Episode notes
Sunlight Shapes Mitochondria Gut And Health
- Modern chronic disease stems from human separation from sun-rich environments and low vitamin D altering mitochondria and the gut microbiome.
- Joel Gould links mitochondria to light sensing, saying sun exposure increases ATP and overall cellular energy, not just vitamin D production.
Joel Attributes His Weak Chin To Childhood D Deficit
- Joel shares his own facial profile with a weak chin, missing second molars and wisdom teeth as epigenetic results of childhood D3/K2 deficiency.
- He ties his craniofacial traits to growing up far north with low sun and fat-soluble vitamin lack.
D3K2 Drives Jaw Growth And Airway Size
- Vitamin D and K2 regulate calcium and facial/jaw development, affecting airway size and dental crowding.
- Joel invokes Weston A. Price showing processed diets and fat-soluble vitamin deficits cause collapsed arches and poor dental development.
