Fish oil is hailed for its plentiful health benefits. But new research suggests that the long-term consumption of fish oil or sunflower oil may increase the risk of fatty liver disease later in life. By studying rats, researchers found that lifelong intake of sunflower oil or fish oil led to changes in the liver that make the organ vulnerable to non-alcoholic steatohepatitis (NASH). NASH is a more serious form of non-alcoholic fatty liver disease (NAFLD). Study co-author José Luis Quiles, a professor of physiology working at the University of Granada in Spain, and colleagues recently reported their findings in The Journal of Nutritional Biochemistry. It is estimated that around 20 percent of people in the United States who have NAFLD also have NASH, and the condition becomes more common with age. NASH is characterized by a buildup of fat in the liver — which is not caused by alcohol consumption — inflammation, and liver cell damage. The liver damage that occurs in NASH … [Read more...] about Fish oil may not be as healthful as you think, study finds

I want to start taking over-the-counter fish oil supplements to boost my heart health. But I don't know which kind to choose.The active ingredient in fish oil capsules is omega-3 fatty acids, and different brands contain varying amounts--typically, about 300 mg per capsule.

You’re probably tired of reading about omega-3 fatty acids, which mounds of medical research have linked to everything from mellower arthritis pain to stronger DNA. In most cases, the health benefits revolve around omega-3’s ability to quell inflammation. But do fish oil supplements match the anti-inflammation benefits of fish—nature’s omega-3 champ? Maybe not, suggests research published in the journal Metabolism. An Australian study team split 28 overweight people into two groups. While members of one group forked down roughly 20 ounces of fish per week for 1 month, the others swallowed daily supplements containing nearly 2,000 mgs of omega-3. Before and after the study period, the researchers measured each person’s levels of a hormone called adiponectin, which past studies have tied to lower inflammation. Here’s what they discovered: While total adiponectin levels jumped roughly 12 percent among the fish eaters, the supplement group experienced … [Read more...] about Fish or Fish Oil Supplements

RODALE NEWS, EMMAUS, PA—Some of the largest fish oil supplement producers, and the stores that carry them, are selling supplements contaminated with a class of now-banned industrial chemicals known as polychlorinated biphenyl compounds, or PCBs, charges a lawsuit filed earlier this month by the Manteel Justice Foundation and two other citizens. "Consumers who want the health benefits of fish oil shouldn't have to take the health risks of an extremely toxic man-made chemical," David Roe, one of the attorneys for the plaintiffs, said in a press release.THE DETAILS: The lawsuit names eight makers and sellers of fish oil, shark oil, fish liver oil, and shark liver oil supplements that the plaintiffs say are contaminated above the "safe harbor" limits set for human PCB consumption under California's Proposition 65, a law that requires consumers be warned about such harmful exposures. So far, defendants named in the lawsuit include CVS Pharmacy Inc.; General Nutrition Corp. (GNC); Now … [Read more...] about Fish Oil Lawsuit Raises Safety Questions

The health benefits of omega-3 fatty acids are well-known and range from lowering the risk of heart disease to protecting cognitive function. New research suggests that supplements of the unsaturated fat may have an additional benefit: they may lower the risk of childhood asthma. Omega-3 fatty acids are one of the two major classes of polyunsaturated fat. They can be found in certain foods like flaxseed and fish, as well as in dietary supplements such as fish oil. So far, research has indicated that omega-3 fatty acids - when consumed directly from food - have a variety of health benefits. A moderate consumption of seafood has been shown to reduce the risk of cardiovascular disease and has also been associated with a reduced risk of cognitive decline, Alzheimer's disease, and dementia. A weekly consumption of at least 8 ounces of seafood by pregnant women also seems to improve health outcomes in their infants. A new study - carried out by the Copenhagen Prospective Studies on … [Read more...] about Fish oil during pregnancy may reduce risk of childhood asthma
One of the best reasons for taking fish oil supplements, a potent source for omega-3 fatty acids, is their supposed benefits for staving off dementia. But not so fast—a new study suggests that fish oil might not be so great for your brain after all. Could it be true? Take a look at the facts. The new research, published in The Cochrane Library, involved a review of a collection of other studies that analyzed the effects of taking omega-3 supplements on cognitive function—the brain’s ability to process thoughts, including making and retrieving memories—over time. Combing through nearly 2,000 existing studies, the researchers looked for studies that compared cognitive function in healthy people without dementia taking omega-3 supplements to those taking a placebo for at least six months. The Best Vitamins for Women Narrowing down their selections to just three studies, involving a total of 3,536 people, the researchers found that those who took … [Read more...] about Can Fish Oil Make You Smarter?
