Ayurvedic Medicine?

On my way to the farm I caught a very interesting radio program on the People's Pharmacy.  It was about how what you eat is what you are or letting your food be your medicine.  The guest who is a practitioner of ayurvedic medicine and a neurologist, was mentioning that what you eat changes your gut bacteria.  That is simple enough, however she then went on to state that your gut bacteria then send signals to your brain to create desires in what you eat.  So depending upon what you have been eating and what is living in your gut you might be creating a feed back loop that could either be beneficial or downward spiraling.  I still don't know much about ayurvedic medicine but it makes a bunch of sense that our eating habits can have big consequences or payoffs.  Here is a link to the program if you would like to give it a listen.  http://www.peoplespharmacy.com/2016/04/21/show-1033-how-to-stay-healthy-with-principles-of-ayurvedic-medicine/
