Don't Worry About Exercising Too Much | Outside Online
The question of whether too much aerobic exercise is bad for your heart was hotly debated for several years after that 2012 study. The Cooper Clinic data, when it was finally published in a peer-reviewed journal more than two years later, had been reanalyzed so that the supposed dangers of too much running disappeared. But by then the idea was firmly implanted in the public mind: marathons are dangerous. (I wrote in depth on this dispute, and how the evidence has shifted, in this 2016 feature.) The topic no longer pops up in the headlines as regularly as it did a few years ago, but it’s still lurking in people’s minds.

Here’s what happened when I quit drinking a year ago - The Washington Post
I sipped my last chilled vodka with lime last September. There wasn’t a lot of pomp when I bid farewell to cocktails. I didn’t want to broadcast my decision because I’d unsuccessfully tried to go long stretches before. Usually I made it a couple of days, maybe a few weeks. When I started this time, I didn’t know how long my booze break would last. Maybe a month, I figured.

That 30 days turned into more than a year. Although I miss the instant relaxation that comes when alcohol hits the bloodstream, I don’t long for what came after: occasional hangovers, interrupted sleep and feeling inexplicably sad when I woke up. I realized I was having a drink or few every day — and although it wasn’t wrecking my life or my health, I wanted to know what would happen if I stopped.

Vitamin D and Fish Oils Are Ineffective for Preventing Cancer and Heart Disease - The New York Times
In recent years, many Americans have embraced vitamin D and fish oil pills, their enthusiasm fueled by a steady trickle of suggestive research studies linking higher levels of vitamin D with lower rates of cancer and other ills, and fish consumption with reduced heart disease.

Now a large and rigorous government-funded randomized trial — the only such study of omega-3 fish oils ever carried out in healthy adults, and the largest trial ever done of high-dose vitamin D — has found the supplements do not lower cancer rates in healthy adults. Nor do they reduce the rate of major cardiovascular events, a composite of heart attacks, strokes and deaths from cardiovascular disease. The trial is of the kind considered the gold standard in medicine.

What Happened When I Started Intuitive Eating | A Cup of Jo
But I didn’t know any other way. I needed some kind of diet deprogramming, but did that even exist? As it turned out, yes. It’s called intuitive eating.

That’s how I describe intuitive eating when someone asks me what it is. It’s not a new concept; the anti-diet has been around pretty much since the diet. Dietitians Elyse Resch and Evelyn Tribole were among the first to turn it into an actual program, which they laid out in their book, Intuitive Eating (first published in 1995, followed by two later editions). Intuitive eating was soon adopted by a number of nutrition professionals (and eating disorder treatment programs), but still, it’s the kind of mystical-sounding phrase that often raises eyebrows — which tend to shoot up even higher when I explain the fundamentals. In intuitive eating, you can (and should) eat whatever you want. There are no good or bad foods, no points, no goal weight — no focus on weight whatsoever. The point is to eradicate all those judgments and emotional hang-ups we’ve attached to eating, and learn to see food as just food again. Perhaps even crazier, you learn to trust yourself to make your own choices. Everything is on the table.

Speaking while exercising? Not if you want to get fitter - The Globe and Mail
The Queen’s researchers have a surprisingly simple suggestion, which they tested in a separate experiment: “We also found that prescribing exercise at an intensity where participants could not speak comfortably resulted in consistently high blood lactate responses,” Bonafiglia said.

This approach, known as the Talk Test, involved asking participants to count to 30 at “a regular conversational pace and volume” while cycling. If they could do it comfortably, they were asked to speed up slightly until it began to get difficult.

And that’s pretty much it.

In an age of pervasive fitness technology and self-monitoring, there’s some irony in the triumph of mere conversation as a more sensitive barometer of exercise intensity than the expensive gold-standard laboratory approach. But it’s also a reminder of an unvarnished truth that athletes have always known: To get fitter, you have to work hard, no matter what your wearable tech tells you.

Early Time-Restricted Feeding Improves Insulin Sensitivity, Blood Pressure, and Oxidative Stress Even without Weight Loss in Men with Prediabetes: Cell Metabolism
•Early time-restricted feeding (eTRF) increases insulin sensitivity
•eTRF also improves β cell function and lowers blood pressure and oxidative stress
•eTRF lowers the desire to eat in the evening, which may facilitate weight loss
•Intermittent fasting can improve health even in the absence of weight loss
Intermittent fasting (IF) improves cardiometabolic health; however, it is unknown whether these effects are due solely to weight loss. We conducted the first supervised controlled feeding trial to test whether IF has benefits independent of weight loss by feeding participants enough food to maintain their weight. Our proof-of-concept study also constitutes the first trial of early time-restricted feeding (eTRF), a form of IF that involves eating early in the day to be in alignment with circadian rhythms in metabolism. Men with prediabetes were randomized to eTRF (6-hr feeding period, with dinner before 3 p.m.) or a control schedule (12-hr feeding period) for 5 weeks and later crossed over to the other schedule. eTRF improved insulin sensitivity, β cell responsiveness, blood pressure, oxidative stress, and appetite. We demonstrate for the first time in humans that eTRF improves some aspects of cardiometabolic health and that IF’s effects are not solely due to weight loss.

The Big-Five Workout Program | - Notes
This program is based on the book “Body By Science” from Doug McGuff and John Little. The program is like a mutual fund of exercises, this means basically you need nothing more than these exercises. It is the best starting point and a ideal fundament to stimulate all of the metabolic benefits necessary to optimize human health and fitness. It is very simple and it’s done in less than 13 minutes a week.

You can do the workout with machines or as a free weight option.  However given that it is basically a resistance training, which means that the goal of your training is a point where you can no longer produce enough force to lift the resistance, the machine option is the better choice.

Weight Training Is the Best Exercise for Bone Strength |
For many, weight training calls to mind bodybuilders pumping iron in pursuit of beefy biceps and bulging pecs. But experts say it’s well past time to discard those antiquated notions of what resistance training can do for your physique and health. Modern exercise science shows that working with weights—whether that weight is a light dumbbell or your own body—may be the best exercise for lifelong physical function and fitness.
“To me, resistance training is the most important form of training for overall health and wellness,” says Brad Schoenfeld, an assistant professor of exercise science at New York City’s Lehman College. During the past decade, Schoenfeld has published more than 30 academic papers on every aspect of resistance training—from the biomechanics of the push-up to the body’s nutrient needs following a hard lift. Many people think of weight training as exercise that augments muscle size and strength, which is certainly true. But Schoenfeld says the “load” that this form of training puts on bones and their supporting muscles, tendons and ligaments is probably a bigger deal when it comes to health and physical function.

