Episode notes
Milk Pus Test Reveals Widespread Mastitis
- Most U.S. dairy herds suffer mastitis, raising somatic cell counts in milk well above healthy levels.
- That can translate to a few drops of pus per glass on average, though pasteurization kills the microbes.
Milk Linked To Fewer Parkinson's Neurons
- Multiple large prospective studies consistently link higher milk consumption with increased Parkinson's risk.
- Midlife milk intake correlated with fewer substantia nigra neurons at death, even after removing diagnosed cases.
Galactose As A Plausible Neurotoxin
- Potential mechanisms include pesticide residues, alpha-synuclein contamination, and galactose-induced oxidative brain damage.
- Galactose from lactose breakdown may reach brain levels that induce Parkinson-like cellular changes.
