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.

Researchers map processes that power health benefits of omega-3 fatty acids

For the first time, researchers at the University of California, San Diego have peered inside a living mouse cell and mapped the processes that power the celebrated health benefits of omega-3 fatty acids. More profoundly, they say their findings suggest it may be possible to manipulate these processes to short-circuit inflammation before it begins, or at least help to resolve inflammation before it becomes detrimental.

Symposium at EuroPRevent 2012 highlights benefits of oily fish consumption

Most people, whether healthy or having cardiovascular disease (CVD), would benefit from regular consumption of oily fish, concluded speakers at the EuroPRevent 2012 meeting. While eating whole fish undoubtedly offers the optimum approach for increasing omega-3 intakes in both primary and secondary prevention, delegates heard, supplements have a major role to play in increasing omega-3 intakes for people who do not like fish.

Omega-3 supplements do not improve diastolic function in older adults

Over the past three decades, researchers have firmly established that the omega-3 fatty acids in fish oil, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have healthy effects on the heart. Omega-3 fatty acids seem to help both in preventing cardiovascular disease as well as in preventing future heart attacks, strokes, and other adverse events in people who have established cardiovascular disease.

Fish oil not as beneficial for the heart as thought: Study

Fish oil, a combination of omega-3 fatty acids that has attracted much research on its effects on heart health. So far, the evidence has been inconclusive -- some studies have found fish oil has been major in preventing heart attacks, strokes and sudden cardiac death, while others have found fish oil has no benefits at all.

Walnuts associated with better memory scores and cognitive function

Do you recall what you ate for breakfast today or dinner last night? According to new research, you may have a better chance of remembering if you include walnuts. Recent findings published in the Journal of Alzheimer's Disease report walnut consumption in a Mediterranean diet is associated with better memory scores and cognitive function.

Low levels of omega-3 in blood ‘ups’ risk of dementia and brain aging: Study

Researchers looked at 1,575 adults who averaged 67 years old and had no signs of dementia and had not had a stroke. They were given MRI brain scans and a battery of tests to measure memory and thinking abilities; they also had blood drawn to check the level of docosahexaenoic acid (DHA) or omega-3 fatty acids in their red blood cells. Those with the lowest levels of omega-3s showed signs of accelerated aging. They had lower brain volume, indicating shrinkage comparable to two additional years of aging. Compared with those with the highest blood levels of omega-3s, they scored lower on cognitive tests measuring such things as memory, problem solving, abstract thinking and multi-tasking.

Diets low in omega-3 fatty acids linked with memory problems

A diet lacking in omega-3 fatty acids, nutrients commonly found in fish, may cause your brain to age faster and lose some of its memory and thinking abilities, according to a study published in the February 28, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology.