How Could the Sodium You Eat Affect Your Weight?
Conventional wisdom has long held that salty foods boost our thirst and lead us to drink more water. But can salt also lead us to eat more, as well?

Researchers have begun to explore salt’s previously unknown role in hunger and weight gain. Several recent studies shed light on why salt may encourage us to overeat.

“Until now, we have always focused on the effect of salt on blood pressure,” says Jens Titze, MD, associate professor of medicine and of molecular physiology and biophysics at Vanderbilt University in Nashville. “We have to expand our conceptions of salt and diet.”

The Best Thing to Eat Before a Workout? Maybe Nothing at All - The New York Times
There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories, on average, during the workout after breakfast than after fasting.

But it was the impacts deep within the fat cells that may have been the most consequential, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins that can improve blood sugar regulation and insulin levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.

The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first, says Dylan Thompson, the director of health research at the University of Bath and senior author of the study.

Maybe moderate drinking isn't so good for you after all
We generally assume moderate drinking (two standard drinks per day) is good for our health.

This idea comes from studies over the past three decades showing moderate drinkers are healthier and less likely to die prematurely than those who drink more, less, or don’t drink at all.

I would be glad if this were true.

But our latest research challenges this view. We found while moderate drinkers are healthier than relatively heavy drinkers or non-drinkers, they are also wealthier. When we control for the influence of wealth, then alcohol’s apparent health benefit is much reduced in women aged 50 years or older, and disappears completely in men of similar age.

Neurokirurg: Kontraproduktivt demonisera cyklister utan hjälm
– Folk kan också inbilla sig att det är väldigt farligt att cykla och att det är idioti att inte använda hjälm – när det inte finns vetenskapliga bevis för någotdera, säger Jari Siironen.

Siironen sitter med i en God medicinsk praxis-arbetsgrupp för vård av hjärnskador där han tilldelats ansvaret för hjälmar. Han anser att ett hjälmtvång vore till mer skada än nytta, eftersom det skulle göra cyklismen mindre lockande. Särskilt kunde det ha en negativ effekt på folk som cyklar då och då.

Till skillnad från den bild upplysningskampanjerna målar upp, är hjärnskador ganska ovanliga bland cyklister i Finland. Finsk statistik visar att hälften av hjärnskadorna sker bland fotgängare av vilka största delen är berusade.

– Om spriten tog slut i världen, skulle jag bli arbetslös. Om cykelskadorna försvann, skulle jag inte ens märka det, säger Siironen.

Cykelhjälmar skyddar mot ytliga sår och skrapor och Siironen uppmuntrar folk att använda hjälm, men han poängterar att lätta cykelhjälmar inte alls ger ett så bra skydd mot hjärnans rörelser som sker inuti skallen vid fall.

High-intensity interval training rapidly improves diabetics' glucose metabolism -- ScienceDaily
New research reveals that high-intensity interval training (HIIT) increases glucose metabolism in muscles as well as insulin sensitivity in type 2 diabetes. After just a two-week training period, the glucose uptake in thigh muscles returned to a normal level.

"It's particularly good news that when it comes to the glucose metabolism and endurance it does not seem to matter in whether the exercise takes place over a longer period of time as moderate training or over a short period as high-interval training. Everyone can choose the type of training that suits them best. In general, you can achieve the best results for you body by using both training methods," encourages Sjöros.

Supplement Goals Reference |
If you've found this page, then you're probably looking to find out the truth about supplements - which work, and which don't . You know that supplements can help, but you don't know who to trust. Everywhere you turn, you're overwhelmed with companies promising you the latest and the greatest.

For the past five and a half years, we've been trudging through thousands and thousands of peer-reviewed scientific studies so that we can thoroughly understand supplements. Having analyzed over 33,000 individual studies, we've come to learn what works (and what doesn't).

Now, before we go any further, it's important to note: we are NOT here to sell you supplements. We don't own a line of supplements that we will steer you towards.

Beyond that, we're not in cahoots with anyone that does. In fact, we make NO brand recommendations. We make NO product recommendations. All we do is make sense of scientific research on supplementation and nutrition.

We've been compiling this research for a long time, and our Supplement-Goals Reference Guide puts it all together in an easy-to-use manner. You simply look up whichever supplement (eg "Vitamin D") or health goal (eg "blood glucose") you're interested in, and you will instantly know which supplements work (and which don't). Our guide literally solves all your supplement confusion.

Why Running Helps Clear Your Mind -- Science of Us
A good run can sometimes make you feel like a brand-new person. And, in a way, that feeling may be literally true. About three decades of research in neuroscience have identified a robust link between aerobic exercise and subsequent cognitive clarity, and to many in this field the most exciting recent finding in this area is that of neurogenesis. Not so many years ago, the brightest minds in neuroscience thought that our brains got a set amount of neurons, and that by adulthood, no new neurons would be birthed. But this turned out not to be true. Studies in animal models have shown that new neurons are produced in the brain throughout the lifespan, and, so far, only one activity is known to trigger the birth of those new neurons: vigorous aerobic exercise, said Karen Postal, president of the American Academy of Clinical Neuropsychology. “That’s it,” she said. “That’s the only trigger that we know about.”

Intermittent fasta och styrketräning
Intermittent fasta är ett ämne som har varit populärt att diskutera i flera år nu även om dess popularitet verkar gå lite i vågor. Personligen upplever jag i alla fall att det snackades mer om det för kanske 4-5 år sen för att sen lugna ner sig lite, och sen fick det lite ny fart samtidigt som 5:2-dieten slog igenom vilket faktiskt även det är en typ av intermittent fasta.

När det gäller styrketräning och intermittent fasta här i Sverige så är det dock ingen tvekan om att det är Martin Berkhans leangains där du äter under 8 timmar och fastar 16 varje dag som har varit och fortfarande är störst.

