[Effect of the ingestion of thermically treated fat on blood lipids and blood lipoproteins in the rat].
The effect on rats fed on a diet with 15% solid frying fat (diet B) is compared to the effect of a diet with 15% of the same fat but in the raw state (diet A). After 10 weeks being fed on these diets serum triglycerides, phospholipids, total cholesterol, free cholesterol, esterified cholesterol, high density lipoprotein-cholesterol and free fatty acid levels were checked. Percentage of very low density lipoproteins (VLDL), low density lipoproteins (LDL) and high density lipoproteins as well as the composition of these lipoproteins was determined in parallel. Rats fed on diet B showed a significant increase in phospholipids and a significant decrease in VLDL when compared to those fed on diet A. Phospholipids on LDL decreased significantly in diet B fed rats. The data obtained seem to indicate that the hypercholesterolemic tendency induced by frying fat is neutralized by a decrease in VLDL levels.
