Dr. Sahyoun’s current research focuses on examining the relationship between diet and lifestyle factors on the nutrition status and health outcomes of vulnerable populations such as older adults. She is also studying the role of nutrition in the transition of care from hospital back to community living. Internationally, Dr. Sahyoun with colleagues from the American University of Beirut, Lebanon and US Department of Agriculture developed and validated the Arab Family Food Security Scale. Dr. Sahyoun is involved in several projects assessing the status of food security and its determinants among vulnerable populations in the Middle East and sub-saharan Africa.
