How does iron keep your body healthy?

Iron is essential for producing hemoglobin, a protein in red blood cells that transports oxygen throughout the body. Adequate iron levels help prevent anemia, which can lead to fatigue and weakness. Additionally, iron supports various metabolic processes and is important for immune function, helping the body fend off infections. A balanced intake of iron from dietary sources like red meat, beans, and leafy greens is crucial for maintaining overall health.
