Iron absorption

1. Foods that reduce non-haem iron absorption:
   • – Tea (decrease by > 60%)
   • – Coffee (decrease by > 35%)
   • – Phytates
2. HCl secreted in gastric juice liberates Fe3+ from non-haem iron and serves to increase solubility of dietary non-haem iron.
3. pH of duodenum is most conducive for absorption of iron.
4. Most common site of iron absorption – duodenum
