9 Foods That Are Just As Good Frozen As Fresh

Have you browsed the frozen food aisle recently? When it comes to food, many health-conscious shoppers are spending more time than ever looking for organic, farm-to-table ingredients. But if you don’t have a farmer’s market down the block, fear not—frozen foods are usually more convenient than the fresh equivalent, and in some cases can even be healthier!

How can frozen foods be better than fresh? The biggest factor is time. Eating raspberries right off the bush, for instance, is a best-case scenario, but the berries you buy from your local grocery store may have spent several days being shipped, stored, and possibly bruised by the time they reach shelves. As food ages, nutrients and vitamins are lost.

Furthermore, the demands of transportation necessitate that grocery store produce is often picked well before reaching ideal ripeness. But frozen foods can be harvested at their best, then immediately flash-frozen to retain their nutritional content. In other cases, freezer options are simply a more convenient way to save time and money. If you're looking to restock your freezer, or just want to know which foods offer the best bang for your limited freezer space, read on.

1. BROCCOLI

Today’s food scientists agree that in nearly all cases, frozen fruits and vegetables are just as nutritious as their fresh counterparts, and in some cases, the frozen varieties even pack an extra-healthy punch. In a study conducted at the University of California, Davis, Dr. Ali Bouzari and her team discovered that the process of blanching and freezing broccoli florets actually results in a higher level of riboflavin (an essential B vitamin that helps with energy production). Not to mention you’ll save space and weight in your grocery bag by passing on bulky broccoli stalks!

2. HASH BROWNS

Although fruits and vegetables are some of the easiest and most common choices, don’t forget that prepared foods and more complex dishes can be stored in the freezer as well. In fact, celebrity chef Billy Parisi tells Parade magazine that "the surest bet you’ll find in my kitchen is a well-stocked freezer." In addition to more expected fare like peas and chicken breasts, Parisi’s a fan of using frozen hash browns to get a jump on a big weekend family breakfast. "I love to simply sear frozen hash browns in a little olive oil seasoned with salt and pepper and serve it as a side," he says, or he suggests adding in scrambled eggs, bacon, peppers, and onions for a hearty hash.

3. SHRIMP

Freezing seafood can be intimidating—not all species of fish freeze effectively, and various types of shellfish require different procedures to safely freeze, thaw, and prepare. Frozen shrimp, however, are a staggeringly easy back-of-the-freezer secret weapon, and they can last 6-8 months in the reserves. Keep an eye out for brands which advertise "IQF" ("Individually Quick Frozen"), a process which ensures the meat will retain better flavor and texture after thawing. Next time surprise guests arrive before dinner, just add pre-cleaned shrimp to fill out a stew, salad, or pasta. Take a look at The City Cook’s primer for even more tips to make the most of your marine morsels.

4. BLUEBERRIES

Blueberries boast an amazing blend of antioxidants, phytoflavinoids, potassium, and vitamins—they’re a legitimate "superfood" and can help fight inflammation and reduce the risk of cancer and heart disease. Fresh berries are divine, but according to the Environmental Working Group, blueberries are also one of the fruits most likely to carry a high pesticide content (they were listed as #14 of 48 in 2016). Frozen blueberries are just as convenient, and according to Livestrong.com, contain less than half the insecticides of fresh berries. They'll last longer frozen and are just as easy to toss in warm oatmeal or a smoothie for an invigorating start to your day.

5. CHILI

Speaking of time-saving measures, some foods lend themselves to freezing simply by virtue of scale. Take chili, for instance—most recipes (even the weird ones) take several hours to prepare and yield 6-8 servings, if not more. That works out great for Super Bowl Sunday, but it's a bit impractical for a Tuesday night dinner for two. Fortunately, frozen chili retains its rib-sticking appeal for 4-6 months, but remains safe even past that. So, if you make a huge pot over the weekend, you can enjoy re-heating bowls of unbelievably easy comfort food for weeks on end.

6. FRESH HERBS

Incorporating fresh herbs (ideally from your own backyard) is one of the most enjoyable elements of summertime cooking. The end of warm weather, however, provides an excellent opportunity to employ another strategic freezer move. Dice the herbs—anything from basil, parsley, dill, cilantro, oregano, mint, etc.—then coat them with olive oil before freezing in ice cube trays or Ziploc bags. (There’s some debate about the best method; Serious Eats compared several possibilities for the scientifically curious.) When winter rolls around, you can pop a flavorful herb-cube right into your favorite sauce or soup.

