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.

When university presidents were surveyed in spring of 2020 about what they felt were the most pressing concerns of COVID-19, college students going hungry didn't rank very high.
Why It Matters<p>This is not just a matter of growling stomachs. This is a straight-up education and health issue.</p><p>When students don't really know if they'll be able to get enough to eat, it can lead to a series of problems that make it harder to stay in school. For instance, it can affect <a href="https://doi.org/10.1177%2F1359105318783028" target="_blank">academic performance</a> and <a href="https://doi.org/10.1186/s12889-019-6943-6" target="_blank" rel="noopener noreferrer">sleep quality</a>. It can also lead to <a href="https://doi.org/10.1177/1359105318783028" target="_blank" rel="noopener noreferrer">poor mental and physical health</a> outcomes for college students.</p><p>Food insecurity can also result in disrupted eating patterns if there is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6627945/" target="_blank" rel="noopener noreferrer">not enough food or the variety</a> or <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-019-6943-6" target="_blank" rel="noopener noreferrer">quality of what someone eats</a> is low.</p>
Campus Food Pantries<p>Previous strategies by <a href="https://www.gao.gov/assets/700/696254.pdf" target="_blank">colleges and universities</a> to fight hunger in their student bodies have varied widely. They include campus food pantries, emergency cash assistance and nutrition education through noncredit classes or workshopse.</p><p>These strategies were put to the test during the spring 2020 semester, when nearly <a href="https://hope4college.com/wp-content/uploads/2020/06/Hopecenter_RealCollegeDuringthePandemic.pdf" target="_blank">three in five students</a> said they had trouble meeting their own basic needs during the pandemic.</p><p>College food pantries saw <a href="https://www.utrgv.edu/newsroom/2020/05/01-utrgv-student-food-pantry-seeing-recent-increase-in-demand-during-covid-19.htm" target="_blank" rel="noopener noreferrer">big increases</a> in demand. Others said they <a href="https://www.theprospectordaily.com/2020/09/22/uteps-food-pantry-is-running-out-of-food/" target="_blank" rel="noopener noreferrer">were getting less donated food</a>. This made it even harder to meet the rising food needs of students.</p><p>Campus food pantries largely rely on local or regional food banks, which have been dealing with <a href="https://www.indystar.com/story/news/local/2020/10/04/indiana-food-banks-call-more-food-stamps-meet-publics-need/3523683001/" target="_blank" rel="noopener noreferrer">greater demand</a> than they are able to meet during the pandemic.</p><p>The many students who are attending college remotely will, of course, have less access to campus resources like food pantries.</p>
Federal Help<p>Other potential ways to get more food are government programs like the <a href="https://www.fns.usda.gov/snap/recipient/eligibility" target="_blank">Supplemental Nutrition Assistance Program</a>, known as SNAP. Yet the majority of able-bodied students are not eligible. Long-standing restrictions, like the <a href="https://www.fns.usda.gov/snap/students" target="_blank">college SNAP rule</a>, prevent full-time students from receiving these benefits.</p><p>Such regulatory hurdles were created under the assumption that most students can rely on their parents to get enough to eat. However, college students have vastly different levels of financial support. Some students can rely on their parents for everything and others cannot rely on their parents for anything.</p><p>Decreased reliance on parental financial support is <a href="https://ir.library.louisville.edu/jsfa/vol47/iss3/5/" target="_blank">especially common</a> for first-generation students and students of color, who now make up <a href="https://1xfsu31b52d33idlp13twtos-wpengine.netdna-ssl.com/wp-content/uploads/2019/02/Race-and-Ethnicity-in-Higher-Education.pdf" target="_blank" rel="noopener noreferrer">45% of enrolled college students</a>.</p><p>Under normal circumstances, many college students might rely on part-time jobs to pay for their food.</p>
Short-Term Solutions<p>Universities and colleges can make it a priority to ensure students are aware of all available campus resources and services. They can also potentially help students apply for federal assistance benefits.</p><p>Campus food pantries are not a fully effective and efficacious solution for the scale of college food insecurity, but they can be a good interim solution to increase access to food for students.</p><p>Campuses without food pantries can start one, making use of resources the <a href="https://cufba.org/resources/" target="_blank">College and University Food Bank Alliance</a> provides. Schools with food pantries can try to get them to <a href="https://www.swipehunger.org/5campuspantry/" target="_blank" rel="noopener noreferrer">reach more students</a>.</p><p>Universities and colleges can also lean on one another for support. The <a href="http://wp.auburn.edu/endchildhungeral/alabama-campus-coalition-for-basic-needs/" target="_blank" rel="noopener noreferrer">Alabama Campus Coalition for Basic Needs</a> is a great example of this. It brings together 10 universities across the state of Alabama collectively working to address student food insecurity.</p>

Plain Naturals offers a 5000mg CBD oil tincture in 30ml bottle for $99.99.<p>Consumers have gotten used to paying high prices for low amounts of cannabidiol.

