The number one survival food is undoubtedly dried beans. Dried beans are an excellent source of protein, fiber, and essential vitamins and minerals. They are also incredibly versatile - they can be cooked in a variety of ways to make delicious meals or snacks. Beans have a long shelf life when stored properly, making them ideal for emergency situations where access to fresh food may be limited. Furthermore, they are relatively inexpensive compared to other sources of nutrition such as meat or fish. For these reasons, dried beans should always be part of any emergency food supply kit.
