BACKGROUND The traditional diet of Inuit people comprises large amounts of fish and marine mammals that are rich in omega-3 polyunsaturated fatty acids (PUFAs). Results from in vitro studies, laboratory animal experiments and population studies suggest that omega-3 PUFA intake and a high omega-3/omega-6 ratio exert a positive effect on bone health. OBJECTIVE This longitudinal study was conduc...

Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferre...

Intake of fish or omega-3 fatty acids may decrease risk of total and coronary heart disease death, but evidence from low-risk populations is less convincing. The authors assessed intake by using a food frequency questionnaire at baseline in a cohort of Iowa women aged 55-69 years. Among women initially free of heart disease and cancer (4,653 deaths over 442,965 person-years), there was an inver...

Dietary polyunsaturated fatty acids (PUFAs), which are abundant in marine fish oils, have recently received global attention for their prominent anti-obesogenic effects. Among PUFAs, eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3), which are n-3 long-chain PUFAs widely referred to as omega-3 oils, were reported to prevent the development of obesity in rodents and hu...

Omega-3 fatty acids from marine and plant sources provide a wide range of benefits in several human health conditions. In vivo studies indicate that omega-3 fatty acids influence the course of several human diseases, including those that involve abnormal immune function, mental disorders, and genetic abnormalities in lipid metabolism. Omega-3 fatty acids are taken up by virtually all body cells...

Learning Objectives At the conclusion of this course, the student will be able to: 1. Identify the different types of fatty acids. 2. Distinguish between marine and plant sources of omega-3 fatty acids. 3. Explain the health benefits of omega-3 fatty acids. 4. State the recommendations for consuming omega-3 fatty acids. 5. Discuss key studies demonstrating the effects of omega-3 fatty acids on ...

Cardiovascular diseases and cancers are leading causes of morbidity and mortality. Reducing dietary saturated fat and replacing it with polyunsaturated fat is still the main dietary strategy to prevent cardiovascular diseases, although major flaws have been reported in the analyses supporting this approach. Recent studies introducing the concept of myocardial preconditioning have opened new ave...

Marine omega-3 rich oils are used by more than a third of American adults for a wide range of purported benefits including prevention of cardiovascular disease. These oils are highly prone to oxidation to lipid peroxides and other secondary oxidation products. Oxidized oils may have altered biological activity making them ineffective or harmful, though there is also evidence that some beneficia...
