 Recent studies have shown that certain types of fats that are present in fish, walnuts and other foods that we eat called Eicosapentaenoic acid EPA may help with weight gain, especially gain in muscle and improve quality of life in patients with pancreatic cancer. However, EPA has never been studied in prevention of cancer cachexia in cancer patients showing early signs of weight loss. Based on these early, small studies, it is clear that we need to study if and how EPA can prevent loss of muscle and weight in cancer patients and prevent this from becoming worse.
