Can Coffee Really Stunt Your Growth?

According to conventional wisdom, coffee is solely a drink for adults.
Kids rarely complain—after all, it’s an acquired taste, and a bitter cup of java isn’t exactly irresistible to a young child’s palate.
HealthyWay
But the idea that kids can’t have coffee has nothing to do with taste; it’s based on the well-known assertion that coffee stunts growth. It sounds plausible, for some reason, but is it really based in science?
Possibly, but the effect is likely overstated. At one point, scientists believed that caffeine affects calcium absorption, preventing the body from using the mineral effectively. Heavy caffeine consumption was even thought to be a risk factor for osteoporosis. More recent studies have prompted a reversal on this position, however.
HealthyWay
Caffeine doesn’t seem to meaningfully affect calcium absorption, according to a 1992 study published in the Journal of Bone and Mineral Research.
“High caffeine consumption has been proposed as a risk factor for osteoporotic fracture, but the evidence associating high caffeine intake with low bone density is inconsistent,” wrote the study’s authors, noting that caffeine intake doesn’t seem to be an important osteoporosis risk factor.

A cup of coffee probably won’t stop a growing body from growing.

But that doesn’t make caffeine a good dietary addition for younger kids.
HealthyWay
“There are lots of things we can’t do because we’re not old enough or mature enough,” said Kevin Shannon, MD, a professor of pediatric cardiology and director of pediatric arrhythmia at the Mattel Children’s Hospital of the University of California, Los Angeles, in an interview with TODAY. “Caffeine should probably be added to that list.”
That’s not because of the stimulant’s purported growth-stunting capabilities but its effect on the cardiovascular system. A 2014 study from the University of Buffalo’s School of Public Health and Health Professions showed that a moderate amount of caffeine can increase blood pressure and slow heart rates in young children.
HealthyWay
The slow heart rates occur because the heart is forced to compensate for rising blood pressure. The effect is reversed at high caffeine dosages.
Caffeine can also contribute to insomnia and other sleep disorders, which may actually have an effect on growth. It’s a diuretic, so it can cause dehydration in large amounts, and it can cause jitters, headaches, gastrointestinal distress, and withdrawal symptoms.
These symptoms are often more pronounced in kids, since a relatively small amount of caffeine has a greater effect on a smaller body.
HealthyWay
“Caffeine is absorbed in every body tissue,” wrote Marcie Schneider, MD, adolescent medicine physician and a former member of the American Academy of Pediatrics Committee on Nutrition, for Live Science. “It increases your heart rate and it increases your blood pressure. Caffeine changes your body temperature and your gastric juices. It changes how attentive you are, and can really cause trouble in terms of sleep.”

Schneider also provided an alternate hypothesis for the “coffee stunts your growth” belief.

“Caffeine is a stimulant, and therefore it may change their appetite,” she wrote. “Adolescents gain half of their adult weight in their teenage years. If caffeine curbs their appetite in some way it could affect their growth.”
While that sounds completely plausible, we should note that we couldn’t find direct evidence to back up that assertion.
HealthyWay
Unfortunately, kids are drinking quite a bit of caffeine, although they rarely get their fix from coffee. A 2010 study published in the journal Pediatrics found that 75 percent of children consume caffeine on a daily basis. Most of that comes from sodas, chocolate, and energy drinks.
Parents also frequently mistake energy drinks for sports drinks, which is problematic; many energy drinks have much more caffeine per serving than coffee or soda. Some also contain taurine, which neutralizes some of the negative effects of caffeine, potentially allowing children to consume even more of the drinks.
HealthyWay
Sodas, energy drinks, and blended coffee drinks also have high amounts of sugar. High-sugar diets are linked to obesity and malnutrition in kids, so parents should certainly try to cut out unnecessary sugars wherever possible.

Some doctors say that ideally, children shouldn’t consume any caffeine.

“I think there is no place for caffeine in a child’s diet until they become young adults, at age 18,” said Jessica Lieb, registered dietitian at the Children’s Hospital of Pittsburgh of the University of Pittsburgh Medical Center. “And even in adults, it’s important to be really careful. As in all things, caffeine should be consumed in moderation.”
For some families, a “no caffeine” rule is impractical, but most experts say that parents should establish some limits.
The Canadian government suggests a maximum recommended intake of 45 milligrams per day for children aged 4 to 6. For reference, a 12-ounce diet cola contains roughly 45 milligrams, and a typical cup of coffee contains about 95 milligrams.
HealthyWay
The bottom line: Young kids shouldn’t have coffee. Older teenagers can probably gradually add caffeine to their diets with few ill effects. Provided that they couple their coffee with a balanced breakfast after a good night’s sleep, their bodies should grow just fine.

6 Secrets Nurses Wish They Could Tell You

My brother once spent a month in the intensive care unit (ICU) after a car accident. During that time, his doctors would breeze in the room, look at his chart, and spend a few moments discussing his care before popping back out.

HealthyWay

His nurses, however, were there 24 hours a day. They changed his bandages, washed his hair when he started to smell, and didn’t flinch when he made some very inappropriate comments after a bad interaction with some of his medication.

The women and men who care for others as nurses are professionals. Never “just a nurse.” Nurses are equal parts healthcare providers, patient advocates, therapists, and superheroes. Most of us though, don’t realize just how vital nurses are in day-to-day hospital operations.

HealthyWay

We asked nurses to weigh in on what they wish patients knew about their job. What they shared with us just might surprise you.

1. “One of the things that annoy nurses the most is when people say, ‘I think I have this diagnosis because I looked it up on Google.'”

Thanks to Dr. Google, people can look up aches and pains online. In moderation, googling symptoms isn’t so bad, but it’s easy to fall down the rabbit hole of cyberchondria. It starts by looking up that niggling pain in your stomach.

HealthyWay

Before you know it, you’ve diagnosed yourself with one of the rarest incurable diseases in the world.

Among people who used online symptom checkers, 67 percent later sought unnecessary medical treatment. Excessive visits to the emergency room or doctor’s office place a greater strain on nurses who already have a full patient load.

HealthyWay

Because people seek unnecessary treatment as a result of online research, nurses have less time to spend caring for patients who are in need of medical treatment.

What’s more, nurses and doctors say, is that cyberchondria often leads patients to try to treat their symptoms on their own, which can land you in the emergency room even if you were perfectly fine before.

HealthyWay

Instead, nurses and doctors recommend that if you feel sick or are in pain, it’s always best to simply call your healthcare provider to see if you need to come in to be seen.

2. “In the ICU, it’s frustrating when patients say we’re neglecting or ignoring them…when in reality if I’m not sitting outside my patient’s room then I’m in another room helping with a patient who is crashing or coding.”

In critical care units, nurses are trained to deal with life-threatening medical conditions.

Although ICU nurses often have a much smaller patient load—typically one to two patients at a time, emergency patient situations often arise that demand a nurse’s full attention until a patient is stabilized.

HealthyWay

According to one ICU nurse, “It took me a few years to not hate my job, and that was when I realized you’re not going to have a quick fix with all of your patients.”

3. “We need lunch breaks and bathroom breaks too!”

Although restroom and lunch breaks are figured into the salaries of many nursing professionals, most rarely get to take a break during shifts that can be as long as 12 to 24 hours.

That’s because most nurses are supposed to take breaks using a buddy system, in which a nurse covers the patients of a nurse who’s on break.

HealthyWay

However, according to research done by NPR, one “nurse says she rarely stops. Not for 12 hours. She’s an emergency room nurse in a busy urban hospital. The ideal, she says, would be one nurse for every three patients in her ER. But she typically cares for five patients or more—often eight, if she’s covering for a colleague taking a lunch break. She says there are times when she can’t leave patients’ bedsides.”

The inability to take a break is one of the biggest reasons for nurse burnout on the job. In fact, the majority of nurses feel “stressed, overworked, underappreciated, and underutilized.”

HealthyWay

Ultimately, this affects a nurse’s ability to provide the best patient care. In some states, nurses have taken action, winning legal battles to take appropriate breaks. When they get those breaks, nurses are happier, and patients receive better care.

