What is Iron

Iron (atomic symbol Fe) is most commonly known and used as a metal. It is also a trace mineral that is essential to humans. You will find it in every cell in your body. There are two forms of iron for dietary purposes:

Heme - This is mainly found in animal products and is an organic molecule that is tightly bound to a protein. It is much easier for the body to absorb.

Non-Heme - Is found mainly in plant foods and is more difficult for the body to absorb.

Benefits of Iron

Iron functions in the hemoglobin, which is a molecule of the red blood cell that carries oxygen to different tissues throughout our body. It also functions in myoglobin, which is a molecule that carries oxygen to our muscles. Iron is also used for medical purposes to increase the body's red blood cells.

Iron deficiency may result in internal bleeding, anemia, fatigue, and depression. Toxicity issues with iron could result in heart disease, vomiting, nausea, or infections.

Iron Foods

Good sources or iron are red meat, sesame seeds, sunflower seeds, pumpkin seeds, raisins, spinach, and kidney beans, garbanzo beans, navy beans, and broccoli. It is recommended for children and women to consume 10-20 mg per day. For men 8-10 mg per day is sufficient. Pregnant and nursing women need significantly more and it is best for them to consult with a healthcare provider for recommended amounts.
