Define Omega 6

Omega-6 is an unsaturated fatty acid that has a carbon-carbon double bond in the n-6 position (the sixth bond from the end of the lipid chain). Omega-6 is naturally found in many foods, and high levels of omega-6 intake may increase the likelihood of several cancers and counteract the health benefits of omega-3 fatty acids. Some nutritionists believe the ratio of omega-6 to omega-3 intake is the key to healthfulness, rather than the specific amount of either nutrient.

  1. Dietary Sources

    • Omega-6 fatty acids are found in several food oils, including sunflower, palm, soybean and most vegetable oils. They are also found in eggs, avocado, poultry and nuts. Because many processed foods are made with soybean or vegetable oil, dietary intake has risen dramatically and omega-6 fatty acids can now be found in fast foods, crackers, cookies and snacks.

    Types

    • There are nine types of omega-6 fatty acids. In no particular order, they are: Adrenic acid, Docosadienoic acid, Docosapentaenoic acid, Linoleic acid, Arachidonic acid, Gamma-linolenic acid, Dihomo-gamma-linolenic acid, Calendic acid and Eicosadienoic acid.

    Impact on Health

    • Once digested, the body uses omega-6 fatty acids to construct hormones. These hormones are used by the immune system to increase inflammation, and also for blood clotting and cell reproduction. Omega-3 fatty acids have the opposite effect, which is why it is important to balance the intake of both nutrients. As a result of increased soybean and vegetable oil intake, omega-6 fatty acids are being consumed far more than omega-3 fatty acids. Scientists believe this imbalance has contributed to the rise in asthma, heart disease, several forms of cancer and autoimmunity disorders; these problems all stem from inflammation in the body.

    Impact on Mental Health

    • The imbalance between omega-6 and omega-3 intake may also have consequences for your mental health. Obesity, depression, dyslexia, hyperactivity and violent tendencies have all been linked to disproportionate levels of omega-6 and omega-3 fatty acids. One study conducted in a British prison found that violence among inmates dropped by 37 percent when omega-3 oils and vitamins were added as dietary supplements.

    Potential

    • In addition to their natural functions within the body, researchers believe omega-6 fatty acids may be useful in treating a wide variety of medical conditions, from alcoholism to ulcers. However, research exploring the benefits of increased omega-6 intake has so far focused mainly on animals. More studies are necessary to determine whether omega-6 supplements would be beneficial to people suffering from the same conditions.
