260: Reprogramming Your Microbiome - Is "L. retueri" the Missing Link? - William Davis, MD

On Air with Ella podcast 260



Our guts are home to millions of microbes. These microbes help our bodies do important tasks like digesting food, fighting diseases and making vitamins. The type of microbes present in our gut depends on factors like diet, the use of medications, and sanitation practices. Research shows the diversity of the microbes living in our gut is decreasing, especially as countries become more developed. (For example, stool samples from rural Papua New Guineans contain an additional 50 species not found in people living in the United States.)

What has caused the disappearance of L. retueri is currently unknown. However, it is known that in order to help this species to grow specific types of carbohydrates need to be consumed. People in North America eat much less of these carbohydrates compared to Papua New Guineas. Examples of foods containing these carbohydrates include yams, beans, and artichokes. It may be possible for L. reuteri to live in the human gut if it is taken as a probiotic and a diet containing the types of foods which helps it grow is eaten. Furthermore, if L. reuteri can be re-established, it may have beneficial effects on how our immune system works. - "Rewilding the Human Gut: Reintroduction of the Species Lactobacillus Reuteri" Clinic Trials Summary

Author and researcher Dr. William Davis brought us the Wheat Belly books, and he's back with more ground-breaking information on gut health, restoring our microbiome, and how we can help ourselves in this age of constant disruption and deterioration by replacing microbes nearly completely lost within all modern people. We discuss:

  • What is L. reuteri and how can it help restore our "Super Gut"

  • Why and how we need to reintroduce our bodies to the microbial species that once lived in our ancestors

  • How does restoring lost microbes transform our health when it comes to aging

  • How does restoring lost microbes increase oxytocin levels

  • The power of prolonged fermentation; including benefits like healing, immunity boosts, better skin, and more

  • Fermenting your veggies, making your own probiotic juice - easily!

  • Why most commercial products (probiotics, kombucha, etc) are ineffective and what to do instead

The answer to our gut problems isn't found in the latest diet or superfood. We desperately need to reintroduce our bodies to the microbial species that once lived in our ancestors, while pushing back on the army of microbial interlopers that have taken their place. - Dr. Willam Davis