4. “Could you please stop talking while I am trying to listen to your heart/lungs?”

While you’re busy explaining your symptoms in great detail, your nurse is busy trying to assess your vital signs. A patient’s blood pressure, pulse, temperature, and respiratory rate determine the next steps in their care, which is why it’s extremely important to stay silent during this examination.

HealthyWay

Vital signs ought to be the most reliable pieces of information in a patient’s file, but when a nurse is distracted at the time of examination, the results are often incorrect. This can have serious consequences for a patient’s health.

For example, a patient might receive an inaccurate diagnosis based on the vital signs that were recorded.

HealthyWay

So don’t take it personally if a nurse cuts your conversation short. Although chatting with your nurse might make you feel more at ease, your nurse is simply trying to stay focused on providing the best medical care.

5. “I understand you are sick, and I am here to care for you. But I am not your maid, and this is not a hotel, it is a hospital.”

Hospitals have started offering more amenities to patients, in part because insurance reimbursements are now directly tied to patient satisfaction. In one survey, patients were asked to rate how quickly they received help after pressing the nurse call button without indicating if the help requested was medical in nature.

HealthyWay

“Patients have complained on the survey…about everything from ‘My roommate was dying all night and his breathing was very noisy’ to ‘The hospital doesn’t have Splenda.’ A nurse at the New Jersey hospital lacking Splenda said, ‘This somehow became the fault of the nurse and ended up being placed in her personnel file. …Many patients have unrealistic expectations for their care and their outcomes,’ the nurse said.”

Both hospitals and hotels often have cable television, but that’s really where the similarities end.

HealthyWay

A nurse’s main focus is on overall patient care. If an immobile patient asks for more water, a nurse is more than happy to accommodate that request. However, if you’re perfectly capable of fluffing your own pillow or changing your television station, think twice before pressing the call button.

6. “You know that you are having surgery, that we are operating on you, and that you are going to be naked on an operating table. Please, for the love of all things, wash yourself and clean your belly button!”

Nurses, like most people, appreciate general good hygiene in others.

HealthyWay

Bathing immobile patients is part of the job, but most nurses draw the line at patients who show up for scheduled surgery smelling less than fresh.

It’s not just because nurses have delicate noses. Bathing before scheduled surgery is recommended in most medical offices to help prevent post-op infections.

HealthyWay

Please note that although nurses want you to be clean for surgery, they do advise skipping perfumes, deodorants, and lotions that could contaminate the surgical site.

Nurses have touched millions of lives and looked after countless numbers of people in need. Let’s do our best to show them the same care they’ve shown all of us.

How To Use Your Baby's Hunger Cues To Practice On-Demand Feeding

As a brand-new mom, my first night at home was nothing short of a nightmare. I left the hospital with a sleepy babe who was barely interested in nursing and found myself staring at a wide-awake and furiously ravenous newborn at 2 in the morning on her fourth day of life.
HealthyWay
I knew she was hungry, but I couldn’t get her to latch on to my breast. We went round and round, me offering her the breast, her screaming, and me crying because I felt like I was doing something wrong. It took hours to get her to eat a full meal, and it felt like as soon as we were finished, it was time to start the whole process over again.
The next morning, I found myself making a desperate call to my lactation consultant. A few hours later we were in her office, troubleshooting our breastfeeding woes.
HealthyWay
For my baby and me, there was more than one problem to address. Her latch needed to be corrected, and I needed to pump some to encourage more milk production. But one of the biggest reasons she was so pissed was because I had been missing her hunger cues.
It wasn’t enough to follow a schedule—to feed her every few hours or to wait for her to cry. I needed to follow her lead, but I didn’t know what I was looking for.
HealthyWay
Every baby is different, but there are some general rules you can follow to make sure you are feeding them before they are so hungry that they’re angry. Follow these hunger cues outlined by lactation consultants and infant nutrition experts to determine if your infant is hungry or full.

Your Baby’s Very First Signs of Hunger

If your baby is crying, they’re actually in the late stages of feeling hungry and you’ve missed some more subtle clues that they were ready for their next meal. Babies can’t talk, but they definitely know how to communicate their needs. Hunger cues begin with some less noticeable behaviors and gradually become more obvious over time.
HealthyWay
Restlessness is one of the earliest signs an infant wants to eat, according to breastfeeding advocacy organization La Leche League. Each baby may display restlessness differently from others, but some of the most common behaviors include rapid eye movements, wriggling around, or disruptions to their sleep.
Some babies may also exhibit tension, according to La Leche League, which can look like clenched fists or rigidity of their arms.
HealthyWay
Most little ones will also smack their lips, suck on their fists, or open and close their mouths to let you know they want to eat. If you notice any of these cues, go ahead and settle into a comfy chair and give your baby a chance to satisfy their hunger.

Your Baby’s Secondary Signs of Hunger

If you missed your baby’s first signs of hunger, don’t worry, they won’t give up easily. If a newborn baby isn’t fed quickly after they first begin to experience hunger, their behavior will escalate, and their hunger cues will become more apparent.
HealthyWay
Babies are born with an amazing reflex called rooting. From their first hour of life, a typically developing baby will turn their head toward their mother’s breast or a bottle if they feel a touch to their cheek.
Their mouth will also make a sucking motion. If your baby is rooting around, this is a pretty clear indication that they are ready to eat. If they are older than 4 months—when rooting stops being reflexive and becomes an intentional action—you can be certain that rooting means your child wants to eat.
In addition to rooting, a baby who is growing hungrier may try to get in a position to nurse, according to breastfeeding resource Kelly Mom. Older babies may also start to pull on your clothes or even swat at your chest.
HealthyWay
No matter the age of your baby, fussiness can be a sign of hunger. Of course, fussiness isn’t always an indication that your baby needs to eat, but if isn’t time for sleep and a diaper change isn’t the answer, it is probably wise to give nursing a try.

Crying: Your Baby’s Last-Ditch Effort to Communicate Hunger

Many parents believe that crying is their baby’s way of communicating that they’re ready to eat, but that actually isn’t true. A baby who is crying to signal hunger is usually only doing so because their other cues have failed.
HealthyWay
Waiting until a baby is upset to initiate nursing or offer a bottle can be problematic, and some mothers may have trouble getting their baby to settle down enough to eat.
Additionally, mothers who are responsive to their infant’s hunger and satiety cues are decreasing both Mom’s and Baby’s risk for obesity, according to the journal Appetite.
HealthyWay
If you’ve missed your baby’s early hunger cues, don’t fret. Calm your baby before offering the breast or a bottle, and make a note to pay more careful attention in the future.

How do I know if my baby is full?

Whether you are breastfeeding or bottle feeding, being in tune to your baby’s satiety is just as important to their health as being aware of hunger signs.
HealthyWay
In fact, practicing responsiveness to cues babies offer that they’re ready to wrap up their meal can help decrease their chance of obesity later in life by encouraging self-regulation of hunger, according to the journal Physiology & Behavior.
The good news is that babies are pretty great at letting their mother know they’re no longer hungry. Some babies will turn their head away from the breast, clamp their mouth shut, or simply fall asleep, according to Enfamil.
HealthyWay
In some cases, babies may not break their latch but their sucking will slow or stop, which is a good indication you can break the latch to end the feeding. Older babies who aren’t hungry could become distracted by what is going on around them, becoming more interested in playing than eating.
If your baby uses a bottle, you may have to watch more closely for feeding cues. It is easier to overfeed a formula-fed baby, according to research by the University of Akron.
HealthyWay
Many parents may assume they should encourage their infant to finish their bottle, but it is actually more important to watch for your baby to signal they are through, even if that means wasting some formula.

Should I feed on demand or encourage a schedule?

