Listen on:

I first became familiar with the brilliant Dr. William Davis and his impressive body of work when I interviewed him for an episode about heart attacks way back in 2009.

Later, he joined me for a podcast about his book “Wheat Belly,” in which we discussed why you're not eating the same kind of wheat your ancestors ate, whether wheat bread is really better than white bread, if wheat is ever OK to eat and if so, when, and good substitutes and alternatives for wheat.

Today, Dr. William Davis is back to discuss his new book Super Gut: A Four-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight. In Super Gut, Dr. Davis takes his research and findings a step further and shows that because of highly-processed diets, pesticides, and overuse of antibiotics, it's likely that your gut is missing many good bacteria required to be healthy. The result is a loss of control over health, weight, mood, and even behavior.

The ancient bacteria that keep your gut in alignment and your digestion easy have been dying off, replaced by harmful microbes that don’t serve to keep you physically healthy and mentally fit. With cutting-edge research, Dr. Davis has connected the dots between gut health and modern ailments and complaints. There are entire species of microbes that have disappeared, creating health issues that were uncommon one hundred, or even fifty, years ago. A major consequence is SIBO (Small Intestinal Bacterial Overgrowth). This silent and profound epidemic affects one out of three people and is responsible for an astounding range of human health conditions.

Super Gut teaches you how to eliminate bad bacteria and bring back the missing “good” bacteria with a four-week plan to reprogram your microbiome. The program is based on research and techniques that not only get to the root of many diseases but improve levels of oxytocin (the bonding/happy hormone), brain health, and promote anti-aging, weight loss, mental clarity, and more restful sleep. Super Gut explains the science clearly and includes more than forty recipes, a diet plan, and resources so you can pinpoint your gut issues, correct them, and maintain your long-term health and well-being. Dr. Davis provides solutions to health problems by addressing the microbiome, massively disrupted in modern people. He shows readers in his Super Gut book, for instance, how to restore important lost microbes such as Lactobacillus reuteri, restored by using a unique method of yogurt fermentation that smooths skin and reduces wrinkles, restores youthful muscle and strength, deepens sleep, reduces appetite, and provides many other youth-preserving and anti-aging effects. He also provides do-it-yourself-at-home strategies for benefits such as improved mood, improved athletic performance, better sleep, heightened immunity, and improved body composition.

Dr. William Davis is responsible for exposing the incredible nutritional blunder made by “official” health agencies: Eat more “healthy whole grains.” Today's wheat is different from the wheat of 1960, thanks to extensive genetic manipulations introduced to increase yield-per-acre. Eliminating wheat yields results beyond everyone's expectations: substantial weight loss, correction of cholesterol abnormalities, relief from inflammatory diseases like arthritis, better mood, and reduced blood sugar, with many type 2 diabetics being freed of insulin and other drugs. Dr. Davis articulates his theories and solutions in his Wheat Belly series of books. He is also a champion of individual self-directed health, as discussed in his Undoctored book.

In this episode, you'll discover:

-The key to healthy bacteria and how Dr. Davis assesses and repairs gut issues…6:30

  • Conventional medicine ignores the negative effects of antibiotics (amoxicillin and penicillin, etc.) affecting the microbiome and says nothing about how to rebuild
  • How different biotics impact the gut, brain health, and cognitive performance
  • Stanford study by Justin and Erica Sonnenburg:
  • Fermented foods like fermented vegetables, kefir, kombucha, and yogurt contain microbes that restore other healthy microbes
  • Microbes like Pediococcus Pentosaceus sets the stage to allow other healthy microbes to persist
  • Fermentation of foods (controlled rotting process) that is good for human health was sidelined with the invention of home refrigeration
  • Viome

-What is L. reuteri and why focus on it?…11:12

  • The lost microbe, L. reuteri
  • L. reuteri is susceptible to antibiotics; mass kill-off of our healthy microbes
  • Effects of modern-day antibacterial
  • Indigenous diets vs. modern diets; indigenous populations and wild animals still have the microbe, while most western populations have lost L. reuteri
  • Oxytocin
  • L. reuteri promotes a surge of oxytocin production, which positively affects:
    • Mood and REM sleep
    • Restoration of muscle and skin
    • Bone density and acceleration of healing
    • Suppression of appetite for snacking
    • Increased drive and testosterone production
  • L. reuteri and cancer
  • BioGaia

-Dr. Davis' reaction when told he cannot make yogurt with L. reuteri…16:15

-How do you make yogurt?…24:55

  • Started with 2 BioGaia strains (DSM 17938 and ATCC PTA 6475)
  • The only strain not used is the 30242 (UAL-RE16)
  • L. reuteri resides in the entire GI tract and produces bacteriocins, natural antibiotics effective against stool microbes like E. coli and Klebsiella (SIBO)
  • AIRE SIBO device breath tester registers hydrogen gas; works for testing SIBO
  • Dr. Aonghus Shortt – developer of AIRE
  • SIBO yogurt recipe
  • Tests in clinical labs capture breath in a vial and tested maybe hours later leads to false negatives
  • Are there ways to combine microbiome to apply effects?
  • BioGaia strains still available on Amazon
  • Only 5 strains are tested at a time because of the cost ($70,000 per batch)
  • Cutting Edge Cultures LR Superfood is also a good source

