Although adequate dietary intake of maternal is supposed to have beneficial effects on development of infants, it may be harmful for child growth and development since specific food is a common source of heavy metal. The purpose of the present study was to investigate antepartum and postpartum blood mercury, lead and cadmium levels in relation to maternal food intake. Among 422 pregnant women (18–20 wk), whose dietary intake during pregnancy was assessed by a 24‐hour recall method, maternal blood heavy metal levels were analyzed by atomic‐absorption spectrometry methods. Maternal whose intake of meats and vegetables were above the median value showed high in antepartum blood lead level than those with intakes below the median. Maternal whose intake of beans was above the median value showed high in antepartum blood cadmium level than those with intakes below the median. Antepartum blood lead level of maternal was positively correlated with meat and meat products intake during pregnancy. Postpartum blood mercury level was positively correlated with mushrooms and beverages intake during pregnancy. Postpartum blood cadmium level was positively correlated with seaweeds intake during pregnancy. These results suggest that food intake during pregnancy may effects antepartum and postpartum blood mercury, lead and cadmium levels of maternal.
