Comparison of PO diets with diets rich in stearic acid , monounsaturated fatty acids ( MUFAs ) , and polyunsaturated fatty acids ( PUFAs ) showed significantly higher TC , LDL cholesterol , apolipoprotein B , HDL cholesterol , and apolipoprotein A-I , whereas most of the same biomarkers were significantly lower when compared with diets rich in myristic/lauric acid .
Comparison of PO-rich diets with diets rich in trans fatty acids showed significantly higher concentrations of HDL cholesterol and apolipoprotein A-I and significantly lower apolipoprotein B , triacylglycerols , and TC/HDL cholesterol .
Stratified and meta-regression analyses showed that the higher concentrations of TC and LDL cholesterol , when PO was substituted for MUFAs and PUFAs , were not significant in young people and in subjects with diets with a lower percentage of energy from fat .
Both favorable and unfavorable changes in CHD/CVD risk markers occurred when PO was substituted for the primary dietary fats , whereas only favorable changes occurred when PO was substituted for trans fatty acids .
BACKGROUND Palm oil ( PO ) may be an unhealthy fat because of its high saturated fatty acid content .
OBJECTIVE The objective was to assess the effect of substituting PO for other primary dietary fats on blood lipid-related markers of coronary heart disease ( CHD ) and cardiovascular disease ( CVD ) .
Effects of red palm oil on serum lipids and plasma carotenoids level in Chinese male adults.
OBJECTIVE Effects of red palm oil on major plasma carotenoids , tocopherol , retinol and serum lipids were evaluated when used in Chinese diet . METHODS Red palm oil group ( RPO ) composed of 20 male subjects(aged 18 - 32 ) and soybean oil group ( SBO ) composed of 22 male subjects ( aged 18 - 32 ) . Dietary fat provided about 28 % of total calories , and the test oil accounted for about 60 % of total dietary fat . In the 3 weeks of pretest period , diets were prepared with soybean oil , and then in the next 6 weeks subjects in each group consumed the diet prepared by test oil . RESULTS Plasma alpha-carotene , beta-carotene and lycopene concentration of RPO group significantly increased at the time of interim ( 21 days ) and of the end ( 42 days ) ( P < 0.05 ) , and alpha-tocopherol concentration significantly increased at the time of the end ( 42 days ) in this study . Though Chinese plasma retinol level was relatively low when compared with that of Westerners , red palm oil diet showed no significant effect on adult Chinese plasma retinol level . Serum concentration of total cholesterol , triglyceride , high density lipoprotein cholesterol , apolipoprotein AI and apolipoprotein B of all subjects showed no significant changes in RPO group during the study . CONCLUSIONS The data in our study suggest that red palm oil is a good source of carotenoids and vitamin E when used in Chinese diet preparation , and it can significantly increase plasma concentration of alpha-carotene , beta-carotene , lycopene and alpha-tocopherol
