In this video Naturopath and Clinical Nutritionist David J. Getoff explains how we develop life-long immunity to infectious diseases by first getting them, and then recovering from them! He explains:
• Children get immunity from the mother from birth going through the vagina.
• More immunity is created as the child breast-feeds.
• As the child is exposed to various bacteria in his or her environment, the immune system identifies it and develops immunity to it if it is pathogenic.
• It's not required to have a perfectly clean house or area; it's not about avoiding the "bad bacteria" but rather it's about having a properly functioning immune system so that the body can identify and properly deal with any "bad bacteria."
