Iron Intake and Anemia: Facts Parents Should Know  

The American Academy of Pediatrics (AAP) recently released new screening guidelines for iron deficiency. Iron is essential for delivering oxygen to every organ, including the brain, and it’s necessary for the production of neurotransmitters, like dopamine. Iron deficiency can lead to symptoms ranging from weakness to disorders of sleep. 

The tricky thing about iron deficiency in a rapidly developing brain is that, once detected, the damage may already be done. Focusing on iron-rich foods when starting solid foods is, of course, essential, but you have to continue the emphasis into adulthood. 

Important Facts All Parents Should Know

You can be iron deficient without anemia. Routine screening for iron deficiency and anemia is done in toddlerhood and in teenaged girls. Anemia is defined as having a low level of hemoglobin — which is an iron-bound protein in red blood cells, responsible for delivering oxygen to tissues and carrying carbon dioxide back to the lungs. Iron stores may be running low well before hemoglobin levels drop, and what is more interesting is that mild symptoms of anemia, like fatigue, can be present with low iron stores, prior to the development of overt anemia. Doctors may order a ferritin level and iron studies to obtain a more complete picture of a patient’s iron status. 

Too much milk (or milk alternative) is a leading cause of iron deficiency in toddlers. In order to reduce the risk of anemia, I recommend toddlers transition from bottle to cup when they transition from formula or breastmilk to whole milk, usually around age 1. I also encourage limiting milk to less than 2-3 cups per day, as overconsumption of milk (or milk alternatives) limits space for iron-rich foods. 

Make iron-rich foods part of the daily routine — aim for three servings a day. As soon as solid foods are introduced, iron-rich foods should be an essential component of complementary feeding. Formula already supplies plenty of iron, but breastfed babies who aren’t eating iron-rich solids may need a supplement. Iron supplements should only be started under the supervision of your healthcare provider. 

Iron-rich foods include meats, beans, lentils, greens, tofu, seeds, whole grains and some nuts such as cashews, pine nuts, and almonds. Iron fortified foods like cereals and pastas serve as a boost for picky eaters or those needing supplemental iron. Remember that plant-based iron requires vitamin C, found in citrus and berries, for optimal absorption. Below is a reference table of daily targets by age:

Age group	Daily iron target
Toddlers (1–3 years)	7 mg/day
Young children (4–8 years)	10 mg/day
Older children (9–13 years)	8 mg/day
Teen boys (14–18 years)	11 mg/day
Teen girls (14–18 years)	15 mg/day

For vegan and vegetarian families, understanding nutrition is paramount. Reading labels and focusing on meeting all nutritional needs is difficult for most parents. If you need help, enlist the services of your pediatrician or a dietician. 

Menstruation is a major driver of iron loss. Teen girls need to stay especially vigilant about intake once periods begin as even mild, unaddressed iron loss month after month can chip away at energy, concentration, and mood over time.

Iron supplements are hard on the belly. Iron supplements can cause stomach discomfort and constipation. Sometimes, reducing the dose or taking it every other day can help with compliance. Consult your health care team before starting supplements as iron has been a cause of pediatric medication overdose.

Not all iron deficiency is diet related. Although the cause of anemia is usually nutritional dependent, chronic illness or inflammation, poor gastrointestinal absorption, or blood loss can also cause anemia. For severe cases of anemia, a detailed history and blood testing can usually help your doctor guide you appropriately. 

The Breakdown. 

Iron is necessary for oxygen delivery to all organ systems and essential for overall healthy function. Preventing iron deficiency is the best way to ensure optimal cognitive development in rapidly growing brains. In early toddlerhood, introduce iron-rich foods early and avoid excessive milk intake by discontinuing bottle use around age 12-15 months. As children get older, emphasize iron-rich foods at least three times a day, especially in vegan and vegetarian households. Discuss screening for iron deficiency and anemia with your doctor. Please do not start any iron supplementation without consulting your physician.
