Effects of edible oils on blood and arterial lipids in rats after one year's balanced normolipidic diet.
Male Sprague-Dawley rats were fed during one year with diets containing 12% of one of the following fats: butter, sunflower oil, rapeseed oil, soybean oil, hydrogenated soybean oil, palm oil, canbra oil and arachid oil. Total serum cholesterol was lower in the arachid, suflower and butter groups and higher in the palm and hydrogenated soybean groups (p less than 0.01); serum cholesterol esters were lower in the arachid, sunflower and soybean groups, but higher in the palm and hydrogenated soybean groups ( p less than 0.01). Serum triglycerides were lower in the sunflower and arachid groups and higher in the butter and palm groups (p less than 0.01). There was a positive, significant correlation between serum cholesterol and phospholipids in the various groups. In aortas, free cholesterol levels were the same in different groups, but cholesterol ester levels increased in the following order: canbra, butter, arachid, palm, sunflower, rapeseed, hydrogenated soybean and soybean red groups (p less than 0.01). There was a significant correlation between aorta cholesterol esters and the ratio 18:0 + 18:1 of the dietary fat (r = 0.69; p less than 0.001).