Det är heller ingen tvekan om att det upplägget har fungerat väldigt bra för många. Om man söker runt på nätet så finns det folk som påstår att det skulle vara en väldigt dålig idé att äta enligt leangains om man försöker bygga muskler med motiveringen att du är katabol under för lång tid. De som påstår att effekten skulle vara så dramatisk verkar dock inte ha funderat kring att det är uppenbart att många faktiskt får väldigt bra resultat. Så det är ingen tvekan om att upplägget kan fungera väldigt bra.

Om det skulle vara bättre eller sämre än andra upplägg kommer därför att handla mer om små skillnader. Utöver ordentlig styrketräning, tillräckligt med protein, tillräckligt med sömn och en hyfsad koll på kaloriintaget så finns det med största sannolikhet inte någonting som du själv kan kontrollera som har en särskilt betydande effekt på dina resultat.

Studiemässigt är det tyvärr dåligt med studier på människor och de som finns har vanligen handlat om studier där man fokuserat på viktnedgång hos feta personer. Man har inte inkluderat någon träning och oftast har det varit 5:2 eller liknande upplägg med en mer långvarig fasta eller en period med väldigt lågt kaloriintag följt av en period med ”normalt” kaloriintag.

För ungefär en vecka sen publicerades dock äntligen en studie med ett upplägg väldigt likt leangains där man dessutom använde sig av redan tränade personer (1). Det är alltså en studie som faktiskt kan ge en början till ett svar på om det finns några mindre fördelar eller nackdelar med intermittent fasta á la leangains kontra att äta lite när som helst.

How to Build Muscle 💪🏼
This guide is the result of one year's research into what modern science proves is the most efficient way to build muscle. It's for both men and women.

I wrote this guide because — even in 2016 — much of the casual weightlifting advice is unsubstantiated and misleading. I can't blame most bloggers for it, because many of the facts in this guide has not been broadly published outside of scientific literature. 

This guide contradicts much of the popular bodybuilding recommendations, including the myth that women have a harder time gaining beginner muscle, that exercise rest times should be kept to 1–3 minutes, that you have to regularly switch up your exercises, that machine exercises are less effective than barbell ones, and so on.

Throughout this guide, I consistently support my claims by citing studies and showing you how to measure your weekly gains so you can confirm you're growing.

Closest Thing to a Wonder Drug? Try Exercise - The New York Times
After I wrote last year that diet, not exercise, was the key to weight loss, I was troubled by how some readers took this to mean that exercise therefore had no value.

Nothing could be further from the truth. Of all the things we as physicians can recommend for health, few provide as much benefit as physical activity.

In 2015, the Academy of Medical Royal Colleges put out a report calling exercise a “miracle cure.” This isn’t a conclusion based simply on some cohort or case-control studies. There are many, many randomized controlled trials. A huge meta-analysis examined the effect of exercise therapy on outcomes in people with chronic diseases.

Is Gluten Sensitivity Really a Carb Issue? | University of Michigan
Functional bowel disorder is an umbrella term used to describe glitches in how your stomach and bowels function or work. Patients with FBDs may have symptoms such as nausea, bloating, stomach pain, diarrhea and constipation.

Unlike patients with inflammatory bowel disease (IBD), who may exhibit similar symptoms, the organs and digestive tract of an FBD patient may be appear normal on tests such as endoscopy and blood work. FBDs are very common and include irritable bowel syndrome and functional dyspepsia.

Patients with FBD do not experience any nutritional deficiencies because of absorption issues in the gastrointestinal tract, but they very often have restricted their food intake to the point that they are no longer eating a well-balanced diet.

Because FBD patients can experience gastrointestinal distress when eating specific foods, these patients start eliminating those foods from their diet. The problem is that without careful consideration and guidance, this self-restricted diet most likely eliminates more foods than necessary.

A careful nutrition plan, developed with assistance from your health care provider, can help address these issues.

Superfoods List: Best Foods That Burn Fat & Help You Lose Weight
Ohhh, that’s right. Because superfoods are fucking bullshit.

You see, back here in reality…

There is no single food that will cause you to lose fat.
There is no single food that will prevent you from gaining fat.
There is no single food that will cause you to build muscle.
There is no single food that will make you healthy.
There is no single food that will prevent or cure a disease.
There is no single food that will make up for an inadequate overall diet or workout program.
And no, there is no combination of different supposedly “special” foods that you can include together in your diet that will make any of these things happen, either.

The truth is, you could scour the Earth to locate every superfood that has ever been included on every one of these stupid useless lists and then proceed to consume all of them every single day for the rest of your life. And guess what?

You could still very easily be a fat (even obese… even morbidly obese), un-muscular, unhealthy person with numerous diseases and medical issues.

En samlad expertkår har i flera års tid kallat detox för nonsens, med argument om att kroppen renar sig själv, men ändå fortsätter detoxtrenden att växa med nya produkter.

Bild: Lotta-Karin Klinge Härberg
– Levern och njurarna har som funktion att rena kroppen hela livet, och man kan liksom inte ”hjälpa till” där. Att dricka gröna juicer gör inget extra för din lever, säger Lotta-Karin Klinge Härberg som jobbar som verksamhetschef på dietistkliniken vid Karolinska universitetssjukhuset.

Ur näringssynpunkt är det betydligt mer intressant att vända på idén och tänka att man ska bygga upp kroppen.
Hon menar att det som ställer till det är själva begreppet ”detox”.

– De flesta som pratar om att göra en detox menar nog inte att de ska avgifta sig från toxiner. Det handlar mer om att man vill ha en nystart, att bryta med dåliga vanor, och det är det verkligen inget fel med, säger Lotta-Karin Klinge Härberg, men understryker att du inte kan rensa ut toxiner genom att dricka juice i ett par veckor.

– Ur näringssynpunkt är det betydligt mer intressant att vända på idén och tänka att man ska bygga upp kroppen med nyttiga juicer och grönsaker.

