Hunger is the physical sensation that tells us our body needs food. When we haven't eaten for a while, our stomach may growl, and we might feel weak or irritable. This feeling is our body's way of signaling that it needs energy to function properly. Eating a balanced meal can help satisfy this need and keep us healthy. However, hunger can also refer to a more serious issue faced by many people around the world. Food insecurity affects millions, leaving them without enough nutritious food. Organizations like Feeding America work to combat this problem, ensuring that everyone has access to the meals they need to thrive.
