Determinants of maternal zinc status during pregnancy

摘要: Zinc deficiency in pregnant experimental animals limits fetal growth and, if severe, causes teratogenic anomalies. Although the data from human studies are not consistent, similar outcomes have been observed and were associated with poor maternal zinc status. This paper reviews humans of status pregnancy outcome, describes physiologic adjustments utilization during to meet needs while maintaining status, identifies dietary environmental conditions that may override those put health mother fetus at risk. Adjustments intestinal absorption appear be primary means by which retention is increased demands. However, transfer sufficient dependent on maintenance normal serum concentrations. Conditions could interfere include intake cereal-based diets high phytate, intakes supplemental iron, or any gastrointestinal disease. alter plasma concentrations transport smoking, alcohol abuse, an acute stress response infection trauma.