7. CORN

Corn is another vegetable that Dr. Bouzari found to have a nutritional net benefit after the industrial flash-freezing process—her study found the frozen sample had higher levels of vitamin C than fresh corn, and no significant difference in fiber or mineral content. Even putting nutrition aside, however, frozen corn deserves a place on this list solely for ease of preparation. Simply thawing corn to toss into a burrito or casserole saves lots of time and hassle.

8. PIZZA

You might be hard-pressed to find anyone who argues for the superiority of hastily made frozen pizza over a hot, fresh pie out of a wood oven. But with some insider knowledge, it’s easier than ever to give your local pizzeria some competition. Bon Appétit's Adam Rapoport advises starting with Roberta’s frozen pizza, then ramping it up with thin slices of red onion, sea salt, and a drizzle of quality olive oil before baking. Here, four other chefs suggest similar specialty-ingredient improvements, from pickled pepperoncinis to grated Indian Amul cheese.

9. GIRL SCOUT COOKIES

The year's batch of Girl Scout Cookies are currently being distributed, and typically, most boxes don’t last very long. But for those with the foresight to buy extra (and the discipline to not eat them all immediately), popping a box or two in the freezer until the summer months can make for a delightfully cool snack on a sweltering day. Plus, saving some Thin Mints for a sweet, boozy chocolate-mint milkshake is the perfect way to reward your patience.

Stop Your Snoring and Track Your Sleep With a Wi-Fi Smart Pillow
REM-Fit
REM-Fit

Everyone could use a better night's rest. The CDC says that only 66 percent of American adults get as much sleep as they should, so if you're spending plenty of time in bed but mostly tossing and turning (or trying to block out your partner's snores), it may be time to smarten up your sleep accessories. As TechCrunch reports, the ZEEQ Smart Pillow improves your sleeping schedule in a multitude of ways, whether you're looking to quiet your snores or need a soothing lullaby to rock you to sleep.

After a successful Kickstarter in 2016, the product is now on sale and ready to get you snoozing. If you're a snorer, the pillow has a microphone designed to listen to the sound of your snores and softly vibrate so that you shift positions to a quieter pose. Accelerometers in the pillow let the sleep tracker know how much you're moving around at night, allowing it to record your sleep stages. Then, you can hook the pillow up to your Amazon Echo or Google Home so that you can have your favorite smart assistant read out the pillow's analysis of your sleep quality and snoring levels the next morning.

The pillow is also equipped with eight different wireless speakers that turn it into an extra-personal musical experience. You can listen to soothing music while you fall asleep, either connecting the pillow to your Spotify or Apple Music account on your phone via Bluetooth or using the built-in relaxation programs. You can even use it to listen to podcasts without disturbing your partner. You can set a timer to turn the music off after a certain period so you don't wake up in the middle of the night still listening to Serial.

And when it's time to wake up, the pillow will analyze your movements to wake you during your lightest sleep stage, again keeping the noise of an alarm from disturbing your partner.

The downside? Suddenly your pillow is just another device with a battery that needs to charge. And forget about using it in a place without Wi-Fi.

The ZEEQ Smart Pillow currently costs $200.

15 Reasons You Should Appreciate Squirrels

Even if you live in a big city, you probably see wildlife on a regular basis. Namely, you're sure to run into a lot of squirrels, even in the densest urban areas. And if you happen to live on a college campus, well, you're probably overrun with them. While some people might view them as adorable, others see them as persistent pests bent on chewing on and nesting in everything in sight. But in honor of National Squirrel Appreciation Day, here are 15 reasons you should appreciate the savvy, amazing, bushy-tailed critters.

1. THEY CAN JUMP REALLY, REALLY FAR.

In one study [PDF] of the tree-dwelling plantain squirrels that roam the campus of the National University of Singapore, squirrels were observed jumping almost 10 feet at a stretch. In another study with the eastern ground squirrel, one researcher observed a squirrel jumping more than 8 feet between a tree stump and a feeding platform, propelling itself 10 times the length of its body. Flying squirrels, obviously, can traverse much farther distances midair—the northern flying squirrel, for instance, can glide up to 295 feet [PDF].

2. THEY'RE VERY ORGANIZED …

In fact, they may be more organized than you are. A recent study found that eastern fox squirrels living on UC Berkeley's campus cache their nuts according to type. When given a mixture of walnuts, pecans, almonds, and hazelnuts, the squirrels took the time to hide each type of nut in a specific place. This method of "spatial chunking" may help them remember where the nuts are when they go to retrieve them later. Though the study wasn't able to determine this for sure, the study's results suggested that the squirrels may have been organizing their caches by even more subtle categories, like the size of the nuts.

