Arachidonic Acid (AA)

Arachidonic acid (AA) is considered the main pro-inflammatory omega-6 fatty acid, which is found in foods such as vegetable oils, butter, poultry and red meat. This is typically compared as a ratio to eicosapentaenoic acid (EPA), a major anti-inflammatory omega-3 fatty acid found primarily in fatty fish. The ratio AA:EPA may serve as an indication of the amount of inflammation in the body.
