when we can only play with the Microbiome,', explained lead researcher Dr. Alban Gaultier.
'It would be magic to change your diet, to change the bacteria that you take, and set your health - and your mood'.
Depression is one of the most common mental health in the United States.
Up to 7 percent of the population experience a major depressive episode, Dr Gaultier took note.
'It is a big problem and treatments are not very good, because they come with huge side effects,' he said.
The role of the intestinal Microbiome - bacteria that live within us - has been of great interest to researchers studying depression and other mental and physical health conditions.
Dr. Gaultier, the Neurosciences Department of the grape and its center of Immunology of brain and glial cells, set out to see if I could finda concrete link between depression and intestinal health.
' When ' you're stressed, increase the likelihood of depression andit's known for a long, long time, said. ' The question you wanted to ask is, the Microbiome participates in depression?'
The answer seems to be Yes.
In the composition of the intestinal Microbiome before and after mice were subjected to stress, Gaultier team found that the main changewas the loss of Lactobacilli.
With the loss of Lactobacilli came the emergence of symptoms of depression. Feed mice Lactobacillus with your food returned to almostnormal.
'A single strain of Lactobacillus,' Dr Gaultier said, 'is able to influencemood'.
He and his team then went on to determine the mechanism by whichdepression affects Lactobacillus.
'This is the most consistent change we've seen through different experiments and different configurations which we call Microbiome profiles,', explained researcher Dr. Ioana Marín, a graduate student.
' This is a constant change. «We see levels of Lactobacillus is directlycorrelated with the behavior of these mice.»
Dr. Gaultier was careful to call symptoms in mice as 'depressive - likebehavior' or 'behavior of despair', as mice have a way of communicating that he feels depressed.
But those symptoms are widely accepted as the best available modelto look at depression in non-human beings.
Based on the new findings, Dr Gaultier plans to begin to study the effect in people as soon as possible.
Proposes to examine the effects of Lactobacillus on depression in patients with multiple sclerosis, a group in which the disorder is common.
Promisingly, the same biological substances and Lactobacillus mechanisms used to also affect mood in mice observed in humans, which suggests that the effect can be the same.
The researchers warned that that yogurt may not yet be considered as a single treatment.
While there is no harm in people with depression eating yogurt, individuals undergoing treatment for depression should not stop taking their medication without consulting their doctors.
