| 0:00.0 | Hello, my dear podcast listener. |
| 0:02.0 | In this episode, I speak with doctors Justin and Erica Stonenberg, who run a lab at Stanford |
| 0:06.4 | researching the nuances of 100 trillion or so tiny bacteria that inhabit the gut in numbers |
| 0:11.8 | that exceed that of even your own cells, and do much to affect your health. |
| 0:16.6 | We discuss the pivotal role fire plays in fueling good bacteria in the gut to produce compounds |
| 0:21.2 | that regulate the immune system, including increasing the number of T regulatory cells, which |
| 0:26.4 | are specialized types of immune cells that keep the immune system in check and prevent |
| 0:30.7 | autoimmune responses, and how these compounds also increase other types of blood cells in |
| 0:35.6 | the body in a process known as hematopoesis. |
| 0:38.8 | We also talk about how the lack of fiber in the typical American diet actually starves |
| 0:43.5 | these good bacteria of their food. |
| 0:45.7 | This has an effect not only on the immune system and autoimmune diseases, but also results |
| 0:50.7 | in the breakdown of the gut barrier, which leads to widespread inflammation and inflammatory |
| 0:56.2 | diseases. |
| 0:57.1 | Is some of this sounding familiar? |
| 0:59.1 | That's because I also talk a bit about some of this with Dr. Mark Scheginaga in a recent |
| 1:04.0 | podcast called Corybar, Micronutrients, Fiber, and Polyphenols in a bar. |
| 1:09.4 | So make sure to check that out also on iTunes. |
| 1:13.3 | Lastly in this podcast, Dr. Erica Stonenberg talks about how C-sections have a negative effect |
| 1:19.8 | on infants' gut due to the lack of exposure to bacteria present in the mother's vaginal |
| 1:25.3 | canal and how the use of formula deprives the infant not only of the good bacteria present |
| 1:31.5 | in mom's gut, but also from specialized carbohydrates and breast milk that are good |
