Sedentary lifestyles of adolescents jeopardizes their health

More than 80% of young people between ages 11 and 17 are not exercising enough, according to a World Health Organization-led study based on data from 1.6 million people in 146 countries.

Dr Mark Tremblay, of the Children’s Hospital of Eastern Ontario Research Institute in Canada, said in the Journal that physical inactivity is the fourth leading risk factor for premature death worldwide.

“The electronic revolution has fundamentally transformed people’s movement patterns by changing where and how they live, learn, work, play and travel, progressively isolating them indoors,” he said.

People sleep less, sit more, walk less frequently, drive more regularly and do less physical activity than they used to.

“They are increasingly moving from one country to another, from rural to urban areas, from outdoors to indoors, from standing to sitting, from walking to driving, and from active play to digital play.” These changes, he said, could have profound effects on human health.

In the United States, despite a national plan promoting physical exercise since 2010, obesity rates have risen among adolescents, especially those who eat food high in salt and sugar, studies show.

The WHO study, published in The Lancet Child & Adolescent Health journal, said many sports in the United States seem designed to attract boys more than girls. The inactivity rate among American girls was 81%, compared to 64% for boys.

Riley said that as teenage activity levels stagnate, rates of weight gain and obesity are growing: “These two phenomenon are of concern. We need to do more if we want to halt the rise in obesity … and promote better rates of physical activity.”

That four in every five adolescents do not experience the enjoyment and social, physical and mental health benefits of regular physical activity is not by chance, but a consequence of political choices and societal design.

Even among smokers, people who eat more fiber and yogurt may be less likely to develop lung cancer

Lisa Rapaport »

Compared to people who never ate yogurt, those who consumed the most yogurt were 19% less likely to develop lung cancer, the analysis found.

People who had the most fiber in their diets, meanwhile, were 17% less likely to develop lung cancer than those who ate the least fiber.

And individuals with the highest fiber intake and highest yogurt consumption were 33% less likely than those with the lowest consumption of both to develop lung cancer, the study team reports in JAMA Oncology.

Apple is removing vaping and e-cigarette apps from the App Store

As deaths related to e-cigarettes increase, Apple is taking a stand.

Ina Fried, Mike Allen »

Apple in a statement to Axios: “We take great care to curate the App Store as a trusted place for customers, particularly youth, to download apps. We’re constantly evaluating apps, and consulting the latest evidence, to determine risks to users’ health and well-being.”

  • “Recently, experts ranging from the CDC to the American Heart Association have attributed a variety of lung injuries and fatalities to e-cigarette and vaping products, going so far as to call the spread of these devices a public health crisis and a youth epidemic.”
  • “We agree, and we’ve updated our App Store Review Guidelines to reflect that apps encouraging or facilitating the use of these products are not permitted. As of today, these apps are no longer available to download.”

Coconut oil is marketed as healthy, but it has more saturated fat than butter or lard

Katie Pedersen, Chelsea Gomez, Asha Tomlinson »

It’s regularly touted as a “superfood” or a “healthy fat” and is found in supermarkets and health food stores across the country.

But coconut oil is made up almost entirely of saturated fat. In a 14-gram tablespoon, about 13 grams — over 90 per cent — is saturated fat.

That’s nearly double the amount in the same volume of butter, 2.5 times as much as lard, and more than six times the saturated fat of olive oil.

A good night’s sleep can help reduce anxiety


Yasmin Anwar »

Researchers have found that the type of sleep most apt to calm and reset the anxious brain is deep sleep, also known as non-rapid eye movement (NREM) slow-wave sleep, a state in which neural oscillations become highly synchronized, and heart rates and blood pressure drop.

“We have identified a new function of deep sleep, one that decreases anxiety overnight by reorganizing connections in the brain,” said study senior author Matthew Walker, a UC Berkeley professor of neuroscience and psychology. “Deep sleep seems to be a natural anxiolytic (anxiety inhibitor), so long as we get it each and every night.”

The findings, published this month in the journal Nature Human Behaviour, provide one of the strongest neural links between sleep and anxiety to date. They also point to sleep as a natural, non-pharmaceutical remedy for anxiety disorders, which have been diagnosed in some 40 million American adults and are rising among children and teens.

Diets low in fruits and vegetables have been linked to depression

Brittany A. Roston, writing for SlashGear »

The latest research on the topic comes from the University of Toronto, which found that both men and women who eat low amounts of fruit and vegetables are more likely to suffer from depression. As well, the study found that men in particular were at a higher risk of depression if they ate high levels of fat or consumed low amounts of omega-3 fatty acids.

This isn’t the first study to find that eating more fruit and vegetables may lower depression risk, underscoring the persistent relationship between the two. Though the exact link between depression and these foods remains unclear, researchers speculate that the various beneficial compounds found in fruit and vegetables may play a role in protecting mental health.

As well, the researchers note that various nutrients — specifically, certain vitamins and minerals — found in vegetables and fruit are known to lower the plasma concentration of C-reactive protein, which is a biomarker for low levels of inflammation that has been linked to depression.


National Parks may save $6 trillion in mental health costs worldwide

Steve Casimiro, writing in Adventure Journal »

A new study shows that national parks worldwide are worth an estimated $6 trillion—with a “T”— in mental health benefits. A team from Australia’s Griffith University, comprised of ecologists, psychologists, and economists, looked at the psychological benefits of national park visits and compared them to the costs of poor mental health. They sampled 20,000 people in three groups, looking at improved cognition, sleep, stress relief, and reduced anxiety and depression. Overwhelmingly, parks made things better.

The researchers were able to attach an economic value on the mental health benefits of national parks, and open spaces in general, by factoring in how much countries spend on mental health treatment and care, while taking into account poor workplace productivity and antisocial behavior. They also examined the quality-adjusted life years of the three groups under study, an economic tool that experts use to measure the value of medical care by reducing a person’s pain, whether mental or physical.

Being kind could help you live longer

Columbia University doctor Kelli Harding has been examining the phenomenon in her recent book, The Rabbit Effect.

She says: “It helps the immune system, blood pressure, it helps people to live longer and better. It’s pretty amazing because there’s an ample supply and you can’t overdose on it. There’s a free supply. It’s right there.”

Memo doesn’t follow fitness trends, and he’s one of the fastest runners in the world

Memo believes in two things » 1) Hard work, and 2 Never giving up.

NY Times via YouTube »

In a cluttered world of boutique fitness studios and high-end gear, Guillermo Piñeda Morales reminds us that we don’t need much to be our best.

In the Video Op-Ed above, we trail Guillermo Piñeda Morales, a.k.a. Memo. He clocked a 2:28:42 at this year’s Boston Marathon, placing him in the top 10 marathon runners for his age group globally. That’s very fast.

The American fitness industry is worth $30 billion, but Memo’s not in on the trend. He won’t pop up in your Instagram #fitspo feed and you won’t get a glimpse of him at your gym. But if you’re at the New York City Marathon this Sunday — or if you have a resolution to run a marathon next year — Memo is likely to be whizzing past you.

What’s Memo’s trick? Well, you can find that in the video. But it’s far simpler and cheaper than anything else out there.
