What is iron and what is it used for?

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.
A.

What foods are rich in iron?

Some of the best plant sources of iron are:
  • Beans and lentils.
  • Tofu.
  • Baked potatoes.
  • Cashews.
  • Dark green leafy vegetables such as spinach.
  • Fortified breakfast cereals.
  • Whole-grain and enriched breads.
  • What not to eat when you have anemia?

    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.
    • Liver.
    • Seafood.
    • Fortified foods.
    • Beans.
    • Nuts and seeds.
  • What is iron good for?

    Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. Hemoglobin represents about two-thirds of the body's iron. If you don't have enough iron, your body can't make enough healthy oxygen-carrying red blood cells.
  • What cereal is high in iron?

    Fortified Breakfast Cereals. Breakfast cereals are often a main source of iron, but you have to choose the right types. The key is to look for a fortified cereal that contains 100 percent of your daily value of iron. A one-cup serving of cereal contains 18mg of iron.
B.

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.
  • Can magnets attract the iron in your blood?

    The iron in hemoglobin is not ferromagnetic. Ferrohemoglobin (without oxygen attached) is weakly paramagnetic (is attracted to an external magnetic field). So it can align with a strong external magnetic field, but this effect is generally very weak.
  • How much iron is in the human body?

    Males of average height have about 4 grams of iron in their body, females about 3.5 grams; children will usually have 3 grams or less. These 3-4 grams are distributed throughout the body in hemoglobin, tissues, muscles, bone marrow, blood proteins, enzymes, ferritin, hemosiderin, and transport in plasma.
  • Is it better to take calcium at night?

    You need to take calcium carbonate with food, because it's easier for your body to absorb that way. You can take calcium citrate on an empty stomach or with food. To maximize your absorption of calcium, take no more than 500 mg at a time. You might take one 500 mg supplement in the morning and another at night.
C.

What are some interesting facts about iron?

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.
  • Where do you find iron on earth?

    Iron is the fourth most abundant element, by mass, in the Earth's crust. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite.
  • How did the iron get its name?

    Origin of name: from the Anglo-Saxon word "iron" or "iren" (the origin of the symbol Fe comes from the Latin word "ferrum" meaning "iron"). Possibly the word iron is derived from earlier words meaning "holy metal" because it was used to make the swords used in the Crusades..
  • Where do you find iron ore?

    Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S., Eastern Canada and Northern Sweden. Magnetite bearing banded iron formation is currently mined extensively in Brazil, which exports significant quantities to Asia, and there is a nascent and large magnetite iron-ore industry in Australia.
