Multiple risk factors for heart disease may be reduced by consumption of omega 3 fatty acids. In details, it can increase levels of “good” high density lipoprotein (HDL) cholesterol, lower triglycerides, the fat in the blood, reduce blood pressure in those with elevated levels, prevent the plaques that cause your arteries to harden, keep blood platelets from clumping together, and reduce fatal arrhythmia events, which are abnormal heart rhythms that can cause heart attacks in certain cases. Taking omega 3 supplements regularly may prevent depression and anxiety. Omega 3 also may reduce the symptoms of attention deficit hyperactivity disorder (ADHD) such as hyperactivity, inattention, impulsiveness and aggression. DHA, a type of omega 3, is known to reduce risk of macular degeneration, the world’s leading causes of permanent eye damage and blindness, because DHA is a major structural component of the retina of human eyes. Omega 3 fatty acids can reduce the production of molecules and substances linked to inflammation, such as inflammatory eicosanoids and cytokines.
