Bacteria found in the human intestine capable of improving muscle strength

grg0: This is why I tell my gym bros that they should quit all that Celsius garbage and stick to the basics. You should measure your gut health by the quality of your feces (consistency, texture, colour, shape), and then your muscles and rest of your body will thank you. This research is evidence of that. The science is still catching up.

acessoproibido: What do you mean by celcius garbage?Fun fact: in Germany most toilets have a built in 'inspection plate' so you can look at your shit before you flush it. In other places I often found it hard to judge the quality because you can't even see it well or it gets flushed instantly

grg0: I meant Celsius, a popular energy drink in the US, but more generally that and the processed foods people take in for some supposed performance gains.

rendall: ...in mice. :/

jb1991: The reflex “in mice” meme has been annoying for quite some time.

toomuchtodo: Roseburia inulinivorans probiotic when? Probably add it to the premade protein shakes and mix.https://en.wikipedia.org/wiki/Roseburia_inulinivorans

Aboutplants: Maybe we need to flip it and start testing new mouse drugs on Humans?

RobRivera: We need deeper research into mouse bites as medicine.

RobRivera: GAINS

stefs: Celsius?

grg0: Corrected, thank you.

stefs: As always. But it's a first step.

rramadass: Perhaps there is also a direct correlation between this microbiome and longevity in the so-called "blue zones" of the world like Okinawa, Sardinia etc.We are what we eat.

wpm: More mouse bites!

shevy-java: So Homer Simpson was right in the end.Beer is basically fermented sugar (well, glucose converted to ethanol by yeast, for the most part; though its maltose first, yeast, bacteria etc... prefer glucose and maltose is a disaccharide of glucose: Maltose).

FurstFly: My gym bros gonna be so shocked lol

ben8bit: Eat some apples and add 10lb to your bench. Nice!

patmorgan23: IIRC there are several of the "Blue Zones" where just bad government records. (People who had incorrect birth dates, or had already died and the government just didn't know about it)

wellthisisgreat: The mouse lobby rears its [tiny] head again

culi: It works by converting fibers into butyrate. You should maintain a high fiber diet to promote Roseburia in your gut

adrian_b: It is known that the bacteria that produce high amount of butyrate are beneficial, e.g. by decreasing the risk of colon cancer, but this does not seem sufficient to explain the increase in muscle strength that seems to be caused by this species alone.The study has first found in humans a correlation between muscle strength and the presence of this bacterium. Then they have attempted to determine whether this correlation is due to a causal relationship by killing the gut bacteria in mice, then feeding them with this kind of human gut bacteria. The result was an increased muscle strength, which seems to confirm causality.How the bacteria increase muscle strength remains unknown. I think that a possible explanation may be that this bacterium produces some substance that mimics a human hormone, e.g. a steroid, in which case it would be a kind of natural doping.

sandworm101: Natural or otherwise, one must wonder if there are similar downsides.

adrian_b: True.

b112: It's literally in the bowl you were just sitting in. I'm not sure where the inspection plate goes. Is this an AI saying this? Is the rest of the thread AIs? Is this all made up. What's happening!?I thought learning about bidets was a new experience, now inspection plates?!I thought I understood this part of my life.scared and confused

ramoz: Did quick research on how to support the bacteria growth> Dietary modifications that emphasize high-fiber and prebiotic foods and dietary supplements may support the healthy growth of Roseburia [1]> As stated above, a Mediterranean diet is associated with increased Roseburia growth. This diet emphasizes primarily plant-based foods: whole fruits and vegetables, whole grains, legumes, nuts and seeds, olive oil, and fatty fish. The high fiber and resistant starch content of these foods may fuel Roseburia and the other beneficial flora of the human microbiome [1]> Polyphenols are plant compounds abundant in fruits, vegetables, tea, and coffee. Emerging research indicates that polyphenols can enhance Roseburia abundance indirectly by inhibiting harmful bacteria and fostering beneficial ones.

OfirMarom: Thanks for the dietary info! Helps make it concrete.

joshuahaglund: No beer has nothing to do with Roseburia genus bacteria

unsupp0rted: I always wondered if the "inspection plate" was really for inspection or some side-effect of plumbing or something

soopypoos: it also helps avoid Neptune's kiss

DiscourseFan: I've always eaten a ton of fiber, to the point where if I stop I get constipated, and I've always put on muscle fairly easily.

b65e8bee43c2ed0: I assume they existed to prevent backsplash.

mikrl: Pretty sure Duff was a heavily filtered macro beer.Not saying engineered beer is necessarily bad- Sapporo and Asahi never disappoint- but I imagine you would want to stick to unfiltered and unpasteurized to retain some of the more… alive compounds.

soopypoos: my hobby is shitting myself

p1anecrazy: One explanation I heard is “helps save water when flushing”

moffkalast: You know it would be funny if at least once the finding would be "you should eat more hamburgers" or something.

kadoban: It's just different shapes of toilets. There's a part without water directly under you, and then when you flush it's flooded.

adrian_b: It is not that simple.They have found first a correlation between the presence of this species of bacteria and muscle strength in humans.Then they have made an attempt to determine whether this correlation reflects a causal relationship.So they have fed mice previously treated with antibiotics, to remove their own gut bacteria, with this kind of bacteria extracted from humans.They have indeed seen an increase in muscular strength at the mice that have received the human bacteria, which seems to confirm causality between the presence of this bacterium and muscle strength.While they have also determined the biochemical changes in muscles that have caused increased strength, the mechanism of how the bacteria have influenced that remains a mystery. Perhaps this bacterium produces some substance that mimics a human hormone, e.g. a steroid.Paywalled research article: https://gut.bmj.com/content/early/2026/03/03/gutjnl-2025-336...

rendall: So, literally, "Bacteria found in the human intestine capable of improving muscle strength in mice" then.

SV_BubbleTime: Jose DeSanquin Demarco of Bolivia is now the world’s oldest man at 117, he attributes his health to 10 hours daily in the sun and fields farming quinoa.

g-b-r: Will people really go after Tom Brady's stuff now? xD

emanuele-em: Every few months there's a new study showing gut bacteria control yet another thing we thought was "us." Mood, cognition, immune response, and now muscle strength. Starting to wonder what's even left.

dd8601fn: And yet, still no serious fixes for any of it that aren’t just jabronis pitching overpriced supplements.

youalmosthadit: No grain no gain

sharpshadow: Active cultures are available[0] and there is certainly a way to make them available to the gut isn’t there?0. https://webshop.dsmz.de/en/bacteria/Roseburia-inulinivorans....
