Adherence to a Mediterranean diet and using olive oil for cooking/dressing salads during pregnancy were both significantly associated with less wheezing during the first year of the infant's life.
Other factors remained associated with wheezing: male gender, day care attendance, maternal asthma, maternal smoking during pregnancy, infant eczema and mould stains on the household walls.
