Ep. 42 The Microbiome: By All Accounts, We’re Bugs

In This Episode

We’re talking microbiomes today. They exist not just in your gut, but all throughout your body! To explore how they work, Neal welcomes Dr. Rodney Dietert to today’s podcast.

Rodney and Neal dig deep into the crucial relationship between microbes and our own genetics.

They discuss the locations of various microbiomes in the human body, the effect of stress on the microbiome, and which foods have the greatest impact on the microbiome’s health.

Rodney and Neal also talk about the immune system’s interaction with microbiota, soil-based bacteria, and the regrowth process when a microbiome becomes depleted. 

Topics Discussed

  • The ratio of microbial cells to human
  • Locations of microbiomes
  • “Routes of exposure”
  • Stress’ effect on the microbiome
  • The interaction with the central nervous system
  • Foods with the greatest impact
  • Immune microbiota interaction
  • The microbiome on your skin
  • Soil based bacteria
  • Effects of depleted microbiomes

All About Rodney Dietert

In 2012 Dr. Dietert introduced a new course at Cornell applying contemplative tools for creative problem-solving. This has blossomed into a variety of new educational programs and workshops.

Dr. Dietert received his education from Duke University (BS degree) and the University of Texas at Austin (Ph.D.) prior to joining the Cornell faculty in 1977.

One of the pivotal experiences that propelled him to a career in science was a summer high school research experience at the University of Arizona in Tucson.

Ironically, Dr. Dietert was trained primarily in genetics but has devoted his career to environmental research aimed at better protecting children and providing them with the best opportunity for a lifetime of good health.
