10 Surprising Facts About Iron You Need to Know
Iron is an essential mineral that plays a critical role in the human body. It is responsible for carrying oxygen throughout the body, regulating cell growth and division, and strengthening the immune system. Our bodies need iron to function correctly, and a deficiency in this mineral can lead to a range of health problems. But did you know these 10 surprising facts about iron?
Fact #1: Iron is the Most Common Element on Earth
Iron is the fourth most abundant element in the Earth’s crust, making up around 5% of the planet’s total weight. It is also the most commonly used metal worldwide, with applications in construction, transportation, energy production, and many other industries.
Fact #2: Iron Was Used for Decoration in Ancient Egypt
The ancient Egyptians were the first to use iron for decoration. They used iron to make jewelry, beads, and other ornaments. However, they could not produce iron on a large scale, and it was considered more valuable than gold.
Fact #3: The Human Body Contains Around 4 Grams of Iron
Iron is found in many parts of the human body, including the blood, liver, and muscles. The average person has around 4 grams of iron in their body, with most of it stored in the blood as a part of hemoglobin.
Fact #4: Iron Deficiency is the Most Common Nutritional Deficiency in the World
According to the World Health Organization, iron deficiency is the most common nutritional deficiency globally, affecting more than two billion people worldwide. The condition can lead to anemia, fatigue, weakness, and impaired cognitive function.
Fact #5: The Iron in Food Comes in Two Forms
The iron in food comes in two forms: heme and non-heme. Heme iron is found in animal-based foods, such as red meat, poultry, and fish, while non-heme iron is found in plant-based foods, such as beans, spinach, and tofu. Heme iron is more easily absorbed by the body than non-heme iron.
Fact #6: Iron Can Be Toxic in Large Amounts
While iron is essential for good health, too much of it can be toxic. Iron toxicity, also known as iron poisoning, occurs when there is an excessive buildup of iron in the body. Symptoms of iron toxicity include vomiting, diarrhea, fatigue, and stomach pain.
Fact #7: Iron-Rich Foods Can Help Prevent Iron Deficiency
A diet that includes iron-rich foods such as meat, fish, poultry, beans, and leafy green vegetables can help prevent iron deficiency. Vitamin C can also increase the absorption of iron from plant-based foods.
Fact #8: Women Are More Likely to Experience Iron Deficiency
Women are more likely to experience iron deficiency than men, especially during pregnancy. Iron is essential for fetal development, and pregnant women need twice as much iron as non-pregnant women.
Fact #9: Iron Absorption Can Be Hindered by Certain Foods
Iron absorption can be hindered by certain foods or substances, such as tea, coffee, and calcium. These substances can bind to iron and prevent its absorption by the body.
Fact #10: Iron Supplements Can Help Improve Iron Deficiency
Iron supplements can help improve iron deficiency in individuals who cannot consume enough iron through their diet alone. However, they should only be taken under the guidance of a healthcare professional since over-consumption of iron supplements can be toxic.
In conclusion, iron is a critical mineral in the human body that plays a range of essential functions. Iron deficiency is a common problem worldwide, but a balanced diet including iron-rich foods can help prevent it. Nevertheless, too much iron can be toxic, and iron supplements should only be taken under medical supervision. Understanding these 10 surprising facts about iron can help individuals ensure they are getting enough of this vital mineral for optimal health.
