Probiotic Bacteria Induce a ‘Glow of Health’

Probiotic Bacteria Induce a ‘Glow of Health’

Radiant skin and hair are universally recognized as indications of good health. However, this ‘glow of health’ display remains poorly understood. We found that feeding of probiotic bacteria to aged mice induced integumentary changes mimicking peak health and reproductive fitness characteristic of much younger animals. Eating probiotic yogurt triggered epithelial follicular anagen-phase shift with sebocytogenesis resulting in thick lustrous fur due to a bacteria-triggered interleukin-10-dependent mechanism. Aged male animals eating probiotics exhibited increased subcuticular folliculogenesis, when compared with matched controls, yielding luxuriant fur only in probiotic-fed subjects. Female animals displayed probiotic-induced hyperacidity coinciding with shinier hair, a feature that also aligns with fertility in human females. Together these data provide insights into mammalian evolution and novel strategies for integumentary health.

Estrogen and serotonin are increased by poor gut health and endotoxin absorption, suppressing testosterone. My guess is this is about gut health and not probiotics per se. You probably get the same effects without probiotics from a diet that keeps the gut relatively cleaned out of biofilms. In practice this means avoiding complex starches and excess protein that make it through to the lower intestine to feed bacteria. Some unfermentable soluble fiber to clean things out helps. Sugars and simple starches are absorbed in the sterile upper intestine and don’t feed the problem bacteria.

Resistant starches are prebiotics for probiotics.

You want bacteria in the lower intestine just the right kind. You get the right kind from resistant starch. Potato starch is good.

Any idea why most probiotic supplements (at least that I have come across) do NOT contain Lactobacillus reuteri (the main bacterium used in the study)? Is supplementation generally unnecessary because L. reuteri is so common? Just wondering!

I was reading about probiotics here.

People were getting very good results from them but they had to eat Kraut to do so. Ack!! So looking around I found Kefir water has many of the bacteria known to help immune function. I hate kraut. I hate sour foods. This might be an easier way to get what you need.

“…L. brevis is one of the major Lactobacillus species found in tibicos grains (aka water kefir grains)…”

After reading your post I looked around and saw that water kefir can also have Lactobacillus reuteri in it.

Stuffs cheap. I bought some but it got thrown away while I was waiting for bottles. Going to try for some more. I wonder if you couldn’t just take some of the better probiotic capsules and make water kefir with those. The only problem being where the yeast would come from.
