Iron is an essential mineral required for various bodily functions, including oxygen transport, red blood cell production, and energy metabolism. The human body cannot produce iron on its own, so it must be obtained from external sources, primarily through diet.
Among the various dietary sources of iron, red meat, particularly organ meats such as liver, is considered the richest source of heme iron. Heme iron is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Other good sources of heme iron include poultry, fish, and eggs.
