Introduction
Environmental toxins surround us, with mercury being particularly dangerous. This mineral “binds easily to fatty tissue especially in the kidneys, liver, and brain,” and selenium serves as an effective detoxifying agent to prevent accumulation.
How Are We Exposed to Mercury?
Mercury contamination stems from multiple sources beyond industrial pollution. According to research, “mercury cell chlor-alkali chemicals are used in the manufacturing of food color additives such as FD&C Yellow 5, FD&C Yellow 6 and high fructose corn syrup.” Additional sources include fish, vaccinations, processed foods, and dental amalgam fillings.
Selenoprotein enzymes incorporate selenium into proteins, functioning as antioxidants that destroy free radicals and stimulate thyroid function. However, when mercury binds to selenium, selenoprotein production diminishes, promoting immune dysfunction.
Selenium Is a “Mercury Magnet”
Selenium demonstrates powerful binding affinity for toxic agents. When mercury and selenium combine, “this new compound cannot be absorbed by the body so it is removed as waste.” Experts recommend consuming up to 1000 mcg daily to counteract mercury contamination.
The Anti-Inflammatory Roles of Selenium
Selenium reduces inflammation, regulates immune response, and improves blood flow. It suppresses NF-kappaB activity (which triggers chronic inflammatory responses) and decreases L-selectin concentrations. Additionally, selenium supports fertility by incorporating into sperm mitochondrial structures.
How Selenium Fights Cancer
Selenium functions like a mechanic, binding “protective antioxidants like glutathione to areas of DNA that need repair.” Research demonstrates selenium stimulates apoptosis in cancer cells and reduces metastasis in melanoma.
Selenium Deficiency Linked to Thyroid Cancer
Low selenium correlates with increased thyroid cancer risk. The FDA recognizes selenium’s “pivotal role in carcinogenesis” through DNA repair mechanisms that inhibit tumor development.
Recommendations for Selenium Consumption
Daily intake should range from 200-400 micrograms, though typical Americans consume only 60 mcg. Deficiency associates with chronic fatigue, high cholesterol, liver disorders, and cancer.
Reduce Your Exposure to Mercury
Certain fish contain higher selenium than mercury concentrations, including tuna, southern flounder, and wild Pacific salmon (Sockeye, Coho, Chinook). Avoid shark, tarpon, and pilot whale.
Highest Sources of Selenium in Food:
- Brazil nuts: 50-75 mcg per nut (6 nuts sufficient for daily needs)
- Pasture-raised eggs
- Mushrooms
- Shellfish
- Meat and organ meats
- Seeds
