Why is iron important and how to get more of it
Iron is a mineral that plays a key role in our bodies. Without it, we wouldn't be able to efficiently transport oxygen to our cells, which would lead to a range of health issues. Despite this, many people underestimate the importance of sufficient iron intake, which can have serious consequences. What if you're suffering from an iron deficiency without even realizing it?
What is iron and why is it so important?
Iron is an essential mineral that our body needs to produce hemoglobin – a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Iron is also crucial for the proper functioning of many enzymes involved in energy metabolism and DNA synthesis.
Without an adequate amount of iron, the body cannot produce enough hemoglobin, leading to anemia. Anemia can have various causes, but iron deficiency is one of the most common. Symptoms of iron deficiency can be subtle and are often attributed to other issues, which can lead to underestimating this condition.

How to recognize iron deficiency?
Iron deficiency can manifest in various ways, with symptoms depending on the severity of the deficiency. The most common symptoms include fatigue and weakness, as the body doesn't have enough oxygen to supply muscles and tissues, leading to feelings of exhaustion. Pallor is another symptom because the lack of hemoglobin causes a loss of healthy skin color. A rapid heartbeat occurs when the heart has to work harder to provide enough oxygen, which can lead to palpitations or an irregular heartbeat. Dizziness and headaches appear due to insufficient oxygen supply to the brain. Reduced immunity is another risk, as iron deficiency makes it harder for the body to fight infections.
Iron deficiency can also cause concentration problems, as the brain needs enough oxygen to function optimally.

Who is at risk of iron deficiency?
Several groups of people are particularly at risk of iron deficiency.
Women of childbearing age often experience iron loss due to menstrual bleeding, and the need for iron increases during pregnancy and breastfeeding. Children and teenagers undergoing rapid growth need more iron, and if they don't consume enough iron-rich foods, they may be at risk of deficiency. Vegetarians and vegans need to be cautious, as iron from plant sources is less absorbable than iron from meat, and they should ensure sufficient intake or consider supplements. People with chronic illnesses such as celiac disease, Crohn's disease, or cancer may have reduced ability to absorb iron or increased need for this mineral. The elderly are also at risk, as the body's ability to absorb iron decreases with age, potentially leading to deficiency.
Iron in food
There are many ways to increase iron intake and prevent its deficiency.
It's essential to consume iron-rich foods such as red meat, liver, poultry, fish, legumes, tofu, spinach, other leafy greens, nuts, and seeds. To improve iron absorption, it's beneficial to combine iron-rich foods with those containing vitamin C, such as citrus fruits, peppers, or broccoli. Conversely, some foods and beverages, like coffee, tea, milk, or calcium-rich foods, can block iron absorption if consumed simultaneously with iron.
If you're having trouble getting enough iron from your diet, it may be worth considering supplements. However, always consult a doctor before taking supplements, as excessive iron intake can be toxic and cause health problems.
Risks associated with excess iron
While iron deficiency is a common issue, too much iron can also be dangerous. Hemochromatosis, a genetic disorder causing excessive iron storage in the body, can lead to organ damage, such as in the liver, heart, or pancreas. Symptoms of iron excess may include fatigue, abdominal pain, weakness, and in severe cases, heart problems. Therefore, it's important to monitor iron levels in the body and not exceed the recommended daily intake.
When to seek medical advice?
If you suspect an iron deficiency, it's important to seek medical help. A doctor can perform blood tests to determine iron levels and other indicators such as ferritin (the storage form of iron in the body) and hemoglobin. Based on test results, your doctor may recommend dietary changes or prescribe iron supplements.
Have you ever wondered if your fatigue, concentration problems, or paleness might be related to an iron deficiency? This mineral is essential for our body, and its deficiency can have serious consequences. Don't ignore the symptoms and ensure you supply your body with enough iron.
Iron deficiency is a common but often underestimated problem that can have serious health consequences. The key to prevention and treatment is early diagnosis and the right nutritional approach. If you suspect you might suffer from an iron deficiency, don't hesitate to seek professional help. With proper care and dietary adjustments, you can prevent iron deficiency from negatively affecting your life.
