Iron-rich foods are essential for maintaining healthy levels of iron in the body, which is crucial for producing red blood cells. Common sources include red meat, poultry, and fish, which provide heme iron, a type that is easily absorbed by the body. Plant-based sources, such as beans, lentils, and spinach, contain non-heme iron, which is less readily absorbed but can still contribute to overall iron intake. To enhance iron absorption from non-heme sources, it's beneficial to consume them with vitamin C-rich foods like citrus fruits or bell peppers. Additionally, cooking in cast iron cookware can increase the iron content of food. A balanced diet that includes a variety of these foods can help prevent iron deficiency.
