Dr. Lorraine Day, former chief of orthopedic surgery at San Francisco General Hospital, challenges mainstream medical approaches while discussing mad cow disease and prion transmission. Having reversed her own advanced cancer through natural therapies rather than chemotherapy and radiation, Day questions conventional treatment protocols. She explains that mad cow disease, or bovine spongiform encephalopathy, has been known to government since 1976 and spreads through feeding rendered animal parts to herbivorous livestock. The disease-causing prions cannot be destroyed even by incineration, raising concerns about aerosol transmission and environmental contamination. Day argues that factory farming practices, including confining animals in pens and feeding them meat despite their vegetarian nature, suppress immune systems and create conditions for disease. She controversially suggests that prions are not the cause but rather the result of animals with dead and dying tissue from unnatural raising practices, challenging the germ theory itself and advocating for natural immunity.
