Once you realize where the elements around us come from, even everyday life takes on a touch of magic. A fascinating example is natural iron, one of the most important metals on Earth. It\u2019s not actually a product of Earth, but comes directly from outer space. And that\u2019s not nearly all you should know about this valuable element! <\/p>\n

From star to supernova: How is natural iron formed?<\/h2>\n

The temperatures inside large stars are so high and the pressure so gigantic that the atoms fuse together. First hydrogen becomes helium, then carbon, oxygen and so on. Gradually, the most diverse elements are formed, from the lightest to the heaviest. <\/p>\n

The end point of this process is iron. If the star produces even heavier elements, this costs energy instead of releasing it. As a result, the star eventually collapses and becomes a supernova. In the subsequent explosion, huge quantities of iron are released and hurled into space together with other elements. <\/p>\n

At some point, all these particles are deposited in clouds of gas and dust, from which new stars, planets and moons are later formed, including our Earth. So the natural iron from our planet originally comes from distant stars. Fascinating! <\/p>\n

Natural iron on earth<\/h2>\n

Iron is one of the most common elements on earth. In fact, it is the most abundant of all metals. Iron is found in the earth’s core, in stones, sand and water<\/strong>. And many soils, plants and animals<\/strong> also contain iron. Iron pervades our entire planet and we encounter it in many different forms, from reddish layers of rock to iron-rich mineral springs and even our own blood. <\/p>\n

Iron is also<\/strong> indispensable in the human body<\/strong>, for example for the formation of red blood cells and as a key component of the red blood pigment haemoglobin. Iron contributes to the normal function of the immune system and normal energy metabolism, plays a role in cell division and has many other functions in the human body. <\/p>\n

Iron in food – the power of nature<\/h3>\n

Many different foods<\/a> have a high iron content, but it is not always easy to absorb iron from food – especially if you have an unbalanced diet. Animal iron has a particularly high bioavailability in the form of so-called heme iron. However, plant-based iron (so-called non-heme iron) is also an important source for the body. Tip: Vitamin C can increase the absorption of iron<\/a>. It is therefore worthwhile always consuming a little lemon juice or fresh fruit or vegetables containing vitamin C together with iron-rich foods. <\/p>\n

But which foods contain the most iron? These foods, for example, are very rich in iron: <\/p>\n
