We often associate iron with the risk of not having enough of it. When you visit your doctor complaining of fatigue, lethargy, or weakness, they may routinely check your iron levels to ensure you have an adequate supply of this essential mineral. The reason for this is that insufficient regular intake of iron can lead to a reduction in the size of your red blood cells, impairing their ability to transport the usual amount of oxygen from your lungs to other parts of your body. This condition could potentially lead to iron-deficiency anemia, resulting in fatigue and overall bodily weakness. Fortunately, there are numerous high-iron foods you can incorporate into your diet to help address this concern.
The Advantages of Incorporating Iron-rich Foods into Your Diet Include
As stated by the National Institutes of Health (NIH), iron plays a pivotal role in the production of myoglobin, which supplies oxygen to your muscles, and hemoglobin, which transports oxygen from your lungs to all parts of your body. To enjoy these advantages and safeguard yourself from iron deficiency, you can incorporate iron-rich foods into your daily dietary regimen.
There are two primary types of iron found in food: heme iron and non-heme iron. Heme iron is present in animal products, while non-heme iron is found in plant-based foods. While both types offer benefits, it's worth noting that the body absorbs heme iron more efficiently than non-heme iron, as stated by the NIH.
What Is the Recommended Daily Iron Intake?
The daily recommended iron intake, expressed as the Daily Value (DV), primarily varies based on your age group, gender, and dietary habits. For women aged 19-50, the DV is 18 milligrams, whereas for men in the same age range, it is 8 grams. However, as previously mentioned, non-heme iron from plant-based sources is not absorbed as efficiently as heme iron, which implies that vegetarians and vegans may require a higher dietary iron intake compared to others.
Top Iron-Rich Foods
The subsequent iron-rich foods are categorized as either "excellent" or "good" sources of iron. The FDA designates an "excellent source" of iron as a food providing over 20% of your daily value, while a "good source" contains between 10-19% DV.