Perhaps one of the most hotly debated topics among breastfeeding mothers is whether they should put their baby on a schedule or not. There are some proponents of scheduled feeding, such as Gary Ezzo, author of On Becoming Babywise. But most lactation experts advise against scheduled feedings, especially for young babies.
HealthyWay
Young babies have small stomachs, and breast milk digests more quickly than formula. Additionally, the amount of milk a mother makes will adjust based on demand, so a mother who withholds feeding her baby in an attempt to get on a schedule may see a decrease in her milk supply.
Because of this, it is recommended that mothers not space feedings out by any more than three hours and that mothers respond to their babies cues and feed on demand as much as they are able.
HealthyWay
If putting your baby on a schedule is important to you, lactation consultant Jessica Barton offers a few suggestions on her blog. First, she says it is helpful for parents to spend a couple of days paying attention the natural rhythm of their child.
Keep track of when your baby is eating and sleeping and then begin to build a schedule from there. Additionally, parents should be realistic about the length of time between feedings, since babies under the age of 6 months should nurse 10 to 12 times in a period of 24 hours.
HealthyWay
Of course, like many parenting practices, on-demand feeding isn’t an exact science. Knowing yourself and understanding your baby’s unique needs—combined with advice from your own lactation consultant—is the best approach for developing a feeding routine that works for your family.

Want To Raise Happier Kids? Parent Like The Danish

Babies cry. Tears are an infant’s way of letting their parent know they’re hungry, tired, or they need to be near their mom, and a baby’s ability to communicate those needs is important to their survival.
HealthyWay
Fussy nights and tear-filled afternoons are a reality of motherhood that most have come to accept, but that doesn’t necessarily mean most moms wouldn’t jump at the chance to cut back on tears if they knew how it’s done.
Of course, all parents like the idea of happier babies, but that is much easier said than done. When my baby fusses, I find myself working through a list of possible reasons. Does he need to eat? Is he tired or uncomfortable? Does he need a diaper change? Is he bored?
HealthyWay
Sometimes, even after I have worked my way through this mental checklist, he continues to fuss and I’m left clueless about how to soothe his frustrations.
There is one population who appears to have figured out the key to keeping their babies calm, according to a study published in The Journal of Pediatrics. Danish parents seem to have nailed down the trick to raising babies who cry less and grow into happier kids.
HealthyWay
The study took a close look at parental reports of fussing or crying in newborns as observed in 28 different studies. Researchers compiled the data on 8,690 infants, specifically examining the mean fussiness in newborn babies based on their age.
The data found by researchers shone a light on Denmark, where children cry significantly less than children in the other countries included in the study.
HealthyWay
Although it is difficult to pinpoint one specific reason that Danish parents have an advantage over new parents in the rest of the world, according to the study’s authors, they did raise a few possible areas that warrant closer examination.
For instance, there is a chance that there are economic factors that influence parents in Denmark, and parents are more responsive to their newborns’ needs. The researchers also speculated that genetics could play a part, with babies inheriting their parents’ genes that influence their temperament.
HealthyWay
Others have chimed in with theories on what influences how little Danish babies cry. Jessica Joelle Alexander, author of The Danish Way of Parenting, told The Guardian that she believes paid maternity leave could be directly tied to this phenomenon.
Denmark has one of the best maternity leaves out there, giving mothers a month off before their baby is born and then an entire year at home with their child after their birth.
HealthyWay
It makes sense that Danish babies are happier, because their parents are less stressed and more capable of responding to their needs during that first year.

Danish babies grow into happier kids.

Fewer tears aren’t the only bragging rights Danish babies have over their fellow children around the globe. Older kids in Denmark are also all around happier than children in the rest of the world. Each year countries around the world are carefully surveyed for a World Happiness Report. In this report, the Danish are consistently found to be the happiest people in the world.
HealthyWay
Of course, there isn’t one single factor that gives Denmark the corner on happiness, but there are definitely people making some convincing arguments. For instance, inequality of overall well-being is higher in countries that report low happiness scores.
One of the most popular theories, perhaps, is that happiness is directly linked to the way the Danish parent. In fact, there is an entire book on the topic, comparing parenting methods in America with those used in Denmark.
HealthyWay
From the way we discipline to the time our children spend outdoors, The Danish Way of Parenting makes a pretty convincing case that American parents could raise happier children if they were simply willing to take a closer look at what parents are doing in Denmark. In fact, there is even a Ted talk discussing this approach.

What American Parents Can Learn From Denmark

So what’s the secret to raising happier kids? According to the authors of The Danish Way of Parenting, there isn’t a simple answer. In one article for Brit + Co, the writers outline seven keys to parenting the Danish way. It’s evident that implementing these practices would require a complete reworking of the typical American parenting model.
HealthyWay
American parents, for instance, tend to rely on harsher parenting practices, according to The Guardian. The majority of parents in the States are still using spanking in their discipline toolbox, despite research that indicates the ineffectiveness and harmfulness of this practice.
In contrast, Danish parents rely heavily on using empathy to connect with their children, providing clear boundaries but avoiding ultimatums or demanding obedience. Instead, parents in Denmark work to develop a mutual respect with their children, explaining the reasoning behind rules and calmly responding to challenging behaviors.
HealthyWay
Parenting happy children extends beyond what we do when our kids are upset or challenging our patience. How we approach their downtime directly plays into the state of their well-being, according to the authors of The Danish Way of Parenting.
Danish parents place a high priority on being together—so much so that their word for togetherness, hygge, has become a trend all over the Western world. For the Danes, family time isn’t a trend, however, it is a daily way of life. Whether it’s family meals, a hike, or a project, kids who spend regular time with their parents are more secure and all around happier.
HealthyWay
Statistics regarding the state of the family dinner in America indicate that 25 percent of families eat together fewer than three nights a week. If this is any indication of how the rest of the day is spent—and we’re pretty sure it is, we can say with confidence that American families are not spending enough time together.
The flipside of the practice of togetherness in Danish families is that children are also given an incredible amount of independence. Whereas American parents may feel pressure to keep their kids scheduled or offer entertainment, Danish families think free play is the key to a happy childhood.
HealthyWay
When it comes to the logistics of American parenting, there is a marked difference. For instance, children in America have quite busy schedules, and 1 and 5 parents with an average income of $75,000 says their kids’ lives are hectic.
After-school activities dominate the schedules of American children, according to the Pew Research Center, with 73 percent of parents reporting their child is in sports and 54 percent in the arts after school or on weekends.
HealthyWay
Even children with free time may not be given a lot of opportunities for unsupervised play, since most American parents believe kids should be at least 10 years old before they can play outside without a parent present.
It is easy to be overwhelmed by the huge difference between Danish and American parenting, especially when we have so little control over factors like paid maternity leave.
HealthyWay
Don’t let that discourage you if you would like to make same changes. Start small, by setting goals for cutting back on screen time and getting your kids outside more often, sitting down for a family meal three or more times a week, or reading up on responding to tantrums with empathy instead of anger.
Even a small change toward more positive parenting can make a big difference in the well-being of your child.

Turns Out Your Stomach Bug Isn't Always Caused By The Last Thing You Ate

At first, you think hopefully that the rumbling in your belly is just due to mild indigestion or gas. But then you break out in a cold sweat, the noises in your stomach get louder, and you’re in a race to get to the bathroom.
HealthyWay
Acute gastrointestinal events like this happen to the average person about once a year, according to the Centers for Disease Control and Prevention. During these events, most people tend to blame the last thing they ate, but that’s actually rarely the culprit.
So what does have us scrambling for the Pepto Bismol? Turns out there are several ways you can get a stomach bug.

Viral and Bacterial Infections

Stomach Flu
Gastroenteritis, commonly referred to as stomach flu, is usually caused by a viral infection. Symptoms can include severe nausea, cramping, diarrhea, and dehydration.
HealthyWay
Children are most susceptible to strains of stomach flu like norovirus and rotavirus, because these types of gastroenteritis are extremely contagiousViral stomach flu spreads through close contact with other infected individuals (who can remain contagious for up to three weeks after recovery).
Food Poisoning
Food poisoning, or bacterial gastroenteritis, occurs when bacteria and parasites come in contact with food items. The most common causes of food poisoning are E. coli, Salmonella, and Staphylococcus.
HealthyWay
Food poisoning generally isn’t contagious from person to person, but anyone who ate the food in question is at risk for developing symptoms such as acute abdominal cramps, vomiting, and diarrhea.
The last food you ate is not likely to have caused your food poisoning. It usually takes between 10 and 14 hours to fully digest a meal, so the most likely offender is actually the food you ate one to two days prior to feeling ill.

