Polyunsaturated fatty acids from oily fish prevents cardiovascular events, which are the leading cause of mortality worldwide. Its use is recommended especially for patients with heart disease, but also to the general population. The blue fish meat is not only rich in omega 3, but has many more benefits.

Regular consumption of polyunsaturated fatty acids, especially omega 3, is suitable for individuals with cardiovascular risk and for the general population. Fish is a food rich in this nutrient. Even a recent study has found that its value “exceeds that of a nutritional supplement food base to set itself up.” Its benefit in terms of cardiovascular prevention, is considered as important as the statin drugs that reduce cholesterol levels.

The study’s lead author, Carl J. Lavie, at Ochsner Medical Center (New Orleans, USA), investigated in healthy people and survivors of myocardial infarction, patients with heart failure, atherosclerosis or atrial fibrillation. The results of monitoring, which lasted 30 years, have been published in the Journal of the American College of Cardiology.
Culture of omega 3

Consumption of polyunsaturated fatty acids not only benefits individuals with cardiovascular risk, but the entire population.

Lavie regrets that many physicians assume that the fish oil fatty acids, especially omega-3 health benefits, without stopping to inquire by what means, how and to what extent. Censorship that many physicians are aware of the tests carried out with statins, but are unaware of recent publications related to omega 3. In heart failure and patients who have suffered a heart attack, it has proven to prevent deaths and hospitalizations.

It is estimated that these groups should take oily fish in meals, at least four or five times a week.

The most studied are omega-3 docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The clinical benefits of these fatty acids have been shown in a total of four trials conducted with 40,000 patients, with and without cardiovascular disease.

The average decrease in risk over 30%. The benefits do not follow the stroke, but cover the atherosclerotic disease and a broad range of arrhythmias.

On the latter, a study designed to investigate the benefits of omega 3 in the prevention of atrial fibrillation, an arrhythmia own people without apparent cardiovascular risk factors (smoking, obesity, hypertension or diabetes) but due to a excessive and continuous practice of intense physical exercise (cyclists, climbers, marathon runners, etc..), heart arrhythmias is beginning to feel the fifth or sixth decade of life.

In the study, also recognizes that a vegetable omega 3, linolenic acid (ALA), exercise a profit comparable to the fatty acids from fish. However, scientific evidence places the benefit of the latter “far short” of the animal.

FISH BLUE

The excellences that are attributed to the blue fish, especially tuna, are encountering a major problem for sustainability and biodiversity. There are 12 species of tuna that live in all oceans of the planet, but the International Union for Conservation of Nature (IUCN) has already given a letter of “species near extinction,” to five (four of them in serious danger) : yellow fin tuna or light tuna (Thunnus albacares), southern bluefin tuna (Thunnus maccoyii), big-eyed tuna (Thunnus obesus), albacore (Thunnus alalunga) and bluefin tuna (Thunnus thynnus “).

Associations such as Greenpeace confirm that, after more than 3,000 years of fishing, bluefin tuna in the eastern Atlantic and Mediterranean is on the brink of extinction. They stress that only 10 years have been enough of “uncontrolled development” by the fishing industry to the fence to endanger the survival of the species.

These partnerships are critical to the action taken by the European Union and Member States to protect bluefin tuna are inadequate and ignored complaints from fishermen, scientists, wholesale fish merchants, retail chains and NGOs like WWF. Bluefin tuna is the largest of this species. It differs from others in that its pectoral fin is shorter and the color of their flesh, darker. Frequents different waters, as with muscle activity can elevate your blood temperature above the water.

May reach three meters and weighing between 130 and 600 kg. Their life expectancy in the wild more than 20 years. It feeds on other smaller fish such as sardines, mackerel and horse mackerel. Their natural predators at sea are sharks and killer whales, although anyone who puts their survival at stake now is the human being.
