Ms. F has been diagnosed with iron deficiency anemia. The nurse has been working on ways to increase the amount of dietary iron she consumes because iron supplements cause gastrointestinal upset
During a review of her diet history, Ms. F states that she drinks several cups of tea daily. The nurse recommends no tea within one hour of eating an iron-rich meal because:
1. One cup of tea can decrease iron absorption by 50–60%.
2. Tea will cause increased urinary loss of iron.
3. Tea can increase the absorption of iron by 50–60%.
4. Iron requires an alkaline environment for absorption.
1
Rationale: One cup of tea can reduce iron absorption by 50–60% when consumed within one hour of an iron source. Tea will not cause increased urinary loss of iron. An alkaline gastric environment will reduce iron absorbability because the iron is not converted to the more readily absorbed form that requires an acidic environment.
