If you've been feeling tired more often lately, dizzy or even notice that your skin is a little paler than usual, you may just be suffering from iron deficiency. In fact, iron is an essential mineral for your body, but it is often a bit overlooked. Today we dive into the question: how important is iron really for your body?
What does iron actually do?
Iron plays a crucial role in your body. It is a key component of hemoglobin, the protein in your red blood cells that transports oxygen from your lungs to the rest of your body. Without enough iron, your body simply doesn't get enough oxygen, and that can lead to fatigue, weakness, and even difficulty concentrating.
But that's not all! Iron is also important for your immune system and for your cells that make energy. It supports the functioning of various enzymes that ensure healthy metabolism and helps in the production of new cells. In short, without iron, your body is unable to function optimally.
What are the symptoms of iron deficiency?
Many people think you only need iron if you are anemic, but even a milder deficiency can affect your health. Symptoms are often vague and are sometimes confused with other symptoms. These include:
- Fatigue and lethargy.: You have trouble mustering energy, even for daily tasks.
- Pale skin: Because you have fewer red blood cells, your skin may look dull or pale.
- Dizziness and shortness of breath.: When your blood can carry less oxygen to your organs, you feel out of breath faster.
- Cold hands and feet.: Your blood vessels are less able to carry oxygen to your extremities.
How do you get enough iron?
Fortunately, you can easily maintain your iron levels by eating the right foods. There are two types of iron: heme iron (from animal products) and non-heme iron (from plant sources). Heme iron is more easily absorbed by your body, but non-heme iron can also provide good intake if you combine it with the right nutrients.
Animal sources of iron:
- Red meat (such as steak or lamb).
- Poultry (chicken, turkey)
- Fish (tuna, sardines)
- Eggs
Plant sources of iron:
- Green leafy vegetables (spinach, kale)
- Lentils, chickpeas and beans
- Quinoa and oatmeal
- Dried fruits such as apricots and raisins
A helpful tip: vitamin C helps improve iron absorption. So add a little lemon to your salad or drink a glass of fresh orange juice with your meal!
What if you are deficient?
If you find that you have symptoms of iron deficiency, it is important not to ignore it. In many cases, supplementing your diet with iron-rich foods can already help. In more severe cases, you may need to take supplements. Always consult a doctor before starting to take iron supplements, as too much iron can also be harmful.
How important is iron to your body?
Iron is an undeniably important mineral for your body. It is responsible for oxygen transport in your blood and supports numerous other vital functions. Make sure you get enough iron through a varied diet with both animal and plant sources of iron. And if you are still in doubt about whether you have enough iron, it is always a good idea to visit your doctor for a check-up.