For generations, Icelandic babies have napped outside in freezing temperatures - Quartz
Reykjavík’s biggest shopping street fills with babies sleeping in their strollers in summer. They’re there in the winter, too, napping in sub-zero temperatures. If they’re not on the street, they’re on balconies or in the backyard, while their parents huddle over hot tea indoors.
The custom of wheeling your baby outside to sleep is such a big deal in Iceland that Icelanders who live in big apartment buildings sometimes keep a special carriage on the balcony—for napping only.
“Icelanders live more than 10 years longer than the global average.”
But why? For a long time, indoor sleeping conditions simply weren’t that great. With poor air circulation and overcrowded living conditions, traditional Icelandic homes were muggy and sometimes smoky from cooking.
In the beginning of the 20th century, a tuberculosis epidemic shook the nation. Around the same time, the baby stroller became available in Iceland, finally widely manufactured and globally available after its invention in the UK almost 200 years earlier. In 1926, Dr. David Thorsteinsson published a pedagogy book in Iceland arguing for the benefits of outdoor life and fresh air to strengthen children’s immune systems.

The benefits of letting babies sleep in sub-zero temperatures - BBC News
Would you put your baby outside in the freezing cold for their lunchtime nap?
In Finland and other Nordic countries, it is a completely normal part of raising a child and is widely believed to improve health.
The practice started in the 1940s when child mortality was high and air quality in the home was poor.
It was thought that the sunshine and fresh air would prevent rickets and increase immunity against bacteria.
Although child health has improved considerably during the intervening decades, research shows that there are still benefits to embracing the cold.
Doctors warn, however, that sleeping in the cold may not be suitable for everyone, and that babies should be suitably dressed for cold weather.

The babies who nap in sub-zero temperatures - BBC News
Would you put your baby or toddler outside in the freezing cold for their lunchtime nap? Most Nordic parents wouldn't give it a second thought. For them it's part of their daily routine.
Daytime temperatures this winter in Stockholm have regularly dropped to -5C (23F) but it's still common to see children left outside by their parents for a sleep in the pram.
Wander through the snowy city and you'll see buggies lined up outside coffee shops while parents sip on lattes inside.
And if you are visiting friends and your child needs a nap, you may be offered the garden or balcony instead of a bedroom.
"I think it's good for them to be in the fresh air as soon as possible," says Lisa Mardon, a mother-of-three from Stockholm, who works for a food distribution company.

Socker & barn - Usla studier hyllas om resultatet är "rätt"
För två dagar sen publicerades en studie utförd av Robert Lustig som föga förvånande fått stor uppmärksamhet i olika större medier igår och idag. Robert Lustig är det nog en hel del som känner till även här i Sverige då hans föreläsning och påståenden kring fruktos fått extremt stor spridning med tanke på dess ämne och han är ju även väldigt hyllad inom LCHF. Hans påståenden kring socker och då främst fruktos har däremot blivit ganska ordentligt ifrågasatta från väldigt många eftersom han varit väldigt alarmistisk i sina påståenden.

Den studie som Lustig med flera har publicerat nu har titel, ”Isocaloric fructose restriction and metabolic improvement in children with obesity and metabolic syndrome” men tyvärr lovar titeln lite mer än vad studien i sig levererar som jag kommer gå igenom senare. Men först en liten kort genomgång av vad studien påstår sig visa och som vad medierna har skrivit om den.

Sugar isn’t just making us fat, it’s making us sick - Quartz
The children had eaten the same number of calories and had not lost any weight, and yet every aspect of their metabolic health improved. With added sugar cut out of their diet for 10 days, blood pressure, triglycerides, low-density lipoprotein (LDL, or “bad cholesterol”), insulin sensitivity and glucose tolerance all improved. And remember, we weren’t giving them just leafy greens and tofu—we fed the kids processed foods, just ones without sugar.
Further studies are needed to see if this will also work in adults, and if the benefits are short-term or long-term.
Sugar is like alcohol

This study demonstrates that a calorie is not a calorie, and that sugar is a primary contributor to metabolic syndrome, unrelated to calories or weight gain. By removing added sugar, we improved metabolic health.
Sugar may not be the only contributor to chronic disease, but it is far and away the easiest one to avoid. Kids could improve their metabolic health—even while continuing to eat processed food—just by dumping the sugar. Can you imagine how much healthier they’d be if they ate real food?

What You Can Learn From Hunter-Gatherers' Sleeping Patterns - The Atlantic
Here’s the story that people like to tell about the way we sleep: Back in the day, we got more of it. Our eyes would shut when it got dark. We’d wake up for a few hours during the night instead of snoozing for a single long block. And we’d nap during the day.

Then—minor key!—modernity ruined everything. Our busy working lives put an end to afternoon naps, while lightbulbs, TV screens, and smartphones shortened our natural slumber and made it more continuous.

All of this is wrong, according to Jerome Siegel at the University of California, Los Angeles. Much like the Paleo diet, it’s based on unsubstantiated assumptions about how humans used to live.

Siegel’s team has shown that people who live traditional lifestyles in Namibia, Tanzania, and Bolivia don’t fit with any of these common notions about pre-industrial dozing. “People like to complain that modern life is ruining sleep, but they’re just saying: Kids today!” says Siegel. “It’s a perennial complaint but you need data to know if it’s true.”

First described in 1989 by David Strachan, a London-based epidemiologist, the idea is that people exposed to a diversity of microorganisms early in life lower their risk of allergic diseases like asthma, eczema, seasonal allergies, and even autoimmune disorders such as arthritis or inflammatory bowel disease.

The logic of the hygiene hypothesis is pretty alluring: "A child's immune system needs education," Erika von Mutius, a pediatric allergist at the University of Munich, recently told my colleague Joseph Stromberg. "The hygiene hypothesis suggests that early life exposure to microbes helps in the education of an infant's developing immune system." That's why places like farms, or even houses with pets, are thought to have some protective effect against allergies for kids.

That said, scientists haven't yet proved the hygiene hypothesis. It's still just that — a hypothesis. And even if it's true, it's a lot less sweeping than a lot of people tend to think.

Expensive running shoes don't prevent injuries, but comfortable ones might
But where does that leave people faced with the task of deciding the right shoe for them? Interestingly, the solution may lie in not what you think the shoes may do for you, but how comfortable they feel.

In the absence of strong evidence that modern running shoe features reduce injury rates, comfort may be more important than other factors, such as reduced foot pronation and shoe cushioning.

Although footwear comfort is difficult to define and quantify, most people are able to sense whether the shoes they’re trying on are comfortable or not. Support, fit and foot alignment are among factors that influence feeling comfortable in a pair of shoes.

Comfortable running shoes are associated with lower frequency of injuries than uncomfortable shoes. This suggests your body may be the best judge of footwear that’s ideal for you.

