準媽媽應控制自己不吃薯片,保護寶寶

Scientists found that omega-6 fat in crisp fat affects growth and development of rats' unborn babies and causes uterus contractions.

科學家發現：薯片中的歐米茄6脂肪會影響懷孕大鼠未出生寶寶的生長髮育，並導致子宮收縮。

Eating too many crisps during pregnancy could have a negative effect on the development of the baby, a study suggests. Crisps contain an omega-6 fat called linoleic acid that was previously thought to have health benefits such as lowering blood cholesterol.

一項研究表明：孕期吃太多薯片或對寶寶的發育帶來負面影響。薯片含有一種叫做亞油酸的歐米茄6脂肪。以前，人們認爲亞油酸能帶來健康益處，如降低血液中的膽固醇。

But researchers found that feeding rats with three times the recommended daily intake of linoleic acid decreased hormones that regulate the growth and development of their unborn babies. It also affected their liver function and increased proteins that cause contractions in the uterus, according to the findings published in The Journal of Physiology.

但研究員發現：每天給大鼠投喂亞油酸（日常建議量的三倍），其調節未出世小鼠生長髮育的激素水平有所下降。據發表在《生理學雜誌》上的研究結果所示，它們的肝功能也受到了影響，導致子宮收縮的蛋白質有所增加。

Up until recently, people were started to consume omega-6 fats because it was thought to help to reduce blood cholesterol. And vegetable oil, which also contains linoleic acid, was marketed as a healthy and cheaper alternative to using animal fats in cooking.

直至最近，人們纔開始攝入歐米茄6脂肪，據稱，歐米茄6脂肪有助於降低血液中的膽固醇水平。含有亞油酸的植物油也被市場營銷爲替代動物脂肪的健康、低價選擇。

Study senior author Dr Deanne Skelly, of Griffith University, said: "It is important for pregnant women to consider their diet, and our research is yet another example that potentially consuming too much of a certain type of nutrient can have a negative impact on the growing baby."

該研究的資深作者，格里菲斯大學的迪安·史蓋利（Deanne Skelly）博士說道："飲食對孕婦很重要，我們的研究是過量攝入特定營養物或對嬰兒發育造成負面影響的又一例證。"

The research team at Griffith University in Queensland, Australia, fed rats for 10 weeks on a diet with high linoelic acid and mated them. They then investigated the effects of the diet on their pregnancy and the development of their offspring.

位於澳大利亞昆士蘭格里菲斯大學的研究團隊連續10周給大鼠投喂高劑量的亞油酸，並讓它們進行交配。之後，他們研究了飲食對懷孕及後代發育的影響。

The team also found rat mothers who ate a high linoleic acid diet had a reduced number of male babies. It is not known whether the same effects would be seen in humans or what amounts of linoleic acid would be harmful.

研究小組還發現，攝入高劑量亞油酸的大鼠媽媽所生的雄鼠數量減少。目前尚不清楚當被試對象是人類時，是否會出現同樣的效果，也不清楚多大劑量的亞油酸會對人類造成傷害。
