想生健康儿 育龄女性要吃足够叶酸
路透社亚特兰大健康消息 美国疾病控制和预防中心的一份报告指出：针对美国密歇根州739名18-44岁育龄妇女的调查发现，仅仅42%妇女每天补充复合维生素或叶酸，只有30%妇女知道叶酸的重要性。70%的美国女性不了解孕前补充叶酸可以降低新生儿先天缺陷的危险性。这些对叶酸的重要性不甚了解的女性往往是未婚、吸烟、受教育程度低、年轻、肥胖者，她们很少进食水果和蔬菜者，几乎不可能从食物补充剂中获取叶酸。
叶酸是在谷物和多叶绿色植物等食物中存在的一种B族维生素物。科学研究认为，妇女在孕前和早孕期间补充叶酸可以预防婴儿先天缺陷。美国公共卫生署在1992年已经推荐育龄女性每天要摄取400微克叶酸。1996年，美国食物药品和药物管理局(FDA)要求所有添加营养的谷类产品必须进行叶酸强化。
密歇根州卫生厅的卡斯修斯·洛凯特博士说，婴儿先天缺陷往往在女性知道其怀孕之前就已经发生了。因为在所有怀孕妇女中有一半是意外怀孕的，如果不在怀孕前就补充叶酸，等发现自己怀孕，婴儿先天缺陷已经发生，无法补救了。因此，应该鼓励所有育龄女性每天从强化食物或补充剂中摄取400微克叶酸，保持健康饮食包括增加摄入水果和蔬菜的量，保证摄入均衡、富含叶酸的健康食物。

Many Women Don‘t Know Why They Need Folic Acid
ATLANTA (Reuters Health) - About 70% of women in the US do not understand the importance of eating enough folic acid before pregnancy so as to reduce the risk of birth defects in their newborns, according to a report from the Centers for Disease Control and Prevention (news - web sites) (CDC).
Those women least likely to understand why folic acid is important were those with less education, who were unmarried or were current smokers. Women who were younger, obese, had less education, and consumed few fruits and vegetables were the least likely to take folic acid in supplement form.

Folic acid, a B vitamin found in foods such as grains and leafy greens, is thought to prevent birth defects in babies if consumed before and during early pregnancy. In 1992, the US Public Health Service recommended that women capable of becoming pregnant consume 400 micrograms of folic acid daily. And in 1996, the US Food and Drug Administration (news - web sites) mandated that all enriched cereal grain products be fortified with folic acid.
The survey of 739 Michigan women of reproductive age (18 to 44 years) found that only 42% of the women took a multivitamin or folic acid supplement daily and just 30% knew why folic acid was important. The findings are reported in the March 16th issue of the CDC‘s Morbidity and Mortality Weekly Report.

``Because (birth) defects often occur before a woman knows she is pregnant, all women of childbearing age should be encouraged to maintain a healthy diet that includes increasing their consumption of fruits and vegetables (and) supplementing with fortified foods and vitamins,‘‘ Dr. Cassius Lockett, of the Michigan State Health Department, told Reuters Health.
``Because approximately 50% of pregnancies are unplanned, all women of childbearing age should be encouraged to consume 400 micrograms of folic acid from fortified foods and/or supplements and to consume a balanced, healthy diet of folate-rich foods,‘‘ CDC researchers write.
