On the properties of iron

Iron is a mineral that is present in every cell of the human body, in addition to being in almost all the foods in our diet; It is essential as it makes up blood cells, which is why the haemoglobin proteins it produces are so important.

Different types of iron in food

Food has two types of iron: heme iron and non-heme iron. The heme iron is found in meat, fish and poultry, and is the form of iron that is more readily absorbed in the stomach and is collected in the body after eating.

The non - heme iron found in plant foods and meat also sometimes. Foods with non-heme iron are still good to eat, but the iron in these foods is not fully absorbed like heme iron. By eating you can absorb up to 30 percent of heme iron, which is only found in animal tissues (meat, poultry, and fish). Instead, you can absorb 10.2 percent non-heme iron, which is found in plant-based foods.


Eating meat in general will increase your iron levels much more. When you eat heme iron with other non-heme iron sources, the absorption of the iron is more complete. Foods rich in vitamin C, such as tomatoes, citrus fruits, and red, yellow, and orange bell peppers can also help with the absorption of non-heme iron.
