The new study, published in the Journal of Bone and Mineral Research, analysed blood samples from women with and without a history of having a broken hip - finding that those with higher levels of omega-3 fatty acids from both plant and fish sources in their blood were associated with a lower likelihood of having a fractured hip.
In addition to simply looking at omega-3 levels, the researchers also looked at omega-6 fatty acids - which are generally plentiful in a Western diet - finding that as the ratio of omega-6 fatty acids to omega-3's increased, so did the risk for hip fracture. Read Article
The researchers found that those with higher levels of fish consumption and omega 3 supplements scored significantly better in all domains of quality of life. The association was stronger for those consuming fish in comparison to those taking omega 3 supplements.
Although there was a trend towards increasing doses of omega 3 supplementation and lower relapse rates, this did not reach statistical significance. On the other hand, there was a significantly lower relapse rate for those taking flaxseed oil. The researchers also found that those consuming fish 3 or more times per week and those taking flaxseed oil were more likely to have normal or only some disability. Read more
Flaxseed oil, which is rich in n-3 fatty acid, is commonly consumed by breast cancer patients because of its potential anti-cancer effects. Trastuzumab (TRAS) is the primary drug for epidermal growth factor receptor 2 (HER2) positive breast cancer. This research shows that Flaxseed Oil did not interfere with TRAS but rather enhanced its tumor-reducing effects and combined Flaxseed Oil and low dose TRAS was as effective as high dose TRAS treatment. Abstract
Flaxseed has been shown to attenuate mammary tumorigenesis, possibly due to its high α-linolenic acid (ALA) rich oil (Flax seed Oil) content. Flax Seed Oil regressed estrogen receptor-positive human breast tumorigenesis at high E2 levels via downregulation of the growth factor mediated pathway, likely through its ALA content, and may explain the anti-tumorigenicity of Flax Seed. Abstract
A meta-analysis published in the recent issue of the American Journal of Clinical Nutrition evaluates how the plant-based omega-3 fatty acid alpha-linolenic acid (ALA) offers protective effects on cardiovascular diseases (CVD). The study found ALA to be associated with a lower risk of CVD, particularly coronary heart disease (CHD) death. These findings support the potential heart health benefits of ALA and suggest consumers should obtain adequate amounts of ALA in their diets.
This systematic review incorporated 27 original studies and included 251,049 individuals and found that overall ALA exposure was associated with lower risk of CVD. In fact, in the pooled dietary analysis, each 1 gram per day increment of ALA intake was associated with a 10% lower risk of CHD death. Previously, the majority of research funding of omega-3 fatty acids have been directed towards marine sources, however recently increased attention has been given to its plant-based counterpart ALA, and has been suggesting that ALA consumption also offers cardiovascular benefits. The researchers believe that there may be a direct or indirect antiarrythmic effect of ALA that could partially explain why ALA appeared protective against CHD. Previous studies have found ALA consumption may lower cholesterol levels, positively affect thrombosis, improve endothelial function and decrease inflammation.
The type of omega-3s found in plant sources are different from the type of omega-3s found in fish. According to Penny Kris-Etherton, Ph.D., Distinguished Professor of Nutrition at The Pennsylvania State University, consumers need to understand the nutritional benefits of plant-based omega-3 fatty acids. She notes that "research is showing that the effects of ALA may have unique and independent benefits important to our wellbeing."
Cardiologist Dr. James Beckerman finds this study extremely noteworthy and suggests people include more ALA rich food sources into their diet to promote heart health and potentially lower the risk of fatal cardiac events. "Given that plant sources of ALA are cheaper and more accessible to many people as compared to omega-3 fatty acids from fish, this study expands our arsenal to fight heart disease with safe and well tolerated dietary interventions that are easy for people to incorporate into their lifestyles," notes Dr. Beckerman.
The Institute of Medicine (IOM), which establishes nutrient requirements, recommends that people should consume 1.1 to 1.6 grams a day of ALA which can easily be attained. Abstract and Full Study
ALA may serve as a potent anti-inflammatory agent in ocular surface inflammation. The anti-inflammatory effects of ALA are comparable to those of corticosteroids. This study evaluated the in vitro anti-inflammatory effects of PUFAs on human corneal epithelial (HCE) cells. Read more
A recent study suggests that flaxseed oil supplementation may be beneficial for skin sensitivity and condition. According to the study, dietary fatty acids may modulate skin properties, such as hydration. Flaxseed oil is a rich source of the essential fatty acid alpha-linolenic acid, which is a precursor to omega-3 fatty acids. Read more
A new study reports that flaxseed oil may be helpful in lowering blood pressure. The study authors concluded that there was an observed blood pressure-lowering effect of ALA, which may constitute another mechanism accounting in part for the apparent cardioprotective effect of this n-3 fatty acid.

Dietary substitution with an alpha-linolenic acid (ALA) -rich vegetable oil increases eicosapentaenoic acid (EPA) concentrations in tissues. Read more
If demands for EPA and DHA are modest and primarily serve to support membrane turnover and renewal in adults, then it is possible that in healthy individuals consuming a balanced diet the capacity for synthesis of EPA and DHA may be sufficient to maintain tissue function. Read more
A diet high in PUFA, especially ALA, elicits cardioprotective effects by decreasing lipid and lipoprotein levels and by eliciting vascular anti-inflammatory effects. The fact that ALA has marked, beneficial effects on multiple CVD risk factors further underscores its potentially important role in CVD risk reduction. These findings provide additional support for the importance of ensuring adequate PUFA and ALA intake as a strategy to markedly lower CVD risk. Read more

Flax has been part of human history for well over 30,000 years, used for weaving cloth, feeding people and animals, and even making paint. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania have discovered that it might have a new use for the 21st century: protecting healthy tissues and organs from the harmful effects of radiation.
