过敏症可能与刷碗方法有关

时间:2022-5-11 作者:快乐英语网

A new study suggests that parents who wash their dishes by hand, rather than in a dishwashing machine, may unwittingly lower the likelihood that their children will develop allergies.

一项新研究表明,爸爸妈妈用手刷碗——而不是用刷碗机——可能在无意中减少小孩患过敏的可能性。

The new study, published in the journal Pediatrics, looked at whether a number of behaviors that expose children to bacteria early in life might protect them from developing allergies later on. The idea, known as the hygiene hypothesis, is that children raised in particularly sanitized environments are less likely to develop an immune tolerance to trivial threats.

这项新研究发表在《儿科学》(Pediatrics)杂志上,它研究的是一些让儿童接触细菌的行为能否预防日后出现过敏。这个看法被叫做卫生假说,它觉得在特别干净的环境中养大的小孩愈加难以对不重要的威胁产生免疫力。

The researchers followed roughly 1,000 young children and their parents living in the Gothenburg area of Sweden. They investigated behaviors like whether the parents fed their children foods purchased directly from farms, such as eggs, meat and unpasteurized milk. They looked into whether the children ate fermented foods, which have beneficial probiotic bacteria. And they looked into whether the parents washed their dishes by hand or used a dishwasher.

研究者调查了瑞典哥德堡区域约1000名幼儿及其爸爸妈妈的生活。他们调查的行为包含:爸爸妈妈是不是用直接从农场买来的食物喂养小孩,譬如鸡蛋、肉类和未经高温消毒的牛奶;这类小孩是不是食用含有益生菌的发酵食物;这类爸爸妈妈是用手还是用刷碗机刷碗。

Then they examined whether the children had allergic conditions including asthma, eczema and hay fever. Ultimately, the researchers found that children raised in households where dishes were always washed by hand had half the rate of allergies. They also discovered that this relationship was amplified if the children also ate fermented foods or if the families bought food directly from local farms.

然后他们调查这类小孩是不是患有哮喘、湿疹或花粉病等过敏症。最后,研究者发现,在一直用手刷碗的家庭长大的小孩患过敏的比率是用刷碗机刷碗的家庭的一半。他们还发现,假如这类小孩也吃发酵食物或直接从当地农场购买的食物,这种联系更为明显。

The findings demonstrated only an association, not cause and effect, so it was not clear whether these behaviors directly led to fewer allergies. But it may be the case that these behaviors expose children to innocuous bacteria, which can help strengthen their immune systems, said Bill Hesselmar, an assistant professor at the University of Gothenburg and lead author of the study.

这类发现只不过表明一种联系,而非因果关系,所以仍不清楚这类行为能否直接致使更少出现过敏。但这项研究的主要作者、哥德堡大学的助理教授比尔·海瑟玛(Bill Hesselmar)说,状况可能是,这类行为能让小孩接触无害细菌,从而提升免疫力。

Dr. Hesselmar said that while the sanitizing effect of dishwashing machines can be a good thing, the “less efficient” method of washing dishes by hand might leave behind some bacteria that could have benefits. But he said more research was needed to see if the relationship they found was real and, if so, what was causing it.

海瑟玛博士说,刷碗机的消毒用途可能是有益的,但用手刷碗这种“不那样高效”的方法或许会留下一些有益细菌。但他说,需要进行更多研究来确定他们发现的这种关系是不是属实,假如属实的话,缘由是什么。

“It’s an interesting finding and very surprising,” he said. “But we have to see if we can confirm it.”

“这是个有趣的发现,很让人意料之外,”他说,“但大家需要看看能否证实它。”
