The American Heart Association (AHA) has issued an updated set of recommendations for people who have had a heart attack or who suffer from heart failure. <\/p>\n

According to the AHA, these heart patients should add a fish oil supplement to their diet to help prevent future heart-related events. Fish oil contains omega-3 fatty acids, which, when consumed by eating fatty fish, can cause blood vessel relaxation, reduced blood clotting, reduced inflammation and possibly stabilization of heart rhythm. <\/p>\n
But I disagree with the AHAs updated recommendation. Heres why. <\/p>\n
When it comes to the science behind fish oil or omega-3 supplements, the results are varied and oftentimes are conflicting. More research needs to be done before confirming that adding a fish oil supplement will help reduce a persons risk of future heart-related events. <\/p>\n
Only onelarge, randomized controlled clinical trial the gold standard in scientific research supports the concept that daily administration of 1 gram of an EPA\/DHA fish oil combination may benefit patients with coronary heart disease who have suffered a heart attack. Some scientists, however, take issue with the design and conduct of this and other studies that suggest a benefit from fish oil supplements in heart patients. <\/p>\n
There also arestudies withheart patients that have failed to confirm the benefits of the omega-3s. While some of these studies also have potential flaws that could explain their results, they do open the door to reasonable doubt. <\/p>\n
We also dont know for certain whether fish oilsupplementsare harmful again because wehave nostrong evidence to support or dispute that statement. <\/p>\n
Sowhenwe have that kind of a mixed picture, the right thing to do is toask for more research to resolve this conflict not tell people to take something because there mightbe somebenefit. <\/p>\n
Like all nutritional supplements, fish oil supplements are not regulated by the Food and Drug Administration (FDA), and do not go through the rigorousprocess of proving that they are safe and effective. Instead, supplements are regulated by Federal Trade Commission (FTC), which has no scientific expertise and does not even confirm whetherthe supplements actually contain the ingredients listed on their labels. <\/p>\n
When you take over-the-counter fish oil, you dont know what youre taking.The supplement may or may not contain the amount of fish oil that it is alleged to contain, and so we dont recommend that people take dietary supplements particularly when there is no solid evidence of a benefit. <\/p>\n
Fish oil has a mild blood-thinning effect and supplements should not be taken by patients who are taking blood thinners or who have propensity for bleeding. The supplements also can cause indigestion and fishy burps. <\/p>\n
Some fish oils may be contaminated with mercury. Research has shown that a large proportion of supplements perhaps as much as 40 percent contain contaminants, including lead, bacteria and pesticides. <\/p>\n
For people thinking about taking fish oil supplements, my advice is to talk with your doctorfirst. <\/p>\n
I personally would not recommend that you put anything in your body without very good evidence of benefit. If youwant to get more fish oil in yourdiet, you arebetter off simplyeating more fish. <\/p>\n
Oily fish belongsyour diet particularly as a replacement for red meats. Walk past the red meat counter at the grocery store every week and go instead to the seafood counter and get a nice piece of salmon. You reap a double benefit: a reduced intake of unhealthy saturated fats from red meat and ingestion of (potentially) heart-healthy fish oils. <\/p>\n
If you dont like fish, you can get plant-based omega-3 fatty acids from flaxseed, walnuts, green vegetables and some vegetable oils, including canola oil. Incorporating these foods into your diet is relatively easy: Sprinkle ground flaxseed on your cereal or yogurt, eat a handful of walnuts as a snack instead of a candy bar, or make a salad dressing with flaxseed oil. <\/p>\n
The evidence, however, that plant-based omega-3 fatty acids are heart-healthy is substantially weaker than the evidence in favor of fish-based omega-3s. For that reason, fish is the best choice. <\/p>\n
