I was wondering if anyone knows about the scientific data on microbiota and its relationship with the brain, and how it affects mood and mental health? For example if you eat healthy and fill your gut with probiotics it will affect your serotonin, gaba and other chemicals in your brain.
It got me thinking that if it’s true, where does the soul and spirituality play its part in overcoming stress and mental health issues? Am I correct to think it’s a good mixture of both spirituality and gut health?
The reason why I’m asking is because my mate, who is a personal trainer, is being taught by his boss about microbiota and other scientific things. The thing that struck me most was when he said he went through a mini existential crisis after learning this (e.g. something like ‘when I was feeling down in the past was it me or my gut health? Or my lack of gaba etc…’).
It struck me as a materialistic approach to life (whether he knows that or not, I can’t read his mind). I felt like saying "sure the science behind this might be true but it’s not the only key factor of wellbeing in your life’, but I didn’t say anything because I don’t know the whole topic.
