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.
