Iron is an essential mineral that is necessary for the proper functioning of the human body. It is involved in a variety of processes, including the transportation of oxygen in the blood, the production of collagen and other proteins, and the regulation of cell growth and differentiation. While the body needs iron to function properly, it is also possible to consume too much iron, which can lead to negative health effects.
Iron is a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. It is also involved in a number of other important processes in the body, including the production of collagen, the synthesis of hormones and neurotransmitters, and the immune system.
There are two types of iron: heme iron and non-heme iron. Heme iron is found in animal-based foods like meat, poultry, and fish, and is easily absorbed by the body. Non-heme iron is found in plant-based foods and is not as easily absorbed. However, the absorption of non-heme iron can be improved by eating these foods with a source of vitamin C, such as a citrus fruit or tomato.
Iron in Meat, Poultry, and Fish
Meat, poultry, and fish are some of the most commonly consumed sources of iron. These foods are considered to be "heme" iron sources, which means that the iron they contain is easily absorbed by the body.
Red meat, such as beef, pork, and lamb, is an excellent source of iron. It is also a good source of protein, B vitamins, and zinc. Three ounces of cooked beef contains about 2.5 milligrams of iron, which is about 28% of the daily value (DV) for iron. In addition to being a good source of iron, red meat is also a rich source of heme iron, which is a type of iron that is more easily absorbed by the body. However, it is important to consume red meat in moderation as it is also high in saturated fat, which can increase the risk of heart disease if consumed in excess.
Poultry, such as chicken and turkey, is a good source of iron. Three ounces of cooked chicken contains about 1 milligram of iron, or about 11% of the daily value (DV) for iron. Poultry is also a good source of protein, B vitamins, and other nutrients. In addition to being a good source of iron, poultry is also a lean protein source, making it a healthy choice for those looking to reduce their intake of saturated fat. Poultry can be prepared in a variety of ways, including grilling, roasting, or baking, making it a versatile and convenient choice for meals. It is important to consume poultry in moderation as part of a balanced diet.
Fish, particularly fatty fish like salmon, mackerel, and sardines, is a good source of iron. Three ounces of cooked salmon contains about 1.8 milligrams of iron, or about 20% of the daily value (DV) for iron. Fish is also a good source of protein, omega-3 fatty acids, and other nutrients. In addition to being a good source of iron, fish is also a lean protein source, making it a healthy choice for those looking to reduce their intake of saturated fat. Fish can be prepared in a variety of ways, including grilling, baking, or frying, making it a versatile and convenient choice for meals. It is important to consume fish in moderation as part of a balanced diet.
Iron in Legumes and Beans
Legumes and beans are a good source of iron, as well as other nutrients like protein, fiber, and B vitamins. Legumes and beans are rich in a type of iron called non-heme iron, which is not as easily absorbed as heme iron, which is found in animal-based foods like meat, poultry, and fish. However, the absorption of non-heme iron can be improved by eating these foods with a source of vitamin C, such as a citrus fruit or tomato.
Here are some examples of legumes and beans that are high in iron:
-
Soybeans: A 1-cup serving of cooked soybeans contains approximately 8.8 mg of iron.

It is important to note that these are just a few examples of legumes and beans that are high in iron. There are many other options available, and it is a good idea to include a variety of legumes and beans in your diet to ensure that you are getting a range of nutrients. It is also important to consider other factors, such as calorie and nutrient content, when choosing legumes and beans. Legumes and beans can be consumed on their own or used as an ingredient in soups, stews, and other dishes. They can also be ground into flour and used to make bread, pasta, and other products.
