After a three week period of adding eight grams of fish oil to their patients' daily diet, the researchers found not only a significant lessening of pain and discomfort from bedsores - a 20 to 25 percent improvement, according to the Pressure Ulcer Scale for Healing - but also a more efficient immune system and a reduction to inflammation throughout the body. The results were reported in the British Journal of Nutrition and the American Journal of Critical Care.
