„Gesundes, nahrhaftes Essen ist die einfache und richtige Lösung, um mühelos überschüssiges Körpergewicht loszuwerden und für immer schlank und gesund zu werden.“- Subodh Gupta, Autor von 7 Habits of Skinny Woman
Der berühmte Autor weiß genau, wovon er spricht. Ernährung ist der Baustein unserer allgemeinen Gesundheit. Wir benötigen ausreichende Mengen an Vitaminen und Mineralstoffen, damit unsere Systeme optimal funktionieren. Aufgrund unserer hektischen Zeitpläne sind wir möglicherweise nicht in der Lage, die ausreichenden Mengen dieser Nährstoffe zuzuführen, was zu Mängeln führt, die sich auf unsere Gesundheit auswirken. Eisen ist ein solcher Nährstoff, der für unseren Körper wichtig ist.

Eisen und unsere Gesundheit
Eisen ist ein wichtiges Mineral, das verschiedene Funktionen in unserem Körper erfüllt. Das wichtigste davon ist die Produktion roter Blutkörperchen, die Sauerstoff im Körper transportieren. Es ermöglicht unseren Muskeln auch, Sauerstoff zu speichern und zu verwenden
Eisen ist Teil vieler Enzyme und hilft daher bei der Ausführung vieler Zellfunktionen. Enzyme erleichtern die Verdauung von Lebensmitteln und andere wichtige Reaktionen, die in unserem Körper auftreten
Eisen ist daher wichtig für Ihren Körper und Sie sollten die unten angegebene empfohlene Dosierung aus Ihrer täglichen Ernährung erhalten.

Iron deficiency is also known as anaemia or iron deficiency anaemia. This condition is one of the most common nutritional deficiencies, particularly in children and pre-menopausal women. This condition is characterized by the depletion of the body’s stores of iron and inability of the body to maintain normal levels of haemoglobin in the blood.
Haemoglobin is a substance that is present in red blood cells that enable them to carry oxygen throughout the body. Lack of sufficient iron makes the body unable to produce enough haemoglobin. This results in functional and health impairment which adversely affects the functioning of several organ systems.
Causes of Iron Deficiency
The causes revolve around insufficient consumption of iron or losing too much iron. In both the cases, your body is unable to produce enough haemoglobin. Some of the most common iron deficiency causes are as follows.
1. Increased Iron Needs:
There are certain conditions under which people need additional amounts of iron
2. Loss of Blood:
When people lose blood, they also lose iron as blood contains iron within the red blood cells. So they need extra iron to replace the lost iron.
3. Lack of Iron in Diet:
The iron needed by our bodies is mostly obtained from the foods that we eat. Consumption of too low a dose of iron over time can lead to iron deficiency. Iron-rich foods include meat, leafy vegetables, eggs and iron-fortified foods. Infants and children also need iron from their diet for their proper growth and development.
4. Mal-absorption of Iron:
Besides consumption, iron from food should be absorbed into your bloodstream in your small intestine. Celiac disease is an intestinal disorder that affects your intestine’s ability to absorb nutrients from digested food, thus causing iron deficiency. Absorption of iron is also affected if part of your intestine has been bypassed or removed surgically. The amount of iron absorbed from foods depends upon other factors given below.
Iron from animal sources like meat, chicken and fish is heme iron which can be absorbed 2 to 3 times more efficiently than non-heme iron from plants.
Absorption of non-heme iron from plant foods depends upon the other types of foods eaten with them. For instance, foods like meat, chicken and fish which contain heme iron increase absorption from foods containing non-heme iron such as fortified cereals, spinach and certain beans. Foods containing vitamin C can also enhance the absorption of non-heme iron when eaten at the same meal.
Substances like polyphenols, phytates or calcium which are found in some foods or drinks such as tea, coffee, whole grains, legumes, milk and dairy products can decrease the absorption of non-heme iron.
Victims of Iron Deficiency
Though anyone can suffer from iron deficiency, certain people are at greater risk. Since the risk is high their needs for iron is greater than others.
Women lose blood during menstruation and so they are at a greater risk of suffering from anaemia. Pregnant women can also get this deficiency because of high iron requirement.
2. Infants and Children:
Infants, particularly those with low birth-weight or born prematurely, do not get enough iron from breast milk or formula and so they are at a higher risk of iron deficiency. Children need extra iron during growth phase. Children with special health needs such as those with chronic infections or restricted diet are also at risk.
Those who do not eat meat are at a higher risk of iron deficiency. As stated earlier, plants contain non-heme iron which needs to be supplemented with other sources of heme iron like meat, fish and eggs to facilitate their absorption.
4. Frequent Blood Donors:
Those who donate blood frequently are at an increased risk of iron deficiency as their iron stores get depleted due to blood donation. Low haemoglobin caused by blood donation is, however, a temporary problem which can be cured by eating iron rich foods.
Iron Deficiency Symptoms
Inadequate levels of iron can impair body functions. Most physical signs and symptoms do not show up as they are mild. You can notice them only when your anaemia gets worse. The symptoms are not visible during the early stages of iron deficiency. A person having iron deficiency may have the following symptoms.

Iron Deficiency Diseases
Iron deficiency is a serious condition which, if taken lightly, can lead to long term health issues. Mild deficiency of iron causes no severe complications, but when left untreated, it can lead to the following health issues.
Severe deficiency of iron can cause anaemia due to the disruption of the normal lifespan of a red blood cell. In this condition, haemoglobin levels are so low that the blood is unable to enough oxygen to the cells, thus affecting the entire body. Symptoms of anaemia include looking very pale, breathlessness, dizziness and fatigue. It also results in reduced immune function and impaired growth and cognition.
2. Heart Ailments:
Deficiency of iron can lead to rapid or irregular heartbeat. When you are anaemic, your heart is required to pump more blood to compensate for the lack of oxygen carried in your blood. This can cause enlarged heart or heart failure.
3. Inadequate Growth:
Severe deficiency of iron can lead to delayed growth and development in infants and children. It is also associated with increased susceptibility to develop infections.
4. Complications in Pregnancy:
Pregnant women are at a higher risk of iron deficiency. It can lead to premature births and babies with low birth-weight. This condition can be easily prevented during pregnancy by taking iron supplements as part of prenatal care.
5. Colon Cancer:
Iron deficiency is one of the causes of colon cancer. A research conducted on 628, 882 patients of 40 years of age and above indicated that 3.1% or 19, 349 patients had iron deficiency anaemia. Thus, those suffering from iron deficiency are at a greater risk of developing colon cancer.
Iron deficiency can result in fatigue. It is characterized by depression and lack of sleep. Hence, iron deficiency should be recognized and treated to prevent fatigue.

Treatment of Iron Deficiency
Iron deficiency should not be ignored as it can lead to several health problems. Proper diagnosis and treatment of this problem is important before the condition worsens. Iron deficiency can be easily diagnosed by taking a haemoglobin test which measures haemoglobin or haematocrit test which measures the percentage of red blood cells in your blood by volume.
Reduction in haemoglobin and haematocrit levels indicates a serious deficiency of iron. Treatment of iron deficiency depends upon other factors such as your age, health and cause of iron deficiency. Some of the ways of treating iron deficiency are given below.
1. Consumption of Iron Rich Foods:
Mild deficiency of iron can be cured by including iron rich foods in your diet. The iron from animal sources like meat, poultry and eggs is more easily absorbed by your body. If you are a vegetarian, you need to increase your intake of iron-rich plant-based foods to absorb the same amount of iron as the plant sources. The list given below shows the sources of heme and non-heme iron.
