Biography Dr. Paul F. Jacques is Senior Scientist and Director of the Nutritional Epidemiology Program at the HNRCA. His research interests include B vitamins, whole grains, flavonoids, hydration, diet patterns and diet quality, and their relation to maintenance of metabolic, cognitive and physical function with aging. Dr. Jacques has published more than 300 peer-reviewed manuscripts of original research over his career and has made many important discoveries in the field of nutritional epidemiology. Among his most significant research accomplishments, Dr. Jacques observed that institution of mandated folic acid fortification in the United States had a profound impact on folate status of older Americans, including possible adverse health effects of high levels of folic acid consumption. He demonstrated that fortification increased circulating unmetabolized folic acid concentrations and that the presence of detectable circulating unmetabolized folic acid among older Americans with inadequate vitamin B12 status was related to lower cognitive test scores. Dr. Jacques also demonstrated that higher choline intake is related to better cognitive performance and brain aging. His current research includes longitudinal studies of protein intake and hydration on healthy aging. He is a professor at the Friedman School of Nutrition Science and Policy. Dr. Jacques has given over 100 invited presentations across the world and has served on numerous grant review panels. He is a member of the Society for Epidemiologic Research and American Society for Nutrition and is a fellow in the American College of Nutrition.
