Dehydrating food is cost-effective effective and rewarding. Using a dehydrator prepares foods for snacking or storage while taking minimal effort. Cooking, canning or freezing preserves food. But, the process often depletes vital nutrients. On the other hand, by dehydrating food sufficiently, the nutritional value remains. Dried fruits and vegetables provide an abundance of fiber along with vitamins A and C. Dehydrated produce is also a good source of a variety of vital minerals including magnesium, potassium and selenium.