-What to do once you get the strains?…35:30

-How you ferment yogurt?…39:40

  • Sous Vide slow cooker
  • Reuteri and most lactobacilli are adapted to mammalian temperatures – 97-98°F
  • Can also use a dehydrator, yogurt maker, or instant pot
  • 36-hour fermentation
  • Different microbes prefer different temperatures, but most Lactobacilli and Bifidobacteria prefer human body temperature
  • Spore formers like Bacillus Coagulans prefer 115-122°F to produce yogurt
  • Dr. Davis also makes sparkling juices with the fungus Saccharomyces boulardii
    • Empty a capsule of Florastor probiotic put into a juice without preservatives (which are anti-microbials), set aside for 48 hours
  • Saccharomyces boulardii helps rebuild a healthy microbiome and helps correct the adverse effects of antibiotics
  • Pre-heating milk to 180°F for 20-30 minutes and allow to cool down then adding inulin gets a better texture
  • Use a thickener like guar gum when using coconut milk

-When is the best time to consume yogurt?…45:25

-Using an older batch to seed a newer batch…52:45

  • Use curds or the whey
  • A few hurdles:
    • If you use dairy (whole milk), preheat
    • Half and half, you do not need to preheat
    • Devices with preset temperatures need to be run for 2 hours to verify the temperature
    • Reuteri dies at 108-109°F

-For someone with SIBO, what is a sample daily diet and supplements? Besides the yogurt, what should they be doing and avoiding?…55:20

-Big wins with probiotics…1:02:05

  • Probiotics are helpful, but most only help a little
  • Importance of fermented foods; consume fermented foods with every meal

-And much more…

Dr. William Davis:

    • Lactobacillus Gasseri BNR 17 – colonizes the small intestine and produces up to 7 bacteriocins, a virtual bacteriocin powerhouse
    • Lactobacillus Reuteri DSM 17938 and ATCC PTA 6475 – also colonizes the small intestine and produce up to four bacteriocins, including the powerful Reuterin. (L. reuteri is such an effective antibacterial that a microbiologist with 40 years experience told me that they sometimes clean their bacterial production vats with this microbe. I was skeptical and checked with my friend, Raul Cano, PhD, also with 40 years of academic microbiology experience–yup, he confirmed: L. reuteri can clean vats of unhealthy microbes.)
    • Bacillus Coagulans GBI-30,6086 – produces a bacteriocin. It does not colonize the upper GI tract but has been shown to substantially reduce the symptoms of irritable bowel syndrome that is virtually synonymous with SIBO.

  1. Mo says:

    For Dr Davis: I was very inspired by this podcast, bought your book, reading it voraciously. Also, purchased the BioGaia Osfortis on your recommendation. Do you realize it has maltodextrin? Something you state should be avoided.

  2. Jason B. says:

    This is great info! It references Hydrogen SIBO, what about Methane dominant SIBO? Same SIBO yogurt protocol?

  3. Robert Resz says:

    i suspect i have sibo and I listended to this podcast wondering if but Would the L. reuteri yogurt by itself help with sibo ? It looks like from my short reasearch that the sibo strains have to be sourced separately from different products and companys, and is the instructions for the sibo yogurt the same ? Also i know someone suffering from parkinsons, can the sugar shift product be made into a yogurt to multiply the probiotics ?

  4. Alex Lowery says:

    Thanks for mentioning Sugar Shift and how it has been beneficial for Parkinson’s. I have Parkinson’s due to mold toxicity. I am at the beginning of testing and treatment with a Functional Medicine Doctor, so I’m at the binder phase, getting my bile production moving and sauna for detox. I know gut health will be a part of it and I’ve added Sugar Shift to my wish list for that phase.

  5. Trevor says:

    Hi Ben, great podcast! For those of us who track macros, how do we figure out the estimated macros of the yogurt? Thanks.

    1. Ben Greenfield says:

      this might be a helpful resource: https://bengreenfieldlife.com/article/nutrition-articles/how-to-track-calories/

  6. suzanne says:

    Ben, Davis mentions that Akkermansia is low or missing in 5% of the population and the other 95% have enough. I thought sure I heard Joel Greene say the exact opposite – that 95% of population is low on Akkermansia. I thought I read it in his book also, but darned if I can find it there or on your podcast with him. I don’t want to use the apple peelings, HMO, etc. if we have enough Akkermansia. Can you clarify please?

  7. Joe says:

    Yogurt ingredients:
    BioGaia Gastrus comes in tablets; crush 10 tablets of each strain to a powder. Unless I’m reading the description wrong, the tables contain both strains (DSM 17938/ATCC PTA 6475) Do you use 10 tablets that contain both strains or 20 tablets?

  8. em4life says:

    the universe is fractal in nature. What’s good for the soil, is good for the colon, e.g. Effective Microorganisms (EM)


    I take it with psyllium husk, as a last meal for the gut in the evening. There are “human” versions of EM, but it’s not as effective as the original one. For best effects ferment it yourself.

  9. Tyson Gaylord says:

    can you use raw milk or raw cream?

  10. Lara Butler says:

    One of the reasons I’m such a fan of your Podcast is the availability of transcripts. Words matter! After listening to every minute of it, this Podcast is one of the ones I want to dive into further by reading it with a yellow highlighter in hand. However, I don’t see a transcript link. Will that be coming at a later point? The Show Notes are awesome, by the way, but I still want a transcript!

    1. Ben Greenfield says:

      Hi Lara. The transcript is now available: https://bengreenfieldlife.com/transcripts/transcript-william-davis-podcast/

  11. Chase K says:

    Hi Ben and Dr Davis! I have been waiting for this pod for a minute, thanks for doing this!

    My question is, does having a colectomy leave me at risk of SIBO (I think I already have it) and how does one fix this issue? Without a colon, where does the biome congregate. Will Dr Davis’ yoghurt help with this? Thank so much
