“Know Thyself: Quantifying Your Human Body and Its One Hundred Trillion Microbes” Understanding Cultures and Addressing Disparities in Society: Degrees of Health and Well-Being Public Lecture Series University of California, San Diego January 20, 2016 Dr. Larry Smarr Director, California Institute for Telecommunications and Information Technology Harry E.

Abstract To truly understand the state of the human body in health or disease, we now realize that we must consider a much more complex system than medical science considered heretofore. This is because we now know that the human body is host to 100 trillion microorganisms, ten times the number of cells in the human body and these microbes contain 300 times the number of DNA genes that our human DNA does. The microbial component of our “superorganism” is comprised of hundreds of species with immense biodiversity. Exponential decrease in the cost of genetic sequencing has enabled scientists to finally "read out" the nature of the changes in the microbial ecology in people in health and with disease. In addition, researchers have traveled to remote sites to measure the difference between the microbiome of indigenous people and those of Western cultures. These differences turn out to be profound, pointing to a gap of "missing microbes" in our Westernized societies. To put a more personal face on the “patient of the future,” I have been collecting massive amounts of data from my own body over the last five years, which reveals detailed examples of the episodic evolution of this coupled immune-microbial system. As similar techniques become more widely applied, we can look forward to revolutionary changes in medical practice over the next decade.

Why Did I Have an Autoimmune Disease like Crohn’s Disease? Despite decades of research, the etiology of Crohn's disease remains unknown. Its pathogenesis may involve a complex interplay between host genetics, immune dysfunction, and microbial or environmental factors. --The Role of Microbes in Crohn's Disease Paul B. Eckburg & David A. Relman Clin Infect Dis. 44:256-262 (2007) I Have Been Quantifying All Three

We Have Much to Learn from Indigenous Peoples “Our work emphasizes the value of deep characterization of microbiomes of people living ancestral life-styles, particularly if practices in industrialized societies might eradicate potentially beneficial microbes and their encoded functions.” “The average Yanomami's microbiota had twice as many genes as that of the average US person.”

There is a Huge New Field of Products Coming Which Enable You to “Garden” Your Microbiome “I would like to lose the language of warfare,” said Julie Segre, a senior investigator at the National Human Genome Research Institute. ”It does a disservice to all the bacteria that have co-evolved with us and are maintaining the health of our bodies.” Will Medical Foods Provide New Tools for Altering Gut Microbiome?
