Iron-deficiency anemia is the most common type of anemia in infants and young children. Its fundamental cause is insufficient iron in the body, leading to reduced hemoglobin synthesis and resulting in microcytic hypochromic anemia. So, what are the risks of iron-deficiency anemia in babies?
Extensive research shows that iron deficiency can affect various functions in infants and young children, including growth and development, motor skills, and immunity.Iron deficiency can cause decreased appetite in babies, with some developing pica (eating non-food items). Others may experience stomatitis or glossitis, and severe cases can lead to atrophic gastritis or malabsorption syndrome. Severe iron deficiency damages the nervous system, impairing cognitive, learning, and behavioral development in infants and young children. These effects can persist into childhood and are irreversible; iron supplementation cannot fully restore impaired cognitive and behavioral functions.According to UNICEF reports, children with iron-deficiency anemia have IQs averaging 9 percentage points lower than healthy children. Studies in China show that motor and cognitive development indices of anemic children lag significantly behind their peers, indicating substantial and long-term impacts on academic achievement and future employment prospects.
Iron deficiency anemia weakens the body's immune function, increasing children's susceptibility to infections. Simultaneously, iron deficiency heightens intestinal absorption of toxic heavy metals like lead and cadmium, causing further harm.
To correct iron-deficiency anemia in children, five key dietary principles should be followed to ensure timely replenishment of daily iron requirements:
Dietary Principle 1: Incorporate iron-rich foods
Infants over 6 months old begin complementary feeding. In addition to breast milk or formula, they consume foods like eggs, vegetable purees, and minced meat.Among these, animal liver and blood contain the highest iron levels at 10–25 mg/100g—roughly ten times that of poultry, livestock, or fish (1–3 mg/100g). Eggs concentrate iron in the yolk, with levels comparable to meat. Next are leafy greens, led by rapeseed greens at 5.9 mg/100g;followed by shepherd's purse and amaranth. Spinach, commonly believed to be rich in iron, contains only 2.9 mg/100g—less than half the amount in rapeseed. Dairy products, a daily staple for babies, have relatively low iron content, roughly one-tenth that of meat. Thus, both plant-based and animal-based foods in baby's complementary diet offer significant iron sources.
Dietary Principle #2: Select Iron-Rich Foods with High Absorption Rates
Beyond focusing on iron content, it's crucial to prioritize iron absorption efficiency in a baby's diet. Iron in food exists in two forms: easily absorbed heme iron (also called porphyrin iron) and poorly absorbed inorganic iron.The iron found in animal liver, blood, poultry, meat, fish, and egg yolks mentioned earlier is heme iron. Babies absorb this type easily, making it highly effective for iron supplementation. In contrast, the iron in vegetables and dairy products is non-heme iron. Although vegetables contain significant iron, babies absorb only a small portion of it, resulting in less effective iron supplementation.
Dietary Principle Three: Timely and Appropriate Introduction of Solid Foods
Starting at 6 months, exclusive breastfeeding or formula feeding alone can no longer fully meet a baby's growing nutritional needs. Solid foods must be introduced at this stage. For example, when adding boiled egg yolk, begin with 1/4 of an egg daily, gradually increasing to 1/3, 1/2, 3/4, until reaching one whole boiled egg per day.From 8 months onward, introduce minced lean meat, liver puree, fish paste, and animal blood, also starting small and gradually increasing portions. Vegetables are essential for babies after 6 months. Blanching leafy greens in boiling water removes most oxalic acid, enhancing iron absorption.
Dietary Principle 4: Supplementing Vitamin C
Vitamin C is iron's ideal partner. While providing iron-rich foods, ensure your baby also consumes ample vitamin C-rich fruits and vegetables to enhance iron absorption. High-vitamin C fruits include kiwis, fresh jujubes, and citrus fruits.
Dietary Principle 5: Pay Attention to Cooking Methods
Research shows that iron in fermented foods is more easily absorbed. For instance, iron in steamed buns, fermented cakes, and bread is more readily absorbed by babies. Therefore, feeding these staple foods is more suitable than ordinary noodles, pancakes, or rice.When serving leafy greens to babies, blanch them briefly in boiling water first to remove most oxalic acid, allowing babies to absorb more iron.