Of all the plastic we've ever produced, only 9% has been recycled. So what happened to all that plastic you've put in the recycling bin over the years?
Triangle of Mistruths<p>The myth created around plastic recycling has been one of simplicity. We look for the familiar triangle arrows, then pop the waste in the recycling bin so it can be reused.</p><p>But the true purpose of those triangles has been misunderstood by the general public ever since their invention in the 1980s.</p><p>These triangles were actually created by the plastics industry and, according to a report provided to them in July 1993, <a href="https://www.npr.org/transcripts/912150085" target="_blank">were creating "unrealistic expectations"</a> about what could be recycled. But they decided to keep using the codes.</p><p>Which is why many people still believe that these triangular symbols (also known as a <a href="https://sustainablepackaging.org/101-resin-identification-codes/" target="_blank" rel="noopener noreferrer">resin identifier code</a> or RIC) means something is recyclable.</p><p>But according to the American Society for Testing and Materials International (ASTM) – which controls the RIC system – the numbered triangles "<a href="https://www.astm.org/Standards/D7611.htm" target="_blank" rel="noopener noreferrer">are not recycle codes</a>." In fact, they weren't created for the general public at all. They were made for the post-consumer plastic industry.</p><p>In other words, the symbols make it easier to sort the different types of plastics, some of which cannot be recycled – <a href="https://www.ecobin.com.au/understand-recycling-codes/" target="_blank" rel="noopener noreferrer">depending on the recycling facility</a>.</p><p>"Unfortunately, just placing your plastic into the recycling bin doesn't mean it will get recycled," says Lara Camilla Pinho. She is an architect and lecturer at the UWA School of Design who is researching novel uses of plastic waste.</p><p>"The recycling system is complicated and often dictated by market demand. Not all plastic is recyclable. We cannot recycle plastic bags or straws for example."</p>
Behind the Scenes<p>So, what makes recycling plastics so difficult?</p><p>"Essentially, there are two types of plastics – thermoplastics and thermosets. While thermoplastics can be re-melted and re-molded, thermosets contain cross-linked polymers that cannot be separated meaning they cannot be recycled," says Lara.</p><p>"Even thermoplastics have a limit to the amount of times we can recycle them, as each time they are recycled they downgrade in quality."</p><p>Even when plastics are recyclable, it is <a href="https://www.theguardian.com/environment/2019/oct/13/war-on-plastic-waste-faces-setback-as-cost-of-recycled-material-soars" target="_blank">often more costly</a> than simply making new plastics.</p>
Sugar, Seaweed and Mushrooms<p>If the conventional recycling system isn't working, what else can we do with all the plastic we've created?</p><p>Lara is looking for ways to add value to recycled plastics such as using it in the design and development of architectural products. She hopes to use these architectural products to help underserved communities that are disproportionately affected by plastic waste.</p><p>In addition to recycling, we also need to find ways to reduce our use of virgin petroleum-based plastics.</p><p>Bioplastic is one such product that has been getting a lot of hype over the last few years. And although they're better than petroleum-based plastics, bioplastics also come with their own <a href="https://phys.org/news/2017-12-truth-bioplastics.html" target="_blank">set of challenges</a>.</p><p>"There are already a lot of bio-based alternatives to plastic, such as bagasse – a byproduct of sugar cane processing," says Lara.</p><p><a href="https://blogs.scientificamerican.com/observations/the-mycelium-revolution-is-upon-us/" target="_blank" rel="noopener noreferrer">Mycelium</a>, a type of fungi we most often associate with mushrooms, are also providing an interesting plastic alternative.</p><p>"In the field of architecture, mycelium is starting to be used as an alternative to plastic insulation, but also as compostable packaging and bricks," says Lara.</p><p>"The bricks take around five days to make and are strong, durable, water resistant and compostable at the end of their use."</p><p><a href="https://www.arup.com/news-and-events/hyfi-reinvents-the-brick" target="_blank" rel="noopener noreferrer">Hy-Fi Tower</a>, created by <a href="http://www.thelivingnewyork.com/living_about.html" target="_blank" rel="noopener noreferrer">The Living</a>, is an example of a building made from these bricks.</p><p>And finally, there's seaweed.</p><p>"[Seaweed is] cheap and can reproduce itself quickly without fertilizers. In architecture, there is use for seaweed as an alternative to plastic insulation but also as cladding," says Lara.</p>
More Money, More Problems<p>While all these alternatives are great, the main cause of our plastic dilemma is not scientific or technological, but economic.</p><p>As long as it remains <a href="https://engineering.mit.edu/engage/ask-an-engineer/why-is-it-cheaper-to-make-new-plastic-bottles-than-to-recycle-old-ones/" target="_blank">cheaper to create new plastics</a> from fossil fuels rather than from bioplastics or from recycling, we're going to be stuck with plastic garbage islands floating in our oceans.</p><p>The true cost to our health and our environment has yet to be included in the equation. But once it is, maybe that is when the real shift will happen.</p>
