A detailed research report by the authors suggests that higher intake of seafish or oil rich in long-chain omega-3 polyunsaturated fatty acids may be beneficial for the aging brain.
This interventional study demonstrates enhanced executive functions in healthy older adults after 26 weeks of high levels of supplementary marine long chain -omega 3- fatty acids compared with placebo. which is in line with previous studies reporting beneficial effects of long chain -omega3 - fatty acids on cognition.The study shows positive effects of long chain -omega3 - fatty acids on neuronal function.
These findings may help to develop new prevention and treatment strategies for maintaining cognitive health into older age.

The present study aims to understand the hepato protective potential of omega-3 fatty acids in the form of flaxseed oil and fish oil. The study concludes that flaxseed oil or fish oil prevents hepatic damage with marked improvement in hepatic function and normalization of lipid profiles in serum and liver. The protective effects of fish oil and flaxseed oil are mainly attributed to long chain polyunsaturated fatty acids like ALA, EPA and DHA. These fatty acids have been shown to have antioxidant properties and play an important role in overall metabolism.

Fish oil containing ω-3 polyunsaturated fatty acids (ω-3 PUFAs) including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is known to prevent the progression of nephropathy and retard the progression of kidney disease. This study provides extremely novel insights into the mechanisms of the renoprotective effects of fish oil.

The present study carefully investigates the benefits of supplementing a diet with ω-3 PUFA, DHA and EPA, for depressive symptoms, quality of life (QOL) and cognition in elderly people with MCI.
In conclusion, these results indicate that DHA-rich and EPA-rich fish oils may be effective for depressive symptoms and health parameters, exerting variable effects on cognitive and physical outcomes.

Polyunsaturated fatty acids can have beneficial effects on human immune cells, such as peripheral blood mononuclear cells (PBMCs).This pioneering research shows that intake of EPA+DHA for 26 weeks can alter the gene expression profiles of PBMCs to a more anti-inflammatory and antiatherogenic status.

Dietary omega-3 fatty acids have been demonstrated to have positive physiological effects on lipid metabolism, cardiovascular system and insulin resistance.Type-2 diabetes (T2DM) is known for perturbations in fatty acid metabolism leading to dyslipidemia.
The authors say " Dietary flaxseed oil and fish oil have therapeutic potential in preventing lipid abnormalities in T2DM.”

This research was to study the effect of dietary intake of ω-3 fatty acids on the course of coronary artery atherosclerosis in humans.
The authors precisely observe that patients with coronary artery disease who ingested approximately 1.5 g of ω-3 fatty acids per day for 2 years had less progression and more regression of coronary artery disease on coronary angiography than did comparable patients who ingested a placebo..”
Scientific Opinion on the Tolerable Upper Intake Level of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid

Optimum level of EPA and DHA intakes are studied by the panel and reported . The Panel considers that supplemental intakes of DHA alone up to about one gram per day do not raise safety concerns for the general population .