Natural Stomach Bug Remedies

If you suspect you have a stomach bug due to viral or bacterial infection, there are some natural remedies you can try to ease symptoms.
Alternate hot and cold.
If you’re suffering from abdominal cramping, try a heating pad or even a warm homemade rice bag to alleviate pain and allow muscles to relax.
HealthyWay
When you break out in a cold, clammy sweat, place a cool, wet cloth on your forehead. The science behind this is a bit complicated, but essentially, as the water evaporates, it creates a cooling effect against your skin, which results in comfort for you.
Be a BRAT.
Ok, don’t really be a brat. But you may want to try the BRAT diet if you have a stomach bug.
HealthyWay
Bananas, rice, applesauce, and toast are all great foods to try when you’re suffering from gastrointestinal distress. These foods are bland, high in potassium, and aid in digestive recovery.
Skip cold drinks.
A frosty beverage sounds refreshing when you’re suffering from a stomach bug, but it’s actually better to drink room-temperature drinks that are high in electrolytes to replenish nutrients that have been lost through nausea and diarrhea.
Ginger
There’s a reason people head straight for the ginger ale at the first sign of a stomach bug. Ginger is a superfood that contains antioxidants and has anti-inflammatory properties that can soothe an inflamed gut.
HealthyWay
Flat ginger ale can help alleviate tummy trouble, but ginger tea and crystallized ginger root are also excellent remedies.
Avoid certain irritants.
A hot cup of coffee might be the furthest thing from your mind when you’re suffering from a stomach bug. But if you’re feeling better, you might be tempted to reach for the caffeine.
HealthyWay
It’s best to hold off on digestive stimulants such as coffee, chocolate, and fatty, greasy foods for a few days until your symptoms completely resolve. Otherwise you might find yourself facing a second round of gastrointestinal distress.

Non-Contagious Causes of Stomach Upset

Not all stomach bugs are caused by an infection.
HealthyWay
Have you unfairly blamed yesterday’s Chinese takeout for your stomachache? A food allergy or reaction to medication may be the cause instead.
Food Allergies
Allergies tend to cause itchy eyes, a sore throat, and a runny nose. If you’re allergic to certain foods, however, your allergy symptoms might appear similar to a stomach bug.
Almost any food is capable of causing an allergic reaction, but the most common offenders are peanuts, shellfish, milk, soy, and wheat.
HealthyWay
If you think your stomach bug is caused by food allergies, try eliminating that particular food from your diet for a few days. If you notice your symptoms clearing up, then you may be allergic to that particular food.
Fortunately, food allergies aren’t contagious. Your doctor may recommend allergy testing to determine exactly which foods trigger symptoms. Treatment can include eliminating certain foods, prescription antihistamines, or immunotherapy for severe food allergies.
Medication-Induced Reaction
Medicine is supposed to make you feel better, right?
In some cases, prescribed medicines—especially antibiotics, anti-inflammatory drugs, and angiotensin converting enzyme (ACE) inhibitors—can cause gastrointestinal distress that may make you think you’ve got a stomach bug.
HealthyWay
Antibiotics in particular can cause severe upset stomach and diarrhea because they wreak havoc on bacteria in the large intestine.
It’s important to continue taking antibiotics and other prescribed medications per your doctor’s instructions. If you’re suffering from a medication-induced stomach bug, make like Jamie Lee Curtis and try a probiotic. Probiotics contain good bacteria that aid digestion and can help restore the natural bacteria balance to your gut.

When to Call the Doctor

A stomach bug should begin to resolve on its own within two to five days. If you do not start to feel better or if your symptoms get worse, you should call your doctor.
HealthyWay
Other signs you should call your doctor include:
–Weakness, dizziness, or trouble urinating (which can be signs of dehydration)
–A persistent high fever lasting more than two days in children and more than five days in adults
–Blood in stool
–Vomiting that lasts more than two days

Stomach Bug Prevention

Unfortunately, the flu shot will not protect against viral and bacterial gastroenteritis. Although these ailments are commonly called the stomach flu, they’re totally unrelated to influenza, which is a respiratory virus.
HealthyWay
The best way to steer clear of tummy trouble is to always wash your hands or use hand sanitizer before preparing or eating a meal.
Think about all the things you touched during the day and how many people were there before you. That’s a lot of germs. Washing your hands is the best way to prevent viral and bacterial infections from spreading.
HealthyWay
If anyone in your family has already contracted a stomach bug, it’s not too late to stop the virus from spreading. Disinfect your home from top to bottom. This includes doorknobs, kitchen counters, bathrooms, and linens that the sick person in question has used.
It might sound harsh, but if you can quarantine the infected person temporarily as you disinfect, you just might avoid contracting the stomach bug yourself.
HealthyWay
If you’ve already contracted the stomach bug, you can help spare others by staying home as long as possible. Even though you might start to feel better within two to three days, you’re actually contagious for up to three weeks.
You may not be able to avoid going back to work for three weeks, but you can disinfect your work space, wash your hands often, and avoid physical contact with coworkers and friends until you’re no longer contagious.
HealthyWay
Twenty million people will get the stomach bug this year. Now that you’ve got all the facts, fingers crossed that you won’t be one of them!

What Your Baby Starts Learning In The Womb

During my first pregnancy, I was surprised to find I felt a strong pull to talk with my baby. Every day was a new experience for me, and so many parts of my pregnancy felt unreal.
HealthyWay
When I would lie in bed at night chatting about the day or simply saying, “Hello in there,” I found I felt more connected to my child. It was hard to imagine that inside my growing belly a human being already existed, but the more I talked to the baby in my womb the more comfortable I felt with the idea of becoming a mother.
As it turns out, having a chat with her unborn child doesn’t just make the mother feel connected, it actually has an impact on her developing baby.
HealthyWay
Science has found that babies begin learning in the womb and that they are forming memories about the things they are exposed to the most before they are born.

The Science of Prenatal Memories

Since scientists can’t ask babies what they remember from their time spent in their mothers’ wombs, they have had to get creative when it comes to figuring out what newborns remember.
HealthyWay
Researchers have relied heavily on studying animals to indicate how early memories are formed, why they are forgotten, and what kind of implications these memories have for a child.
What most moms know simply from observation is that most children and adults can’t report detailed memories from before their birth. Many have hypothesized on why this is the case (such as Freud’s theory of repression), but it wasn’t until recently that we better understood the facts.
Observing the brains of infant rats clued researchers in to what happens to early memories, and they published their findings in the journal Science. The truth is, the infant brain is developing at a rapid pace.
HealthyWay
This growth requires the formation of new brain cells, and these new brain cells actually crowd out the connections made by early memories. When researchers slowed down the brain development of infant mice, they actually found that early memories were more cemented in their brain.
The application of this finding to human beings is that the developing brain is making memories in the womb, but as your child grows older their amazing neurological development is erasing those memories.
HealthyWay
It’s fascinating knowing that babies start learning in the womb and can still remember many of the things they learn after birth.
Want to know more? Here are the facts on what your baby remembers from the womb.

Your baby remembers the words you say.

It turns out that talking to my baby while she was growing inside of me wasn’t as silly as it sometimes felt. The truth is, she was forming memories of the words I said repeatedly—and your baby is too.
HealthyWay
A team of scientists at the University of Helsinki discovered the extent of a newborn’s language memory by giving mothers a recording of a completely made-up word. These mothers were asked to play this recording repeatedly over their last months of pregnancy. By the time the babies were born, they had heard the sound more than 25,000 times.
After the babies were born, the researchers used EEG technology to test for recognition of the word. What they found was that when compared with babies who hadn’t heard the word during pregnancy, the brains of babies who had been exposed to the word in the womb remembered it after birth.
HealthyWay
The practical implications of this information aren’t clear. Typically mothers are discouraged from playing loud recordings near their womb because they may cause overstimulation. Researchers hope further studies can reveal the potential uses for the discovery of language learning in utero.

