Investigation of the amount of dissolved iron in food cooked in Chinese iron pots and estimation of daily iron intake.
The amount of dissolved iron in food cooked in Chinese iron pots and that in food cooked in aluminum, stainless steel, and clay pots were determined. It was found that the amount of dissolved iron in food cooked in Chinese iron pots was two to five times higher than that in food cooked in the other types of pots. According to the test results, the estimated increase in daily iron intake was about 14.5 mg for adults and 7.4 mg for children when Chinese iron pots were used.
