  • Fish and Omega-3: Questions and Answers for Health Professionals
    Fish and omega-3: Questions and answers for health professionals The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 milligrams (mg) of marine-sourced omega-3s (EPA, DHA) per day. The Heart Foundation also recommends that all Australians should aim for 1 gram of plant-sourced omega-3 (ALA) each day. The Heart Foundation based these recommendations on a scientific review of evidence. For more information, you can access the full text article in the journal Heart, Lung and Circulation, available at www.heartlungcirc.org/article/S1443-9506(15)00167-5/abstract Marine-sourced and plant-sourced omega-3s should be included as part of a heart-healthy diet that includes vegetables and legumes, fruit, wholegrain cereals, lean meats and their alternatives, fish, nuts and seeds, reduced fat milk, cheese and yoghurt, healthier fats and oils, and limits salt. Key messages Fish The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 mg of marine-sourced omega-3s (EPA, DHA) per day. Because the body cannot produce omega-3s they need to be sourced through diet. The scientific evidence supports fish as the best dietary source of omega-3s and found higher fish intake was consistently associated with lower rates of heart disease (heart failure and sudden cardiac death) and stroke. Fish with the highest levels of omega-3 include salmon, blue-eye trevalla, blue mackerel, herring, canned sardines, canned salmon and some varieties of canned tuna.

The ease with which the fatty acid , on composition of fish body oils can be manipulated by altering the fatty acid composition of their feeds 28 Sep 2021 at 10:11:22 is emphasized and the dietary requirements of marine and freshwater fish for 12-3 and n-6 polyunsaturates considered. Farming fish on diets containing principally fish meal and fish oil, as used in salmon production in Scotland, generates a high quality product with levels of long-chain n-3 polyunsaturates equalling or exceeding those of wild fish. Farming fish on high quality marine oils rich in docosahexaenoic and eicosapentaenoic acids is an efficient means of delivering these essential nutrients in human diets and also efficiently exploiting a strictly limited marine bioresource.

So, although canned tuna is a healthy choice for most people, it does not count as oily fish. ** Albacore, Long-Fin Tuna is white in colour. As a result, it is often marketed as 'white meat tuna' or 'chicken of the sea', but it is still an oily fish.

  • Prescription: Sustainable Seafood
    Why health professionals should care about sustainable fisheries PRESCRIPTION: SUSTAINABLE SEAFOOD Health benefits of seafood consumption A growing body of scientific literature demonstrates that consuming even modest amounts of fish helps protect against heart disease and stroke, and may have important benefits for pre- and post-natal cognitive development. The federal government1 and American Heart Association2 both note that eating two servings of fatty fish per week may reduce the risk of coronary heart disease in healthy people and the risk of mor- tality from cardiovascular disease in people who have already experienced a cardiac event. At present, Amer- icans fall short of these consumption levels, averaging only five ounces of fish per week. U.S. fish oil capsule sales have tripled in recent years. By contrast, terrestrial sources of omega-3s contain primarily the shorter chain alpha-linolenic acid (ALA), which is not as beneficial. Some food products are enriched with omega-3s— generally plant-derived ALA or fish-derived DHA/EPA.4 At least one company produces DHA directly from marine algae; their product is used to enrich many infant formulas and a few other products.5 However, commercial use of algal DHA in foods is not wide- spread to date. In short, consuming fish or fish oil (or products Salmon is popular for its high omega-3 content. enriched with fish oil) is currently the only way to add substantial quantities of key heart-healthy omega-3s Omega-3 fatty acids to the diets of most Americans. Cardiovascular benefits are greatest from consuming fish high in long-chain omega-3 fatty acids, namely docosahexaenoic acid (DHA) and eicosapentaenoic Wild fisheries acid (EPA).3 The highest levels of these omega-3s occur Sadly, even as the health benefits of eating fish are be- in small oily fish such as mackerel and herring, and coming increasingly clear, the ocean’s ability to provide larger predatory fish such as salmon and some tuna.

    SOUTHERN REGIONAL SRAC Publication No. 7300 AQUACULTURE CENTER October 2012 VI PR Nutritional Benefits of Seafood Elizabeth Reames1 Seafood is a healthful choice for people of all ages— growing children, pregnant women, active adults, and the elderly. Seafood is an excellent source of lean, high quality, easily digested protein. A 3.5-ounce serving of seafood provides almost half of an adult’s daily protein needs for only 100 to 200 calories. Seafood is low in satu- rated fat and sodium and is a rich source of many essen- tial vitamins and minerals. Seafood also is one of the few foods that contain long-chain omega-3 fatty acids, which have many beneficial health effects and are essential for the development of the nervous system and retina. Seafood includes fish such as catfish, salmon, tuna, trout and tilapia, and shellfish such as shrimp, crab, clams and oysters. Most of the seafood purchased in the United States comes from marine waters and from aqua- culture (farm-raised fish). Boiled crawfish platter. (photo provided by W.
