Abstract
We undertook a population-based study to examine the association between smoking status and nutrient and food group intakes among Japanese adults. A total of 5,350 participants who were at least 40 years of age took part in this study. Nutrient and food group intakes were examined using a validated, brief-type self-administered diet history questionnaire (BDHQ) ; smoking status was self-reported. The associations between nutrient and food group intakes and smoking status were analyzed. Among the men and women, 42.3% and 8.6%, respectively, were current smokers, and in both sexes current smokers were younger than never-smokers. Current smokers had a higher consumption of alcoholic and non-alcoholic beverages than never-smokers, whereas current smokers consumed significantly less antioxidants, dietary fiber, minerals, green-yellow vegetables, and fruit. Ex-smokers, accounting for 42.3% of the men and 5.6% of the women, had a higher intake of alcoholic beverages, but there were no gender differences in the intake of beta-carotene and green-yellow vegetables. Our results confirm that Japanese smokers have unhealthier dietary habits than non-smokers.
