导读:最新研究显示,喝低脂酸奶的孕妇其婴儿患哮喘和花粉热的风险将加大,因为低脂酸奶中缺乏保护性的脂肪酸。 研究人员对7万多名丹麦妇女的饮食进行分析,并追踪他们孩子7岁之前的健康状况。研究发现,每天喝低脂酸奶的孕妇其孩子患哮喘的几率比不喝酸奶的要高出1.6倍。但该结果并不能说明牛奶摄入与哮喘有关,因为一般认为牛奶是有助于抑制哮喘的。

较为普遍的结论是孕妇产前的饮食环境对婴儿的健康有着重要的影响。专家建议怀孕妇女应当有均衡饮食,饮食要发生巨大改变之前最好先征询医生的意见。


Pregnant women who eat low-fat yoghurt can increase the risk of their child developing asthma and hay fever, a study says.

At the European Respiratory Society conference, researchers will suggest this could be due to an absence of protective fatty acids in yoghurt.

The diets of more than 70,000 Danish women were analysed and their children followed until the age of seven.

Asthma UK says pregnant women should follow a balanced diet.

'No milk link'

Pregnant women who ate low-fat yoghurt with fruit once a day were found to be 1.6 times more likely to have children who developed asthma by age seven, compared with children of women who did not eat low-fat yoghurt.

The study also found that the children of these women were more likely to have allergic rhinitis (hay fever) and current asthma symptoms.

But the results showed that milk intake during pregnancy was not linked to any increased risk of asthma.

In fact, milk was shown to protect against asthma development.

Ekaterina Maslova, lead study author form the Harvard School of Public Health, who worked with the data at the Statens Serum Institut in Copenhagen, said: "It is a puzzling finding. The absence of fatty acids in low-fat yoghurt may be key to the results.

"The results suggest that fatty acids play an important role or it could be that people who ate this kind of yoghurt had similar lifestyle and dietary patterns, but we cannot make any conclusions at this stage.

"We need to replicate these results in other studies first."

Leanne Metcalf, director of research at Asthma UK, said there is plenty of evidence to suggest that the pre-natal environment can influence a child's health.

"However, the impact of a pregnant woman's diet on her child's health continues to be debated, as it is difficult to assess how particular aspects of a woman's diet during pregnancy are linked to the risk of developing asthma and allergies.

"Eating a healthy, balanced diet at any time, but especially during pregnancy is advisable and we would recommend that pregnant women discuss any drastic changes to their diet with their GP first."
