DHA Benefits
The main marine omega 3 fatty acids are eicosapentaenoic acid (EPA), docosapentaenoic acid and docosahexaenoic acid (DHA). It is of interest that DHA is specifically localised in the retina and the brain in humans and other mammals. The longer chain omega 3 fatty acids are rapidly incorporated into cell membrane phospholipids where it is regarded they influence the metabolism/metabolic events within the cells. The mechanisms by which these changes occur include alteration in the fluidity of membranes such that there are subtle changes in receptor function, alteration in cell signalling mechanisms, membrane-bound enzymes, regulation of the synthesis of eicosanoids, and regulation of gene expression.
     Fish and fish oils may be beneficial in reducing the risk for heart disease, heart arrhythmias, mental decline, and may also help reduce symptoms of arthritis and several autoimmune conditions. Eating fish and perhaps taking fish oil supplements may also help reduce the risk for macular degeneration. Fish oils are found in sperm, and these oils may support healthy sexual organ function.
      Dr. Malcolm Peet of the Swallownest Court Hospital in Sheffield, England and his colleague found that depressed patients who received a daily dose of 1 gram of an omega-3 fatty acid for 12 weeks experienced a decrease in their symptoms, such as sadness, anxiety and sleeping problems.

DHA Supplement for a Vegetarian Diet
Docosahexaenoic acid supplementation in vegetarians effectively increases omega-3 index: a randomized trial.

Low red blood cell (RBC) membrane content of EPA + DHA (hereafter called omega-3 index) has recently been described as an indicator for increased risk of death from coronary heart disease. The relationship between plasma and RBC fatty acids, focusing on omega-3 index, and the response to DHA supplementation were investigated in a double-blind, randomized, placebo-controlled, intervention study. Healthy vegetarians consumed daily a microalgae oil from Ulkenia sp. (0.94 g DHA  per day) or olive oil (placebo) for 8 wk. DHA supplementation significantly increased DHA in RBC total lipids and in plasma phospholipids whereas EPA levels rose to a much lesser extent. Microalgae oil supplementation increased the omega-3 index from 4.8 to 8.4 wt%. After intervention, 69% of DHA-supplemented subjects (but no subject of the placebo group) reached an omega-3 index above the desirable value of 8 wt%. We conclude that an 8-wk supplementation with 0.94 g DHA/d from microalgae oil achieves a beneficial omega-3 index of > or =8% in most vegetarian diet subjects with low basal EPA + DHA status.

DHA--Seeing is Believing
The rods and cones of the retina in the eyes are very rich in DHA. Hence, a deficiency in dietary fish oils will reduce the photoreceptor activity of retinal cells, and may reduce visual acuity. On the other hand, supplementation with fish oils (or flaxseed oil) could lead to visual improvement with enhanced color perception.
        Since levels of DHA in the brain decline with age, it is likely that the levels of DHA also decline in the retina. Is it possible that daily intake of fish oils can improve vision in older individuals? Hopefully future research can give us some answers.

Reduce the risk of sudden death with omega-3s
An editorial in Circulation: Journal of the American Heart Association suggests that increasing dietary omega-3 fatty acids, which come from fatty fish or flaxseed oil, and decreasing omega-6 fatty acids, found in plant seed oils such as corn, safflower, and sunflower, is a way to reduce the risk of sudden death from irregular heart rhythms or heart attacks.
        One cause of sudden death is ventricular fibrillation, in which the heart contracts in a fast and chaotic rhythm that makes it unable to pump blood to the rest of the body. A number of factors including cigarette use, fasting, diabetes, hyperthyroidism or heart attack can trigger the release of fatty acids from adipose tissue.
        Fats that we eat are stored in adipose (fat) tissue. When these fats are released from their storage sites, they become free fatty acids. But not all fatty acids are equal in their propensity to cause arrhythmias. High levels of omega-6 fatty acids may encourage arrhythmias if their levels aren’t balanced by omega-3 fatty acids.