Your baby remembers your voice.

It isn’t just the words your babies hear that matter, the people they hear most frequently have an impact their prenatal memories, too.
HealthyWay
Research has compared how infants respond to the voices of strangers to those they hear most often during the third trimester, and it was undeniable that they prefer familiar voices. It shouldn’t be surprising that among all of the familiar voices they heard after birth, babies showed preference for the voice of their mothers.

Babies remember their birth mother’s native language.

Amazingly, babies are forming memories of their mother’s native language long before they start talking. One study took a close look at the language memory of internationally adopted children, specifically those adopted immediately following birth.
HealthyWay
What they found was that although these babies hadn’t been exposed to their mother’s native tongue since their birth, they recognized it and showed preference for it. These findings indicate that babies begin to learn their native language in the womb, according to The New York Times.

Your baby remembers the music you play.

We’ve all seen those prenatal speakers—the ones that can be attached to a mother’s growing bump, but is there any merit to this gadget? Or are manufacturers simply looking to make a buck off of expectant parents?
HealthyWay
The answer is yes and no. Babies do remember the music they hear in the womb, according to research by the University of Helsinki, but there isn’t any known development associated with playing it loudly near your growing belly during pregnancy.
Researchers instructed 12 expectant mothers to play “Twinkle, Twinkle Little Star” five days a week during the last several weeks of their pregnancy, and they also followed a control group of 12 mothers who did not.
HealthyWay
These babies were exposed to the song again immediately following their birth and at the age of 4 months. Researchers found that they exhibited a brain response to the song that the control group did not.

Your baby remembers the food you eat.

The old joke about eating for two may actually have some merit. If you’re hitting up your favorite taco place twice a week (thanks to those killer pregnancy cravings), your baby is getting a taste, too.
HealthyWay
There is convincing research that suggests when your baby gulps in the amniotic fluid that surrounds them in the womb, the flavor changes based on what mom has been eating lately, according to NPR. Additionally, after babies start eating solid foods, research suggests they show preference for foods they were repeatedly exposed to in the womb.

Why Prenatal Memories Matter

The science behind the formation of prenatal memories is fascinating. If babies lose track of most of their memories from their time in the womb, why does any of this matter?
HealthyWay
Researchers believe that infant memories include more than the words they hear or the music they’re exposed to and that the effects of these memories aren’t all positive.
The truth is, some researchers are certain that prenatal exposure to stressful noises may have an adverse effect on neurological development. Because of this, they believe there may be value in encouraging mothers to avoid situations that involving yelling, loud music, or obtrusive workplace noises.
HealthyWay
When it comes to the food you eat while you’re pregnant, this research matters because scientists believe that what you eat may influence your child’s own food preferences after birth.
Of course, don’t feel anxious if your pregnancy aversion kept you from eating those dark, leafy greens every day. You can always change your child’s palate by repeatedly exposing them to new flavors once they start eating solid foods.
HealthyWay
So what does this research mean for the expectant mom? It means you don’t have to change much about what you are doing already: Avoid stressful or overstimulating noises if possible and keep chatting with your unborn baby.

5 Unexpected Ways Your Body Can Totally Betray You

When I was 5 years old, I saw Santa Claus in our living room. I had crept out of my room to sneak into bed with my parents when I very clearly saw a man filling up our Christmas stockings. 

HealthyWay

Although my parents assured me the next morning that I was dreaming, I have firmly stood by my belief that I was wide awake and saw Santa Claus in our living room. Sadly (although unsurprisingly) my recollection of Santa Claus was actually a false memory.

HealthyWay

Did you remember to take out the trash? You distinctly remember doing it, yet it’s still in the bin when you arrive home. False memories can also have devastating repercussions, especially for those who develop false memory syndrome as a defense against childhood trauma.

As you may have already surmised, I actually saw my father filling our Christmas stockings. He put me back to bed with the hope I wouldn’t remember seeing him in the middle of the night.

HealthyWay

The next morning, rather than telling the truth, my parents corroborated my story. It took up a permanent place in my memory bank ever since. As an adult, I realize that Santa (probably) isn’t real. But the memory of seeing Santa is so real to me that it’s become part of my personal identity and helped shaped my worldview.

Because I believed I saw Santa when I was 5, I’ve always been open to believing in things you can’t necessarily see. If I hadn’t had this memory, I might not be so willing to believe in the unknown.

HealthyWay

Turns out that’s not the only way the body can be a total traitor. Tricking your brain into fabricating memories is just one of the unsettling ways the body can betray you.

1. It can trick you into believing you have ghost hands.

Up to 95 percent of amputees report feeling some kind of phantom limb syndrome after losing a limb. Phantom limb syndrome occurs when people feel real sensation, like an itchy palm, in the limb that has been removed.

HealthyWay

But did you know that phantom limb syndrome can occur in people who haven’t lost a limb?

Scientists call this phenomenon the rubber hand illusion. In a 1998 study, participants sat at a table with their right hand hidden from view, and a fake hand was placed on top of the table. When both the participant’s real hand and the fake hand were touched at the same time, 80 percent of the participants then believed the rubber hand was their real hand.

HealthyWay

In subsequent studies, research showed that a rubber hand wasn’t even necessary for people to feel the sensation.

Researchers removed the fake hand and simply brushed the air where the hand had been.

HealthyWay

“We discovered that most participants, within less than a minute, transfer the sensation of touch to the region of empty space where they see the paintbrush move, and experience an invisible hand in that position,” said researcher Arvid Guterstam, a neuroscientist at the Karolinska Institute in Stockholm.

2. It can cause you to see things—after you’ve lost your sight.

Similar to phantom limb syndrome, some people develop “phantom vision syndrome,” seeing vividly real colors, shapes, and objects after they’ve lost their sight. People who develop this phantom vision, also called Charles Bonnet syndrome (CBS), experience these visual hallucinations on a daily basis.

HealthyWay

Bee, a woman who developed Charles Bonnet syndrome after a glaucoma diagnosis, thought she’d had too much coffee the first time she experienced a hallucination. She’d seen a wall of mud in the grocery store that seemed so real that she felt she couldn’t put an item back on the shelf.

CBS can occur in individuals who lose some or all of their vision due to diseases such as macular degeneration, glaucoma, or diabetic neuropathy.

Because these eye conditions typically strike people who are over the age of 60, CBS is often misdiagnosed as an early stage of dementia. But people with CBS do not exhibit any symptoms of dementia other than vivid hallucinations.

HealthyWay

According to ophthalmologist Jonathan Trobe, “The brain is doing a mash-up of stored visual memories.” Rods and cones in the eyes cease to function, and the brain essentially invents images to make up for the lack of actual input. Thus the hallucinations.

3. It can take away your ability to understand language.

“Art, you know that thing on the car—the thing on the wheel?”

“What wheel? The steering wheel?”

HealthyWay

“No, the one with the tire.”

“Well, what about it?”

“Well, I noticed the middle part is gone.”

“You mean the hubcap?”

“Yes, the hubcap.”

Seven sentences to pinpoint the word “hubcap.”

Everyone has had that moment when they just can’t think of a simple word. It’s incredibly frustrating, and for Marion Rasmussen, it was everyday life, thanks to aphasia.

Aphasia is a neurological condition that can impair language comprehension as well as the ability to read and write. Aphasia is almost always the result of brain damage and can range from a mild annoyance—such as forgetting the word for “toast”—to completely robbing a person of the ability to communicate while leaving their intellect intact.

HealthyWay

There is no cure for aphasia, but treatment is aimed at improving a patient’s language and communication skills through a variety of therapies.

4. It can leave you unable to feel pain.

Ask any woman who has given birth, and she’ll probably tell you that the inability to feel pain sounds like a dream come true. For people with congenital insensitivity to pain with anhidrosis (CIPA) like Ashlyn Blocker, though, it’s more like a nightmare.

