Iron is responsible for transporting oxygen from your lungs to the cells and muscles in your body, and deficiency can cause you to experience low energy levels, shortness of breath, chest pain, and more.
It can also cause you to crave weird things, like ice and dirt.
We get iron from the foods we eat, but our bodies don’t retain every bit of iron we consume — and we naturally shed it every day through normal bodily functions. So if you’re not getting enough in your diet or in supplements, you could develop a deficiency called anemia.
That’s why it’s essential to include foods high in iron in your diet. Some of the best sources of iron include red meat, seafood, and leafy green veggies.
Most people need around 18 mg of iron per day. However, pregnant women need approximately 27 mg of iron per day, and lactating women need about 9 mg of iron daily. If you’re at risk for iron deficiency, you may need to consume more than the recommended amount.
Types of Iron
There are two types of iron: heme and non-heme. Heme is a Greek word meaning blood, so it makes sense that heme iron is found in animal products, while non-heme iron is found in plant-based foods.
Heme iron is the most absorbable form of iron. That’s likely why research shows that people who regularly eat animal meats and seafood are less likely to develop iron deficiency.
The amount of heme iron absorbed by the body depends on a few factors, including the amount of iron in the food and how much was eaten at one time. Generally, the body absorbs around 15 percent of the heme iron that you consume.
Keep in mind that iron absorption is affected by various other factors, including the type of food and how it was cooked. For instance, some nutrients like vitamin C improve iron absorption while others inhibit it (such as phytates).
Non-heme iron is the type of iron that is found in plant products. It is not as absorbable as heme iron, but it is still an essential source of iron for the body. Some of the best sources of non-heme iron include leafy green vegetables, nuts, and legumes.
The body absorbs up to 12 percent of the non-heme iron you eat. This means that it is vital to include a variety of iron-rich foods in your diet to get the most benefit. Some of the best sources of non-heme iron include leafy green vegetables, nuts, and legumes.
Foods High in Iron
According to the USDA, a 3-ounce serving of red meat contains around 2.7 milligrams of iron. This means that it is a good source of iron, providing around 20% of the recommended daily intake.
Some red meats high in iron include beef, pork, lamb, and goat.
Organ meats, such as liver, kidney, and heart, are one of the greatest sources of iron, even though it can be an acquired taste (to put it gently). For example, a 3-ounce portion of Goose liver packs a whopping 30.5 mg of iron —more than you need for the whole day.

The color of the turkey affects its iron content.
A 3-ounce serving of dark turkey contains around 1.3 mg of iron, while white meat turkey only has about 0.7 mg for the same amount. This makes dark turkey a good source of iron and other essential nutrients like protein.
