The Thyroid and Aluminium

What is Aluminum?

  • Definition: Aluminum is a lightweight, silvery-white metal that is abundant in the Earth's crust. It is used in various industries, including packaging, construction, and pharmaceuticals.

  • Sources: Aluminum is commonly found in cookware, foil, canned foods, baking powder, antiperspirants, vaccines, and drinking water.

What Types of Aluminum are There and What Do They Do?

  • Aluminum Compounds: Found in antacids, food additives, and deodorants. They can be ingested, absorbed through the skin, or inhaled.

  • Elemental Aluminum: Rarely encountered in its pure form but used in industrial applications.

  • Aluminum Salts: Used in water treatment, cosmetics, and medications, often as stabilizers or preservatives.

Daily Load for Aluminum

  • No Biological Requirement: Aluminum is not an essential nutrient for human health. There is no recommended daily allowance (RDA) for aluminum.

  • Tolerable Intake: The World Health Organization (WHO) suggests a provisional tolerable weekly intake of 2 mg/kg body weight.

What Does Aluminum Do in Our Body?

  • Accumulation: Aluminum has no known biological function. It tends to accumulate in tissues such as the brain, liver, bones, and thyroid.

  • Potential Toxicity: Excess aluminum exposure has been linked to oxidative stress, neurotoxicity, and endocrine disruption.

Symptoms of Aluminum Deficiency

  • Not Applicable: Aluminum deficiency does not occur, as it is not required for any physiological processes.

What Does Aluminum Do for Our Thyroid Pathway?

  • Disruption: Aluminum can interfere with iodine uptake, a crucial element for thyroid hormone production, leading to potential hypothyroidism.

  • Oxidative Stress: Aluminum exposure increases oxidative damage to thyroid cells, which may impair thyroid function over time.

What Does Aluminum Do for Our Liver?

  • Toxin Processing: The liver works to detoxify and eliminate aluminum. Chronic exposure can burden the liver, potentially leading to inflammation or reduced detoxification efficiency.

  • Storage: In cases of excessive exposure, aluminum may accumulate in the liver, contributing to cellular damage.

What Does Aluminum Do for Our Gut?

  • Microbiome Disruption: Aluminum may alter gut bacteria, impacting the balance of beneficial and harmful microbes.

  • Absorption Issues: Aluminum can interfere with the absorption of essential nutrients like calcium and iron.

Physical Ailments That Affect Aluminum

  • Kidney Disease: Impaired kidney function reduces the body’s ability to excrete aluminum, leading to accumulation.

  • Osteomalacia: Excess aluminum can inhibit calcium absorption, weakening bones.

  • Neurological Disorders: Chronic aluminum exposure has been linked to conditions like Alzheimer’s and Parkinson’s disease.

Food That Impacts Aluminum

  • High-Aluminum Foods: Processed foods, baked goods made with aluminum-containing baking powder, and foods cooked in aluminum foil.

  • Acidic Foods: Tomato-based dishes, citrus, and vinegar-containing foods can leach aluminum from cookware.

Medications That Impact Aluminum

  • Antacids: Many antacids contain aluminum hydroxide, which can contribute to aluminum accumulation with prolonged use.

  • Vaccines: Some vaccines contain aluminum as an adjuvant to boost immune response.

  • Deodorants: Aluminum-based antiperspirants can be absorbed through the skin.

Natural Supplements That chelate Aluminum

  • Chelators: Supplements like EDTA can mobilize aluminum in the body, increasing its circulation before elimination.

  • Silica Supplements: Silica may bind to aluminum, aiding in its excretion but also temporarily raising blood aluminum levels.

Heavy Metals That Impact Aluminum

  • Lead and Mercury: These metals compete with aluminum for detoxification pathways, potentially exacerbating aluminum toxicity.

  • Cadmium: Concurrent exposure may increase oxidative stress and compound toxicity.

Testing for Aluminum

  • Urine Test: Measures excreted aluminum to assess recent exposure.

  • Blood Test: Indicates current levels of aluminum in circulation.

  • Hair Analysis: Reflects long-term exposure but may not be as reliable.

  • Tissue Analysis: Used in severe cases to assess aluminum accumulation in organs.

Nutrients Required for Aluminum to be Excreted

  • Not Beneficial: The body does not require aluminum, and minimizing absorption is preferred.

  • Competitors: Adequate intake of calcium, magnesium, and zinc can reduce aluminum absorption by competing for absorption sites in the gut.

Sources of Aluminum in Everyday Life

  • Food:

    • Processed foods and baked goods with aluminum-containing additives.

    • Beverages in aluminum cans.

    • Packaged snacks with aluminum-based stabilizers.

    • Foods cooked or stored in aluminum foil.

  • Cookware:

    • Aluminum pots and pans.

    • Baking trays and utensils.

  • Medications and Healthcare:

    • Antacids containing aluminum hydroxide.

    • Vaccines with aluminum-based adjuvants.

    • Over-the-counter pain medications with aluminum compounds.

  • Personal Care Products:

    • Aluminum-based deodorants and antiperspirants.

    • Cosmetic products like lipsticks and foundation containing aluminum.

  • Household Items:

    • Aluminum foil and wraps.

    • Aluminum cans and containers.

  • Environmental Sources:

    • Drinking water treated with aluminum salts.

    • Industrial emissions and pollution.

    • Dust and soil in aluminum-rich areas.

  • Workplace Exposure:

    • Aluminum smelting and manufacturing facilities.

    • Construction materials containing aluminum.

  • Other:

    • Tetra packs and food packaging.

    • Coffee pod shells

    • Tobacco smoke (contains aluminum particles).

    • Some herbal teas and baking powders with aluminum-based compounds.

Other Random Information About Aluminum

  • Environmental Sources: Aluminum is present in soil, water, and air. Inhalation exposure occurs in industrial settings or areas with high pollution.

  • Chelation Therapy: Treatments like silica-rich water or specific chelators can help reduce aluminum levels in the body.

  • Thyroid-Specific Concern: Chronic aluminum exposure may mimic or exacerbate autoimmune thyroid conditions like Hashimoto's thyroiditis by triggering an immune response.

  • Reducing Exposure: Avoid cooking acidic foods in aluminum cookware, use aluminum-free deodorants, and choose filtered water.