HealthyWay

Ashlyn was diagnosed with the disorder as a baby, but her first serious injury occurred when she placed her hand on a hot pressure washer and wasn’t fazed by the red blisters on her palm.

Ashlyn was just 3 years old.

CIPA is caused by mutationsAshlyn Blocker/Facebook


in a gene called PRDM12. Essentially, CIPA turns off the receptors that allow us to feel pain, cold, and heat. People with CIPA are at a greater risk for high fevers, especially in childhood. This can be fatal, because CIPA inhibits a person’s ability to sweat and help cool the body down.

HealthyWay

Currently, CIPA treatment is focused on preventing infections, fevers, and injury due to accidental self-harm.

5. Alternatively, it can also make you immune to anesthesia.

For people like Jenny Morrison, who suffers from Ehlers-Danlos syndrome, local anesthesia has no effect during medical procedures.

HealthyWay

Anesthesia “works for a few minutes and wears off very quickly,” she says. “In some people it doesn’t work at all, but for me it probably lasts about 10 minutes.”

Ehlers-Danlos syndrome (EDS) is actually a group of 13 connective tissue disorders that are typically characterized by joints that stretch more than normal, overly stretchy skin, and fragile muscle tissue.

Not all types of EDS cause immunity to anesthesia. Researchers still don’t clearly understand the link between EDS and local anesthesia, but most believe it’s related to the extreme flexibility of connective tissue. Some research shows evidence that since the connective tissue is so loose, the anesthesia quickly slips away from the site being numbed.

HealthyWay

There is no treatment for this peculiar side effect of EDS, but people with the disorder can opt for general anesthesia instead, meaning they’ll sleep through the procedure.

The Science Of Attraction: Men Are Subconsciously Looking For These 8 Things In A Woman

Your heart races. You get sweatier. You keep swallowing, and it’s hard to focus on the words you’re stringing together to form a sentence because your head is buzzing with a concoction of feel-good chemicals.
Those initial waves of attraction can knock you off your feet. More often than not, the first powerful feelings you experience for someone you’re attracted to seem inexplicable and maybe even nonsensical.
Why do we latch on to some people the way we do and not others? Is it just some ineffable, spiritual connection?
HealthyWay
The truth is, attraction isn’t random. Science can explain a lot of why we feel what we feel for a person who catches our eye.
As it turns out, even when he isn’t aware of it, a man often gets romantically involved with a woman he sees has certain qualities that are biologically coded to mean “healthy” and, by extension, “fertile.”
He may think he is simply on the hunt for his next date, but thanks to evolution, he is also subconsciously looking for a partner for his role in the survival of the human race.
HealthyWay
This innate drive to recreate can explain these eight things men are hardwired to look for in a potential lover.

1. It’s in her hips.

Biology is often to blame for why we do many of the things we do. Check out the video below to find out why most men look at body shape when searching for a significant other.

One 2017 study found a correlation between the number of children a woman had and her waist-to-hip ratio (WHR). The study looked at nearly 1,000 women from seven non-industrial societies in Sub-Saharan Africa, Western Siberia, South America, and South Asia; of this group, the women who had borne more children had higher WHRs on average.
These findings suggested that this preference for a lower WHR—the sweet spot seems to be around 0.7—may be because it is a biological indicator that a woman has not borne many (if any) children, meaning she’s got, in theory, the best of her baby-making days ahead of her.
So, contrary to the popular notion that low WHR equals high fertility, and that this quality alone is what’s prized by dudes on a subconscious level, it seems to be that low WHR indicates a limited number of previous pregnancies. The study’s authors offer a number of explanations for why this would be appealing, including that men aren’t typically thrilled about parenting another man’s kid: “from an evolutionary point of view, a male investing in another man’s children is synonymous to a man supporting his opponent’s reproductive success.”
Heartwarming, really.

2. It’s all about symmetry.

Although you probably learned all about it in art class or geometry, men’s biology seems to be fixated on symmetry. Symmetry is the idea that—when divided in half—each side of an object, person, or image mirrors the other.
HealthyWay
Of course, men aren’t simply attracted to any symmetry they see. (Unless they’re one of those 19th-century male nature writers who was aroused by plants.) We are all specifically wired to look for this characteristic in other human beings and use it as a subconscious tool for rating attractiveness, according to the journal Symmetry.
There are a few different theories about why this is the case. Some researchers think symmetry is believed to be an indication of overall health.
HealthyWay
There are others who believe that because symmetrical images are easier to process visually, our brain is wired to show preference for this characteristic.

3. Let your hair down.

If you have ever suspected that men prefer women with longer hair, you were totally onto something.
HealthyWay
The way a woman wears her hair does influence how the opposite sex sees her, according to a 2004 study in the journal Human Nature. This survey found that women with longer hair were rated by male participants as appearing healthier and more attractive.
Admittedly, hairstyle seems to have a very small influence on the attractiveness of women. In fact, if a woman was already viewed as attractive, her hair length didn’t really influence how men viewed her in a study by the Scandinavian Journal of Psychology.
HealthyWay
It was women who were rated as plain who were deemed more attractive when shown with long hair.

4. Throw on some red lipstick.

Women have long painted their lips red or added blush to their cheeks to make themselves more appealing to men, but it wasn’t until 2008 that we started to see some published research on the effects of wearing red on human attraction.
HealthyWay
As it turns out, showing a preference for the color red is a behavior exhibited in males throughout the animal kingdom, specifically primates. Homo sapiens, at least according to the findings in this landmark study, were simply following suit, being the animals that they are. (Looks like that charming “you and me baby ain’t nothing but mammals” song that your parents didn’t want you to listen to in middle school was onto something.)
This attraction to the color red appears to be linked to the female cycle, according to the journal Personality and Social Psychology. Researchers observed that female monkeys actually reddened while ovulating and their mates responded to that change.
HealthyWay
Additionally, the same attraction was observed when men were presented with pictures of women wearing red lipstick or a red shirt.
But let’s not get ahead of ourselves. Follow-up research using larger samples has challenged these findings—which honestly makes sense, because when something sounds too good to be true, it probably is. Although it would be wonderful to be able to secure your future with a dreamy guy by throwing on a red dress before you “accidentally” run into him at the library again, this factor alone is unlikely to stir his feelings.
Several more recent studies, like this one published in the journal Social Psychology, closely replicated the 2008 experiment and found that “the red effect” wasn’t actually a thing. Sorry, ladies in red.

5. The Way You Smell

As bizarre as this may sound, men may be attracted to you because of the way you smell. Even though a lot of people know that pheromones are a hormone with a very specific scent, the science behind the attraction isn’t common knowledge.
HealthyWay
Research has found that a woman’s cycle directly influences the pheromones she emits. Depending on where you are in your cycle, men may find you more attractive simply because of the smell of the pheromones you are giving off.

6. Bright and Healthy Eyes

When you ask any man what he finds attractive about a woman, it is almost expected for him to comment on her eyes.
HealthyWay
There is a real reason we place so much emphasis on the eyes of people we’re attracted to, and it isn’t because the eyes are the window to the soul.
Men are more attracted to women with clear, bright eyes, according to The Harvard Brain. It isn’t necessarily about color, either. It is the overall brightness of the entire eye that matters. This is believed to be all about evolution since bright eyes are viewed as healthier, whereas dull or dry eyes are associated with aging.

7. Those Luscious Lips

As silly as it may sound, all those teenagers posting duckface selfies on social media might be onto something, since fuller lips are seen as an attractive trait on women.
HealthyWay
We already know the color of a woman’s lips matters, but that isn’t the only thing that men are looking for in the mouths of a potential love interest.
One Manchester University study found that after meeting a new woman, men spend about half of the interaction looking at their lips. And when it came to the attractiveness of the women they met, men rated women with fuller lips as more attractive.
HealthyWay
The science behind this attraction follows the theme we have been seeing so far—men are attracted to the appearance of health, and full lips are viewed as a physical characteristic of a healthy woman.

