Tea drinking and microcytic anemia in infants
The American Journal of Clinical Nutrition
|June 1, 1985
Summary
Tea consumption in infants significantly increases the risk of developing microcytic anemia. This study found higher rates of anemia and lower hemoglobin levels in tea-drinking infants, advising against its use.
Area of Science:
- Pediatrics
- Hematology
- Nutrition
Background:
- Anemia and microcytosis are prevalent in infants.
- Iron deficiency is a common cause of microcytic anemia in this age group.
Purpose of the Study:
- To investigate the association between tea consumption and microcytic anemia in infants.
- To determine if tea drinking impacts key hematological parameters in infants.
Main Methods:
- A study of 122 healthy infants aged 6-12 months.
- Routine blood counts were performed to assess hemoglobin and mean corpuscular volume.
- Tea consumption habits were recorded and compared between groups.
Main Results:
- 48.4% of infants had anemia, 21.3% had microcytosis, and 19% had microcytic anemia.
- Tea-drinking infants showed a significantly higher incidence of microcytic anemia (32.6% vs 3.5%).
- Tea drinkers had lower mean hemoglobin and mean corpuscular volume levels compared to non-drinkers.
Conclusions:
- Tea consumption is linked to a higher risk of microcytic anemia in infants.
- Giving tea to infants, especially when iron sources are limited, is not recommended.
- Further research may explore the mechanisms behind tea's effect on iron absorption in infants.
