Washing Dishes By Hand May Reduce Risk of Allergy Development


A study of 1,029 Swedish children between ages 7 and 8 found an association between allergy development and common lifestyle factors, such as washing dishes by hand versus using a dishwashing machine. The authors of the study, “Allergy in Children in Hand Versus Machine Dishwashing,” from the March 2015 issue of Pediatrics (published online Feb. 23), found that children whose parents washed dishes by hand were less likely to develop allergies than those whose dishes were washed using a dishwasher. Serving fermented foods or foods bought directly from a farm also lowered the risk of allergies. It’s thought that hand washing and non-processed foods expose children to more diverse microbes, which then stimulates the immune system to produce antibodies that reduce the risk of developing allergies.
