Dr. Oldewage-Theron's research interests include household food insecurity and malnutrition in resource-poor communities in Africa. During the last fifteen years, she has investigated the effect of various interventions, including food fortification, agriculture and horticulture, dietary diversity, supplementation, nutrition education, food product development and implementation, as well as school feeding programs on poverty, food insecurity and nutritional status of women,  children and the elderly by applying scientific principles. Her community research and development program at present is mainly focused on soy applications and the nutritional benefits of soy for human health in South Africa.
