Feeding a fish oil-rich diet may exert hypocholesterolemic effects. The aim of this work was to examine the effects of a life-long administration of a PUFA-enriched diet and of a PUFA-deficient diet in male Sprague–Dawley rats on the age-associated increases in plasma cholesterol and triglycerides. Diet had small effects on body-weight, and had dramatic effects on liver phospholipids-fatty acids. Surprisingly, both diets counteracted the age-associated changes in plasma cholesterol and triglycerides similarly and benefits were already visible in adult rats. publisher: Elsevier date: 2008 type: Article type: PeerReviewed identifier: Straniero, Sara and Cavallini, Gabriella and Donati, Alessio and Metelli, Maria Rita and Tamburini, Ilaria and Pietrini, Pietro and Bergamini, Ettore Deficiency and supplementation of {PUFA} in the diet have similar effects on the age-associated changes in rat-plasma cholesterol levels.
