Mary M. Murphy, R.D.

Ms. Murphy, a registered dietitian, has over 11 years of experience as a consultant in the areas of dietary intake assessments, evaluation of the safety of food ingredients and dietary supplements, and nutrition science. Ms. Murphy analyzes national data to identify food consumption patterns, to examine relationships between food and nutrient intakes and health measures, and to model the nutritional impact of various fortification scenarios. Findings from these analyses have been used to support product development efforts, marketing initiatives, and product registration. Ms. Murphy’s experience with dietary exposure assessments includes use of U.S. and U.K. nationwide food consumption surveys, and development of databases of food constituents. Ms. Murphy also has extensive experience in evaluating the safety 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, carotenoids, fatty acids, and proteins, and has convened Expert Review panels. Ms. Murphy also has completed a wide range of projects on nutrition issues such as identifying opportunities for fortification based on nutrient intakes and status, and developing critical reviews of nutrition research.

Compared nutrient intakes and body measures among children and teenagers drinking flavored milk, exclusively plain milk, or no milk. This dietary intake assessment was completed with NHANES data and the results of the study were published in the peer-reviewed, scientific literature.

Developed a database of typical resistant starch concentrations in foods and in combination with food consumption data reported in NHANES, estimated ranges of resistant starch consumed in the U.S. by age and sex, and race/ethnicity. The relative proportions of resistant starch intakes from ten categories of foods were estimated for the total population and by race/ethnicity. Results of this study were published in the peer-reviewed, scientific literature.

Estimated nutrient intakes from beverages in the United States, and also compared intake of selected nutrients among subpopulations by patterns of beverage consumption. The analysis used data reported in NHANES and was limited to a sample population with plausible dietary recalls. A report was developed to accompany the research, and the results were used in a marketing campaign by a trade association.

Modeled the effects of various levels of nutrient fortification on nutrient intakes for several clients. One project involved assessment of nutrient intakes assuming different levels of whole grain substitution for refined grains in a variety of food categories.

Analyzed data detailing food and nutrient intakes by children to help identify patterns of consumption and potential nutrient inadequacies.

Developed exposure assessments for use in safety assessments related to food additives, potential contamination, and Prop 65 issues.

Completed safety assessments, prepared GRAS dossiers, and facilitated Expert Panel reviews for the use prebiotics in food and infant formula; also developed GRAS dossiers for the use of nutritional substances such as carotenoids, fatty acids, and proteins in foods.

Developed gap assessments to identify data needs necessary to fill prior to development of a GRAS dossier.
