In this episode, Dr. William Davis delves into the fascinating world of L. Reuteri and its impact on skin health, gut and overall well-being. Learn about the potential benefits of this probiotic strain and its connection to gut health.
Topics Covered :
L. Reuteri and its Benefits:
- Loss in Modern Populations: Dr. William Davis highlights that Lactobacillus reuteri is largely absent in modern people due to antibiotic overuse, unlike in indigenous populations and wild mammals [ 01:16 ].
- Initial Benefits: Restoration of L. reuteri can lead to youthful musculature, increased oxytocin (enhancing love and affection), improved libido, and better social behavior [ 02:07 ].
- Skin Health:
- L. reuteri dramatically increases dermal collagen, reducing wrinkles [ 02:31 ].
- A clinical trial with 25 women showed a 15% increase in dermal layer thickness using L. reuteri with marine collagen peptides, hyaluronic acid, and astaxanthin [ 03:33 ].
- Participants experienced more moisture and reduced wrinkle depth [ 05:19 ].
- Body Composition: The same trial unexpectedly showed significant waist circumference reduction, suggesting a targeting of abdominal fat and restoration of youthful muscle [ 05:31 ].
- Comparison to GLP-1 Agonists: Dr. Davis contrasts the benefits of L. reuteri with the drawbacks of drugs like Wegovy, which can lead to muscle loss and worsened health upon cessation [ 06:30 ].
- Strain Specifics: Dr. Davis mentions using a specific strain, L. reuteri LRDR, in his clinical trials, chosen for its effects in animals and humans [ 09:52 ].
- Dosage: Emerging evidence suggests that dosage matters, with higher doses potentially yielding better results [ 11:33 ].
Mechanisms of Action:
- Endotoxemia Reduction: L. reuteri helps reduce endotoxemia (bacterial breakdown products in the bloodstream), which is linked to various health issues like increased blood glucose, abdominal fat, and inflammation [ 13:39 ].
- Oxytocin and Cortisol: L. reuteri increases oxytocin, suppressing appetite, and reduces cortisol levels, which are linked to abdominal fat accumulation [ 16:54 ].
Other Beneficial Bacteria and Practices:
- Bacillus subtilis: Dr. Davis discusses using Bacillus subtilis to make sparkling juices, utilizing the DE111 strain for CO2 production [ 19:01 ].
- Saccharomyces boulardii: Recommended for minimizing gastrointestinal microbiome disruption when taking antibiotics [ 20:51 ].
- Lactobacillus crispatus: Crucial for female reproductive health, reducing miscarriage risk, premature delivery, and improving vaginal health [ 22:25 ]. It can be obtained through products like Gero Fem Dophilus Advanced or by making yogurt [ 24:38 ].
Prebiotics:
- Role: Prebiotics feed beneficial microbes, leading to the production of metabolites like butyric acid [ 27:38 ].
- Butyric Acid: Improves sleep, lowers blood pressure and sugar, reduces inflammation, and acidifies the skin, discouraging pathogens [ 28:19 ].
- Types: Inulin and fructooligosaccharides are widely metabolized, but other options include galactooligosaccharides, xylooligosaccharides, and polysaccharides [ 33:51 ].
- Hyaluronic acid: It is a fiber sourced from animals that blooms butyric acid producing species [ 34:35 ]
Wheat:
- Modern Wheat Issues: Dr. Davis reiterates the problems with modern high-yield semi-dwarf wheat, including glyphosate exposure [ 37:11 ].
- Differences in Wheat: The type of gliadin protein in wheat varies, affecting gastrointestinal tolerance [ 40:01 ].
- Harmful Components: Amylopectin A, wheat germ agglutinin, and phytates contribute to heart disease risk, gastrointestinal toxicity, and mineral binding, respectively [ 40:23 ].
- Sourdough: Fermentation reduces some harmful components but doesn't eliminate them [ 43:12 ].
Microbiome Research:
- SIBO: Small intestinal bacterial overgrowth is common, and correcting it can be achieved by restoring lost microbes, especially those that colonize the small intestine [ 45:43 ].
- Microbe Interactions: Microbes interact with each other, and understanding these interactions is crucial [ 51:10 ].
Future Directions:
- Oxytocin Release: Further research is needed to understand how L. reuteri causes oxytocin release and its potential to address social isolation and narcissistic behavior [ 52:48 ].
- Shape and Body Composition: Focusing on targeting abdominal visceral fat and restoring muscle, rather than just weight loss [ 54:18 ].
Resources:
- Books: "Super Gut," "Wheat Belly" (revised and expanded), and cookbooks [ 55:53 ].
- Website/Blog: WilliamDavisMD.com William Davis MD [ 49:40 ].
- Membership website: The Inner Circle [ 49:54 ]
One Thing for Gut Health Today:
- Include fermented foods like Bacillus subtilis sparkling juice or sauerkraut [ 56:51 ].
This video explores the potential of L. Reuteri for improving skin health and overall wellness by focusing on gut health. Dr. Davis provides insights into how this probiotic strain may contribute to a healthier you.
