Current evidence on the effects of palm oil consumption on biomarkers of glucose metabolism is poor and limited to only healthy participants .
We conclude that little or no additional benefit will be obtained by replacing palm oil with other oils rich in mono or polyunsaturated fatty acids for changes in glucose metabolism
INTRODUCTION Vegetable oil is an important source of fatty acids , and as palm oil being the highest consumed vegetable oil in many countries , its high saturated fatty acid content has led many concerns on cardiometabolic health .
Dietary fatty acids has also been linked to affect glucose metabolism and insulin sensitivity .
This systematic review is aim ed at critically evaluating the available evidence on the association of palm oil with the biomarkers of glucose metabolism as compared to other vegetable oils .
Comparing effects of soybean oil- and palm olein-based mayonnaise consumption on the plasma lipid and lipoprotein profiles in human subjects: a double-blind randomized controlled trial with cross-over design
Background Mayonnaise is used widely in contemporary human diet with widespread use as a salad dressing or spread on breads . Vegetable oils used in its formulation may be a rich source of ω-6 PUFAs and the higher-PUFA content of mayonnaise may be beneficial in mediating a hypocholesterolemic effect . This study , therefore , evaluated the functionality of mayonnaise on cardiometabolic risk within a regular human consumption scenario . Methods Subjects underwent a r and omized double-blind crossover trial , consuming diets supplemented with 20 g/day of either soybean oil-based mayonnaise ( SB-mayo ) or palm olein-based mayonnaise ( PO-mayo ) for 4 weeks each with a 2-week wash-out period . The magnitude of changes for metabolic outcomes between dietary treatments was compared with PO-mayo serving as the control . The data was analyzed by ANCOVA using the GLM model . Analysis was adjusted for weight changes . Results Treatments result ed in significant reductions in TC ( diff = −0.25 mmol/L ; P = 0.001 ) , LDL-C ( diff = −0.17 mmol/L ; P = 0.016 ) and HDL-C ( diff = −0.12 mmol/L ; P < 0.001 ) in SB-mayo compared to PO-mayo without affecting LDL-C : HDL-C ratio ( P > 0.05 ) . Lipoprotein particle change was significant with large LDL particles increasing after PO-mayo ( diff = + 63.2 nmol/L ; P = 0.007 ) compared to SB-mayo but small LDL particles remained unaffected . Plasma glucose , apolipoproteins and oxidative stress markers remained unchanged . Conclusions Daily use with 20 g of linoleic acid-rich SB-mayo elicited reductions in TC and LDL-C concentrations without significantly changing LDL-C : HDL-C ratio or small LDL particle distributions compared to the PO-mayo diet . Trial registration This clinical trial was retrospectively registered with the National Medical Research Register , National Institute of Health , Ministry of Health Malaysia , ( NMRR-15 - 40 - 24035 ; registered on 29/01/2015 ; https://www.nmrr.gov.my/fwbPage.jsp?fwbPageId= Research ISRForm&fwbAction = Up date & fwbStep=10&pk . research ID=24035&fwbVMenu=3&fwb Research Action = Up date ) . Ethical approval was obtained from the National University of Malaysia ’s Medical Ethics Committee ( UKM 1.5.3.5/244/SPP/NN-054-2011 , approved on 25/05/2011 )
