Iron
Why do we need iron?
Iron is a mineral that plays a crucial role in many different body functions. It helps to carry oxygen throughout the body in the form of haemoglobin (component of red blood cells that transport oxygen to tissues) and myoglobin (protein that carries oxygen to muscle) and fight off infection. It is an integral part of many proteins and enzymes and helps in energy metabolism.
How much iron do you need?
Some groups of people need more iron than the other. ICMR recommends 9 mg of iron per day for children from 1 to 3 years of age, 13 mg for children from 4 to 6 years of age, 16 mg for 7-9 years of age. The increase in iron requirements with age in children is because of increased iron requirements for skeletal growth, lean body mass and blood expansion in the body.
For adolescent boys from 10 to 17 years of age, 21-28 mg of iron per day and for adolescent girls for the same age group, 26-27 mg of iron is recommended. In adolescent age, additional iron is required for the growth spurt (blood volume expansion, increase in haemoglobin concentration and muscle mass) and in females, extra iron is also needed to account for menstrual losses.
For adult males, 21 mg of iron and for adult females, 17 mg of iron is recommended.
Pregnant woman are recommended to have 35 mg of iron. Their iron needs increase as more iron is needed considering iron needs of foetus’ growth, expansion of mother’s tissue and blood loss. Lactating mothers are recommended to have 21 mg of iron per day considering requirement of the mother and to make up for the iron lost in breast milk.
