With freeze dried foods you can get a good selection of nutritionally balanced foods and they are easy to carry, even if you have to bug out. They have a very long shelf-life of up to 25 years. The only drawback is if you don’t have water, you can’t rehydrate your food. Plus, it is ideal to have warm water so you can have a warm meal, so if there is no way to heat your water, then you will be eating a cold meal.
Hopefully, you will never have to use it, but you should have it. A self-defense weapon is a critical part of your prepper gear. Sometimes, just showing it is enough to deter people. Obviously, a firearm is the best choice. But there are other options, such as a crossbow or longbow with arrows, a taser, or a knife. Whatever you choose, be sure you are well-trained and practiced and that you have plenty of ammo.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
