The four pillars of food security are availability, accessibility, utilization, and stability. Availability means with having enough food available. Accessibility deals with having the economic and physical means to access food. Utilizations refers to using and handing food in a safe in proper manner so as to fulfill the requirements of nutrition, hygiene, and health. Stability is defined as having steady, consistent access to food. True food security cannot be reached unless all four pillars are fulfilled. Therefore, fighting food insecurity means understanding and contributing to all four pillars.
