Methods: Forty male smokers with clinical diagnosis of COPD (Group-I (GI)) and 36 healthy smokers without COPD (Group-II (GII)) were included in this study. We compared the dietary habits and food intakes of the two groups using an adaptation of the Arizona Food Frequency Questionnaire (AFFQ). Question form included a list of 65 food items formed from five main food groups (grain, meat and alternatives, dairy products, vegetables-fruits and fat) and 25 dietary habits. The data were evaluated by binary logistic regression analysis, receiver operating characteristic (ROC) curve, Kolmogorov-Smirnov, Student's t, Mann-Whitney, and Chi-square tests. Results: When both groups compared, black tea consumptions (GI-700 ml; GII-1600ml (OR: 0.635, P < 0.001)), vegetable fruits scores (GI-54.30; GII-63.81 (OR: 0.863, P < 0.001)), regularly breakfast habit (GI-24 patients; GII-36 cases (OR: 0.549, P < 0.001)) and eating salty (GI-22 patients; GII-5 cases (P < 0.001)) made significant differences. In ROC curves, the area under the curve of black tea (0.898 (95% CI: 0.819-0.977) and vegetables-fruits (0.833 (95% CI: 0.727-0.938) provided high accuracy to distinguish between COPD group and controls (P < 0.001). Conclusions: High intakes of black tea and vegetables-fruits consumptions may be protecting male smokers from developing COPD.
