CONCLUSIONS Palm oil consumption results in higher LDL cholesterol than do vegetable oils low in saturated fat and higher HDL cholesterol than do trans fat-containing oils in humans .
The effects of palm oil on blood lipids are as expected on the basis of its high saturated fat content , which supports the reduction in palm oil use by replacement with vegetable oils low in saturated and trans fat .
BACKGROUND Palm oil contains a high amount of saturated fat compared with most other vegetable oils , but studies have reported inconsistent effects of palm oil on blood lipids .
OBJECTIVE We systematic ally review ed the effect of palm oil consumption on blood lipids compared with other cooking oils using data from clinical trials .
Diets high in palmitic acid (16:0), lauric and myristic acids (12:0 + 14:0), or oleic acid (18:1) do not alter postprandial or fasting plasma homocysteine and inflammatory markers in healthy Malaysian adults.
BACKGROUND Dietary fat type is known to modulate the plasma lipid profile , but its effects on plasma homocysteine and inflammatory markers are unclear . OBJECTIVE We investigated the effects of high-protein Malaysian diets prepared with palm olein , coconut oil ( CO ) , or virgin olive oil on plasma homocysteine and selected markers of inflammation and cardiovascular disease ( CVD ) in healthy adults . DESIGN A r and omized-crossover intervention with 3 dietary sequences of 5 wk each was conducted in 45 healthy subjects . The 3 test fats , namely palmitic acid (16:0)-rich palm olein ( PO ) , lauric and myristic acid ( 12:0 + 14:0)-rich CO , and oleic acid (18:1)-rich virgin olive oil ( OO ) , were incorporated at two-thirds of 30 % fat calories into high-protein Malaysian diets . RESULTS No significant differences were observed in the effects of the 3 diets on plasma total homocysteine ( tHcy ) and the inflammatory markers TNF-α , IL-1β , IL-6 , and IL-8 , high-sensitivity C-reactive protein , and interferon-γ . Diets prepared with PO and OO had comparable nonhypercholesterolemic effects ; the postpr and ial total cholesterol for both diets and all fasting lipid indexes for the OO diet were significantly lower ( P < 0.05 ) than for the CO diet . Unlike the PO and OO diets , the CO diet was shown to decrease postpr and ial lipoprotein(a ) . CONCLUSION Diets that were rich in saturated fatty acids prepared with either PO or CO , and an OO diet that was high in oleic acid , did not alter postpr and ial or fasting plasma concentrations of tHcy and selected inflammatory markers .
