On the other hand, oily fish is rich in long chain omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are the forms of omega-3 fats that the body can immediately use and are considered to be the most valuable for our health.
The conclusion is clear, you need more omega-3 fats because they are useful for:


Scientific studies that are carried out for decades indicate a link between increased intake of omega-3 fatty acids and reduced risk of heart disease. It has been shown that EPA and DHA reduce the level of triglycerides in the blood and play an important role in functioning of the cardiovascular system. Omega-3 fatty acids facilitate the regulation of blood pressure, which is of great significance because hypertension is a major risk factor for stroke. Numerous studies have shown that omega-3 fats allow maintenance of heart health as: maintain optimal attenuation levels of blood, which prevents thrombus formation and reduces inflammation in patients with heart disease, reduce the risk of cardiac arrhythmia’s, raise levels of good cholesterol (HDL), while lowering down the level of harmful cholesterol (LDL), slow down the formation of arterial plaque, which often leads to hardening of the arteries and increase the risk of coronary disease.


DHA is essential for vision preservation. The newest studies have shown that DHA keeps eye health and prevent the deterioration of eyesight. In addition, this acid is very useful in case of dry eye syndrome, which is usually caused by everyday work in front of computers. Tests have shown that omega-3 fatty acids significantly relieves the symptoms of this disorder and creates a protective film on the surface of the eye, which prevents drying out and the appearance of symptoms.


Scientific studies substantiate the claims of our grandmothers that fish oil is essential for healthy brain. It has been proved that DHA is vital for normal brain function (40% fat in the membranes of brain cells are made of DHA), while the EPA considers supporting transmission of signals between brain cells, and maintain vascular health. DHA also plays an important role in brain development in babies, which is another reason for this supplement to be used by pregnant women and nursing mothers. In a US study, which involved children aged seven to nine years, were established a direct link between increased intake of omega-3 fats and achieving better results on cognitive tests. English researchers found that higher levels of omega-3 fats in the body increase the effect of vitamin B-complex, which are known to prevent the weakening of mental abilities.
