Precision Medical Nutrition Intervention in Oncology Patient

Introduction: The role of nutrition in cancer survivorship and palliative care has received significant interest in clinical community.Addressing the potential benefits of nutritional intervention in three forms of ۱-nutritional counselling,۲-nutritional education and ۳-diet planning and medical nutrition therapy should be taken into account to achieve positive outcomes. Methods: The most recent scientific reports related to nutritional intervention in oncology patients from International Agency for Research on Cancer,America Cancer Society,American Institute for Cancer Research, the World Cancer Research Fund, National Cancer Institute,MDanderson Cancer Center, Canadian Cancer Society,Cancer Council Victoria,Cancer Research UK,American Society of Enteral and Parenteral Nutrition,American Dietetics Association and British Dietetics Association has been reviewed. Results: The quantity of food servings to select at meals/snacks,improving food choices and nutrient density should be consulted. When determining calorie requirements, best practice should be precision (personalized) and based on clinical judgment(hypercatabolism,renal disease, hepatic disease or stem cell transplant), activity and stress factors, body weight and monitoring refeeding syndrome. When foods aren't tasting right, poor appetite, bowel movement problem, constipation, diarrhea, difficulty swallowing, sore or irritated throat/mouth, feeling queasy, high blood sugar, dry mouth or thick saliva are presented, medical nutrition therapy should take into consideration these complications. Fat profile of foods, glycemic index of foods, potassium content of foods, food safety guide(clean,separate,cool,chill) to reduced food borne illness should be educated to oncology patients. Conclusion: One nutrition intevention doesn't fit all. Once the process initiated it is important to based on patient's medical and dietary history.
