叶酸是水溶性维生素 B族的一种,在绿叶蔬菜、水果及动物肝脏中储存丰富。叶酸对于每一个细胞的分裂都是必要的,尤其对骨髓中血液红细胞的生成是必需的。叶酸参与人体新陈代谢的全过程,是合成人体重要物质DNA的必须维生素。医学研究发现,叶酸是胎儿神经发育的关键营养素。叶酸不足,除了会抑制细胞分裂而影响到红血球的制造,还可以导致胎儿神经管畸形外,还可使眼、口唇、腭、胃肠道、心血管、肾、骨骼等器官的畸形率增加。

叶酸不储存于体内,且易自水中流失也易受高温破坏。叶酸易被紫外线破坏,因此,新鲜蔬菜在室温下贮藏 2 至 3 天其叶酸量会损失 50 至 70%。食物中 50 至 95% 的叶酸在烹调时被破坏。叶酸缺乏症在全世界被公认为一个保健问题。婴儿,青少年和孕妇特别容易受到叶酸缺乏的危害。

妇女怀孕前一个月到怀孕后三个月期间,每天服用 O.4 毫克的叶酸增补剂可以预防胎儿大部分神经管的畸形的发生。

叶酸的作用:

1. 维持正常的细胞分裂过程;
2. 预防巨红血球性贫血的发生;
3. 帮助胎儿发育,预防胎儿神经管畸形的发生;
4. 预防某些心脑血管疾病的发生;
5. 有助于稳定精神状态 。

缺乏叶酸症状:

1. 早产,流产,胎儿神经管的畸形;
2. 巨红血球性贫血;
3. 舌炎,长舌疮;
4. 肠胃功能紊乱,虚弱无力;
5. 失眠,躁动不安,健忘,迷糊。
