How "Probiotic" Microbes Control Your Mind

Over the past several years, there has been a barrage of studies about how the vast population of microbes that live in the gut can influence our mind and mood, evidenced by all the products in the grocery store with "probiotic" now slapped on their labels and the wave of interest in "good" bacteria. Researchers out of McMaster University in Canada, in a study in the Proceedings of the National Academy of Sciences, have shown not only that introducing new kinds of bacteria could actually reduce anxiety, but also how the bacteria could be creating that effect.

Paul Forsythe, an assistant professor in the Division of Respirology at McMaster, was one of the study's co-authors. He and his team fed mice a bacteria called Lactobacillus rhamnosus, and then monitored their behavior to gauge their anxiety level. Lactobacillus is a common bacterium. Strains of Lactobacillus are used in the making of food such as yogurt, cheese and breads. Other strains are found naturally in the human gut. However, the strain used in this experiment, researchers said, is different from any of those.

God created those microbes for a reason! We are not to mess with genetics...
