Randomized Controlled Trial
Determining the mechanisms of dietary turnip rapeseed oil on cholesterol metabolism in men with metabolic syndrome.
We have earlier reported the reduction of total cholesterol, low-density lipoprotein (LDL) cholesterol and oxidized LDL caused by short-term modification of diet with cold-pressed turnip rapeseed oil (CPTRO) instead of butter. The aim of this supplementary study was to determine whether the beneficial effects resulted from altered cholesterol metabolism during the intervention. Thirty-seven men with metabolic syndrome (MetS) completed an open, randomized and balanced crossover study. ⋯ Serum PCSK9 concentration did not differ between CPTRO and butter periods. The reduction in serum cholesterol by 7.2% after consumption of rapeseed oil could not be explained by changes in cholesterol absorption, synthesis or PCSK9 metabolism in MetS.
