Is the iron in your body the same as the metal?
In the metal, it's iron atoms (often combined with other metal atoms to form an alloy such as steel) in a solid matrix. In the body, iron is combined in other molecules such as hemoglobin. It's the same element, but in the body it is part of a molecule called hemoglobin. It is basically an iron porphyrin complex.
Some of the best plant sources of iron are:
- Beans and lentils.
- Baked potatoes.
- Dark green leafy vegetables such as spinach.
- Fortified breakfast cereals.
- Whole-grain and enriched breads.
- Add these foods to your diet to get more iron and help fight iron deficiency anemia:
- Leafy greens. Leafy greens, especially dark ones, are among the best sources of nonheme iron.
- Meat and poultry. All meat and poultry contain heme iron.
- Fortified foods.
- Nuts and seeds.
- Common side effects may include:
- constipation, diarrhea;
- nausea, vomiting, heartburn;
- stomach pain, upset stomach;
- black or dark-colored stools or urine;
- temporary staining of the teeth;
- headache; or.
- unusual or unpleasant taste in your mouth.
- The average daily iron intake from foods and supplements is 13.7–15.1 mg/day in children aged 2–11 years, 16.3 mg/day in children and teens aged 12–19 years, and 19.3–20.5 mg/day in men and 17.0–18.9 mg/day in women older than 19. The median dietary iron intake in pregnant women is 14.7 mg/day .
Most of it is used to make steel — an alloy of iron and carbon — which is in turn used in manufacturing and civil engineering, for instance, to make reinforced concrete. Stainless steel, which contains at least 10.5 percent chromium, is highly resistant to corrosion.
- Iron's chemical symbol, Fe, comes from "ferrum", the Latin word for iron. To this day, metals that contain iron are known as 'Ferrous' metals. Iron is the second-most abundant metal in the Earth's crust, behind only aluminum.
- Animal sources (called “heme iron”) include meat, fish and poultry. Our bodies easily absorb this type of iron. Plant sources (called “non-heme iron”) include dried beans, peas and lentils and some fruits and vegetables. In Canada, grain products like flour, pasta and breakfast cereals are fortified with iron.
- Iron is used more than any other metal for producing metal alloys. The most important iron alloys include cast iron, pig iron, wrought iron, and steel. There are various alloys of steel, but they all contain iron as the main metal. Carbon is one of the main alloying elements mixed with iron to make steel.
Iron is the sixth most common element in the universe. Iron is the fourth most abundant element in the Earth's crust by weight. It is the most abundant element in the total composition of the planet. Iron is found in both the inner and outer core of Earth.
- Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly known as rust.
- Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4).
- Iron is reactive. It reacts with most acids like sulfuric acid. It makes ferrous sulfate when reacted with sulfuric acid. Iron reacts with air and water to make rust.
