Your first-line defense against hunger and its associated consequences, these survival rations and bars are convenient, highly nutritious, and easily prepared in the event of a real emergency. Even though the human body can (depending on many factors), survive without food for potentially weeks, food gives you the energy and psychological uplift to get you through. Always know that access to (potable) water is a factor in your survival planning as to whether to consume calories or not due to the potential dehydrating effects of consumption without adequate water resources. Bearing that in mind, your food strategy needs to go hand-in-hand with your water collection & purification strategy to truly amplify your survival metrics.
