Nutrition: 7 Healthy Foods That Are Very High in Iron

Even in a country as well fed as ours, it can be hard to get all the nutrients your body needs. Iron, which your red blood cells require to transport oxygen from your lungs to the rest of your body, is one of those sometimes elusive nutrients. That’s especially true for women thanks, monthly blood loss! and for vegetarians, since meat is one of the best sources of iron. About one in five women of childbearing age has iron-deficiency anemia, a condition when the body doesn’t have enough iron, according to the National Institutes of Health, and there are more than 3 million cases total in the U.S. It can lead to an array of health problems including dizziness, fatigue, shortness of breath, chest pain, and more.

When it comes to the iron we get from food, there are two different kinds: heme, or animal-based iron, and non-heme, or plant-based iron. Zelman explains that heme iron is more easy for our bodies to absorb. So even if you’re eating a lot of iron-packed plant sources, you still might not be getting everything you need.

The Bottom Line

Iron is an important mineral that must be consumed regularly as your body cannot produce it on its own.

Yet it should be noted that some people need to limit their intake of red meat and other foods high in heme iron.

However, most people are easily able to regulate the amount they absorb from food.

Remember that if you don’t eat meat or fish, you can boost absorption by including a source of vitamin C when eating plant sources of iron.
