Human serum carotenoid concentrations are related to physiologic and lifestyle factors.

摘要: We examined the concentrations of five carotenoids in serum and diet a population-based sample 400 individuals to determine what physiologic lifestyle factors were related carotenoid concentrations, how these relationships differed among carotenoids, if reflected differences intake. Lower α-carotene, β-carotene, β-cryptoxanthin, lutein + zeaxanthin generally associated with male gender, smoking, younger age, lower non-HDL cholesterol, greater ethanol consumption higher body mass index. Serum lycopene was not factors, but levels older age cholesterol. Only hydrocarbon (α- β-carotene lycopene) directly HDL The associations some (gender, intake) similar diet, indicating that may reflect influence on Consistent this notion, correlations between dietary did differ smokers nonsmokers. Other (HDL cholesterol index) intake, conditions affect absorption, storage, utilization associations. These behavioral correlates could explain or modify chronic diseases.