3. … BUT THEIR FORGETFULNESS HELPS TREES GROW.

Tree squirrels are one of the most important animals around when it comes to planting forests. Though they may be careful about where they bury their acorns and other nuts, they still forget about quite a few of their caches (or at least neglect to retrieve them). When they do, those acorns often sprout, resulting in more trees—and eventually, yet more acorns for the squirrels.

4. THEY HELP TRUFFLES THRIVE.

The squirrel digestive system also plays an important role in the survival of truffles. While above-ground mushrooms can spread their spores through the air, truffles grow below ground. Instead of relying on the air, they depend on hungry animals like squirrels to spread their spores to host plants elsewhere. The northern flying squirrel, found in forests across North America, depends largely on the buried fungi to make up its diet, and plays a major role in truffle propagation. The squirrels poop out the spores unharmed on the forest floor, allowing the fungi to take hold and form a symbiotic relationship with the tree roots it's dropped near.

5. THEY'RE ONE OF THE FEW MAMMALS THAT CAN SPRINT DOWN A TREE HEAD-FIRST.

You may not be too impressed when you see a squirrel running down a tree, but they're actually accomplishing a major feat. Most animals can't climb vertically down head-first, but squirrel's back ankles can rotate 180°, turning their paws all the way around to grip the tree trunk as they descend.

6. SEVERAL TOWNS COMPETE FOR THE TITLE OF 'HOME OF THE WHITE SQUIRREL.'

Squirrels are a more popular town mascot than you might think. Surprisingly, more than one town wants to be known as the "home of the white squirrel," including Kenton, Tennessee; Marionville, Missouri; the Canadian city of Exeter, Ontario; and Brevard, North Carolina, the location of the annual White Squirrel Festival. But Olney, Illinois may be the most intense about its high population of albino squirrels. There is a $750 fine for killing the all-white animals, and they have the legal right-of-way on roads. There's an official city count of the squirrels each year, and in 1997, realizing that local cats posed a threat to the beloved rodent residents, the city council banned residents from letting their cats run loose outdoors. In 2002, the city held a 100-Year White Squirrel Celebration, erecting a monument and holding a "squirrel blessing" by a priest. Police officers wore special squirrel-themed patches for the event.

7. THEY CAN AID STROKE RESEARCH.

Ground squirrels hibernate in the winter, and the way their brains function while they do may help scientists develop a new drug that can limit the brain damage caused by strokes. When ground squirrels hibernate, their core body temperature drops dramatically—in the case of the arctic ground squirrel, to as low as 26.7°F, possibly the lowest body temperature of any mammal on Earth. During this extra-cold hibernation, a squirrel's brain undergoes cellular changes that help its brain deal with reduced blood flow. Researchers are currently trying to develop a drug that could mimic that process in the human brain, preventing brain cells from dying when blood flow to the brain is cut off during a stroke.

8. THEIR FUR MAY HAVE SPREAD LEPROSY IN THE MIDDLE AGES.

If you always warn your friends not to pet or feed squirrels because they can spread disease, put this story in your back pocket for later: They may have helped leprosy spread from Scandinavia to the UK in the 9th century. Research published in 2017 found a strain of leprosy similar to a modern variant found in squirrels in southern England in the skull of a woman who lived in England sometime between 885 and 1015 CE. The scientists suggest that the leprosy may have arrived along with Viking squirrel pelts. "It is possible that this strain of leprosy was proliferated in the South East of England by contact with highly prized squirrel pelt and meat, which was traded by the Vikings at the time this woman was alive," one of the authors told The Guardian. That may not be the most uplifting reason to appreciate squirrels, but it's hard not to admire their influence!

9. THEY'RE MORE POWERFUL THAN HACKERS.

While energy companies may worry about hackers disrupting the power grid, squirrels are actually far more powerful than cyber-whizzes when it comes to sabotaging our electricity supply. A website called Cyber Squirrel 1 documents every public record of squirrels and other animals disrupting power services dating back to 1987. It has counted more than 1100 squirrel-related outages across the world for that time period, which is no doubt a vast underestimate. In a 2016 survey of public power utilities, wildlife was the most common cause of power outages, and for most power companies, that tends to mean squirrels.

