Omega-3 polyunsaturated fatty acids (pufas), such as eicosapentaenoic acid and docosahexaenoic acid, are widely regarded as cardioprotective several large-scale, randomized clinical trials have shown that dietary intake of omega-3 pufas improves the prognosis of patients with symptomatic heart failure or recent myocardial infarction.

Polyunsaturated fatty acids benefits of polyunsaturated fatty acids in diet polyunsaturated fatty acids are also called omega 3 fatty acids they have a double bond of carbon and carbon the second carbon bond starts just at the edge of the first carbon bond. The cardiovascular protective effect of omega-3 polyunsaturated fatty acids (n-3 pufas), especially for eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) has been well documented (de caterina, 2011, mozaffarian and rimm, 2014. The benefits of the polyunsaturated fatty acids have been controversial in some medical acceptances and language, they are called essential fatty acids the meaning behind this is that they cannot be synthesized by the body cells and metabolic activities.
Background high consumption of fish carries a lower risk of cardiovascular disease as a consequence of dietary omega-3 long chain polyunsaturated fatty acid (n-3 pufa especially epa and dha) content. The cardioprotective effects of food rich in omega-3 (omega-3) polyunsaturated fatty acids (pufa) on cardiovascular risk has been of interest from the moment when a low rate of coronary heart disease was documented in the eskimo population. There is a long history of clinical research showing that long-chain omega-3 fatty acids - the kind of fatty acids found at relatively high levels in fish oils - have a cardio-protective effect this research includes several large randomized control trials (rcts.

Dietary ω-3 polyunsaturated fatty acid (pufa)-enriched fish oil (fo) has been shown to reduce the severity of certain types of cancers, cardiovascular disease, and renal disease.
In this report we study the effects of the polyunsaturated fatty acids (pufa) on proliferation and signal transduction in the interleukin-2 (il-2)-dependent murine t cell line ctll-2. Polyunsaturated fat is a type of dietary fat it is one of the healthy fats, along with monounsaturated fat it is one of the healthy fats, along with monounsaturated fat polyunsaturated fat is found in plant and animal foods, such as salmon, vegetable oils, and some nuts and seeds.
