Passionate about Nutrition, Dr. Lama Mattar pursued her BSc and MSc in nutritional sciences at the American University of Beirut. She also completed a PhD specialized in eating disorders and behaviors at University of Pierre & Marie-Curie in Paris, France (2011). 

Dr. Mattar believes that nutrition is the cornerstone of the medical therapy for many diseases. This belief in the therapeutic aspect of nutrition made her practice clinical dietetics in various specialized units in the USA, Switzerland, Lebanon and France.

She loves teaching and research. Dr. Mattar taught graduate and undergraduate nutrition courses at the American University of Beirut and is now assistant professor at the Lebanese American University.

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. 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 of children in elementary public schools, and she is involved in breastfeeding awareness campaigns.
