Most people tend not to understand that our body has it's own anti-inflammatory chemicals that it utilizes to control inflammation. This on board system that our body utilizes to manage inflammation is sustained by a critical nutrient-- omega 3 . ( Lots of medical doctors appear to have forgotten this simple fact). If omega 3 fats are inadequate in the food we eat, which they are for all Westerners then your body doesn't have the raw material that it needs to get to create it's own anti-inflammatory substances. Consequently inflammed articulations remain inflammed and very painful. However when you replenish these critical omega 3 fats by taking a fish oil nutritional supplement, the body system starts producing it's own anti-inflammatory chemicals again and the pain and inflammation go away.
