The manufacturer of the prebiotic Bimuno teamed up with the Dept. of Psychiatry at the University of Oxford to demonstrate the effects of prebiotics on both the gut and brain.
They fed reds either FOS or Bimuno. Both produced effects on the neuronal biochemistry of the rats. Rats who were fed prebiotics (multiple times) saw BDNF (Brain Derived Neurotrophic Factor) increase. Rats who didn't receive probiotics did not see this increase.
Likewise, components of NMDA (a receptor that's important for brain development, learning and memory) increased in the rats who were fed priobiotics - after just two weeks.
Studies done with humans in late 2013 will have published results soon.
It's just more evidence linking the gut and the brain (and more reasons to eat yogurt!).
Here's what I read:
