英國政府宣布，將把葉酸添加到英國面粉中，以幫助預防嬰兒的先天性脊柱缺陷。

Women are already advised to take folic acid before and during pregnancy, but many don’t. It’s important because getting enough of this B vitamin cuts the risk of a baby being born with spina bifida or other neural tube defects.

早已有專家建議女性在孕前和孕期服用葉酸，但許多人并未照做。這其實很重要，因為攝入足量這種 B 族維生素可以降低嬰兒出生時患脊柱裂和其它神經(jīng)管缺陷的風險。

Mandatory fortification will mean everyone eating foods like bread in the UK, will get a dose. There was a concern that for some people, particularly the elderly, boosting folic acid might have unintended negative consequences, such as covering up the symptoms of vitamin B12 deficiency.

強制加強葉酸攝入意味著在英國，每個吃面包等食物的人都會攝入一定的劑量。有人擔心，對于一些人，特別是老年人來說，增加葉酸攝入量可能會產生意想不到的負面后果，比如可能會掩蓋維生素 B12缺乏癥的癥狀。

But the government’s independent advisory body has looked at all the evidence and is satisfied fortification is the right thing to do.

但英國政府的獨立咨詢機構已經(jīng)研究了所有證據(jù)，并認為加強葉酸攝入是正確的決策。
