Why do omega-6 fatty acids cause inflammation?

Grant Cooper, MD
Physical Medicine & Rehabilitation
Omega-6 fatty acids are proinflammatory, because they are broken down by the body and converted into prostaglandins and other inflammatory proteins. These proteins cause inflammation. In fact, steroids and nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, work by blocking the formation of these same inflammatory proteins.

Omega-3 fatty acids are also converted into inflammatory proteins, but this conversion takes place much more slowly, so that the body's natural mechanisms of breaking down inflammatory mediators occur before inflammation has a chance to take place. When you consume omega-6 fatty acids, inflammatory proteins are built so quickly that the body's natural process of metabolizing them is overwhelmed, and inflammation and its symptoms are much more likely to occur. Unchecked inflammation may be a factor in the development of a number of diseases, including heart disease. Obviously, ingesting substances that create more inflammatory proteins in the body is not good for people struggling with arthritis.
