Ms. Murphy, a registered dietitian with over 20 years of experience as a consultant in the areas of dietary intake assessments, evaluation of the safety and efficacy of food ingredients and dietary supplements, and critical reviews of nutrition science information. She analyzes national dietary data to identify food consumption patterns, assess nutrient intake adequacy and diet quality, examine relationships between food and nutrient intakes and health measures, and model the nutritional impact of various fortification scenarios or other potential modifications to the diet.
Ms. Murphy has designed and completed numerous dietary exposure assessments using nationwide food consumption data from the United States such as the National Health and Nutrition Examination Survey (NHANES) data as well as other nationally representative datasets including data for the United Kingdom, Brazil, and China; for some analyses Ms. Murphy has developed custom databases of food constituents. Findings from these analyses have been published in the peer-reviewed literature and have been used to support product development efforts, marketing initiatives, product registration, and proposed changes in food labeling and dietary guidance.
Ms. Murphy also has extensive experience in evaluating the safety and efficacy of novel ingredients added to foods, medical foods, infant formula, and dietary supplements. Ms. Murphy has developed GRAS dossiers and other safety assessments for food additives such as prebiotics, phytonutrients, fatty acids, and proteins, and has convened Expert Review panels. Ms. Murphy has developed claims substantiation dossiers for structure-function claims on foods and dietary supplements. Ms. Murphy also has conducted numerous critical reviews on a variety of nutrition topics, including systematic reviews and meta-analyses; these reviews have been summarized as white papers, peer-reviewed papers, and components of regulatory submissions.
