Thanks for the citation of the scholarly article. I'll try to access it.
I agree that access to journals are limited unless paid so studying their methodology and results would be tough. The research was published in the journal Molecular Psychiatry under “The Microbiome-Gut-Brain Axis During Early-Life Regulates the Hippocampal Serotonergic System in a Sex-Dependent Manner", so I trust the research done must have been pretty comprehensive for Molecular Psychiatry to approve of their publishing, then being cited in articles featured on S.American, Science Daily, Wall street Journal and even the Economist.
Then again, Science are but theories yet to be disproven. I'm wondering if this above theory is connected to exercise & fitness more intimately.

I found the article you referred to in Scientific American. It is consider a
"soft" science magazine rather than a serious or hard-core scientific journal. From what was written, minimal experiments were performed and certainly not described. Journals, rather than magazines, describe what was done, how it was done and quantitative outcomes. Until I can read this, I place little stock in the findings of this article. To find the article I googled brain intestine connection. Came right up.....this all comes from my statistical background. I guess one of the things that strikes me is that it doesn't matter how much seretonin is in the gut, but how much is in the synapses of the brain cells.
hi you raised an interesting point...none whatsoever offensive..i guess its just different points of view..., if there was any one answer then all problems would be solved.. but i do believe that stress can be the utmost cause in problems concerning the gut,stomach,bowel etc.....
I do agree with the gut connection.
But I believe our whole body is connected. Mind. Body. Soul.
I have had a bad gut since I was a baby. Due to virus? Poor nutrition? Who knows.
All I know is there is a connection between them.
Have you read The Yeast Connection? Good read.
I am no expert. However I found this interesting and have to put my two cents in.
My psychiatrist once told me that there was a study done that shows that the amount of endorphins released in 1 hour of moderate exercise is equal to 1 antidepressant. So exercising to secrete more "feel good hormones" I truly do believe works.
I'm truly sorry if this offends anyone. My post sounds insensitive, reasoning with science and addressing psychological disorders technically. I don't mean to. I know logic doesn't always apply when it comes to the human mind.
The reason why I post this is because I'm trying to prevent ever falling back into the abyss. I used to have depression. It was so bad that I hurt the people I love for years. I never want to go back. I'm just trying to understand more deeply, especially my condition so I don't hurt anyone again.
