Ep. 3: Gut and Digestion Part 2: Ideal Foods For Our Gut

Listen to the podcast on Apple Podcasts | Google Play | Stitcher| Spotify

In this episode we discuss:

  • ​How plant polyphenols shape our gut microbiome
  • ​Potential issues with fruits (and why fructose isn’t one of them)
  • ​Why fats are essential for proper gut function and potential issues with low-fat diets
  • ​The importance of the migrating motor complex for a healthy gut and its relationship with our metabolic function
  • ​Why low-carb, keto, carnivore, and fasting (including intermittent fasting) aren’t ideal for our guts

​2:43 – the effects of plant antimicrobials and polyphenols on the gut

​8:35 – potential issues with fruits

15:20 – the effects of fats on our guts

​21:59 – the importance of the migrating motor complex

28:40 – the effects of low-carb, keto, carnivore, and fasting (including intermittent fasting) on our guts

    So for this case, what best protocols do you know for reducing SIBO and/or toxic microbiome? Would a periodical carnivore diet (to kill / reset the toxic microbiome) and then shift to bio-energetic diet would make sense (makes to me) ?

      Often a temporary starvation of the gut microbes (like with low-carb diets or fasting) doesn’t kill them and the issue returns as soon as carbs are reintroduced. Instead it’s important to start by supporting your metabolism which will in turn restore proper gut function, which can sometimes be enough to resolve the issue on its own. If not then at that point it can be helpful to use various antimicrobials for SIBO or other gut dysbioses. There are a ton of different antimicrobials that can be used, including monolaurin, various essential oils and herbs, spore-based probiotics, prescription antimicrobials, etc., and often combinations of the various antimicrobials are most effective.
