In countries where people eat more oily fish, such as in the Mediterranean, Greenland and Japan, fewer people have heart disease compared to countries where people eat very little oily fish, such as the UK. There has been lots of research into Omega 3 fats and oily fish and how they can improve heart health. White fish and shell fish contain some omega 3s, but in smaller amounts. Oily fish such as sardines, salmon and mackerel are the best source of EPA and DHA. So, it’s good to eat foods that already contain them. Our bodies can make some EPA and DHA from ALA in the food we eat, but only a small amount. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).It’s mainly found in vegetable oils, nuts and seeds. Our bodies can’t make ALA, so we need to get it from the foods we eat. There are different types of omega 3s which are found in different foods. For a heart-healthy diet, it’s good to swap saturated fats for unsaturated fats. The other main type of fat is saturated fats, which raise your cholesterol levels. Omega 3 fats are a type of unsaturated fat – the type of fat that’s good for your cholesterol levels. They're especially good for heart health, and eating them could help to prevent heart attacks and strokes. References may also be found at the back of his books.Omega 3 fats are a group of fats we need to stay healthy. Sources for each video listed can be found by going to the video’s page and clicking on the Sources Cited tab. The information on this page has been compiled from Dr. In fact, the algae used for supplements are just grown in tanks and never even come in contact with the ocean. By getting EPA and DHA directly from the source at the bottom of the food chain, you don’t have to worry about pollutant contamination. Thankfully, you can get the benefits without the risks by getting long-chain omega-3s from algae instead, which is where the fish primarily get it from to begin with. This may help explain the studies that found adverse effects of fish consumption on cognitive function in adults and children. The concentration of dioxin-like pollutants in fish oil is so high that when taken as directed, salmon, herring, and tuna oils can cause the average person’s overall daily intake to exceed the tolerable limit of toxicity. Overall, the researchers found no protective benefit for overall mortality, heart disease mortality, sudden cardiac death, heart attack, or stroke.Īfter putting all the studies together, researchers concluded there was no longer justification for the use of omega-3s in everyday clinical practice.įish oil, even purified (“distilled”) fish oil, has been found to be contaminated with PCBs and other pollutants. These included studies not only on fish oil supplements, but also on the effects of advising people to eat more oily fish. But what does the science say?Ī systematic review and meta-analysis published in the Journal of the American Medical Association looked at all the best randomized clinical trials evaluating the effects of omega-3 fats on life span, cardiac death, sudden death, heart attack, and stroke. Why not supplement with omega-3 fish oil or just eat fish, though?įish oil pills have grown into a multibillion-dollar industry, thanks in part to the American Heart Association’s recommendation that individuals at high risk for heart disease should ask their physicians about omega-3 fish oil supplementation. Our body can then take that short-chain omega-3 and elongate it into the long-chain omega-3s EPA and DHA found in fish fat. That’s easy: My Daily Dozen recommendation for one tablespoon of ground flaxseeds takes care of that. According to two of the most credible nutrition authorities, the World Health Organization and the European Food Safety Authority, we should get at least a half a percent of our calories from the short-chain omega-3 ALA.
