Iron-rich foods are a vital part of the diet for the simple reason that iron is an essential mineral for humans to survive and lead a healthy life. Apart from other important functions, the most crucial function of iron in the body is to deliver oxygen throughout the body with the help of red blood cells. 18 mg is the daily value of iron that the body gets mainly through iron-rich foods. The body stores its iron reserves through iron-rich foods, not to face any deficit at times of need. The iron reserves built through the consumption of iron-rich foods regularly also ensure the iron-absorbing capacity of the body.

Consequences of Low Iron-Rich Foods in The Diet-
Iron-deficiency anemia is the most common form of anemia, indicating a decrease in red blood cells caused by deficient consumption of iron-rich foods. Without sufficient iron, the body can not produce enough hemoglobin, a substance in red blood cells that makes it possible for the RBCs to carry oxygen to the bloodstream and deliver it to all the parts of the body.
As a result of low levels of iron reserves or low consumption of iron-rich foods, one may feel fatigued, tired, or irritated. About 50% of pregnant women, 20% of women in general, and 3% of men face iron deficiency due to a lack of iron-rich foods in their diet. According to the World Health Organization, Iron deficiency is the most common nutrient deficiency mainly present in the developed nations. The only solution to cope with low iron reserves is to add more iron-rich foods to the diet.
Heme Iron or Non-Heme Iron, which Has More Iron-Rich Foods?
Foods with iron contain two types of iron — Heme and Non-heme iron. Meat, poultry, and fish have a high content of heme iron. Heme iron present in iron-rich foods is the type of iron the human body can readily absorb without much difficulty. Up to 30 percent of the heme iron is easily consumable. Generally, eating meat stocks up the iron reserves faster than other iron-rich foods. Non-heme iron-rich foods are plant-based foods such as vegetables, fruits, and nuts.
Foods rich with iron, particularly with non-heme iron, are still vital to a nutritious and well-balanced diet. However, non-heme iron is not efficiently consumable in the body. Only 10 percent of iron is consumable out of these iron-rich foods. Heme iron-rich foods are more popular iron-rich foods because of their fast absorption capacity in the human body. Other nutrients like vitamin C, abundantly present in tomatoes, orange, lemon, and red, yellow, and orange peppers – can stimulate the absorption of non-heme iron foods to make them iron-rich foods truly.
The Daily Requirement of Iron in The Body-
- Older women- 8 mg
- Young women (age 19 – 51)- 18 mg
- Pregnant women- 27 mg
- Men- 8 mg
- Infants and children- 7 mg- 16 mg (depending upon the age and height)

Researchers suggest that people who regularly eat iron-rich foods like meat, fish, or poultry are less prone to iron deficiency. In fact, red meat is perhaps the single most easily accessible heme iron source, making it a potential iron-rich food source for people prone to anemia. A study about good sources of iron was conducted on some women. It revealed that women eating meat retained good iron stores compared to those who consumed iron supplements. Meat is thus among the top iron-rich foods for women and adults.
2. Oysters and Clams- Shellfish is a Tasty Iron-rich Food Source.

Iron is a nutrient that the body cannot produce on its own. Hence it is vital to incorporate iron-rich foods into the daily diet to avoid iron deprivation or deficient iron reserves. However, the amount of iron should be regulated, especially heme iron. A too low or too high amount of iron in the body may impact health and even intensify underlying diseases. Iron absorption is also a problem faced by many people. People who eat plant-based iron-rich foods must add vitamin C foods to ensure seamless iron absorption by the body. This is why it becomes important to consult a doctor or a nutritionist to decide upon the daily iron requirements and the appropriate iron-rich foods.
