Conclusion The Nordic dietary pattern  improves blood pressure and also some of blood lipid markers and it should be considered as a healthy dietary pattern
Background and aims The Nordic diet ( ND ) , is supposed to be associated with a reduced cardiovascular risk ; however , clinical trials have led to inconsistent results regarding the effect of this diet on cardio-metabolic markers .
Using systematic review and meta- analysis of r and omized controlled trials ( RCTs ) , this study aim ed to investigate the effect of the ND on circulating levels of total , low-density lipoprotein ( LDL ) , and high-density lipoprotein ( HDL ) cholesterol , and triglyceride ( TG ) , as well as blood pressure in human adults .
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.
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 r and omized 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 HDL(2a ) 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
