Iron is an essential mineral that helps prevent anaemia and protects the body from infection. It is a component of haemoglobin, which carries oxygen through the body. While the body can store iron, it cannot produce it, and a prolonged deficiency will result in anaemia. Iron-rich foods include meat, eggs, and seafood, as well as plant-based sources such as legumes, nuts, seeds, and green vegetables.

What You'll Learn
Meat and eggs are good sources of iron
Eggs are another good source of iron, especially for those who do not eat meat. While the iron content of eggs may be lower than that of meat, they still provide a significant amount of this essential mineral. Including eggs in your diet can help ensure you are getting enough iron, especially when combined with other iron-rich foods.
It is important to note that some people may need to limit their intake of red meat and other foods high in heme iron, such as liver. However, for most people, meat and eggs can be part of a healthy and balanced diet that provides sufficient iron intake.
In addition to meat and eggs, there are other food sources that can help boost your iron intake. These include legumes, such as beans, lentils, chickpeas, and soybeans, which are particularly good sources of iron for vegetarians. Including foods rich in vitamin C, like citrus fruits, tomatoes, and peppers, can also enhance the absorption of iron from plant-based sources.

Seafood and poultry contain heme iron
Iron is a mineral that serves important functions in the body, but many people don't get enough. Iron is an essential mineral that is a part of haemoglobin, which helps maintain strength and energy. Seafood and poultry contain heme iron, which is the type of iron that comes from animal proteins in our diet. Heme iron is found in meat, poultry, seafood, and fish. It is derived from hemoglobin, which is only found in animal foods that originally contained it, such as red meats, fish, and poultry.
Heme iron is more easily absorbed by the body than non-heme iron, which is found in plant-based foods. This is why those who don't eat meat may be at a higher risk of iron deficiency. Heme iron comprises 40-45% of the iron in meat, while the rest is non-heme iron. The body absorbs up to 30% of heme iron consumed, while only 2-10% of non-heme iron is absorbed.
Meat, in general, boosts iron levels more effectively than non-heme iron sources. For example, one serving of ground beef provides 15% of the daily value (DV) for iron and is a readily accessible source of heme iron. Seafood, such as tuna, haddock, mackerel, and sardines, are also good sources of heme iron. A serving of canned tuna can provide about 8% of the DV for iron.
To enhance the absorption of heme iron, it can be paired with foods containing non-heme iron, such as fruits and vegetables. Additionally, foods rich in vitamin C, like citrus fruits, tomatoes, and peppers, can aid in the absorption of both heme and non-heme iron.

Vegetarians can eat legumes, nuts, seeds
For vegetarians, it is important to know which plant-based foods are good sources of iron. Iron is an essential mineral that plays an important role in many bodily functions, and many people do not get enough of it.
Legumes, such as beans and lentils, are excellent sources of iron for vegetarians. For example, a half-cup of cooked black beans provides around 1.8 milligrams of iron, or 10% of the DV. Legumes are also a good source of folate, magnesium, potassium, and fibre. To maximise iron absorption, it is recommended to consume legumes with vitamin C-rich foods, such as tomatoes, greens, or citrus fruits.
Nuts and seeds are also good options for vegetarians to increase their iron intake. Pumpkin seeds, for instance, are a tasty and portable snack that provides 2.5 mg of iron per ounce, which is 14% of the DV. They are also a good source of vitamin K, zinc, and manganese, and are among the best sources of magnesium. Other nuts and seeds that can add iron to your diet include dark chocolate, which has significant antioxidant activity, and quinoa, a gluten-free grain that provides 2.8 mg of iron per cooked cup.
In addition to legumes, nuts, and seeds, vegetarians can also include vegetables such as spinach, potatoes, and sweet potatoes in their diet to boost iron intake. It is worth noting that tomatoes contain more iron when dried or concentrated, and potatoes have higher iron content when unpeeled.

Iron-fortified foods include tofu, grains, bread
Iron is an essential mineral with several important functions, including carrying oxygen throughout your body as part of red blood cells. A deficiency in iron can cause anemia and lead to symptoms like fatigue. Menstruating women and those who don't consume meat are at a particularly high risk of deficiency.
There are two types of iron: heme and non-heme. Heme iron is found in meat, fish, and poultry, and it is the form of iron that is most easily absorbed by the body. Eating meat generally boosts your iron levels far more than eating non-heme iron. However, some people may need to limit their intake of red meat and other foods high in heme iron.
Non-heme iron is found in plant-based foods such as fruits, vegetables, nuts, and grains. While the iron in these foods is not absorbed as efficiently, they are still an important part of a nutritious, well-balanced diet. Eating heme iron with foods higher in non-heme iron can improve overall absorption. Additionally, consuming vitamin C with plant sources of iron can boost absorption.
Iron-fortified foods include tofu, grains, and bread. Tofu is a soy-based food that is popular among vegetarians and in some Asian countries. A half-cup (126-gram) serving provides 3.4 mg of iron, or 19% of the Daily Value (DV). Tofu is also a good source of thiamine, calcium, magnesium, selenium, and protein. Bread, especially fortified varieties, can also be a good source of iron.

Vitamin C aids absorption of iron
Iron is an essential mineral that is a part of hemoglobin, which helps maintain strength and energy. It is also a component of myoglobin, an oxygen storage protein found in muscles. The human body cannot produce iron on its own, so it must be consumed regularly.
Iron deficiency is very common, and those at risk include children, adolescents, women of reproductive age, pregnant women, vegetarians, and vegans. Iron is absorbed into the bloodstream in the small intestine, and an intestinal disorder, such as celiac disease, can affect the body's ability to absorb nutrients from food, leading to iron deficiency anemia.
Foods high in vitamin C include citrus fruits, dark green leafy vegetables, bell peppers, melons, and strawberries. Hence, drinking citrus juice or consuming vitamin C-rich foods alongside iron-rich foods can increase iron absorption. This is especially beneficial for vegetarians and vegans, as plant-based sources of iron may be less easily absorbed by the body.
In summary, vitamin C plays a crucial role in enhancing the absorption of iron, particularly non-heme iron, and can be obtained from various fruits and vegetables, making it an important component of a balanced diet.
