Gut instincts: The secrets of your second brain (2012)

Cheap gene sequencing has spurred an explosion of research on the bacterial flora in your gut and its links with various diseases and disorders. (Obesity, mood disorders, irritable bowel/Crohn's, I forget what else.)

There's a Coursera class in progress on this right now (https://class.coursera.org/microbiome-001/) run by Rob Knight at UC Boulder. Another interesting thing to look at is the American Gut (http://americangut.org/) project, which will analyse a sample of your gut bacteria for $100.

I've long since discovered what a large impact specific diets have on my mood, depression and well-being. I ordered a gut sampling from uBiome last week and am looking forward to having measurements to manage.

I wonder if this has anything to do with the effectiveness of the ketogenic diet to treat epilepsy.
