Why iron is important for seniors
Iron is a vital mineral that supports growth, repair, and overall health. While it is the second most abundant metal on Earth, making up about 80% of the planet’s inner and outer cores, its role in the human body is critical and highly specialized.
One of iron’s main functions is to form hemoglobin, a protein in red blood cells that transports oxygen from the lungs to tissues throughout the body. Without sufficient iron, the body cannot produce enough healthy red blood cells, leading to iron-deficiency anemia. Symptoms of low iron include fatigue, weakness, and reduced physical endurance, which can affect daily activities and quality of life.
Iron also supports the immune system by helping produce white blood cells that fight infections, making adequate intake important for overall health. Seniors are recommended to consume approximately 8 milligrams of iron per day. Good dietary sources include lean meats, poultry, seafood, dried fruits, and beans, which provide iron in forms the body can absorb efficiently. Supplements may be necessary if dietary intake is insufficient, though they should be used carefully.
Excess iron can be harmful. High levels may cause constipation, diarrhea, vomiting, and can promote the growth of bacteria and parasites, since these microorganisms also use iron to thrive. The body naturally loses small amounts of iron in urine and feces, a loss that is greater in menstruating women due to monthly blood loss.
Maintaining the right balance of iron, through a healthy diet and appropriate supplementation when needed, is essential for energy, immunity, and overall well-being, particularly in seniors who may face dietary limitations or chronic health conditions.
