Most diseases are caused or aided by microbes and parasites. Due to antibiotics, steroidal drugs and chemotherapy our natural intestinal bacteria have been damaged and pathogenic microbes, especially fungi and mycoplasmas, are out of control. Commonly babies now become inoculated with pathogens already in the birth canal. Also microbes from childhood vaccinations may still be present, and there tend to be infection foci in root-canal treated teeth and possibly in scars from surgery. All of these greatly weaken our immune system and allow pathogenic microbes to invade the blood and internal organs. Now we become susceptible to frequent infections, autoimmune diseases, allergies, diabetes, heart disease and cancer. Pathogenic microbes are the underlying cause of basically all chronic diseases.
