Q: I keep hearing that omega-3 fats in fish oil are more heart-healthy than ones from other sources. Why is that?The omega-3 fatty acids found in fish and marine mammals (EPA and DHA, mostly) consist of long molecular chains, which are more efficiently absorbed and used in the body than the shorter-chain omega-3s (such as ALA) found in walnuts, flax, hemp seed, and wild greens. Although the exact mechanism is still unknown, the longer-chain omega-3s have been shown to reduce arterial plaque, promote blood vessel dilation, lower triglyceride levels, and protect against heart disease. The FDA has even approved a prescription-only fish oil brand, called Lovaza, to lower triglycerides. If you're a vegetarian, you can benefit from flaxseed or hemp seed oil, though neither seems to lower triglycerides as well as longer-chain fatty acids.

RODALE NEWS, EMMAUS, PA—A new government study finds that certain types of omega-3s found in fish can cut your risk of colon cancer by nearly 40 percent. The study, published in last month's issue of the American Journal of Epidemiology, found that DHA and EPA, found primarily in fish oil, had a greater impact on lowering colorectal cancer risk than the omega-3s found in plants or other fatty acids common in healthy foods like olive oil and other vegetable oils.THE DETAILS: A total of 1,872 adults participated in the study, 929 of whom had already been diagnosed with some form of colorectal cancer and 943 who were healthy. Researchers interviewed all the participants about their medical histories and their physical activity levels and then asked them to fill out dietary recall questionnaires. Nutrient intake was calculated using information from the National Cancer Institute, and the researchers paid particular attention to intake of 19 different omega-6 and omega-3 fatty acids. … [Read more...] about Omega-3s from Fish Oil Found to Lower Colon Cancer Risk
Cod liver oil is traditionally believed to be healthful for people's bones. But could cod liver oil and other fish oils play a role in the treatment of arthritis? Arthritis is a common condition that affects 1 in every 5 adults in the United States and is a leading cause of disability. Arthritis affects people's joints, either through inflammation or through cartilage degeneration. This article explores whether fish oil could be beneficial in the treatment of arthritis and how to use it. There are two common types of arthritis, both of which can cause joint pain, stiffness, and mobility problems. These are: Rheumatoid arthritis (RA): An inflammatory joint disease caused by a problem in the immune system. Osteoarthritis (OA): A degenerative condition that affects joint cartilage and bones. Cod liver oil and fish oil contain high levels of two types of omega-3 fatty acids: DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). Researchers have found that EPA and DHA both reduce … [Read more...] about Benefits of fish oil for arthritis
For instance, alpha-linolenic acid is found in plant-based sources such as walnuts and flaxseed. On the other hand, many of the benefits of omega-3 fatty acids come from fatty fish such as salmon, rainbow trout, mackerel, herring, sardines, and tuna. Fish oil is particular is good source of omega-3 fatty acids (1). The benefits of omega-3 fish oil mostly come from two types of omega-3s: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). What happens when you don’t get enough omega-3s in your diet? Unfortunately, this is a problem for many Americans. In the U.S., omega-3 fatty acid deficiencies are linked to the top causes of death, mostly because of an imbalance between omega-3 and omega-6 fatty acids. Omega-6 is still an essential fatty acid, but when high amounts of omega-6 are consumed with low amounts of omega-3, inflammation and chronic illness can result. The average American consumes omega-6 to omega-3 fatty acids in a 20:1 ratio, because omega-6 is a common … [Read more...] about 9 Omega-3 Fish Oil Benefits (and 5 Side Effects)
1) from the diet, and many Americans fail to get the right balance of omega-3s and omega-6s. The Standard American Diet is a key factor in this imbalance because the average American consumes too many foods high in omega-6s such as fried foods, fast foods, meats, dairy, and vegetable oils, and not enough omega-3s. What type of omega-3 fatty acids should be a part of the diet? Among the main sources of omega-3s are flaxseeds and flaxseed oil, and fish and fish oil. When it comes to flaxseed oil vs. fish oil, which omega-3 source is best? Flaxseed oil and fish oil contain different types of omega-3 fatty acids, so they each have different effects on the body. Fish and fish oil contain omega-3s known as docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). On the other hand, flaxseed and flaxseed oil contain alpha-linolenic acid (ALA) (2). The human body does not make EPA, DHA, or ALA, so we have to get these nutrients from our diets. There are pros and cons to taking both … [Read more...] about Flaxseed Oil vs. Fish Oil: Which is the Best Omega-3 Source?

You’re unlikely to see krill or krill oil on a restaurant menu near you, although it’s eaten in Japan under the name Okiami. Krill is a small, nondescript crustacean, so what are the uses of krill oil? If researchers are correct, krill provides oil that can assist in treating everything from arthritis to erectile dysfunction, as well as making your eyes and brain work better. Krill’s the catch-all name for 85 or so species and has probably the largest biomass on earth: hundreds of millions of tons. In other words, all the krill in the sea weigh more than any other species. That’s astonishing when you consider, for example, all the cows and sheep in the world. If you’ve seen the movie Happy Feet Two, the krill are Will and Bill, the shrimp-like critters bickering and biting seals’ butts in their search for enlightenment. Movie buffs will recognise the voices of Matt Damon and Brad Pitt, but in the real world, these invertebrate crustaceans have an … [Read more...] about Krill Oil: Stop That “Krilling” Pain From Your Arthritis
So what’s in your fish oil? Is it made with Chinese fish oil? And why does the bottle not say ‘Made in China’ if the fish oil pills were made in China? It’s easy for supplement companies to find loopholes in labeling rules. And most do. In all my years in the dietary supplement industry, I have never heard of any supplement company getting in trouble for country-of-origin issues. 80 year old regulations The laws governing country-of-origin declaration is 80 years old. It was put in place when Herbert Hoover was in the White House and when China was a poor farming society. Things have changed. Regardless, the law says where ever the products underwent ‘substantial transformation’ is the country of origin. That’s a loophole big enough to drive a Hummer through. Theoretically, if the pills inside the bottle cost $2, and the packaging costs $3, then wherever the bottle was packaged is where there was a ‘substantial … [Read more...] about Is Your Fish Oil Made in China?
Millions of Americans and Canadians take fish oil supplements on a daily basis, in hopes of maintaining good cardiovascular health.

LabDoor is a testing company that examined the 30 top-selling brands of fish oil supplements in the U.S. Researchers assessed the supplements’ omega-3 content, their mercury levels, and whether the supplements showed signs of rancidity. First, they found that 6 out of the 30 supplement brands contained omega-3 levels that were, on average, 30 … [Read more...] about Do you know what’s in your fish oil supplement?
SANTA CRUZ – People buying certain fish oil supplements to get the benefit of omega-3 fatty acids are ingesting chemicals banned in 1979, according to environmental advocates who filed a lawsuit Monday aimed at forcing manufacturers to warn consumers. The lawsuit names five makers of supplements found to contain polychlorinated biphenyl compounds, drugstores CVS and Rite Aid, which sell those products, and Omega Protein Inc., of Houston, which touts itself as the world’s largest producer of omega-3 fish oil. Attorney David Roe filed the suit in San Francisco Superior Court contending Proposition 65, a law he helped write, requires consumers to be warned when products contain toxic ingredients above the limit deemed safe by regulators. Some of the tested supplements exceed California’s daily limit for PCBs by a factor of 10 in terms of the cancer risk, Roe said. A limit has not been set for the risk of birth defects. The U.S. Environmental Protection Agency has … [Read more...] about Lawsuit claims PCBs found in 10 fish oil supplements; product labeling sought
