The Claim
In post-weaned rats, urinary microbial metabolites including acetate and trimethylamine are correlated with brain metabolites including formate and adenosylhomocysteine.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In rats after weaning, levels of certain microbial byproducts in urine are statistically linked to levels of specific chemicals in the brain.
See the scientific wording
In post-weaned rats, urinary microbial metabolites such as acetate and trimethylamine are correlated with brain metabolites including formate and adenosylhomocysteine, suggesting a link between gut microbial activity and brain neurochemistry.
Bacteria in the gut break down food into small chemicals that enter the bloodstream and reach the brain, where they change the levels of key brain molecules involved in energy use and gene control, leading to altered brain function.
What the research says
1 studyIn rats, when they drank a certain kind of milk, scientists found that chemicals from gut bacteria in their urine were linked to changes in brain chemicals — showing that the gut and brain might talk to each other through these tiny molecules.
