The Claim
The composition of gut microbiota has minimal impact on the total daily production of fermentation products but significantly affects the relative proportions of specific fermentation products, such as butyrate and lactate, which differ markedly among individuals based on their microbial community structure.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Your gut bacteria don’t change how much waste they produce overall, but they do change what kinds of waste chemicals—like butyrate and lactate—are made, and this mix is different for everyone depending on their unique gut bug lineup.
See the scientific wording
Gut microbiota composition has little effect on the total amount of fermentation products generated daily but strongly influences the relative proportions of specific fermentation products such as butyrate and lactate, which vary significantly across individuals with different microbial community structures.
What the research says
1 studyStudy: Quantifying the varying harvest of fermentation products from the human gut microbiota
The study shows that while everyone's gut bacteria make about the same total amount of fermentation products, the kinds of products—like butyrate or lactate—depend a lot on which bacteria are present.
