Fluoride has been what many dentists have recommended for clean, healthy, white teeth for many years, but is it all it is cracked up to be. Fluoride is found in our toothpaste, mouthwash, gels, foams, varnishes, creams, in our drinking and ground water, soil, vegetables and fish. Research has shown that fluoride intake negatively affects numerous organs and physiological processes, including the bones, thyroid, the cardiovascular system, kidneys, liver, breast, and immune and reproductive function. Numerous studies indicate that fluoride affects these organs and physiological processes by inducing free radical production resulting in oxidative damage. This is also apparent in the association between cancer rates and fluoridation of water supplies.
The thyroid is one of the glands affected by fluoride intake. Studies show that prolonged consumption of drinking water with elevated levels of fluoride caused an increase in thyroid stimulating hormone (TSH) released from the pituitary, decreased levels of T3, and more intense absorption of radioactive iodine by the thyroid compared to healthy individuals who consumed drinking water with the normal fluoride concentrations. In another study researchers found that chronic exposure to fluorine resulted in immune deficiency in all workers inhibiting their bodies ability to fight infections. Several studies have shown that fluoride is a key factor in reduced fertility and declining health of spermatozoa (resulting in reduced sperm count, motility, and density).
Fluorisis, or increased fluoride exposure can damage the cardiovascularsystem . Researchers have shown that subjects with increased fluoride
intake have global heart dysfunction and left ventricular diastolic dysfunction, meaning the heart does not relax properly. Additionally, fluoride
can cause abnormalities in the elasticity of the aorta, the primary blood vessel leading from the heart.
Fluoride is an ubiquitous chemical compound, which has both beneficial and adverse effects on health, with a narrow range between the intakes at which this occurs. Supplementation with iodine and other trace minerals can compete with fluoride and reduce the impact of excessive fluoridation on physiological processes in the body.
