Non-perishable foods, such as canned goods and dried fruit, have a long shelf life and don't require refrigeration to keep them from spoiling. Instead, they can be stored at room temperature, such as in a pantry or cabinet.
They're not only standard kitchen items but also favored by backpackers and campers who can't bring perishable foods like fresh meats, dairy, and vegetables on the trail.
What's more, non-perishable goods are essential in emergency situations and favored by charitable organizations that feed or give groceries to people facing homelessness or food insecurity.
Although some items like boxed macaroni and cheese are packed with preservatives and other unhealthy ingredients, quite a few nutritious non-perishable foods are available.
Here are 12 of the healthiest non-perishable foods.
1. Dried and Canned Beans
With a long shelf life and high nutrient content, dried and canned beans are smart non-perishable food choices. Canned beans can be kept at room temperature for 2–5 years while dried beans can last 10 or more years, depending on the packaging.
In fact, one study found that pinto beans stored up to 30 years were considered edible by 80% of people on an emergency food use panel.
Beans are an excellent source of fiber, plant-based protein, magnesium, B vitamins, manganese, iron, phosphorus, zinc, and copper. What's more, they pair well with most foods and make hearty additions to soups, grain dishes, and salads.
2. Nut Butters
Nut butters are creamy, nutrient-dense, and delicious.
Although storage temperatures can affect shelf life, commercial peanut butter keeps for up to 9 months at room temperature. Natural peanut butter, which does not contain preservatives, lasts up to 3 months at 50℉ (10℃) and only 1 month at 77℉ (25℃).
Nut butters are a rich source of healthy fats, protein, vitamins, minerals, and powerful plant compounds, including phenolic antioxidants, which are compounds that protect your body against oxidative stress and damage by unstable molecules called free radicals.
Jars of nut butter can be stored in your pantry while smaller packets can be taken backpacking or camping for an on-the-go snack.
3. Dried Fruits and Vegetables
Although most fresh fruits and vegetables have a short shelf life, dried produce is considered non-perishable. When properly stored, most dried fruit can be safely kept at room temperature for up to 1 year, and dried vegetables can be kept about half that time.
You can choose from a variety of dried fruits and vegetables, including dried berries, apples, tomatoes, and carrots. You can also use a dehydrator or oven to make your own dried fruits and vegetables. Vacuum-sealed packaging can help prevent spoilage.
Dried fruits and veggies can be enjoyed as a snack or added to trail mix. Plus, dried veggies can be rehydrated by adding them to soups or stews if fresh produce isn't available.
4. Canned Fish and Poultry
Although fresh fish and poultry are packed with nutrients, they're highly perishable. All the same, canned varieties can be safely kept without refrigeration for long periods — up to 5 years at room temperature.
Tuna and other seafood products are also sold in lightweight packages known as retort pouches, which are perfect for smaller pantries and backpacking. Seafood in retort pouches has a shelf life of up to 18 months.
Chicken and other meats can be found in retort pouches as well, though you should refer to the packaging for shelf life information.
5. Nuts and Seeds
Nuts and seeds are portable, nutrient-dense, and shelf-stable, making them non-perishable food staples. Favored by backpackers and hikers for high calorie snacking, they're also great to have on hand in any situation.
On average, nuts last about 4 months when kept at or near room temperature (68℉ or 20℃), though shelf life varies greatly between nut varieties.
For example, cashews can be kept for 6 months at 68℉ (20℃) while pistachios only last 1 month at the same temperature.
Seeds have comparable shelf lives. According to the USDA, pumpkin seeds stay fresh for 6 months at room temperature.
Whole grains like oats, rice, and barley have a much longer shelf life than other popular but perishable carb sources like bread, making them a smart choice for long-term food storage.
For example, brown rice can be kept at 50–70℉ (10–21℃) for up to 3 months while farro lasts up to 6 months at room temperature.
Grains can be added to soups, salads, and casseroles, making them a versatile non-perishable ingredient. Plus, eating whole grains may reduce your risk of type 2 diabetes, heart disease, and certain cancers.
