Lets talk some more about our preferred microorganism, Lactobacillus reuteri, and its results on humans:.
L. reuteri, when present in the human intestinal (GI) tract, takes up home in both the colon and upper GI system, unlike most other probiotic types that only colonize the colon. (I therefore think that L. reuteri supplies benefit in avoiding upper GI colonization by unhealthy microorganisms, i.e., SIBO.).
L. reuteri provokes the hypothalamic/pituitary release of the hormonal agent oxytocin (a result mediated through specific T-cells and the vagus nerve).
Oxytocin is connected with sensations of affection, love, connection, desire for human friendship, love for a child, love for an animal, belonging to a group.
Oxytocin is likewise related to causing increased dermal collagen, thicker moister skin, acceleration of healing and hair development, remediation of youthful muscle and strength, decrease of appetite, increased sex drive, deeper sleep, conservation of bone density.
L. reuteri has been recovered from the microbiomes of primitive people such as those from Papua, New Guinea, with every individual bring the species. More recent analyses suggest that many individuals in Western society, however, have actually lost L. reuteri, likely a consequence of direct exposures to such things as emulsifying agents, artificial sweeteners, antibiotics, glyphosate, chlorpyrifos, heavy metals, and so on, i.e., the lots of factors in contemporary life that have actually improved the structure of the human microbiome. (L. reuteri is not alone; there are most likely dozens, perhaps hundreds, of other species that contemporary people have actually lost. Ponder what this could suggest, nevertheless: If most contemporary people have lost L. reuteri and consequently its oxytocin-boosting capability, while we as a society are suffering record-setting levels of social isolation (even prior to the pandemic constraints), suicide, and divorce, could these phenomena be related?
The German microbiologist, Dr. Gerhard Reuter, discovered this microbe in the 1960s, labeling it Lactobacillus fermentum. Subsequent analyses revealed essential distinctions in this species and it was renamed L. reuteri after its originator.
The extensive and early work by Dr. Reuter detailed how he recuperated L. reuteri from the upper GI tract and how it was present in the bulk of digestive specimens he studied. Likewise, L. reuteri has been recuperated from the microbiomes of primitive people such as those from Papua, New Guinea, with every specific bring the species. More current analyses suggest that the majority of people in Western society, however, have lost L. reuteri, likely an effect of exposures to such things as emulsifying representatives, artificial sweeteners, prescription antibiotics, glyphosate, chlorpyrifos, heavy metals, etc., i.e., the lots of consider contemporary life that have actually improved the composition of the human microbiome. (L. reuteri is not alone; there are probably dozens, possibly hundreds, of other types that modern-day people have lost. Bifidobacteria infantis, for circumstances, is another.) It is now rare to discover L. reuteri in a modern-day individuals microbiome.
Techniques to determine oxytocin are, even today, of doubtful reliability, offered the antibodies used to determine it and the current recognition that most oxytocin is bound to other molecules and was for that reason improperly measured in earlier studies. Ponder what this could indicate, however: If most contemporary individuals have lost L. reuteri and therefore its oxytocin-boosting capacity, while we as a society are suffering record-setting levels of social seclusion (even before the pandemic limitations), suicide, and divorce, could these phenomena be related?
Hard to prove. But I will tell you that a growing number of people who consume the L. reuteri yogurt that yields more than 200 billion CFUs per 1/2-cup serving (via our circulation cytometry assays; the most current count yielded 262 billion)– i.e., far more than the millions supplied by the bacterial probiotic source– are reporting increased feelings of empathy for other individuals, closeness to their partners and households, less social anxiety. A variety of individuals inform me that they feel compelled to introduce themselves to complete strangers.
L. reuteri, with bacterial counts boosted by means of our yogurt-making efforts, offers a fantastic example of the emerging world of psychobiotics, i.e., bacterial species/strains that have important effects on the human mind.
