10% Human: how your bodies microbes hold the key to health and happiness, by Alanna Collen

Here's a startling fact - for every one of the cells that make up your body, there are another nine living on or mostly inside you.  These microbes have a very complex relationship with us, their host organisms.  Without them, we would not be able to digest a good portion of our food, we would lose out on important vitamins and enzymes that they produce, and would also lose much of our immune system.  While I was mostly acquainted with the basics of the role of these microbes in digestion, Collen also summarizes recent research on the links between these microbes, antibiotics, and other illnesses or disorders such as obesity, autism and even personality traits such as anxiety and other moods.  Collen turns the 'you are what you eat' statement around to 'you are what they eat' and describes the widespread effects of various imbalances of microbes on human health.  So, if you want to have better health and boost your immune system, eat what your microbes prefer - lots of good fruits and vegetables.  304 pages.  Medical .
