Office of Dietary supplements summarizes the benefits of Omega 3 Fatty acids on health and conditions like Cardiovascular disease, heart function, asthma, cognitive function, organ transplantation and other conditions like joint tenderness and need for corticosteroid drugs in rheumatoid arthritis.
Studies show that Omega-3 fatty acids in general decrease triglyceride and very-low-density lipoprotein blood levels in hyperlipidemic individuals but may increase or have no effect on low-density lipoprotein (LDL) levels.
Most American diets provide more than 10 times as much omega-6 than Omega-3 fatty acids. There is general agreement that individuals should consume more Omega-3 and less omega-6 fatty acids to promote good health. Good sources of ALA are leafy green vegetables, nuts, and vegetable oils such as canola, soy, and especially flaxseed. Good sources of EPA and DHA are fish and organ meats. LA is found in many foods, including meat, vegetable oils (e.g., safflower, sunflower, corn, soy), and processed foods made with these oils.
Adverse events related to consumption of fish-oil or ALA supplements are generally minor and typically gastrointestinal in nature (such as diarrhea). They can usually be eliminated by reducing the dose or discontinuing the supplement.