The next time you feel bamboozled by the cornucopia of gels, foams and rubbers in running shoes, arm yourself with the knowledge that comfort is one of the best determinants of whether a pair of shoes is right for you. And that may work best for preventing injuries, your wallet and your peace of mind.

Slipping Away | Maclean's Magazine
That Christmas, Joël Aubin was 36 years old and already battling hard to work around an erosion process that was hard-wired into every cell of his body. He had dominantly inherited Alzheimer’s disease, the result of a genetic mutation that snakes through family trees. The disease itself is rare, and Jo is a nearly unheard-of aberration because of his age. He wouldn’t know he had the disease for another 18 months—but he’d seen it all before: His mother was 47 when she died of the same illness. Jo’s teenage world had been ripped from its frame then, but he had grown up with no idea that he had a 50/50 chance of inheriting the same fate. Alzheimer’s disease would fray his marriage before fundamentally changing it, shrink Jo’s world to the size of his neighbourhood and forge his friends and family into a tight support system. And it would lead Jo to resolve to avoid a long goodbye like his mother’s, and to choose when his story would end.

The dominantly inherited form of the disease is said to account for fewer than one per cent of Alzheimer’s cases—Jo’s specialist pegs it at much rarer than even that—and it’s caused by a mutation in one of three genes. While the more common type of Alzheimer’s carries a genetic risk component that means certain people are more likely to develop the disease, this genetic mutation is different: For an unlucky few like Jo, it’s a terrible guarantee. These people overproduce a protein called beta-amyloid, which accumulates in their brains as “plaques,” while another protein called tau twists itself into “tangles” inside the nerve cells. Together, they strangle neurons and eventually consume memory and ability as the brain withers.

People with these genetic mutations usually show symptoms around the same age as their parents. A 2012 study published in the New England Journal of Medicine traced the insidious groundwork of the disease through “biomarkers” detectable in the body long before symptoms surfaced. Twenty-five years before Jo would have noticed any major cognitive problems, the levels of amyloid in his cerebrospinal fluid would have begun to decline, as the protein began to accumulate in his brain. Jo would have been about 10 years old.

To Thrive, Many Young Female Athletes Need A Lot More Food : Shots - Health News : NPR
Participation in sports by girls and young women has soared in recent decades — by 560 percent among high school students since 1972, and 990 percent among college students, according to the Women's Sports Foundation. Highly committed young female athletes now run track and play soccer, basketball, water polo and other demanding sports that require strong bodies.

But many girls aren't eating enough to satisfy the physical demands of those sports, scientists say, and that's putting them at risk for health problems that can last a lifetime.

These athletes are essentially malnourished. The danger they face is called female athlete triad syndrome because it typically includes three symptoms: irregular menstrual cycles, low energy and low bone density.

Water can be disinfected and in this way made drinkable using the rays of the sun. "Solar water disinfection" - SODIS for short - thus offers a solution for preventing diarrhoea, one of the most common causes of death among people in developing countries.

Clean drinking water in 6 hours
The SODIS method is ideal for treating water for drinking in developing countries. All it requires is sunlight and PET bottles. How does it work? Clear PET bottles are filled with the water and set out in the sun for 6 hours. The UV-A rays in sunlight kill germs such as viruses, bacteria and parasites (giardia and cryptosporidia). The method also works when air and water temperatures are low.

People can use the SODIS method to treat their drinking water themselves. The method is very simple and its application is safe. It is particularly suitable for treating relatively small quantities of drinking water.

Put Down The Q-Tip: You've Been Cleaning Your Ears All Wrong | Greatist
As much as we love that so fresh, so clean feeling, if you have any willpower, wean yourself off cotton swabs. They do much more harm than good, and excessive ear cleaning will almost certainly land you in the doctor's office, says Leon Chen, M.D., an ear, nose, and throat doctor at Manhattan's ENT and Allergy Associates. While you may see a satisfying bit of yellow on the cotton bud, chances are you're actually pushing most of the wax deeper into your ear canal, past where it's naturally produced (and ideally should stay).

Earwax also holds antibiotic and antifugal properties, and too much cleaning can lead to ear and skin complications down the road, from ear infections to eczema in the outer ear, says Dale Tylor, M.D., a pediatric and general otolaryngologist at Washington Township Medical Foundation in Fremont, CA. Even more concerning, she adds it's pretty common to see patients who've poked a hole through their eardrum after using cotton swabs.

But we're not exactly known for our willpower. So if you really, truly can't cut it cold turkey, limit your cleaning to three times per month, Tylor says. To avoid any Horvath-like mishaps, only clean after a shower since the heat causes the wax to melt. Line up a fingernail at the point where the cotton meets the Q-tip stick--this will be your safeguard to make sure you don't go too deep. Gently wipe inside your ear, and try not to obsess over whether there's any earwax left.

Scientists have discovered a simple way to cook rice that dramatically cuts the calories - The Washington Post
Rice is popular because it's malleable—it pairs well with a lot of different kinds of food—and it's relatively cheap. But like other starch-heavy foods, it has one central flaw: it isn't that good for you. White rice consumption, in particular, has been linked to a higher risk of diabetes. A cup of the cooked grain carries with it roughly 200 calories, most of which comes in the form of starch, which turns into sugar, and often thereafter body fat.

But what if there were a simple way to tweak rice ever so slightly to make it much healthier?

An undergraduate student at the College of Chemical Sciences in Sri Lanka and his mentor have been tinkering with a new way to cook rice that can reduce its calories by as much as 50 percent and even offer a few other added health benefits. The ingenious method, which at its core is just a simple manipulation of chemistry, involves only a couple easy steps in practice.

NEAT way to get in shape - Chicago Tribune
Catch-22. We want to lose weight, but we don't want to exercise. 

The solution may not require much sweating. I want to tell you about a neat way to burn calories. Make that a NEAT way. This stands for nonexercise activity thermogenesis, which is scientist speak for "moving around doing stuff that is not sport or exercise." 

Your mission, should you choose to accept it, is not to exercise, but to be physically active. It is not only a lot easier to accept this mission than you think, but it can be a more effective weight-loss tool than regular trips to the gym. 

How is it more effective? Because NEAT has the potential to burn substantially more calories per day than exercise for the average person.

