  • Normal values were taken as 10% below Caucasian values.

  • Two subjects were excluded because of poor quality blows.

  • * Cumulative exposure during the cooking period in the morning and evening.

  • AEC, after evening cooking; AMC, after morning cooking; BEC, before evening cooking; BMC, before morning cooking; COPD, chronic obstructive pulmonary disease; FEV1, ean forced expiratory volume in 1 s; FEF25–75, forced expiratory flow between 25% and 75% of FVC; FVC, forced vital capacity; SAD, small airways disease.
