Objective: 

It has been reported that fruit consumption can prevent deleterious effects of smoking. The aim of this study was to investigate the effects of smoking, fruit consumption and physical activity on lung functions and serum oxidant and antioxidant parameters in young persons.

Methods: 

This study was carried out on 164 healthy volunteers aged 18–28. Smoking, physical activity and fruit consumption status were determined with an inquiry. Pulmonary functions tests (PFT) were measured using pony spirometer. Serum malondialdehyde (MDA), total oxidant and total antioxidant levels were determined with spectrophotometry.

Results: 

Working groups non-smoker, leaving, among active-smokers, passive smokers, or, interms of PFT values did not differ significantly. Likewise, serum MDA and TOS and TAS levels were not significantly different between study groups.

Conclusions: 

In this study, there was no relationship between PFT and smoking, fruit consumption or exercise. This may be due to lack of oxidant/antioxidant imbalance in young smokers having low package-year at present. Therefore, smokers, especially having low pack-years, should be advised to quit smoking before a pulmonary disturbance occurs.
