What can decrease absorption of iron?

You can improve your body's absorption by eating foods containing vitamin C, vitamin A, along with meat, fish, and poultry during your meals. On the other hand, foods containing phytates (cereals and grains), calcium (milk and dairy), and polyphenols (tea and coffee) can hinder iron absorption.

What causes poor absorption of iron?

Malabsorption is when your body can't absorb iron from food, and is another possible cause of iron deficiency anaemia. This may happen if you have coeliac disease, a common digestive condition where a person has an adverse reaction to gluten, or surgery to remove all or part of your stomach (gastrectomy).


What inhibits iron absorption the most?

The most important inhibitors of iron uptake are phytic acid/phytates, polyphenols/tannins, proteins from soya beans, milk, eggs, and calcium. Oxalic acid/oxalate does not seem to influence iron uptake.

What foods are iron blockers?

The following foods can interfere with iron absorption:
  • tea and coffee.
  • milk and some dairy products.
  • foods that contain tannins, such as grapes, corn, and sorghum.
  • foods that contain phytates or phytic acid, such as brown rice and whole-grain wheat products.

Are eggs an iron blocker?

The iron content in eggs has limited bioavailability (13) because it is tightly bound to phosvitin (11), which is not readily degraded by proteolytic enzyme digestion (14). Moreover, whole eggs and egg whites inhibit iron bioavailability (15–17), reducing dietary absorption in adults by up to 27% (18).
