Have you ever been told that you are anemic? While anemia comes in many forms, iron-deficient anemia is one of the most widespread forms. It affects toddlers, children, adolescents, and adults of all ages and can come with a cost!
Iron is needed by all living organisms, it's especially crucial for human health as it helps carry oxygen to all of our cells!
There are various food sources of Iron: Red Meat🥩, Nuts and Seeds🥜, Leafy Green Vegetables🥬🥦, and Legumes.
It is important to know that iron from plant sources is known as Non-Heme Iron and is in a different form than iron from animal sources, Heme Iron. Heme (Fe2+) iron is more bioavailable as it does not need to undergo hydrolysis compared to its counterpart, Non-Heme (Fe3+), to be absorbed by the small intestine.
❤️Iron-deficient anemia occurs when there is a problem getting enough iron, whether it be with absorption issues or with lack of consumption. Anemia comes on slowly to start but can become a serious concern, with dizziness, weakness, and fatigue.
🦴Iron is stored in the bones, liver, spleen, red blood cells, and a few other locations. This is why it takes some time to become fully anemic, as you have to use up all of your iron stores, including from the bones.
🛑Conversely, iron can also exist in excess in our bodies, primarily due to a genetic condition known as hemochromatosis. This condition results in the body being unable to gauge iron levels. Hemochromatosis is treated with regular blood removal throughout a patient's lifetime to keep serum levels less than 30 micrograms/liter.
The recommended dietary allowance for Iron is:
👉Men: 8mg/day
Women:
👉Postmenopause: 18 mg/day
👉Premenopause: 8 mg/day
👉Pregnancy: 27 mg/day
👉Lactation: 9 mg/day
🛑NOT TO EXCEED: 35 mg/day (tolerable upper limit)
