Dry foods are items that have had most of their moisture removed, which helps to preserve them for longer periods. Common examples include dried fruits, nuts, grains, and pasta. These foods are often lightweight and easy to store, making them popular for camping, hiking, and emergency supplies. The drying process can involve methods like air drying, freeze-drying, or dehydrating. Because they contain less water, dry foods typically have a longer shelf life compared to fresh foods. They can also be more nutrient-dense, as the concentration of vitamins and minerals increases when moisture is removed.
