Heavy metals are one of the major toxins you may get exposed to throughout your life. Heavy metals are metals with a density of 5 g/cm3 or more. In large amounts, they have adverse effects on living organisms, on our environment, and weaken immunity. Besides being potentially harmful, they also serve absolutely no beneficial role in the human body.
According to a 2014 study published in the Interdisciplinary Toxicology, some heavy metals interfere with normal biological processes and have toxic effects (12). They bind to proteins in your body that would otherwise be activated by normally occurring minerals like zinc and magnesium. They can cause oxidative stress, chronic inflammation, and cellular interference.
Some common heavy metals that you may encounter include lead, arsenic, mercury, cadmium, and aluminum. Lead can be found in lead-containing paint, contaminated municipal tap water, cosmetics, contaminated food, and tobacco products. Arsenic can be found in pesticides, commercially grown produce, apple juice, rice products, glass work, smelting, and semiconductor production. Mercury can be found in larger seafood, dental amalgam silver tooth fillings, and some vaccines. Cadmium can be found in tobacco, metalworking, soldering, battery manufacturing, and contaminated foods. Aluminum can be found in some vaccinations, antiperspirant deodorant, municipal tap water, canned food and drinks, and some processed foods.
