Fluoride depletes the energy reserves and the ability of white blood cells to properly destroy foreign agents by the process of phagocytosis. As little as 0.2 ppm fluoride stimulates superoxide production in resting white blood cells, virtually abolishing phagocytosis. Even micro-molar amounts of fluoride, below 1 ppm, may seriously depress the ability of white blood cells to destroy pathogenic agents. Fluoride confuses the immune system and causes it to attack the body's own tissues, and increases the tumor growth rate in cancer prone individuals. Fluoride inhibits antibody formation in the blood.
Fluoride depresses thyroid activity.
Fluorides have a disruptive effect on various tissues in the body. Fluoride promotes development of bone cancer. Fluorides cause premature aging of the human body. Fluoride ingestion from mouth rinses and dentifrices in children is extremely hazardous to biological development, life span and general health. The contents of a family size tube of fluoridated toothpaste is enough to kill a 25 pound child.
