Cross-Cultural Nutrition, Drug-Nutrient Interactions


Dr. Marcia Magnus has been an associate professor in the Department of Dietetics and Nutrition at FIU since 1991. Formerly, she was a public health nutritionist at the United Nations Caribbean Food and Nutrition Institute, which offered technical assistance in nutrition to 21 Caribbean countries. As a UN consultant, she developed the Nutrition Plans of Action for Monserrat, Dominica, and the Bahamas; and conducted training for practicing nutrition professionals. Her research focuses on cross-cultural nutrition, readability of nutrition education materials, weight perception, barbershop nutrition education and drug-nutrient interactions. Dr. Magnus has traveled to more than 50 countries and this provides the basis for her specialization in cross-cultural nutrition competence.
