Chronic inflammation of tissue is linked to many age-related conditions; Reliability Theory suggests that the cellular damage caused by inflammation plays a large role in decreasing healthy life span. This Nature article discusses the first steps taken to uncover the biochemistry of fish oil (or rather the omega-3 fatty acids it contains) and how it suppresses inflammation. "[Charles Serhan's] group is also looking at the other lipids that derive from fish oil. He suspects that each one has a part to play in orchestrating the inflammatory response. Understanding how they work could lead to the development of a range of new drugs to counteract inflammation, he predicts."
