An olive oil-rich diet results in higher

concentrations of LDL cholesterol and a higher number

of LDL subfraction particles than rapeseed oil and

sunflower oil diets.

ABSTRACT

We investigated the effect of olive oil, rapeseed oil,

and sunflower oil on blood lipids and lipoproteins

including number and lipid composition of lipoprotein

subclasses. Eighteen young, healthy men participated

in a double-blinded randomized cross-over study

(3-week intervention period) with 50 g of oil per 10

MJ incorporated into a constant diet. Plasma

cholesterol, triacylglycerol, apolipoprotein B, and

very low density lipoprotein (VLDL), intermediate

density lipoprotein (IDL), and low density lipoprotein

(LDL) cholesterol concentrations were 10;–20% higher

after consumption of the olive oil diet compared with

the rapeseed oil and sunflower oil diets [analysis of

variance (ANOVA), P < 0.05]. The size of IDL, VLDL,

and LDL subfractions did not differ between the diets,

whereas a significantly higher number (apolipoprotein

B concentration) and lipid content of the larger and

medium-sized LDL subfractions were observed after the

olive oil diet compared with the rapeseed oil and

sunflower oil diets (ANOVA, P < 0.05). Total HDL

cholesterol concentration did not differ

significantly, but HDL2a cholesterol was higher after

olive oil and rapeseed oil compared with sunflower oil

(ANOVA, P < 0.05).

In conclusion, rapeseed oil and sunflower oil had more

favorable effects on blood lipids and plasma

apolipoproteins as well as on the number and lipid

content of LDL subfractions compared with olive oil.

Some of the differences may be attributed to

differences in the squalene and phytosterol contents

of the oils. — Pedersen, A., M. W. Baumstark, P.

oil-rich diet results in higher concentrations of LDL
