Human Gut Microbiota from Autism Spectrum Disorder Promotes Symptoms in Mice [pdf] (cell.com)

In my opinion, this is too preliminary to deserve attention

Is the autism rate different to populations with non western diets and medicine?

Good to see the gut-brain connection getting much needed attention, and some preliminary results. We could see some interesting natural therapies for mental health issues, and even mood regulation for anyone needing it.

Given the complexity of the microbiome and individual variance, it is not going to come easy or anytime soon.
