Hugh, probiotic question

Posted by beckett2 on March 17, 2019, at 23:10:59

Hi Hugh, is lactobacillus rhamnosus the bacteria found to be beneficial for the vagus nerve/mood connection?

There was a discussion of kefir sometime back that I cannot find. I recall you saying something definitive (a little definitively at least).

A friend makes delicious water kefir, but it does not have lactobacillus rhamnosus. I'm back to drinking kefir, and want to avoid all the plastic bottles from the market.... Looking at kefir grains.

I found this:

The afferent neurons of the vagus nerve are the targets by which neuroactive bacteria such as L. rhamnosus and B. longum transmit microbial messages to the brain. The vagus nerve contains 80 and 20 percent of afferent and efferent fibers, respectively. A healthy microbiota produces copious amounts of short-chain fatty acids, such as butyric acid, which directly activate afferent vagal terminals and send messages from the gut to the brain. (3) However, live bacterial species are not the only requirement for bacterial vagal nerve stimulation. As evidenced by B. fragilis, a lipid-free polysaccharide is both necessary and sufficient for activation of vagal afferent neurons. (4) Toll-like receptor 4 (TLR4) are expressed on vagal afferent fibers and can sense bacterial products such as lipopolysaccharides (LPS) to activate both the afferent fibers and the brain. (5)

Thanks! That is helpful. The grains I'm looking at have L. rhamnosus. Fascinating about the polysaccharides.

Are you still making kefir?

You're welcome. I haven't made kefir in quite a while. It's so much easier to buy it. But it isn't that hard to make it, especially with the packets. I never graduated to making it with kefir grains. Good luck.
