Gut Bacteria Change Your Brain

I’m very excited to bring you this research study from my friend Dr. Emeran Mayer. It’s a very intriguing report that demonstrates not only how changes in the gut bacteria correlate with irritable bowel syndrome, but, in addition, how these changes in the gut bacteria correlate with the size of various brain areas.

In addition, the authors were able to correlate how the changes observed in the gut bacteria actually linked to early life trauma. This seemingly connected the dots between early life trauma and the observed differences in brain morphology.

I understand this may sound complicated, but hopefully the video will make this more understandable.

    Early life trauma……..can you provide examples? I can’t bring up the research data/study.

      re: I can’t bring up the research data/study.

      It appears to be here, open-access:
      “Differences in gut microbial composition correlate with regional brain volumes in irritable bowel syndrome”

      The research is quite complex. It appears early trauma has been studied in animal models, but the correlation in humans was hard to understand from this study. Keep in mind the sample size. What jumped out at me like a coiled snake was the F B ratio, that is, the firmicutes to bacteroidites ratio. This ratio also tends to be the same in many who are obese, namely, that firmicutes tends to be much more prevalent in those who are obese, or have IBS. A question to consider is are there easy way to increase bacteroidites and decrease firmicutes? There are some suggestions on the internet about this. Looking forward to more articles like this. Thanks!

    So has anyone studied neonates and gut and brain functions?
    This should be a very equal group of people.
    So people who get IBS late in life had childhood trama?

    Need to read the research!

    Who sponsored this research?

    What would be interesting to know is if there was a psychological trauma, not physical, could the same be observed? Say a child loosing a parent in early childhood, or an abusive parent?

      Hi Luc, yes would think psych trauma would affect the microbes even more. I think/know the abusive parent situation all too well, a physical abuse not only affects the body but can have an even more damaging effect on the brain. I found this is to be extremely true with myself. It’s taken years to clear most of the abuse out of my brain yet it seeps out still but I’m able to catch it quicker now.
