The literature on risk factors for cardiometabolic diseases showed that lutein might be beneficial for atherosclerosis and inflammatory markers , but there were inconsistent associations with blood pressure , adiposity , insulin resistance , and blood lipids .
CONCLUSIONS Our findings suggest that higher dietary intake and higher blood concentrations of lutein are generally associated with better cardiometabolic health .
BACKGROUND The antioxidant lutein is suggested as being beneficial to cardiometabolic health because of its protective effect against oxidative stress , but evidence has not systematic ally been evaluated .
OBJECTIVE We aim ed to evaluate systematic ally the effects of lutein ( intake or concentrations ) on cardiometabolic outcomes in different life stages .
High plasma levels of alpha- and beta-carotene are associated with a lower risk of atherosclerosis: results from the Bruneck study.
BACKGROUND AND PURPOSE A large number of studies have contributed to the hypothesis that carotenoids , vitamins A and E are protective against atherosclerosis by acting as antioxidants . The aim of this study was to assess the relationship between plasma levels of carotenoids ( alpha- and beta- carotene , lutein , lycopene , zeaxanthin , beta-cryptoxanthin ) ,  vitamins A and E  , and atherosclerosis in the carotid and femoral arteries . METHODS This prospect i ve and cross sectional study involved a r and omly selected population sample of 392 men and women aged 45 - 65 years .  Carotid and femoral artery atherosclerosis was assessed by high-resolution duplex ultrasound . RESULTS alpha- and beta- carotene plasma levels were inversely associated with the prevalence of atherosclerosis in the carotid and femoral arteries ( P=0.004 ) and with the 5-year incidence of atherosclerotic lesions in the carotid arteries ( P=0.04 ) . These findings were obtained after adjustment for other cardiovascular risk factors ( sex , age , LDL ( low density lipoproteins ) , ferritin , systolic blood pressure , smoking , categories of alcohol consumption , social status , C-reactive protein ) . Atherosclerosis risk gradually decreased with increasing plasma alpha- and beta-carotene concentrations ( P=0.004 ) . No associations were found between vitamin A and E plasma levels and atherosclerosis . CONCLUSIONS This study provides further epidemiological evidence of a protective role of high alpha- and beta- carotene in early atherogenesis
