Iron requirements increase with age
At the 8-month child health visit, iron-fortified foods are recommended to all parents of young children according to national guidelines. Many parents understand the importance of this and make sure iron becomes part of their child’s daily diet. However, as the child grows older and begins eating regular family meals, the focus on iron often fades.
What many people are not aware of is that a child’s need for iron actually increases with age. Because infants eat very small amounts of food while having a high iron requirement, it is especially important that meals are nutrient-dense and rich in iron.
In theory, it should become easier to meet a child’s iron needs as they grow older and the amount of food on the plate increases. In practice, however, once children begin choosing what they eat, iron-rich foods are often left out. It is not uncommon for foods such as meat to be replaced by pasta, pancakes, or yogurt. As a result, even if energy needs are met, iron intake may still fall below recommended levels.
Iron deficiency develops slowly, but is often noticed too late
Growth itself, and especially brain development, requires large amounts of iron, and this process continues well into adolescence.
According to a Swedish study, 71.5 percent of upper secondary school girls had iron deficiency based on Scandinavian reference values. This does not occur suddenly, but is often the result of insufficient iron intake over a long period of time.
In a survey conducted by the Swedish National Food Agency, 10 percent of girls in fifth grade, aged 11 to 12 years, had iron levels indicating a risk of iron deficiency. This is perhaps not surprising, given that more than one in three four-year-olds had an iron intake below average requirements, and 40 percent of 1.5-year-olds were also below this level. This means their intake was likely insufficient to meet the body’s needs.
Iron deficiency does not develop overnight. It is a slow process that often begins early in life. It develops quietly and can follow a child into later years, often unnoticed until symptoms such as fatigue, paleness, or difficulties with concentration appear.
A small effort with a big impact
The good news is that iron deficiency can be prevented. By maintaining a focus on iron even beyond the toddler years, and by ensuring that a child’s diet aligns with official dietary guidelines, neither more nor less, parents can help make sure their children get enough iron. It is about making conscious everyday choices to give the body and brain the right conditions to grow, develop, and thrive.
*Here it is important to distinguish between average requirement and recommended daily intake, as they are not the same. The average requirement is the level of a nutrient that is considered sufficient to meet the needs of half of the individuals in a specific group. It is commonly used in nutrition studies to assess the risk of inadequate intake within a population. The recommended daily intake, on the other hand, is the level that is considered sufficient to meet the needs of the vast majority of individuals in a given group.