The Cardio Vs. Weights Cheat Sheet | Body for Wife
Any time you move your ass you’re doing cardio.

Weightlifting works your heart and lungs too, duh. A better term for what people refer to as “doing cardio” is “aerobic training.” But since I’m not totally anal, I’ll mostly stick with the common vernacular.

This is all about weights vs. cardio, like you only have one choice, and no one has ever decided that maybe they could do both, or something.

Each has its own merits, but a lot of the debate has to do with body composition, so in any analysis that compares the two it is critical to also analyze the effect these two forms of exercise have on diet.

Simple Rules for Healthy Eating -
Over the past few months, I’ve written a number of times on how nutrition recommendations are seldom supported by science. I’ve argued that what many people are telling you may be inaccurate. In response, many of you have asked me what nutrition recommendations should say.

It’s much easier, unfortunately, to tell you what not to do. But here at The Upshot, we don’t avoid the hard questions. So I’m going to put myself on the line. Below are the general rules I live by. They’re the ones I share with patients, with friends and with family. They’re the ones I support as a pediatrician and a health services researcher. But I acknowledge up front that they may apply only to healthy people without metabolic disorders (me, for instance, as far as I know).

These suggestions are also not supported by the scientific weight of rigorous randomized controlled trials, because little in nutrition is. I’ve inserted links to back them up with the available evidence. They are not “laws” and should not be treated as such. No specific nutrients will be demonized, and none will be held up as miracles. But these recommendations make sense to me, and they’ve helped me immensely.

How Successful People Stay Calm — Medium
Research from the University of California, Berkeley, reveals an upside to experiencing moderate levels of stress. But it also reinforces how important it is to keep stress under control. The study, led by post-doctoral fellow Elizabeth Kirby, found that the onset of stress entices the brain into growing new cells responsible for improved memory. However, this effect is only seen when stress is intermittent. As soon as the stress continues beyond a few moments into a prolonged state, it suppresses the brain’s ability to develop new cells.

“I think intermittent stressful events are probably what keeps the brain more alert, and you perform better when you are alert,” Kirby says. For animals, intermittent stress is the bulk of what they experience, in the form of physical threats in their immediate environment. Long ago, this was also the case for humans. As the human brain evolved and increased in complexity, we’ve developed the ability to worry and perseverate on events, which creates frequent experiences of prolonged stress.

Besides increasing your risk of heart disease, depression, and obesity, stress decreases your cognitive performance. Fortunately, though, unless a lion is chasing you, the bulk of your stress is subjective and under your control. Top performers have well-honed coping strategies that they employ under stressful circumstances. This lowers their stress levels regardless of what’s happening in their environment, ensuring that the stress they experience is intermittent and not prolonged.

While I’ve run across numerous effective strategies that successful people employ when faced with stress, what follows are ten of the best. Some of these strategies may seem obvious, but the real challenge lies in recognizing when you need to use them and having the wherewithal to actually do so in spite of your stress.

Free Divers Are Rewriting the Physiology of the Body—Underwater
“It certainly shocked the scientific community,” said Claes Lundgren, one of the world’s leading experts on respiratory and hyperbaric medicine, and the former director of the University of Buffalo’s Center for Research and Education in Special Environments. “It was remarkable that they could go that deep.” At 330 feet down, the water pressure is roughly 11 atmospheres, Lundgren explains. In other words, the pressure pushing in on the lungs was increased to 11 times normal.

Nor was the repudiation of Boyle’s Law the only piece of dogma overturned by this brash new breed of sportsmen. When scientists began to calculate the amount of oxygen in the lungs of these free divers, and compare it to the amount that it was believed a diver would need to survive under water for any length of time, the numbers didn’t add up. Somehow, those participating in the new sport were surviving underwater with far less air for far longer than anyone had thought possible. All of which led scientists like Lundgren to ask the obvious question. What on Earth could be going on?

Human beings, it turns out, have been gifted with a series of underwater survival mechanisms so powerful that some scientists now argue they were almost certainly forged on the crucible of natural selection.

Food Rules From Michael Pollan Worth Following -
In his last book, Mr. Pollan summarized his approach in just seven words: “Eat food. Not too much. Mostly plants.” The new book provides the practical steps, starting with advice to avoid “processed concoctions,” no matter what the label may claim (“no trans fats,” “low cholesterol,” “less sugar,” “reduced sodium,” “high in antioxidants” and so forth).

As Mr. Pollan puts it, “If it came from a plant, eat it; if it was made in a plant, don’t.”

Do you already avoid products made with high-fructose corn syrup? Good, but keep in mind, sugar is sugar, and if it is being added to a food that is not normally sweetened, avoid it as well. Note, too, that refined flour is hardly different from sugar once it gets into the body.

Also avoid foods advertised on television, imitation foods and food products that make health claims. No natural food is simply a collection of nutrients, and a processed food stripped of its natural goodness to which nutrients are then added is no bargain for your body.

Those who sell the most healthful foods — vegetables, fruits and whole grains — rarely have a budget to support national advertising. If you shop in a supermarket (and Mr. Pollan suggests that wherever possible, you buy fresh food at farmers’ markets), shop the periphery of the store and avoid the center aisles laden with processed foods. Note, however, that now even the dairy case has been invaded by products like gunked-up yogurts.

Follow this advice, and you will have to follow another of Mr. Pollan’s rules: “Cook.”

“Cooking for yourself,” he writes, “is the only sure way to take back control of your diet from the food scientists and food processors.” Home cooking need not be arduous or very time-consuming, and you can make up time spent at the stove with time saved not visiting doctors or shopping for new clothes to accommodate an expanding girth.

At some start-ups, Friday is so casual that it’s not even a workday - The Washington Post
Carson, who is originally from Colorado, started his first company in 2004 in the U.K., thinking it would give him more freedom with his time. But he soon found himself working that same intense pace until his wife asked him why he was working more and making less. She suggested taking Fridays off.

“At first, I thought, ‘This is insane; We’ve got way too much work to do,’ ” Carson said. “But the more I thought about it, really, running your own company is about creating your own universe. So why not create a universe you’d want to live in? That’s when the idea went from stupid and crazy to, maybe we should actually do that. So we tried it one week, and never looked back.”

