Definition of Omega 6

Omega-6 fatty acids are essential nutrients found in the foods we eat. Together with omega-3s, they form the good fats that keep our hearts and brains healthy.

  1. Classification

    • Omega-6s are polyunsaturated fatty acids, or PUFAs. They are similar to omega-3 fatty acids except for minor differences in chemical composition. PUFAs are considered essential nutrients because they cannot be manufactured by the human body.

    Sources

    • Omega-6 fatty acids can be found in nuts, seeds and vegetable oils. Some 85 to 90 percent of the omega-6 fatty acids in these foods is in the form of linoleic acid.

    Function

    • Along with omega-3s, omega-6 fatty acids help with heart and brain health. These PUFAs also play a role in normal growth and development.

    Recommended Intake

    • The American Heart Association (AHA) recommends that people get 5 to 10 percent of their daily calories from omega-6 fatty acids. For most people, this equates to approximately 12 to 22 grams per day.

    Debate

    • In recent years, scientists have debated about the ideal intake levels of omega-6 fatty acids. Despite the AHA's recommendations, some argue that omega-6s should be eaten only sparingly. These scientists recommend a diet higher in omega-3 fatty acids.
