OBJECTIVES Previous studies suggest that dietary patterns and the extent of reliance upon traditional food vary among Inuit communities. Inuit traditional foods are an important source of nutrients such as highly unsaturated n-3 fatty acids (HUFA n-3), whose beneficial effects include protection against ischemic heart disease. Dietary transition is occurring with younger generations consuming l...

An increased dietary intake of n-3 highly unsaturated fatty acids (HUFA; >or=20 carbons, >or=3 carbon-carbon double bonds), particularly eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3), is associated with the decreased risk and incidence of several morbidities afflicting the elderly, including cognitive decline, dementia, rheumatoid arthritis, and macular degenerati...

It is well accepted that n-3 long-chain PUFA intake is positively associated with a range of health benefits. However, while benefits have been clearly shown, especially for CVD, the mechanisms for prevention/benefit are less understood. Analysis of plasma and erythrocyte phospholipids (PL) have been used to measure the status of the highly unsaturated fatty acids (HUFA), especially EPA (20 : 5...

European sea bass juveniles (14.4±0.1 g mean weight) were fed diets containing different levels of fish oil then of n-3 highly unsaturated fatty acids (n-3 HUFA) for 12 weeks. The fish performance as well as fatty acid (FA) composition of neutral and polar lipids from whole body after 7 and 12 weeks feeding were studied. The requirements of juvenile sea bass for n-3 highly unsaturated fatty aci...

The objective of this study was to evaluate the combined effects of thermal acclimation and n-3 highly unsaturated fatty acids (n-3 HUFA) content of the food source on the aerobic capacities of fish in a thermal changing environment. The model used was the golden grey mullet Liza aurata, a species of high ecological importance in temperate coastal areas. For four months, fish were exposed to tw...

Four replicated groups of sea bass (Dicentrarchus labrax) larvae were fed diets containing an extra-high level of highly unsaturated fatty acids (HUFA) (XH; 3.7 % EPA+DHA), a high level of HUFA (HH; 1.7 %), a low level of HUFA (LH; 0.7 %) or an extra-low level of HUFA (XLH; 0.5 %) from day 6 to day 45 (experiment 1; XH1, HH1, LH1, XLH1). After a subsequent 1-month period feeding a commercial di...

Cardiovascular disease (CVD) is a preventable disease, which combines two general processes: chronic vascular inflammation and acute thrombosis. Both are amplified with positive feedback signals by n-6 eicosanoids derived from food-based n-6 highly unsaturated fatty acids (n-6 HUFA). This amplification is lessened by competing actions of n-3 HUFA. Death results from fatal interactions of the va...

The effects of n-3 highly unsaturated fatty acids (n-3 HUFA) were studied on Beluga (Huso huso) fish larvae by feeding fish larvae with live food  enriched with 4 different oils (ICES 30/4, tuna eye oil, flaxseed oil and linseed oil) containing different levels of n-3 HUFA including 27.19, 20.33, 12.71 and 0.39 mg g-1 dry weight of oil, respectively. Fish larvae weighing 30.00±2.00 mg were rand...