Google got it wrong. The open-office trend is destroying the workplace. - The Washington Post
These new floor plans are ideal for maximizing a company’s space while minimizing costs. Bosses love the ability to keep a closer eye on their employees, ensuring clandestine porn-watching, constant social media-browsing and unlimited personal cellphone use isn’t occupying billing hours. But employers are getting a false sense of improved productivity. A 2013 study found that many workers in open offices are frustrated by distractions that lead to poorer work performance. Nearly half of the surveyed workers in open offices said the lack of sound privacy was a significant problem for them and more than 30 percent complained about the lack of visual privacy. Meanwhile, “ease of interaction” with colleagues — the problem that open offices profess to fix — was cited as a problem by fewer than 10 percent of workers in any type of office setting. In fact, those with private offices were least likely to identify their ability to communicate with colleagues as an issue. In a previous study, researchers concluded that “the loss of productivity due to noise distraction … was doubled in open-plan offices compared to private offices.”

Yale Scientific Magazine – Does Sugar Really Make Children Hyper?
In 1982, the National Institute of Health announced that no link between sugar and hyperactivity had been scientifically proven. Why, then, does this myth still persist? It may be mostly psychological. As previously stated, experimentation has shown that parents who believe in a link between sugar and hyperactivity see one, even though others do not. Another possibility is that children tend to be more excited at events like birthday and Halloween parties where sugary foods are usually served . People may have confused proximity with correlation although the environment is probably more to blame than the food.

Vad är farligast - Lightläsk eller vanlig läsk?
En vanlig fråga som dyker när det gäller läskdrickande är om det är farligt med sötningsmedel. Det finns ju en allmän oro för tillsatser idag och frågan brukar gälla sötningsmedel men framför allt gäller det sötningsmedlet aspartam. Och om det är farligt är det farligare än att dricka vanlig läsk? Det är inte alls ovanligt att man träffar på personer som avstår från att dricka lightläsk då de tror att tillsatserna och sötningsmedlet är farligare än det socker som de får i sig från den vanliga läsken.

En annan vanlig fråga är hur dåligt det egentligen är att dricka läsk regelbundet. Hur stor påverkan kommer läsken att ha och påverkas kroppen även om man inte går upp i vikt? Det finns ett antal studier på djur och då främst råttor och möss där man sett en specifik negativ inverkan av sockersötad dryck där fruktosen i drycken verkar vara det som ställer till med den mest negativa effekten på hälsan (1, 2). I dessa djurstudier har man också sett att om man har en dryck som endast sötas med glukos så kommer effekten inte att vara lika negativ som en dryck med fruktos vilket ytterligare understryker fruktosens del i det hela. Korttidsstudier på människor har också visat att fruktosen i socker är det som har störst negativ inverkan på hälsan (17, 18).

There’s a huge hidden downside to standing desks that no one told me about - Quartz
It wasn’t fear of cancer, heart attacks, diabetes or even early death that did it. The reason I switched to a standing desk was, simply, to find a reprieve from pain. Since I graduated from college, back pain and its cruel confederates—neck, shoulder, and hip pain—have been unshakable facts of life. I’m not talking about the odd lumbar throbbing after a late night at the office; low-grade agony was pretty much a given, flaring into something more blinding a few times a month. Workday, weekend, vacation—it didn’t really matter, nor did the number of treadmill miles or chaturangas I’d banked that month.
Then in May, I read about how a standing desk helped allay a blogger’s chronic back woe. I was sold. I set my iMac on top of a small table on my home desk and put in a request for a standing desk at work. Vindication was almost instant. Within a week, my back pain started receding; a month on, and I’d almost forgotten about it. Aside from a weird hip glitch in August, the back pain is still mostly gone.
But in its place came something new. Fetching a dropped pen one day, I noticed bulbs of pinkish flesh ballooning out over my shoes, which, when removed, revealed swelling wider in girth than my feet and lower legs. Cankles, in other words.

Caffeine is actually slowing you down - Quartz
Here’s why you’ll want to: caffeine has a six-hour half-life, which means it takes a full 24 hours to work its way out of your system. Have a cup of joe at 8am, and you’ll still have 25% of the caffeine in your body at 8pm. Anything you drink after noon will still be at 50% strength at bedtime. Any caffeine in your bloodstream—with the negative effects increasing with the dose—makes it harder to fall asleep.
When you do finally fall asleep, the worst is yet to come. Caffeine disrupts the quality of your sleep by reducing rapid eye movement (REM) sleep, the deep sleep when your body recuperates and processes emotions. When caffeine disrupts your sleep, you wake up the next day with an emotional handicap. You’re naturally going to be inclined to grab a cup of coffee or an energy drink to try to make yourself feel better. The caffeine produces surges of adrenaline, which further your emotional handicap. Caffeine and lack of sleep leave you feeling tired in the afternoon, so you drink more caffeine, which leaves even more of it in your bloodstream at bedtime. Caffeine very quickly creates a vicious cycle.

Scientists agree: Coffee naps are better than coffee or naps alone - Vox
If you're feeling sleepy and want to wake yourself up — and have 20 minutes or so to spare before you need to be fully alert — there's something you should try. It's more effective than drinking a cup of coffee or taking a quick nap.

It's drinking a cup of coffee and then taking a quick nap. This is called a coffee nap.

It might sound crazy: conventional wisdom is that caffeine interferes with sleep. But if you caffeinate immediately before napping and sleep for 20 minutes or less, you can exploit a quirk in the way both sleep and caffeine affect your brain to maximize alertness. Here's the science behind the idea.

Rob Delaney — On Depression & Getting Help
I deal with suicidal, unipolar depression and I take medication daily to treat it. Over the past seven years, I’ve had two episodes that were severe and during which I thought almost exclusively of suicide. I did not eat much and lost weight during these episodes. I couldn’t sleep at all, didn’t even think about sex, and had constant diarrhea. The first thing I did each morning was vomit. My mind played one thought over and over, which was “Kill yourself.” It was also accompanied by a constant, thrumming pain that I felt through my whole body. I describe the physical symptoms because it helps to understand that real depression isn’t just a “mood.” These two episodes were the most difficult experiences of my life, by a wide margin, and I did not know if I would make it through them. To illustrate how horrible it was, being in jail in a wheelchair with four broken limbs after the car accident that prompted me to get sober eight years ago was much, much easier and less painful. That isn’t an exxageration and I hope it helps people understand clinical depression better; I’m saying that I would rather be in jail in a wheelchair with a body that doesn’t work than experience a severe episode of depression.

