The only food that does not spoil is honey. Honey can last for thousands of years without spoiling because it contains low levels of moisture and high levels of sugar, which means it doesn't provide a suitable environment for bacteria or other microorganisms to grow. Additionally, bees add an enzyme called glucose oxidase to the nectar they collect, which produces hydrogen peroxide when honey is diluted with water, further inhibiting the growth of bacteria. Therefore, honey is an excellent option for long-term storage and can be a valuable source of food for survivalists or preppers.
