Abstract

Background: Epidemiological studies suggest a cardioprotective role for carotenoid-rich foods. Smokers have a high risk of cardiovascular disease and low dietary intake and plasma concentrations of carotenoids. The aim of this study was to determine the carotenoid response of smokers and nonsmokers to increased intake of 300–400 g of vegetables and its effect on LDL oxidation. Methods: After a depletion period of 8 days, 34 healthy females (18 nonsmokers, 16 smokers) were supplemented with β-carotene- and lutein-rich (green) and lycopene-rich (red) vegetable foods, each for 7 days. Results: Baseline concentrations (mean ± SD) of plasma β-carotene (0.203 ± 0.28 μmol/L vs 0.412 ± 0.34 μmol/L; P
