Abstract

Background Previous studies have shown that cigarette smoke contains many oxidants and free radicals, which, can increase lipid peroxidation. Aim of the study The association between smoking, food pattern, especially vitaminintake and plasma concentrations of important antioxidants, as well as, lipid peroxidation products was assessed in this, cross-sectional study., Subjects and methods Sixty Austrian women aged 18-40 y were enrolled in the study. Twenty-nine women were allocated to the smoking, group; thirty-one women served as nonsmoking controls. Plasma concentrations of (alpha- and gamma -tocopherol, alpha- and beta -carotene, lycopene, cryptoxanthin, retinol,ascorbate and malondialdehyde were determined by HPLC; dietary intake and food pattern had been assessed by four 24-h dietary intake recalls and one food frequency questionnaire. Results Generally, food intake patterns were not different between smoking and nonsmoking women. But, a significantly higher intake of alcohol was observed in the smoking group (P < 0.05). Plasmaascorbic acid concentration of the smoking group did not differ from the nonsmoking women. Despite the increased utilization because of the oxidativestress in smokers, this result might be explained by the high dietary intake of vitamin C in our smoking group. Significantly lower plasma concentrations of alpha-, beta -carotene and lycopene have been partly ascribed to the enhanced metabolic turnover resulting from smoking-induced oxidative stress. Our results confirm that smoking had no effects on plasma tocopherol and plasma retinol concentrations. Conclusions The poor supply with the carotenoids (alpha-, beta -carotene and lycopene may result from the increased metabolism of antioxidants caused by oxidative stress and may be responsiblefor significantly higher levels of lipid peroxidation products in smokers compared to nonsmokers (P < 0.05).