8. You sound good to me.

It isn’t all about the way you look. A man’s ears also play a role in determining just how attracted he is to a woman. Just like with males, females’ voices change as they age.
HealthyWay
As their estrogen levels decrease, their tone lowers and deepens. Men are more attracted to women with a higher tone to their voice, according to Smithsonian Magazine. This preference is all about youth, because younger women tend to have higher-pitched voices, and the perception is that a younger woman is healthier (and likely more fertile, with a lower waist-to-hip ratio and fewer pregnancies under her belt).
Of course, men aren’t exclusively dumb animals. Don’t be too quick to assume that any of these physical traits will usher you into eternal romantic bliss or lock you into a life of miserable singledom.
HealthyWay
The way you look, smell, and sound are just a few pieces of the puzzle. The rest of a relationship is just about a couple of bumbling human spirits trying to make sense of this strange world together.

The Strange Ways That We Make Food Last Longer

No refrigeration? No problem. In the famous peat bogs of the United Kingdom, large quantities of butter dating back to 600 B.C. have been unearthed. “Bog butter” was preserved this way because the acidic, cool waters of the bog were ideal to keep food fresh—the original refrigerator.

HealthyWay
By Bazonka – Own work, CC BY-SA 3.0

Fast forward a couple thousand years to the early 20th century, when a man named Clarence Birdseye (of frozen vegetable fame) perfected a “quick freezing” method of preserving fruits and vegetables.

Now you can walk in the frozen food section of the grocery store and purchase virtually any type of food, all thanks to refrigerated food preservation innovation. And it all started with bog butter.

HealthyWay

Even though most of us eat preserved foods every day, how many of us have given any thought to the actual process of how we make food last longer? The moment food is harvested, it begins to spoil. Food preservation is instrumental to human survival.

From ancient bog butter to frozen peas, here are the strangest ways we make food last longer.

Burying

Burying food might seem like an odd way to keep it fresh, but sticking stuff back in the ground is actually a great way to preserve food. Burying food helps keep it fresh by shielding it from sunlight, oxygen, and warm temperatures.

HealthyWay

Before refrigeration was commonplace, cabbages were traditionally buried underground to store them. Some Appalachian farmers still swear that cabbages that have been buried taste sweeter.

Other cultures have customs of burying food as a means of preservation as well. In Greenland, the Inuit still make a traditional delicacy called kiviak, which involves burying a whole seagull sutured inside a sealskin for several months, allowing the meat to ferment.

HealthyWay

Similar to food burial, a root cellar keeps foods, especially root vegetables, fresh for months. Root cellars, like the ground, provide a cool, damp environment ideal for food preservation. The added bonus of a root cellar? Walking downstairs to grab your produce instead of digging up the backyard to figure out where you buried last year’s cabbage crop!

Fermenting

About 7,000 years ago, one lucky person ate some questionable produce, decided it was tasty, and discovered the process of fermentation. Or that’s the theory, anyway. Scientists think that our ancestors stumbled on fermentation—which is essentially controlled decay—by accident.

HealthyWay

When foods are fermented, carbohydrates are converted into alcohol or acids using “good” bacteria.

The awesome thing about fermentation is that you can literally ferment almost anything, and there are numerous health benefits to eating fermented foods.

HealthyWay

Fermented foods such as kombucha contain probiotics (the bacteria that helps keep your digestion regular) and preserve key nutrients in food. The next time you’re thinking of reaching for Activia yogurt in the grocery store, you might want to pick up a jar of sauerkraut instead.

Canning

When you think of France, you probably think about fashion, the Eiffel Tower…and canned vegetables?

Canned vegetables are so ubiquitous on grocery store shelves that you may not consider this a strange method of food preservation at all.

HealthyWay

However, the process of sealing food in pressurized, heat-treated containers didn’t come about until the 18th century, when Napoleon Bonaparte offered a reward to the person who could invent a food preservation method for his men.

Canned foods can be safely eaten for up to several years after they’ve been processed. When foods are heated in jars to a high
temperature, bad bacteria that causes food to spoil is removed.

HealthyWay

At the same time, the heat creates a vacuum seal that prevents air from getting back into the jar. As long as the seal remains unbroken, food stays fresh.

Jellies, Jams, and Aspics

Believe it or not, until fairly recently, the fanciest of fancy foods was essentially meat Jell-O, which is about as delicious as it sounds.

HealthyWay

Aspics are a savory, molded gelatinous dish that usually contains preserved meats inside, much the way Jim preserves Dwight’s desk supplies on The Office. Like other methods on this list, aspics preserve foods by cutting off oxygen, thus preventing spoilage.

Jellies and jams are a much tastier way to preserve many fresh foods, particularly fruits. Although we most often think of fruit jellies, vegetables like peppers and tomatoes (okay, this one is technically a fruit) can also be preserved this way. When a food is made into jelly, the high sugar content and acidity of the fruit help prevent spoilage.

HealthyWay

But unless you also can your jelly jars properly, mold could form on top. Back in the day, people would just scrape the mold off the top and put the rest on their morning toast. Now we know that placing jelly jars in boiling water for a few minutes will vacuum seal them, eliminating the mold risk altogether.

Blast Chilling

Remember Clarence Birdseye? His quick freeze method of preserving vegetables is the precursor to the modern method of blast chilling food preservation. Blast chilling cools food quickly with a blast of fast-moving, icy cold air.

HealthyWay
Alto-Shaam

The benefit of blast chilling is that foods maintain their quality, unlike other frozen foods, which can be watery and tasteless when thawed. In order for food integrity to be maintained, it must be rapidly cooled from temperatures around 158 degrees F to freezing in under 90 minutes.

Because it preserves food fast, blast chilling is used in modern restaurants as a way to prep foods in advance.

HealthyWay

Blast-chilled foods can be quickly thawed and prepared just like fresh foods. For example, Japanese chefs have used blast chilling for years to preserve fresh fish for sushi.

Salt Curing and Dehydration

Most of the methods on this list involve providing the right moisture/oxygen content to safely preserve food. Salt curing is the process of preserving food, usually meat, with large quantities of salt.

HealthyWay
La Quercia

Salt draws the moisture out of food items and prevents spoilage. Salt curing can be done as a dry rub (most often used to preserve ham) or as a brine solution (ideal for preserving cod and other fish).

Dehydration, on the other hand, involves removing all the moisture from foods in order to preserve them. To dehydrate foods, you need heat, dry air, and a source of airflow.

You can safely dehydrate some things in the sun or even in your car if you’re bold. But the easiest (and safest) way to dehydrate large quantities of food is using either your oven or a food dehydrator.

HealthyWay

There’s a reason beef jerky was such a popular trading item on the Oregon Trail. Dehydrated foods don’t need to be refrigerated, last a long time, and are extremely lightweight and easy to store.

Freeze Drying

Freeze drying food is a super technical form of dehydration and really can’t be done at home the way many other food preservation techniques on this list can be.

HealthyWay

When f
ood is freeze dried
, it is in a vacuum chamber, and the temperature is brought to below freezing. This way, the water in the food evaporates from a solid state to gaseous state, preserving the taste and structure of the food but removing the moisture content.

The most popular freeze-dried food is probably astronaut ice cream, but freeze-dried foods can be found in almost every grocery aisle, from cereal to coffee.

HealthyWay
Ruth Hartnup/Flickr

Food scientists have made innovative advances in food preservation, but most of the ways we make food last longer have been around for centuries.

After all, astronauts still eat packets of reconstituted dehydrated foods, proving that those Oregon Trail settlers had the right idea when it comes to making food last longer.

Insane Medical Conditions That Can Just Suddenly Appear

Camille was smart, attractive, and loved her job. Theoretically she had everything going for her—except for an embarrassing and humiliating condition. She smelled like dead fish.

