Pr. Chen et Ce. Tsai, VARIOUS HIGH MONOUNSATURATED EDIBLE OILS MIGHT AFFECT PLASMA-LIPIDS DIFFERENTLY IN MAN, Nutrition research, 15(5), 1995, pp. 615-621
This study investigated the effects of three high monounsaturated edib
le oils with different fatty acid compositions on plasma lipid metabol
ism in man. Ten healthy young men were engaged for this study, and rec
eived four various experimental meals respectively prepared with diffe
rent cooking oils, i.e. olive oil, liquid lard, rice bran oil or soybe
an oil (control). These oils supplied 32.7% of the daily total calorie
s for a period of 18 days, and had normal diet at each interval of two
experimental diets for at least 18 days in order to return to the pre
vious normal physiological condition. Results showed that the reducing
effects of the rice bran oil and soybean oil diets on percent changes
of the plasma total lipids, total cholesterol and LDL-C were signific
antly larger (P<0.05) than the ones of the olive oil diet. The data al
so demonstrated that ingestion of soybean oil might have lower HDL-C t
han of olive oil. The results indicated that the saturation, P/S and P
+M/S ratio of various edible oils had no consistency with the response
s of plasma lipids. Therefore, it might suggest that effects of certai
n fatty acids in an edible oil may be stronger than its saturation on
lipid metabolism.
