Omega 6 fatty acids is a type of unsaturated fats (unsaturated fat) that is found in vegetable oils, nuts and seeds. If consumed sparingly, Omega-6 gave a great benefit to health especially keep the organ of the heart and brain.
But lately, it appears some of the controversy surrounding the omega-6. In fact, some studies claim, omega-6 are metabolized in the body can be turned into fat causes damage and inflammation of the blood vessels. Inflammation or damage that is what will cause constriction of blood vessels (arteries), which ultimately trigger heart disease.
Related to this, Donald Hensurd, MD, a preventive medicine experts from the Mayo Clinic says that it is simply not true. Even his opinion, the American Heart Association (AHA) has recommended that a person must fulfill 5-10 percent of daily calories from omega-6 fatty acids.
Some literature mentions, the need for omega-6 for healthy adults is 1-3 grams/day, if that amount is not met then it could potentially happen body metabolism disturbances.
Omega-6 fatty acids have some type of linoleic acid, gamma-linolenic acid and from arachidonic acid. The body converts linoleic acid to gamma-linolenic acid and from arachidonic acid.
Food sources rich in linoleic origin such as some vegetable oil (sunflower oil, soybean oil, corn oil, walnut oil and sesame oil), nuts (almonds and walnuts, cashew), and seeds (flax, hemp, sunflower, Sesame, and pumpkin). Foods that are high in gamma-linolenic acid is an acid such as evening primrose flower oil, borage oil, black currant seed oil. While the food is arakidonatnya acid levels high as animal meats, egg yolks and shellfish.
In some literature is mentioned, the intake of omega-6 fatty acids also have to be balanced with other essential fatty acids including omega-3. According to experts, the omega-3 fatty acids and omega-6 has a function related to each other. Both are working to synergize maintain healthy skin, nails, hair, the hormones, alleviate the symptoms of asthma, as well as preventing damage to the person with cancer.
That being the issue, the ratio of omega-3 and 6 are in balance is still a debate among experts. Some say 2.5 to 1, the figure of 2.5 to omega-6 and 1 for omega-3. There is also a said 4-to-1.
Hensurd said, if someone was concerned about the amount of intake of omega-6 who have their consumption, we recommend that you consult a doctor or replacing the menu foods that contain saturated fats with healthier choices.
