Quick Answer
Store food for 5 years using MREs, for 10 years with dehydrated foods and Mylar bags, and for 20 years with freeze-dried meals and sealed containers.
Short-Term Storage for 5 Years
For a 5-year food supply, consider using Meals Ready to Eat (MREs). These pre-cooked, pre-packaged meals can be stored at room temperature and require no refrigeration. A 5-year supply would require 1,800-2,400 MREs, depending on individual caloric needs.
Longer-Term Storage for 10 and 20 Years
For longer-term storage, dehydrated foods and Mylar bags are a cost-effective option. Dehydrate foods such as fruits, vegetables, and meats, then store them in Mylar bags with oxygen absorbers to remove moisture. This method can store food for 10-15 years. For 20-year storage, consider using freeze-dried meals. Freeze-drying removes 98% of moisture, making it ideal for long-term storage. Store freeze-dried meals in sealed, airtight containers, such as #10 cans or glass jars with tight-fitting lids.
