Iron in your baby's first foods

If starting solids has one secret main character, it's iron. It's the reason the first purée in Germany is a meat purée – and why “she only eats fruit pouches” isn't a good idea in the long run.

In short: around the 6th month the inborn iron store runs out and breast milk replenishes little – so iron belongs in first foods from the start. Best source: meat (haem iron). Plant-based: oats, millet, legumes – always combined with vitamin C (fruit purée, bell pepper), which clearly improves absorption.

Why iron of all things?

In the last third of pregnancy the baby builds up an iron store that it lives off for the first months. Around the 6th month this store is largely used up – and right now the brain is growing rapidly and needs iron for myelin formation and development. Breast milk is brilliant at almost everything, but low in iron. The conclusion of all the expert bodies (Gesund ins Leben, ESPGHAN, AAP): solids must deliver iron from the very beginning – which is why the three-purée plan starts with the vegetable-potato-meat purée.

Iron sources for babies – the table

FoodType of ironPractical for babies
Beef, lambHaem (very well absorbed)Cooked soft, finely puréed into the lunchtime purée – even small amounts count
PoultryHaemMild in taste, a good way in
OatsPlant-basedAs cereal purée or in fruit purée – the everyday classic
MilletPlant-basedThe most iron-rich common cereal, as purée flakes
Lentils, chickpeas, beansPlant-basedCooked soft and puréed (well cooked they are easy to digest)
Whole grains, whole-grain breadPlant-basedFrom the lumpy-food stage also as a soft bread crust
TofuPlant-basedCooked soft, puréed – the vegetarian meat substitute in purée
Egg yolk (cooked through)MixedAlso an important allergen to introduce

The vitamin C trick

Plant-based (non-haem) iron is absorbed much better when vitamin C is part of the same meal. In practice that means: a few spoonfuls of fruit purée in the oat porridge, bell pepper or broccoli in the vegetable purée, a sip of heavily diluted orange juice with the cereal meal. Conversely, calcium (milk) inhibits absorption from the same meal – which is why the lunchtime purée is traditionally dairy-free and the milk-and-cereal purée is a separate meal in the evening.

⚠️ No iron supplements on your own initiative. Whether a baby needs extra iron (e.g. as a premature baby) is for the paediatrician to decide – too much iron is harmful to infants as well. Noticeable paleness, tiredness or weak feeding belong in the doctor's office, not in self-diagnosis.

Vegetarian works – with a system

According to Gesund ins Leben, a vegetarian approach to solids works well: instead of meat, whole-grain cereal (oats, millet), legume purée or tofu goes into the lunchtime purée – consistently with a vitamin C partner. A vegan infant diet, on the other hand, is risky without professional supervision (B12!) and belongs in the hands of a doctor or dietitian.

The iron compass in the app

So you don't have to do sums while feeding, HeyFini marks good iron sources in the food catalogue with an iron symbol – complete with a vitamin C note in the food profile. In the food passport you then see at a glance how often iron-rich foods have been on the menu lately.

Frequently asked questions

What does a baby need iron for in the first place?

Above all for the brain (development, myelin formation) and for making blood – and the inborn store is empty around the 6th month.

Is a vegetarian purée enough?

Yes, if it's well thought out: whole grains/legumes/tofu plus vitamin C. Regularity is what matters.

How often should meat go into the purée?

The Gesund ins Leben network recommends meat in the lunchtime purée on several days a week; on meat-free days, cereals and vegetables with vitamin C take over.

Does tea inhibit iron absorption?

Black/green tea inhibits it markedly – unsuitable for babies anyway. Water is the drink with meals.
