Mindsip insights from this episode:
Avoid nicotine to preserve gut microbial diversity
Chronic nicotine exposure, even from pouches, has been shown to decrease overall microbial diversity, which is critical for a resilient gut.
Utilize swallowable lab-on-a-chip for advanced gut testing
Emerging technology includes a swallowable, pH-activated 'lab-on-a-chip' pill that can collect samples from multiple locations along your gastrointestinal tract.
Avoid milkshakes to prevent inflammatory endotoxin absorption
Combining fats and sugars, like in a milkshake, is particularly bad as it creates a vector for inflammatory endotoxins (LPS) to be absorbed into your body.
Utilize digital twin to personalize health interventions
Using a 'digital twin,' it's possible to simulate how interventions will affect your unique microbiome to generate rank-prioritized, personalized recommendations.
Eliminate pathogenic microbes before repopulating gut with probiotics
To improve gut health, it may be more advantageous to first eliminate pathogenic microbes to create space before adding beneficial probiotics.
Recognize risks of resilient microbiome in unhealthy gut
A highly resilient microbiome is a negative trait if your gut is in an unhealthy state, as it will be much harder to change and improve.
Scoop stool for accurate gut testing results
For accurate gut testing, it is better to provide a pea-sized scoop of stool rather than using swabs or wipes, which can yield unreliable and contaminated samples.
Recognize appendix as vital reservoir for gut microbiome
Your appendix serves an important role as a reservoir for your core microbiome, helping to reinoculate your gut after a disruption like taking antibiotics.