10. THEY CAN HEAT UP THEIR TAILS TO WARD OFF PREDATORS.

California ground squirrels have an interesting way of scaring off rattlesnakes. Like cats, their tails puff up when they go on the defense. A squirrel will wave its tail at a rattlesnake to convince the snake that it's a formidable opponent. Surprisingly, they whip their tails at their foes whether it's light or dark outside. Squirrels can control the blood flow to their tails to cool down or keep warm, and they use this to their advantage in a fight, pumping blood into their tails. Even if the rattlesnakes can't see the bushy tails, researchers found in 2007, they can sense the heat coming off them.

11. THEY HELP SCIENTISTS KNOW WHETHER A FOREST IS HEALTHY.

Researchers look at tree squirrel populations to measure just how well a forest ecosystem is faring. Because they depend on their forest habitats for seeds, nesting sites, and food storage, the presence and demographics of tree squirrels in an area is a good bellwether for the health of a mature forest. Studying changes in squirrel populations can help experts determine the environmental impact of logging, fires, and other events that alter forest habitats [PDF].

12. THEY CAN LIE.

Gray squirrels know how to deceive. They can engage in what's called "tactical deception," a behavior previously only seen in primates, as a study in 2008 found. When they think they're being watched by someone looking to pilfer their cache of food, the researchers discovered, they will pretend to dig a hole as if burying their acorn or nut, but tuck their snack into their mouth and go bury it elsewhere.

13. THEY WERE ONCE AMERICA'S MOST POPULAR PET.

Though some states currently ban (or require permits for) keeping squirrels as pets, it was once commonplace. Warren G. Harding kept a squirrel named Pete who would sometimes show up to White House meetings and briefings, where members of Harding's cabinet would bring him nuts. But keeping a squirrel around wasn't just for world leaders—the rodent was the most popular pet in the country, according to Atlas Obscura. From the 1700s onwards, squirrels were a major fixture in the American pet landscape and were sold in pet shops. Despite Harding's love of Pete, by the time he lived in the White House in the 1920s, squirrel ownership was already on the wane, in part due to the rise of exotic animal laws.

14. THE MERE SIGHT OF JUST ONE COULD ONCE ATTRACT A CROWD.

The American cities of the 1800s weren't great places to catch a glimpse of wildlife, squirrels included. In fact, the animals were so rare that in the summer of 1856, when a gray squirrel escaped from its cage inside a downtown New York apartment building (where it was surely living as someone's pet), it merited a write-up in The New York Times. According to the paper, several hundred people gathered to gawk at the tree where the squirrel took refuge and try to coax the rodent down. In the end, a police officer had to force the crowd to disperse. The paper did not document what happened to the poor squirrel.

15. IN THE 19TH CENTURY, THEY WERE TASKED WITH TEACHING COMPASSION.

In the mid-1800s, seeking to return a little bit of nature to concrete jungles, cities began re-introducing squirrels to their urban parks. Squirrels provided a rare opportunity for city slickers to see wildlife, but they were also seen as a sort of moral compass for young boys. Observing and feeding urban squirrels was seen as a way to steer boys away from their "tendency toward cruelty," according to University of Pennsylvania historian Etienne Benson [PDF]. Boy Scouts founder Ernest Thompson Seton argued in a 1914 article that cities should introduce "missionary squirrels" to cities so that boys could befriend them. He and other advocates of urban squirrels "saw [them] as opportunities for boys to establish trusting, sympathetic, and paternalistic relationships with animal others," Benson writes.

But young boys weren't the only ones that were thought to benefit from a little squirrel-feeding time. When the animals were first reintroduced to parks in the 19th century, feeding squirrels was considered an act of charity—one accessible even to those people who didn't have the means of showing charity in other realms. "Because of the presence of urban squirrels, even the least powerful members of human society could demonstrate the virtue of charity and display their own moral worth," Benson writes. "Gray squirrels helped reshape the American urban park into a site for the performance of charity and compassion for the weak." Even if you were too poor to provide any sort of charity for someone else, you could at least give back to the squirrels.

BONUS: THEY USED TO HATE TAX SEASON TOO.

Though notably absent from big cities, much of the U.S. was once overrun by squirrels. The large population of gray squirrels in early Ohio caused such widespread crop destruction that people were encouraged—nay, required—to hunt them. In 1807, the Ohio General Assembly demanded that citizens not just pay their regular taxes, but add a few squirrel carcasses on top. According to the Ohio History Connection, taxpayers had to submit a minimum of 10 squirrel scalps to the town clerk each year. Tennessee had similar laws, though that state would let people pay in dead crows if they couldn't rustle up enough squirrels.
