Zusammenfassung:To determine the effect of nutritional agents on lipid peroxidation, 10 smokers were given 6 mg beta carotene, 200 IU vitamin E, and 250 mg vitamin C 4 times daily for 3 weeks. Lipid peroxidation was assessed by measuring baseline and postsupplementation levels of exhaled ethane. There was a 29% decrease in mean (±SD) exhaled ethane (4.06±1.49 vs 2.90±1.29 pmol-kg−1 min−1), with individual levels decreasing in 8 of the 10 smokers (p