HealthyWay
ABC

This had been a problem since she was a child, when her classmates made fun of how she smelled, and a teacher questioned her hygiene. The odor continued to plague her into adulthood, and people at work complained about it.
She hit her lowest point when she was a teacher and her students started calling her “Ms. Fishy.”
HealthyWay
What’s worse, Camille’s nose doesn’t pick up the scent, so she doesn’t know when the odor intensifies.
Eventually she discovered that she suffers from a bizarre metabolic disorder called trimethylaminuria (TMAU), in which the body secretes excessive amounts of the chemical trimethylamine, which produces the noxious odor.
Although there is continuing research on the topic, the condition is quite rare (only 600 documented cases in the U.S.), so still not much is known about it. There is no cure, only management of symptoms.
HealthyWay
When Camille got in touch with an organization for people with TMAU, she learned she was not alone. She also learned of some steps to take to minimize the intensity of the odor, such as dietary changes, taking chlorophyll, and showering frequently. But for now she and other people with this condition continue to struggle with its effects.
And TMAU is just one of a number of bizarre conditions that have scientists more than a little puzzled.

Pica

If you thought pica was just a unit of measurement, think again. Pica is described by the National Eating Disorder Association as “an eating disorder that involves eating items that are not typically thought of as food and that do not contain significant nutritional value.”
Pregnant women are at a higher risk for developing pica disorder. Instead of craving pickles and ice cream, pica sufferers will crave things like pebbles, soil, soap, and charcoal.
HealthyWay
In one extremely bizarre pica case, a woman ingested furniture polish up to three times a day. Sometimes pica is triggered by a mineral deficiency, but there is usually no underlying cause for the disorder.

Fatal Familial Insomnia

Sonia Vallabh watched her mother struggle to fall asleep for over a year. Eventually, Vallabh’s mother existed in a sort of trance state, somewhere between being fully awake and asleep. She suffered from the rare genetic disorder fatal familial insomnia (FFI), and Vallabh also carries the gene.

HealthyWay
Rose Lincoln/Harvard Staff Photographer

Vallabh doesn’t know when she’ll start developing symptoms. In a race against the clock, she currently researches FFI in hopes of finding a cure.
FFI causes progressive, debilitating insomnia. It is such a rare disorder that there are only 28 family bloodlines in the entire world with the genetic markers for FFI.
Once diagnosed with FFI, patients typically succumb to the disease in a year or less. Vallabh’s mother passed away just months after she began to show symptoms of the disorder. Current research is hopeful, although there is no cure for the sleeplessness that plagues FFI sufferers.

Cold Allergies

Six-year-old Jacob Russell was rushed to the emergency room multiple times when his hands and feet began turning purple for no apparent reason.
Mysteriously, by the time doctors would examine Jacob, his extremities had returned to their normal color. Jacob also experienced allergy symptoms such as hives in the dead of winter, not exactly peak allergy season.

HealthyWay

Finally, the Russells found out that Jacob suffered from from cold urticaria, or an allergy to the cold. Just like allergies to pollen or peanuts, symptoms of cold urticaria range from normal itchy skin and minor swelling to life-threatening anaphylaxis.
In Jacob’s case, temperatures under 50 degrees trigger symptoms. To combat his symptoms, he no longer drinks cold beverages, and his family relocated to Florida for the warmer temperatures.
Unlike seasonal allergies, it’s hard to treat an allergy to cold weather, so treatment focuses on managing symptoms instead.
HealthyWay
iStock

Fortunately, most patients fare quite well after diagnosis by staying away from anything that triggers their symptoms.

Exploding Head Syndrome

Most people drift off to dreamland peacefully, but people with exploding head syndrome (EHS) hear explosive noises when they fall asleep or wake up.
HealthyWay
These noises aren’t associated with pain but can sound like a July 4th fireworks display to those who suffer from the disorder.
The first time you experience EHS can be disorienting, as the noise sounds incredibly real, but it is only happening inside your own head.
HealthyWay
There are many theories about why people suffer from EHS. Some scientists believe EHS is brought on by extreme stress or inner ear issues. Serious cases of EHS have seen improvement with treatment of antidepressants and calcium channel blockers.

Gluten Delusions

Gluten intolerance can cause digestive issues, brain fog, and anemia. But gluten intolerance can also cause one unusual side effect: psychosis. One woman started having unexplained delusions and was finally admitted to a psychiatric hospital, where treatment had little effect.
HealthyWay
Doctors finally suspected the woman had celiac disease but did not connect gluten intolerance to her psychotic break. When the woman was again hospitalized, she was put on a gluten-free diet, and her symptoms improved dramatically.
The relationship between gluten and neurological conditions is still a mystery. When a person suffers from celiac disease, the body views gluten as an invader.
HealthyWay
It’s thought that the body’s inflammatory response to gluten can travel to the brain, causing a whole range of neurological disorders.

Alien Hand Syndrome

Extraterrestrials do not actually come and take over the body of someone suffering from alien hand syndrome (AHS), but it’s pretty close. For those who have AHS, the hand has a life of its own, not unlike Thing from The Addams Family.

AHS actions are totally involuntary and usually take the person suffering from the disorder by surprise.
AHS can occur after certain neurological procedures. Patients do see some improvement in hand control with Botox injections and nerve blocks, although there is no cure for the disorder.

Stendhal Syndrome

Staff at the Uffizi Gallery in Florence, Italy, are accustomed to tourists experiencing panic attack–like symptoms upon viewing the beautiful works of art in the gallery.
These attacks were first recognized by Marie-Henri Beyle in 1817, when he had such a flush of emotions when viewing art in Florence that he fainted.

Beyle, who wrote under the pen name Stendhal, experienced these attacks several times when in the presence of great beauty, thus the syndrome that bears his name today.
Stendhal syndrome is a psychosomatic disorder in which people quite literally have an “art attack.” When viewing scenes of concentrated beauty—as in an art museum—people with Stendhal syndrome experience a wide range of symptoms, including anxiety, heart palpitations, fainting, and even hallucinations.
Upon suffering an attack, people with Stendhal syndrome typically recover quickly. Because the syndrome is brought on by what an individual considers to be beautiful, no two triggers are the same.

Alice in Wonderland Syndrome

“Curiouser and curiouser!” Alice (of Wonderland fame) exclaims after she falls down the rabbit hole. While Alice’s Adventures in Wonderland is a work of fiction, the rare neurological disorder of the same name is very real.

People with Alice in Wonderland syndrome have the illusion that they’ve gotten smaller or larger than the environments where they are. Anyone can develop Alice in Wonderland syndrome, but people who experience migraines are believed to be more susceptible. Fortunately the syndrome doesn’t persist for long and isn’t associated with lasting side effects.

Face Blindness

As a child, Glenn Alperin was unable to tell his brothers apart. He struggled at school to recognize teachers and classmates. Sometimes Alperin even has trouble recognizing his own reflection in the mirror.
He has a rare condition known as face blindness, or prosopagnosia. Because of his condition, almost everyone Alperin meets is a total stranger to him.

People with prosopagnosia “simply fail to develop normal face processing abilities despite normal intellectual and perceptual functions,” according to the Centre for Face Processing Disorders.
There is no cure for face blindness, but it is believed that up to 2 percent of the population could have this disorder. Most patients are able to develop ways of coping with the condition, though. For example, patients might ask loved ones to wear certain identifiable scents or the same hairstyle and clothing.

Foreign Accent Syndrome

Karen Butler went to the dentist for a routine surgery. When she woke up, she no longer spoke with her Midwestern accent. Now Butler speaks with an indeterminate accent that’s vaguely Transylvanian. Her daughter thinks she sounds like a mild-mannered vampire.
Her dentist thought she was just having a hard time coming out of the anesthesia. When the accent persisted long after the drugs wore off, Butler sought medical advice.

It might sound silly, but Butler has the very real, very rare foreign accent syndrome.
Foreign accent syndrome is a neurological disorder that usually arises as the result of a brain injury. The first recorded case of the disorder was in 1941, when a Norwegian woman was hit in the head with a piece of shrapnel and woke from surgery with a German accent. In the years since, there have only been around 100 reported cases.
This benign condition can last for years, and in many cases, patients never revert back to their former accents.
As for Karen Butler, she embraces her new way of speaking, although she feels that the accent has softened a bit over time. Still, she’ll happily oblige when someone asks her to talk like Dracula.
