The body's ability to absorb iron can be compromised by a number of foods, including Black or green teas, Soy protein, Cereal, Coffee, Eggs and Bread.


Iron Importance in Diet, Or Iron Rich Foods:

Iron must be included in the diet, because it is a necessary mineral for many vital bodily processes. Hemoglobin, the protein in charge of carrying oxygen throughout the body, cannot be produced without it. There are two types of dietary iron, known as heme and non-heme. Heme iron are animal sources of food, including meat and seafood, and it is more easily absorbed by the body. Non-heme iron, the type found in plants, requires that the body take multiple steps to absorb it. Plant-based sources of iron include beans, nuts, soy, vegetables, and fortified grains.

Some of the best sources of iron include:

  • Fortified breakfast cereals such as Weetabix, Rice Krispies and Cornflakes, Quinoa, Fortified, plain, dry cereal oats.
  • Seafood, fish and shellfish comprising tuna, mussels, and oysters.

Why Is Iron Important During Pregnancy?

Iron support to provide the developing fetus with oxygen and nutrients during pregnancy, blood volume and red blood cell production both significantly increase. While the body usually absorbs the most iron during pregnancy, an iron deficiency can result from insufficient iron intake or other factors that affect iron absorption. Premature birth, low birth weight, low iron stores, and impaired cognitive or behavioral development in infants are all risks associated with low iron intake during pregnancy. Because iron also supports the immune system, pregnant women with low iron levels may be more susceptible to infection.


Side-Effects Of Iron Deficiency, Or What Are Consequences Of Iron Deficiency?

Multiple effects of iron deficiency on general health and wellbeing are possible. These may include:

  • Weakness, decreased energy, and fatigue.
  • Anemia, which shows signs like a pale complexion, and cognitive decline.
  • Can impair children's growth and development. 
  • Weaken the immune system, and have a negative impact on pregnancy outcomes. 

To avoid long-term health issues, it is crucial to address iron deficiency through proper nutrition and, if necessary, medical intervention.


Iron Supplements:

Iron supplements are frequently used to address iron deficiency and raise iron levels in the body. They are available in a variety of dosage forms, including tablets, capsules, and liquid, and can be obtained with a prescription or without one from a healthcare provider. It is possible to raise iron levels, reduce iron deficiency symptoms, and avoid complications linked to low iron by taking supplements as directed. However, it is crucial to adhere to dosage recommendations and seek medical advice to ensure safe use and reduce any potential side effects.



One of the most crucial minerals your body needs to stay healthy is iron. Therefore, you should know, "Why is iron important for the body"Anemia can develop from iron deficiency if it is not treated. Under the guidance of a doctor, iron supplements are used to treat IDA and iron deficiency. If you are not iron deficient or anemic, supplementing with iron is almost never necessary. The best iron supplement is one that gives you the dose you require with the fewest side effects possible. Additionally, it ought to be of excellent quality, absorbent, and cost-effective.

Who should not take iron supplement?

Patients with hereditary hemochromatosis who do not receive medical treatment run the risk of developing serious conditions like liver cirrhosis, liver cancer, and heart disease. Supplements containing iron and vitamin C should be avoided by people with this condition.

Who Should Take Iron Supplements?

Adults and children over the age of 12 can both take iron supplements. The risk of iron deficiency is higher than average for some demographic groups. Among them are:

  • Young children and infants grow quickly, necessitating adequate iron levels.
  • Iron requirements for pregnant women increase during pregnancy.
  • Regular blood donors.
  • Females who experience heavy menstrual bleeding.
  • Iron deficiency is more common in cancer patients, particularly those with colon cancer.
  • Iron deficiency is more prevalent in people with heart failure. 
  • Due to dietary restrictions, people with gastrointestinal disorders like ulcerative colitis, celiac disease, and Crohn's disease are more likely to experience an iron deficiency.


What are the stages of iron deficiency?

Iron deficiency typically progresses through several stages:

  1. Storage Depletion: Blood ferritin levels are lower than anticipated. Since ferritin is the form of iron that is stored in the body, low ferritin levels are the first indication that the body's iron reserves are in danger.
  2. The second stage of iron deficiency, known as mild deficiency, is marked by a decline in the transporter of iron, called transferrin. Even though hemoglobin levels remain normal, this is frequently accompanied by a decrease in the size of red blood cells. 
  3. Iron deficiency anemia occurs when there is insufficient iron to produce hemoglobin for red blood cells. At this point, the hemoglobin concentration will be below the normal range. You may now begin to exhibit the symptoms of iron deficiency anemia. 

It is crucial to remember that these phases are not always different or linear and that the severity of iron deficiency can range from mild to severe.


Why iron is important for athlete?

Young female athletes, are more likely to suffer from an iron deficiency, especially for female endurance athletes, like marathon runners. Some experts suggest female stamina athletes should increase their daily intake of elemental iron by 10 mg in addition to the RDA. Athletes with iron deficiencies perform worse on the field and have less robust immune systems. Hemoglobin deficiency can significantly affect performance during physical activity by reducing the body's capacity to deliver oxygen to the muscles.