Hyperbole and a Half: Depression Part Two
The beginning of my depression had been nothing but feelings, so the emotional deadening that followed was a welcome relief.  I had always wanted to not give a fuck about anything. I viewed feelings as a weakness — annoying obstacles on my quest for total power over myself. And I finally didn't have to feel them anymore.

But my experiences slowly flattened and blended together until it became obvious that there's a huge difference between not giving a fuck and not being able to give a fuck. Cognitively, you might know that different things are happening to you, but they don't feel very different.

Suicide and society: Where does responsibility for preventing suicide lie? | Valerie Aurora
Every time a well-known person commits suicide, I brace myself for a torrent of well-meaning but patronizing advice to suicidal people on various social networks and blogs as the friends of the victim try to find something – anything – positive to do in a situation that is by definition past all help. Most often this takes the form of lecturing people to talk to their friends or family if they are feeling depressed or suicidal, mixed with a little “If only they’d known how much we liked them, they would have stayed alive!” That sentiment in particular is infuriating to many people who have been suicidal, since they are often aware that people love or depend on them and feel more guilt for knowing they are letting them down. It also trivializes suicidal feelings – oh, cheer up, people love you, okay!

For many depressed people, telling them “You should talk to a friend!” is worse than useless advice and may actually make people more suicidal. I argue that we, as as society, should take more responsibility for making people’s lives bearable, and focus on supporting more concrete ways to prevent suicide, like helping people contact professional help, supporting research and treatment of depression, and fighting for social justice.

Gary Taubes and the Cause of Obesity « Science-Based Medicine
The only grain of truth is that a low-carb diet may result in decreased hunger pangs so that total calorie intake drops. The laws of physics tell us that if you ate 7000 calories of protein and fat during a period of time when you only expended 3500 calories, you would gain a pound, even if you ate no carbohydrates at all. There is no getting around the physics. If you expend more calories than you ingest, you will lose weight. No diet has ever been shown to produce weight loss without a reduction in calories. The problem is that reducing calorie intake is fiendishly hard to accomplish for many reasons, both physiological and psychological. No one has ever denied that.

An Apple a Day, and Other Myths -
SAN DIEGO — A trip to almost any bookstore or a cruise around the Internet might leave the impression that avoiding cancer is mostly a matter of watching what you eat. One source after another promotes the protective powers of “superfoods,” rich in antioxidants and other phytochemicals, or advises readers to emulate the diets of Chinese peasants or Paleolithic cave dwellers.

But there is a yawning divide between this nutritional folklore and science. During the last two decades the connection between the foods we eat and the cellular anarchy called cancer has been unraveling string by string.

This month at the annual meeting of the American Association for Cancer Research, a mammoth event that drew more than 18,500 researchers and other professionals here, the latest results about diet and cancer were relegated to a single poster session and a few scattered presentations. There were new hints that coffee may lower the risk of some cancers and more about the possible benefits of vitamin D. Beyond that there wasn’t much to say.

Here are a few of the things that can make you hungry: seeing, smelling, reading, or even thinking about food. Hearing music that reminds you of a good meal. Walking by a place where you once ate something good. Even after you’ve just had a hearty lunch, imagining something delicious can make you salivate. Being genuinely hungry, on the other hand—in the sense of physiologically needing food—matters little. It’s enough to walk by a doughnut shop to start wanting a doughnut. Studies show that rats that have eaten a lot are just as eager to eat chocolate cereal as hungry rats are to eat laboratory chow. Humans don’t seem all that different. More often than not, we eat because we want to eat—not because we need to. Recent studies show that our physical level of hunger, in fact, does not correlate strongly with how much hunger we say that we feel or how much food we go on to consume.

Farewell to gluten free: Why we are so easily fooled by pseudoscience and marketing gimmicks when it comes to food | National Post
As a shortcut to health for the busy modern eater who does not have celiac disease, the rise of gluten free was “a function of people wanting simple solutions to complex problems. That’s just human nature. It’s not laziness,” said Dr. Freedhoff. “It’s fitting into the desire for ease: ease of thought and ease of implementation.”

As an eliminationist strategy, “gluten free” is the flip side of the nutrient fetish, in which substances are added, rather than subtracted, on much the same grounds, notably Omega 3s, polyphenols, amino acids, electrolytes and amino acids.

The problem is that, as Dr. Freedhoff has found, when you try to tell people they are fooling themselves by, for example, buying bread with “vegetables” in it (as per a current marketing campaign), or that Omega 3s don’t make their eggs any healthier, they react as if a foundational belief has been threatened, not just a dietary preference.

Selling a Poison by the Barrel: Liquid Nicotine for E-Cigarettes -
A dangerous new form of a powerful stimulant is hitting markets nationwide, for sale by the vial, the gallon and even the barrel.

The drug is nicotine, in its potent, liquid form — extracted from tobacco and tinctured with a cocktail of flavorings, colorings and assorted chemicals to feed the fast-growing electronic cigarette industry.

These “e-liquids,” the key ingredients in e-cigarettes, are powerful neurotoxins. Tiny amounts, whether ingested or absorbed through the skin, can cause vomiting and seizures and even be lethal. A teaspoon of even highly diluted e-liquid can kill a small child.

But, like e-cigarettes, e-liquids are not regulated by federal authorities. They are mixed on factory floors and in the back rooms of shops, and sold legally in stores and online in small bottles that are kept casually around the house for regular refilling of e-cigarettes.

News is bad for you – and giving up reading it will make you happier | Media | The Guardian
In the past few decades, the fortunate among us have recognised the hazards of living with an overabundance of food (obesity, diabetes) and have started to change our diets. But most of us do not yet understand that news is to the mind what sugar is to the body. News is easy to digest. The media feeds us small bites of trivial matter, tidbits that don't really concern our lives and don't require thinking. That's why we experience almost no saturation. Unlike reading books and long magazine articles (which require thinking), we can swallow limitless quantities of news flashes, which are bright-coloured candies for the mind. Today, we have reached the same point in relation to information that we faced 20 years ago in regard to food. We are beginning to recognise how toxic news can be.
