Coincidently read this article and
received a note from a friend who said that some probiotics and supplements she was taking have incredibly elevated her mood. I thought it worthwhile to post a snippet from and link to the article.
Gut Bacteria May Exacerbate Depression
By Tori Rodriguez
“The digestive tract and the brain are crucially linked, according to mounting evidence showing that diet and gut bacteria are able to influence our behavior, thoughts and mood. Now researchers have found evidence of bacterial translocation, or “leaky gut,” among people with depression”.
“Normally the digestive system is surrounded by an impermeable wall of cells. Certain behaviors and medical conditions can compromise this wall, allowing toxic substances and bacteria to enter the bloodstream. In a study published in the May issue of Acta Psychiatrica Scandinavica, approximately 35 percent of depressed participants showed signs of leaky gut, based on blood tests.”
“Bugs That Influence the Brain
Preliminary research suggests that these common gut microbes can also affect our thoughts and feelings.
1. Helicobacter pylori: Children infected with this ulcer-causing bacterium performed worse on IQ tests, suggesting a possible link between H. pylori infection and cognitive development.
2. Lactobacillus helveticus and Bifidobacterium longum: Healthy human volunteers who consumed a probiotic mix of these bacteria exhibited less anxiety and depression.
3. Probiotic bacteria B. animalis subsp. lactis, Streptococcus thermophilus, L. delbrueckii subsp. bulgaricus, L. lactis
subsp. lactis: Healthy women who consumed yogurt containing these bugs showed less activity in brain regions that process emotions and physical sensations. Researchers do not yet know whether these effects were beneficial; they also have not discovered the mechanism underlying the observed shift in brain activity.
4. Lactobacilli: Healthy students had fewer of these bacteria present in their stool during a high-stress exam time compared with a less stressful period during the semester. The findings suggest a potential link between stress and gut microbes, but the exact relation remains unknown”.
