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.

然后他们调查这些孩子是否患有哮喘、湿疹或花粉病等过敏症。最后，研究者发现，在一直用手洗碗的家庭长大的孩子患过敏的比率是用洗碗机洗碗的家庭的一半。他们还发现，如果这些孩子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.

这些发现只是表明一种联系，而非因果关系，所以仍不明确这些行为能否直接导致更少出现过敏。但是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，情况可能是，这些行为能让孩子接触无害细菌，从而提高免疫力。
