Research Interests and Projects

Understanding nutritional behaviors, attitudes and practices of humans is a pressing need, in light of the alarming increase in the prevalence of nutrition-related health problems in the Middle East in the last three decades. Dr. Mattar’s research contributes to understanding and preventing various detrimental health problems at an individual and communal level. It proposes policies and community interventions at a grass-root level. She has been invited as guest speaker to several international conferences, and publishes extensively in high impact factor peer-reviewed journals.

In addition, Dr. Mattar is heavily involved in community-related projects where she puts her expertise in nutrition and education at the service of the community as she believes in establishing stronger and more sustainable outreach activities for our graduates.

She attracted grants from UN agencies for community interventions, she is the official nutritionist of the Beirut Marathon Association, she developed and implemented with MMKN-NGO a full program for health and nutrition education in elementary public schools, and she is involved in breastfeeding awareness campaigns.
