Iron is a key trace element for the human body. It plays an indispensable role in hematopoietic functions. It is used in the synthesis of hemoglobin - the main structural protein of erythrocytes, ensuring the transfer of oxygen to cells and carbon dioxide to the lungs. Persistent iron deficiency is associated with impaired hematopoietic function and the development of iron deficiency anemia .
Iron deficiency occurs in three cases - with difficulty in absorbing iron in the intestinal tract, with accelerated loss of the trace element and especially with reduced intake. This essential trace element must enter the body regularly and this can be done by eating foods rich in iron .
In case of iron deficiency - iron nutritional regime
Iron deficiency is the leading nutritional deficiency in the world . Both children and adults experience serious problems with its daily supply in sufficient doses. This requires knowing the most iron-rich foods and making them a major part of the diet of those affected.
Both animal and plant products can be used as a source of iron. However, iron contained in foods of animal origin is easier to digest and more important for humans.
The most powerful sources of iron among animal foods include:
- Tender beef;
- The turkey;
- The chicken;
- Fish;
Among plant foods, which can also provide high doses of iron, stand out:
- Legumes;
- Leafy vegetables - spinach, nettle, celery;
- Whole grain products;
To ensure optimal absorption of iron, it is necessary to combine the intake of iron-rich foods with increased intake of vitamin C. It has been shown that it facilitates the transport of the chemical element from the intestinal tract to the blood.
Improving the diet is a key step to permanently compensate for iron deficiency . It would be good for these foods rich in iron to be taken regularly by everyone, because iron deficiency often does not provoke clear symptoms until iron deficiency anemia occurs. Thus, a rational diet is an effective means of preventing the risk of complications.
