Fruits, vegetables, soups, and even canned meats will last one to five years. Usually, with an expiration date of a few years in the future, canned food will last even longer in your underground bunker. Everything from canned pineapples to pork will stay fresh for a while. Theoretically, you can survive on canned food alone because of advances in canning technology in terms of sanitation and variety.
However, food should be as nutritious as possible to give your body all the necessary vitamins and minerals it needs to stay healthy. They are excellent sources of protein. Just try to buy fish packed in water instead of oil. That will cause it to have a much lower sodium content.
Canned tuna and salmon aren't just for sandwiches, Perry added. You can put this fish on top of a salad or eat it with whole wheat crackers. Seriously speaking, soup is the best thing when you're sick. But it can also be great for when the living dead take over the power company and all the fresh food in the supermarket rots.
The variety of canned soups that exist offers many proteins, carbohydrates and vitamins needed to stay healthy while civilization as we know it disappears. You're not going to die of scurvy on my shift. Canned fruits such as tangerines, apricot halves, and even that incomplete “fruit cocktail” provide a wealth of nutrients, such as vitamin C and potassium, that will set you up to defend yourself against zombies and the common cold. While it's not high in nutritional density, it's high in adorability.
I'm not being cheesy when I say it's a good canned food. Okay, that was pretty bad, but come on, tender corn tastes good enough to make up for any terrible pun intended. Before you rush out to the store, here are a few things to think about when it comes to preparing canned food. If your emergency food supply requires water, be sure to carry additional water in your emergency food supplies (other than drinking water, which is most important of all), so that you have enough to reconstitute food and still have enough to hydrate.
This large can of vegetable stew contains a staggering 40 servings, so you'll be well-fed if you have it in your emergency supplies. Although canned foods are quite infamous and known to be the opposite of nutritious ones, certain exemptions should be on your list when you go to the grocery store. You don't want to have to restock your emergency food supplies annually, so it's worth checking how long your supplies will last. Mark your food supplies with the date they were stocked, so that years later, you can check them and restock them if needed.
So to help you all, I've compiled a list of the best canned foods for surviving the apocalypse, ranked by nutritional density, flavor and palatability in canned form.
