A Humanitarian Daily Ration (HDR) is a type of food package designed to provide essential nutrition to individuals in emergency situations, such as natural disasters or conflicts. Each ration is carefully balanced to meet the daily dietary needs of an adult, ensuring that it contains adequate calories, proteins, vitamins, and minerals. HDRs are typically packaged for easy distribution and consumption, often requiring no cooking or preparation. They are used by various humanitarian organizations, including the United Nations and Red Cross, to support displaced populations and those affected by crises around the world.
