Studies have shown that tea drinking can reduce the absorption of the non-haem iron found in cereals, vegetables, nuts and pulses. Tea is not thought to affect the absorption of the haem iron found in meat.
To minimise the risk of reduced iron absorption, those with poor iron status should avoid drinking tea with meals and at least one hour after meals. This group includes adolescent girls, women between 18 and 49, and those over 75.
