For instance, cigarette smokers have lower vitamin C (natural antioxidant) intakes and plasma vitamin C levels than nonsmokers. The incidence of cancer, heart disease, and cataracts is lower in populations that have high intakes of fruits or leafy green vegetables, all replete with vitamin C. Smokers who ate foods containing more than 200 mg vitamin C daily had serum vitamin C levels equivalent to those of nonsmokers who consumed 60 mg or more of the vitamin, according to a recent national survey.