7. Canned Vegetables and Fruits
Canning has long been used to lengthen the shelf life of perishable foods, including fruits and vegetables.
The heat used during canning kills potentially harmful microorganisms, and the characteristic seal of canned foods keeps new bacteria from spoiling the contents.
The shelf life of canned fruits and vegetables depends on the type of produce.
On the other hand, high-acid fruits like grapefruit, apples, peaches, berries, and pineapple last just 12–18 months. The same goes for vegetables packed in vinegar, such as sauerkraut, German potato salad, and other pickled vegetables.
When shopping, choose canned fruits packed in water or 100% fruit juice rather than heavy syrup, and opt for low sodium canned veggies whenever possible.
If you're crafty in the kitchen, consider canning at home using store-bought or garden-grown vegetables and fruits. If you don't know how, you can consult numerous books or online tutorials.
Meat preservation is a practice used since ancient times to keep protein sources from spoiling. Specifically, jerky is made by curing meat in a salt solution, then dehydrating it. Preservatives, flavorings, and other additives are sometimes used during processing.
Many types of jerky are available, including beef, salmon, chicken, and buffalo. There are even plant-based jerky alternatives made from coconut, banana, and jackfruit. That said, note that these alternatives are not nutritionally equivalent to meat-based jerkies.
Any kind of jerky can be enjoyed in moderation, but the healthiest options are those that don't contain added sugar, artificial flavors, or preservatives.
9. Granola and Protein Bars
Granola and protein bars are a go-to food for backpackers and hikers thanks to their long shelf life and nutrient composition.
Many granola bars stay fresh for up to 1 year at room temperature. Likewise, most protein bars have a shelf life of at least 1 year, though it's best to check the label on individual products for expiration information.
What's more, granola and protein bars can be highly nutritious as long as you choose the right kinds. Look for brands that are full of hearty ingredients, such as oats, nuts, and dried fruit, and contain minimal added sugars and artificial ingredients.
Canned and dried soups are an excellent choice when stocking your pantry. They're also preferred by food donation organizations.
Most canned soups are low in acid and can last up to 5 years at room temperature. The exception is tomato-based varieties, which have a shelf life of about 18 months.
Although most dried soup mixes should last up to 1 year in storage, it's best to check labels for expiration dates.
Choose soups that are rich in healthy ingredients like vegetables and beans, and select low sodium products whenever possible, as consuming too much added salt may harm your health.
11. Freeze Dried Meals
Freeze drying uses sublimation, a process in which ice is converted directly into vapor, to remove water from food so that it lasts longer at room temperature. Freeze dried meals are popular among backpackers because of their light weight and portability.
12. Shelf-Stable Milk and Nondairy Milk
While fresh milk and some nondairy alternatives like almond and coconut milks have to be refrigerated, shelf-stable milk and many nondairy milks are made to keep at room temperature.
Shelf-stable or aseptic milk is processed and packaged differently than regular milk because it's heated to higher temperatures and packed in sterile containers.
One study found that shelf-stable milk had a shelf life of up to 9 months when kept at 40–68℉ (4–20℃).
Plant-based drinks like soy milk packaged in flexible materials, including plastic, paper, and aluminum, similarly last up to 10 months, while canned coconut milk keeps up to 5 years at room temperature.
Shelf-stable and plant-based milks can be used when refrigeration isn't available. Powdered milk is a good alternative, with an estimated shelf life of 3–5 years when kept in a cool, dark place. It can be reconstituted with clean water in small portions as needed.
The Bottom Line
Non-perishable foods last a long time without spoiling and are necessary for numerous situations.
Whether you want to donate items to charitable organizations, prepare for potential emergencies, purchase backpacking-friendly products, or merely stock your pantry, you can choose from an abundance of healthy foods that don't require refrigeration.

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>
Cutting Off Circulation<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>
The Atlantic Meridional Overturning Circulation has a major effect on the climate. Praetorius (2018)
Is it Time to Declare a Climate Emergency?<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>
