The Importance of Iron in a Baby's Diet

Last update: 19 March, 2018

Iron in a baby’s diet is very important, mainly because it can prevent diseases such as anemia, one of the most frequent problems during the growth phase.

This mineral cannot be lacking in a baby’s diet, especially when they are between 0 and 12 months old.

According to the U.S. Institute of Medicine, it is advisable for children between the ages of 6 months to 1 year to receive 11 mg of iron each day. For children 12 to 36 months old, 7 mg per day is recommended.

To start adding iron to a baby’s diet, some foods work better than others:

Iron-rich foods

From the moment a baby starts supplementary feeding, their diet much be rich in iron. Therefore, it’s important to add foods that contain this mineral to their diet.

Here are some recommendations:

  • It is advisable to avoid milk with low iron content, such as cow’s milk, goat’s milk or soy milk.
  • It is advisable to reduce the consumption of foods that contain iron absorption inhibitors or anti-nutrients, such as fiber, calcium, oxalates, phytates and phosphates.
  • It is important to introduce food such as meat and fish in the form of a puree starting at 6 months of age.
  •  The baby should consume foods that contain Vitamin C, which helps with iron absorption.

  • It is good for the baby to eat vegetable purees, such as peas, spinach, broccoli, cauliflower and beetroot.

Iron is a mineral that is abundant in beef, poultry and fish.

Consequences of a lack of iron in a baby’s diet

A lack of iron in a baby’s diet can have many consequences, anemia being the most common. But in addition to this disease, the child may suffer from other health problems, such as:

  • Latent iron deficiency: lack of iron deposits in the body
  • Iron-deficiency anemia: can cause hematopoiesis
  • Ferropenia: lack of plasma or circulating iron levels
  • Damage to the central nervous system during the development of the cognitive and psychomotor system
  • It also affects memory and learning functions.

Each red blood cell contains iron in its hemoglobin, which is the pigment that carries oxygen to the tissues of the lungs.

How to guarantee iron consumption

Incorporating iron into a baby’s diet to avoid iron deficiency should begin at 4 or 6 months of age by introducing foods that are rich in this mineral and that favor its absorption.

The World Health Organization (WHO) recommends guaranteeing the consumption of iron in a child’s diet via fortified foods, supplementation and diversification.

The absorption of iron is more effective when it is ingested with ascorbic acid or citric acid occurs.

Vitamin C, found in oranges and other fruits, improves the absorption of this mineral in a baby’s diet. Some experts say that certain infusions and cow’s milk can inhibit the absorption of iron.

Breast milk is an excellent way to provide this mineral to your baby. After breastfeeding, a continuation formula can help provide the extra iron your child needs.

Remember that a fortified continuation formula can help supplement a balanced diet.
