Omega 3 Fatty Acid News and Research

RSS

Omega-3 is an essential fatty acid (EFA), consisting of EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). Oily fish, including anchovies, sardines, mackerel, and salmon, are the only known natural sources of Omega-3 EPA/DHA. ALA is found in plants, such as flax and chia. It is important to note that only EPA and DHA contribute to the many health benefits associated with Omega-3. While the body can convert ALA into EPA/DHA, it does so very inefficiently (less than one percent), making it impossible to derive Omega-3-related health benefits from plant sources. Furthermore, although Omega-3 EPA/DHA is vital to overall good health, the human body is not able to produce it on its own, so supplementation is required, either by eating oily fish or foods fortified with Omega-3 EPA/DHA, or by taking fish oil supplements.

Fish oil shown to reduce airway inflammation caused by exercise-induced asthma

People suffering from exercise-induced asthma were able to reduce their symptoms below the threshold used to diagnose the disease by eating a diet supplemented with fish oil, according to new research findings from Indiana University reported in the January issue of the journal Chest.

Fish oil supplements prevent declines in heart rate variability

A two-gram fish oil supplement given daily to elderly persons prevented a decline in heart rate variability caused by tiny, dangerous airborne pollutant particles. Heart rate variability, a measure of the autonomic nervous system's regulation of the heart, is an independent risk factor for cardiac arrhythmias, heart attack or sudden death.

Americans need to eat more fish

The sooner people start eating more fish rich in omega-3 fatty acids like salmon and tuna the better. Having fallen out of favor due to past mercury warnings aimed at pregnant women, new data show that consumers are doing their bodies a disservice if they continue to avoid this food.

Abnormal heart rate variability is partially responsible for depression's effects in heart patients

Scientists have known for years that depression increases the risk of dying in the months after a heart attack, but they haven't understood how depression raises that risk.

Fish may help prevent heart failure as well as heart attacks

Older people who ate fish once or twice a week had a 20 percent lower risk of developing congestive heart failure during 12 years of follow-up, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.

Fish oil not a good idea for heart defibrillator patients

For heart patients who have surgically implanted defibrillators to shock their weakened hearts back into rhythm, fish oil supplements are not a good idea and in fact appear to do more harm than good.

Fish oil does not lower risk of serious heart rhythm abnormalities for patients with implantable defibrillators

Even though previous research has shown that fatty acids from fish oil reduce the risk of sudden cardiac death, patients with implantable defibrillators who took fish oil supplements did not see a reduction in serious heart rhythm abnormalities, according to a study in the June 15 issue of JAMA: The Journal of the American Medical Association.

Modifying your salt intake has the potential to prevent exercise-induced asthma

An Indiana University professor may have uncovered the mechanisms by which high-salt diets can trigger exercise-induced asthma, offering the most complete picture to date of how dietary factors can both aggravate and alleviate the symptoms of this common condition.

Omega-3 combined with propofol may lead to new drugs to treat breast cancer

Omega-3, the fatty acid found in oily fish, could be combined with a commonly used anesthetic to develop drugs to treat breast cancer, according to research published in the journal Breast Cancer Research.

New clue to understanding how fatty acids work in the brain

Scientists in Cambridge have discovered that a brain protein called syntaxin enables fatty molecules, used widely in health supplements, to work in the brain to make it function properly. Lead Scientist, Dr Bazbek Davletov and his colleague Dr Colin Rickman from the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK report their findings in the journal Chemistry and Biology.

'Bad' metabolism cloggs up arteries

Scientists are now saying that a 'bad' metabolism may explain why some people who have never smoked and do not have high cholesterol levels suffer from a potentially lethal build-up of plaque in the arteries.

Brain fatty acid levels linked to depression

A group of researchers from Israel has discovered that rats exhibiting the signs of depression have increased levels of the omega-6 fatty acid, arachidonic acid, in their brains. The details of their findings appear in the June issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal.
