Iron: Building Blocks for Health


Iron is an essential mineral for the body’s growth and health. It helps maintain our blood healthy by being an essential component of haemoglobin, a protein found in red blood cells that transport oxygen. Individuals with low iron levels may feel tired because there aren’t enough red blood cells to transport oxygen. Iron is also present in myoglobin, a protein that stores oxygen in muscles. It is essential for children’s cognitive development and promotes normal cell and hormone production. Inadequate iron consumption might lead to iron deficiency anaemia.


SYMPTOMS


When individuals have low iron levels, they may encounter the symptoms listed below.

  • Fatigue 

  • Weakness 

  • Dizziness 

  • Shortness of breath

  • Poor memory

  • Poor concentration

These symptoms highlight the importance of maintaining adequate iron levels for overall health and well-being. 


CAUSES


Several factors contribute to low iron levels:

  • Inadequate iron-rich food

  • Increased iron requirements due to rapid growth

  • Being pregnant

  • Menstruating

  • Excess blood loss as a result of pathologic infections, including hookworm and whipworm that lead to gastrointestinal blood loss

  • Iron’s absorption is impaired 



FOOD SOURCES 


Food contains two types of iron: heme iron and non-heme iron. Heme iron is primarily derived from the haemoglobin and myoglobin found in flesh foods like meat, fish, and poultry. Plant foods containing non-heme iron include bread, cereals, dark leafy vegetables, legumes, nuts, seeds, and eggs. 


Heme iron:

Non-heme iron:

  • Spinach

  • Potato with skin

  • Lentils

  • Beans, Nuts, seeds

  • Fortified breakfast cereals

  • Enriched rice or bread

  • Dark chocolate (at least 45%)

CONCLUSION


In summary, understanding the significance of iron for our bodies’ well-being is critical. Iron is essential for both blood health and cognitive development. Recognising the symptoms and causes of low iron levels, such as fatigue and insufficient iron dietary intake, is key to preventing iron deficiency anaemia. Incorporating a variety of iron-rich foods, both heme and non-heme, can help to maintain optimal iron levels for overall health and vitality. Remember, a well-balanced diet is essential for a healthy and energetic life.
