Iron is an essential mineral for the proper functioning of the human body. It is essential in the production of hemoglobin and myoglobin, proteins responsible for transporting oxygen in the body, as well as in the formation of various enzymes. This nutrient is essential for maintaining the adequate energy levels, strengthen the immune system and prevent disorders such as iron deficiency anemia.
Although the human body needs only small amounts of iron, it is not able to produce it on its own. Therefore, it is necessary to obtain it through diet. The list of iron-rich foods is wide and varied, including options of both animal and plant origin, making it possible to meet daily requirements with a balanced and diversified diet.
Why is iron important in our diet?
Iron not only plays a key role in the production of hemoglobin, but is also essential for various biological functions. These include:
- Oxygen transport: Iron is needed to produce hemoglobin, which carries oxygen from the lungs to the body's tissues.
- Brain functions: Improves memory and concentration, increasing cognitive efficiency.
- Strengthening of the immune system: Helps in the production of immune cells.
- Energy production: It participates in the synthesis of ATP, the energy molecule of cells.
An iron deficiency can cause Fatigue, pale skin, weakness, cold hands and feet, headaches and dizziness. Therefore, it is crucial for all ages, from growing children to pregnant women and older adults.
Classification of iron in foods
There are two main types of iron in foods:
- Heme iron: Present in foods of animal origin such as red meat, liver, fish and seafood. It is easier for the body to absorb.
- Non-heme iron: It comes from plant-based foods such as legumes, nuts, cereals and green leafy vegetables. Its absorption is less efficient, but can be improved by combining it with foods rich in vitamin C.
A balanced consumption of both types of iron is essential to maintain optimal levels of this mineral in the body.
