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
I thought learning about bidets was a new experience, now inspection plates?!
I thought I understood this part of my life.

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).
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.
We are what we eat.

putting together a theory on how bacteria organized multicellular life to exploit our macro-movements and proliferate between damp spots
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.
Maybe, but it's really hard to control for other variables here. They don't know what's causing this bacteria to diminish over time in older adults in the first place.
It could totally just be dietary habits getting worse over time as people let themselves go. Regardless of age, most people already don't eat enough protein and when they do they might not be getting "complete" proteins either (missing amino acids is common with plant-based foods).
> 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. [2]

I wish scientists would be more open about how little they understand digestion and nutrition, particularly on an individual level. Advice gets presented as an if-then, when it's not.

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.
