Animal fat, are often associated with diet-related health problems such as obesity, diabetes, cardiovascular disease (CVD), and tumours. However, ruminant's fat can be modified according to animal diet, and fat from light lambs (namely lambs fed exclusively mother's milk) is particularly rich in conjugated linoleic acid (CLA) and ✓-linolenic acid (ALA)(1). We have shown that in hypercholesteraemic subjects food enriched with CLA and ALA is able to significantly increase plasma n-3 HUFA score(2), a biomarker of n-3 fatty acid in tissue. This is calculated as the percentage of n-3 highly unsaturated fatty acid (HUFA ≥ 20 carbons and ≥ 3 double bonds) in the total PUFA pool mainly incorporated into phospholipids, and potentially precursors of biological active eicosanoids and docosahexaenoids(3). Therefore, an enhanced n-3 HUFA score reflects an increase of n-3/n-6 HUFA ratio in tissues,...
