DIETARY FATTY-ACIDS - THEIR IMPACT ON SER UM-LIPIDS, LIPOPROTEINS ANDATHEROSCLEROSIS

There are important new data concerning the influence of dietary fats on serum cholesterol and lipoproteins. Earlier results of US-American authors, expressed in the regression equations of Keys, of Hegsted and their collaborators, have been amply confirmed even by authors who in terpret their results differently. More recent results concerning tran s-fatty acids, stearic acid, n-3-fatty acids which are not considered in the formulae of Keys and Hegsted could have been predicted from mod ern biochemistry of fatty acids. There are new results describing the influence of chain length of fatty acids on serum lipids. Recent studi es center around the influence of fatty acids on lipoproteins. It appe ars that n-6-polyenoic fatty acids lower LDL but n-3-polyenoic fatty a cids lower VLDL. Within the range of foods, commercially available in central Europe, fatty acids do not influence HDL.
