Fats enriched with rapeseed oil (oleic and linolenic acids) appear to be equally effective in reducing plasma cholesterol and LDL cholesterol compared with butter/grapeseed oil, according to research designed to assess a more satisfactory effect on plasma lipoprotein profile of spreads based on dairy fat. There was a 7% fall in plasma cholesterol through replacing butter/grapeseed oil with rapeseed oil enriched fats. This is a significant result, given that it is widely assumed that a 1% fall in plasma cholesterol leads to a 2% fall in CDH risk. more...

The hypercholesterolemic effects of a dietary exchange between palmitic acid and oleic acid while linoleic acid is relatively lower in aged women with initially high serum cholesterol and low density lipoprotein cholesterol levels and with high intakes of dietary cholesterol were investigated. Participants were assigned to two consecutive 28-day periods in which they consumed sunflower oil diets rich in palmolein or oleic acid. Results showed that palmolein increased low density lipoprotein cholesterol levels and protected low density lipoproteins against peroxidation than did oleic acid. more...
