The Good:
Iron from food comes in two forms: heme and non-heme. Heme is found only in animal flesh like meat, poultry, and seafood. Non-heme iron is found in plant foods like whole grains, nuts, seeds, legumes, and leafy greens. Non-heme iron is also found in animal flesh (as animals consume plant foods with non-heme iron) and fortified foods.
Iron is stored in the body as ferritin (in the liver, spleen, muscle tissue, and bone marrow) and is delivered throughout the body by transferrin (a protein in blood that binds to iron). A doctor may sometimes check blood levels of these two components if anemia is suspected.
- Oxygen Transport: One of the primary functions of iron is to help transport oxygen throughout the body. Hemoglobin, a protein in red blood cells, contains iron and binds to oxygen in the lungs. This oxygenated hemoglobin is then carried by the bloodstream to all the body's tissues, where it releases oxygen for use in cellular respiration. This process is essential for energy production and overall bodily function.
- Energy Production: Iron is necessary for the production of adenosine triphosphate (ATP), which is the primary energy currency in the body. It is required for various metabolic processes, and without adequate iron, your body may experience fatigue and weakness.
- Cognitive Function: Iron is important for brain health and cognitive function. It helps with the development and maintenance of healthy brain cells, and iron deficiency can lead to cognitive impairments, especially in children and pregnant women.
- Immune System Support: Iron is involved in the proper functioning of the immune system. It helps the body defend against infections and diseases by supporting the production and activity of immune cells.
- Collagen Production: Iron is a cofactor in the production of collagen, a protein that plays a crucial role in the health of your skin, blood vessels, and connective tissues.
- Detoxification: Iron is involved in the detoxification of certain compounds in the body, helping to eliminate harmful substances.
- Hormone Synthesis: Iron is needed for the synthesis of some hormones, including those related to growth and development.
Into The THICK Of It
- Organ Damage: Iron overload can lead to the accumulation of iron in various organs, especially the liver, heart, and pancreas. This can cause damage to these organs over time, potentially leading to conditions like cirrhosis, heart problems, and diabetes.
- Joint Pain: Excess iron can also accumulate in the joints, causing pain and discomfort.
- Skin Changes: Some people with iron overload may develop a condition called "bronze diabetes", which causes a bronze or gray-ish tint to the skin.
- Fatigue: Iron overload can lead to chronic fatigue and weakness.
- Increased Infection Risk: High levels of iron in the body can promote the growth of harmful bacteria and increase the risk of infections.
- Cognitive and Mood Changes: Some individuals with hemochromatosis experience cognitive changes, including memory problems and mood swings.
- Endocrine Disorders: Excess iron can affect the endocrine system, leading to conditions such as hypothyroidism and decreased testosterone production in men.
- Complications in Other Conditions: Iron overload can worsen the prognosis in certain conditions like chronic liver disease, hepatitis C, and alcoholism.
Thyroid Function
- Hypothyroidism: Iron overload may lead to an underactive thyroid, a condition known as hypothyroidism. In cases of iron overload, excess iron can accumulate in the thyroid gland, impairing its ability to produce thyroid hormones. This can result in symptoms such as fatigue, weight gain, cold intolerance, and cognitive changes. People with hypothyroidism due to iron overload may require treatment with thyroid hormone replacement therapy.
- Autoimmune Thyroid Diseases: Excess iron in the body has been associated with an increased risk of autoimmune thyroid diseases, including Hashimoto's thyroiditis. Autoimmune thyroid diseases are characterized by the immune system attacking the thyroid gland, leading to inflammation and a decrease in thyroid hormone production. Iron overload can potentially trigger or exacerbate these autoimmune conditions.
- Thyroid Function Regulation: Iron plays a role in the regulation of thyroid hormones. Excess iron can disrupt the normal feedback mechanisms that control the release of thyroid hormones, leading to imbalances in the levels of thyroid hormones in the body.
- Thyroid Medication Interference: Iron supplements and high dietary iron intake can interfere with the absorption of thyroid medications, such as levothyroxine. Taking iron supplements or consuming iron-rich foods close to the time of taking thyroid medication can reduce its effectiveness.
