以碳水化合物为主饮食可能导致更年期提前

A diet high in carbs could bring on an earlier menopause, a study suggests.

一项研究表明，碳水化合物高的饮食会导致更年期提前。

Eating lots of pasta and rice was associated with reaching menopause one-and-a-half years earlier than the average age of women in the UK of 51.

英国妇女的平均更年期年龄为51岁，而以面食和大米为主的英国妇女与一般妇女相比，更年期到来的时间会提前一年半。

However, the University of Leeds study of 914 UK women, also found that a diet rich in oily fish and peas and beans may delay natural menopause.

然而，利兹大学对914名英国女性的研究也发现，富含高油脂鱼类、豌豆和豆类的饮食可能会延缓自然更年期。

But experts say many other factors, including genes, influence timing of the menopause.

但专家说，包括基因在内的许多其他因素也会影响更年期的时间。

It's not clear how big a contribution dietary choices might make and women should not worry about changing what they eat based on the findings, they add.

他们补充道，目前还不清楚饮食选择会有多大关联，而女性不应该担心该调查结果并改变她们的饮食。

The research was published in the Journal of Epidemiology And Community Health and the women were asked what their typical diet contained.

该研究发表在《流行病学与社区卫生杂志》上，研究中女性们被问到了她们的典型饮食包含什么。

The researchers took into account other potentially influencing factors, such as a woman's weight, reproductive history and use of HRT, but they weren't able to consider genetic factors, which can influence age of menopause.

研究人员考虑了其他潜在的影响因素，如女性的体重、生育史和荷尔蒙替代疗法的使用，但他们无法衡量能够影响更年期的遗传因素。

The study is observational and cannot prove any cause, but the researchers offer some possible explanations behind their findings.

这项研究是观察性的，并不能直接证明饮食与更年期的关系，但研究人员提供了一些可能的解释。

For example, legumes contain antioxidants, which may preserve menstruation for longer. Omega-3 fatty acids, which are in oily fish, also stimulate antioxidant capacity in the body.

例如，豆类含抗氧化剂，可以延长月经时间。油性鱼类含有Omega-3脂肪酸，可以促进抗氧化剂对身体的作用。

Refined carbs boost the risk of insulin resistance, which can interfere with sex hormone activity and boost oestrogen levels.

精制碳水化合物会增加胰岛素抵触的风险，这可能会干扰性激素的活性并增加雌激素水平。
