Heavy metals, like lead, mercury, cadmium and arsenic, are one of our biggest health problems. Used to manufacture many common products, they’re now found throughout our air, water and food. Virtually all of us harbor toxic heavy metals in our bodies.Heavy metals bioaccumulate, so even small exposures add up over time, triggering problems like heart disease, thyroid disease, dementia, neurological disease and birth defects. Tiny amounts of mercury have been shown to damage the brain of a developing fetus or child.Heavy metals cause problems by displacing other minerals needed for essential body functions. For example, cadmium can replace zinc in key enzymes, causing those enzymes to malfunction so critical biological functions can’t be performed.Many physicians use chelation to remove heavy metals—a “chelating agent” is ingested that binds with heavy metals and carries them out of the body through urine and/or feces. Chelation therapy is especially recommended, and has often been a “m…
