Washing dishes by hand may lower allergy risk
If you wash your dishes by hand rather than in the dishwasher, you could be helping your children to become more resistant to allergies.
At least that's the conclusion of a study done in Sweden, which suggests that hand-washed dishes contain more bacteria and that that can help children become less prone to developing allergies.
The researchers analyzed data from more than 1,000 children living in two regions of Sweden. The data came from questionnaires that parents completed about whether their child had eczema, asthma, or seasonal allergies. They were also asked about their dishwashing practices and how much fermented or farm-fresh foods their child ate.
They found that children whose parents washed dishes by hand were 40 percent less likely to develop allergies than kids in homes that used a dishwasher.
But the scientists, whose study was published in the journal Pediatrics, said more research is needed before hand-washing dishes can be recommended as an allergy-prevention strategy.
