绿色蔬菜、水果和坚果一般都含有叶酸,这种维生素B能帮助身体制造健康的新细胞。大多数孕前维生素包括叶酸,因为叶酸能预防神经管形成中产生缺陷,而神经管是神经中枢的前身。

Green, leafy vegetables, fruits and nuts naturally contain folate, a B vitamin that helps the body make healthy new cells. Most pre-natal vitamins include folic acid because it protects against defects in the formation of the neural tube, the precursor to the central nervous system.
绿色蔬菜、水果和坚果一般都含有叶酸,这种维生素B能帮助身体制造健康的新细胞。大多数孕前维生素包括叶酸,因为叶酸能预防神经管形成中产生缺陷,而神经管是神经中枢的前身。

Dr. Pal Suren is with the Norwegian Institute of Public Health:
Pal Suren就职于挪威国家公共卫生研究院。

“The neural tube is the origin of the human brain in the fetus and closes very early in development, and the neural tube defect is when this tube doesn’t close properly," said Suren.
“神经管是胎儿人脑的发源点,与发育密切相关,如果管道无法适当关闭,神经管就出现缺陷。”

Neural tube defects include spina bifida, a defect of the spine, as well as some brain defects. Since taking folic acid supplements before or right after becoming pregnant prevents these defects, Dr. Suren and his colleagues wanted to find out if the supplements could also prevent autism. They asked thousands of pregnant women to record all dietary supplements they took. After the children were born, the researchers reviewed the rate of autism.
神经管缺陷包括脊柱裂,这种脊柱上的一种缺陷,以及一些大脑缺陷。孕前或孕后服用叶酸补充品能预防这些缺陷,Suren和同事希望研究这些补充品是否能预防孤独症。他们要求数千名孕妇记录下全部膳食补充,等婴儿降生后,研究者就会研究孤独症的发病率。

“We went back to the data we had from early pregnancy and compared those mothers who had taken folic acid to those who hadn’t  taken any folic acid," he said.
“我们利用怀孕早期获得的数据,将服用叶酸的母亲与没有服用的母亲作对比。”
