妇女妊娠期营养缺乏十分常见,许多孕妇因不了解妊娠期的生理及生化改变而盲目摄入大量不必要的维生素及矿物质。虽经数十年的研究,目前仍不能准确地指导营养良好的妇女在怀孕期摄取必需营养物。近年来,人们对妊娠期妇女比较注重补充锌和镁。众所周知,动物缺乏微量元素可以出现生殖方面的问题,人类缺少微量元素(除先天及其它代谢异常外)出现生殖方面的问题却很少有人报道。八十年代初期,锌变成了时髦的微量元素,有人提出妊娠期补锌疗法。尽管镁不是微量元素(是人体第四种常见离子),其在人体内的作用机制与许
Nutritional deficits during pregnancy are very common in women. Many pregnant women blindly consume large amounts of unnecessary vitamins and minerals for lack of understanding of the physiological and biochemical changes during pregnancy. After decades of research, it is still not possible to accurately guide the well-nourished woman’s intake of essential nutrients during pregnancy. In recent years, people pay more attention to supplement zinc and magnesium in pregnant women. It is well-known that lack of trace elements in animals can cause reproductive problems. There are few reports of reproductive problems in humans lacking trace elements (except for innate and other metabolic disorders). In the early 1980s, zinc became a trendy trace element, and some proposed zinc supplementation during pregnancy. Although magnesium is not a trace element (the fourth common ion in the body), its mechanism of action in humans
