Fish oil can be a great resource for those with chronic pain to reduce the inflammatory process, thereby reducing pain. Omega-3 fatty acids (such as those found in oily fish like salmon, mackerel, and krill, as well as some plants and nuts) play an important role in neurological function. “Omega-3 fatty acids are highly concentrated in the brain and appear to be important for cognitive (brain memory and performance) and behavioral function” (Omega-3 fatty acids | University of Maryland Medical Center http://umm.edu/health/medical/altmed/supplement/omega3-fatty-acids#ixzz33WFWdOlh). It is important to try to balance your intake of omega fatty acids according to what type they are. Omega-3 fatty acids can help reduce inflammation, and the majority of omega-6 fatty acids can to promote inflammation. Many studies show a Mediterranean diet provides this proper balance, with more omega-3s and less omega-6s.
“Fish oil can [also] ease the inflammation and pain caused by many chronic conditions. The dose used in the most convincing research is 2 to 4 grams of DHA + EPA daily (read labels carefully!). Although beneficial omega-3 fatty acids are available from other sources, experts say that fish oil has the best evidence…they help with headaches, back pain, some nerve pain, and autoimmune conditions like rheumatoid arthritis.” (http://www.webmd.com/vitamins-and-supplements/lifestyle-guide-11/chronic-pain-relief)
