How To tell Emergency Room Patients That They're Dying.
On television, the emergency room patients beat the odds. Their hearts get shocked back to life. Their organs get sewn up. They awaken to a handsome young physician's dazzling smile.
In real life, one in 500 ER patients—200,000 a year—dies under the bright lights of the emergency rooms. Another 500,000—3 percent—die during hospital stays following emergency treatment. Countless patients learn, from a doctor they have never seen before and may never see again, that they have fatal diseases. Others get treated, aggressively and repeatedly, for dangerous flare-ups in conditions like heart failure or emphysema without anyone having the time or the skills to explain that the chronic disease they have been living with is now the chronic disease that they are slowly dying from, a scenario Atul Gawande explored in his recent New Yorker piece on what doctors can do when they can no longer cure.

Health Checkup: Who Needs Organic Food?
Organic food comes with real health benefits and significant costs. TIME looks at both sides of the debate
From Time Magazine:
Looking for a quick way to feel lousy about yourself? Then forget the idea of a healthy diet and just eat what your body wants you to eat. Your body wants meat; your body wants fat; your body wants salt and sugar. Your body will put up with fruits and vegetables if it must, but only after all the meat, fat, salt and sugar are gone. And as for the question of where your food comes from — whether it's locally grown, sustainably raised, grass-fed, free range or pesticide-free? Your body doesn't give a hoot.

Why Do Heavy Drinkers Outlive Nondrinkers?
From Time Magazine:
One of the most contentious issues in the vast literature about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do. The standard Alcoholics Anonymous explanation for this finding is that many of those who show up as abstainers in such research are actually former hard-core drunks who had already incurred health problems associated with drinking.

Obesity: Food Kills, Flab Protects
From The New Scientist:
OBESITY kills, everyone knows that. But is it possible that we've been looking at the problem in the wrong way? It seems getting fatter may be part of your body's defence against the worst effects of unhealthy eating, rather than their direct cause.
This curious insight comes at the same time as several studies distancing obesity itself from a host of diseases it has long been blamed for, including heart disease and diabetes.

'Biological Clock' Could Be a Key to Better Health, Longer Life
From Science Daily:
Science Daily (Mar. 2, 2010) — If you aren't getting a good, consistent and regular night's sleep, a new study suggests it could reduce your ability to handle oxidative stress, cause impacts to your health, increase motor and neurological deterioration, speed aging and ultimately cut short your life.

When It Comes To Salt, No Rights Or Wrongs. Yet.
Suppose, as some experts advise, that the new national dietary guidelines due this spring will lower the recommended level of salt. Suppose further that public health officials in New York and Washington succeed in forcing food companies to use less salt. What would be the effect?

'The Biggest Loser' Has Big Problems, Health Experts Say

From Live Science:
NBC's "The Biggest Loser" is all about records. In the past seasons, the weight-loss reality show has repeatedly set new benchmarks for heaviest contestant (454, 476 and 526 pounds), fastest 100-pound weight loss (seven weeks), and most weight lost in one week (34 pounds).
The show, which takes obese Americans and pits them against each other in a battle to lose the most weight and win $250,000, thrives on extreme numbers. But physicians and nutritionists worry the show's focus on competitive weight loss is, at best, counterproductive and, at worst, dangerous.

Obesity In Kids: Three Lifestyle Changes That Help
From Time Magazine:
To curb the childhood-obesity epidemic, health experts have long urged parents to make healthy changes to their family's lifestyle — such as eating nutritiously, reducing TV time, exercising and getting a good night's sleep.
Individually, these behaviors have been linked to a lower risk of obesity in kids, but researchers at Ohio State University were interested in learning whether their effect might be cumulative — that is, whether families who adopted not just one but two or more of these behaviors could reduce their children's risk of obesity even further.

Botox May Deaden Not Just Nerves, But Emotions, Too
Sure, Botox can banish crows feet, smooth those wrinkles, and lift those frown lines, making the client look more youthful–and somewhat expressionless. But the treatment may have effects that are more than skin deep. A new study suggests that by paralyzing the frown muscles that ordinarily are engaged when we feel angry, Botox short-circuits the emotion itself [Newsweek].

Even Small Dietary Reductions In Salt Could Mean Fewer Heart Attacks, Strokes And Deaths
From Science Daily:
Science Daily (Jan. 21, 2010) — Reducing salt in the American diet by as little as one-half teaspoon (or three grams) per day could prevent nearly 100,000 heart attacks and 92,000 deaths each year, according to a new study. Such benefits are on par with the benefits from reductions in smoking and could save the United States about $24 billion in healthcare costs, the researchers add.

Ban Butter To Save Our Hearts, Says Doctor
is a very simple thing to do Photo: CORBIS
From The Telegraph:
Butter should be banned in a bid to save thousands from heart disease, a leading heart surgeon claims.
Dr Shyam Kolvekar said that he is "increasingly concerned" about the nation's eating habits as he is seeing patients as young as 30 in need of heart bypass surgery due to a diet "overloaded" with saturated fat.
According to a national diet survey, nine out of 10 of children, 88 per cent of men and 83 per cent of women in Britain eat too much saturated fat, consuming a fifth too much each day.

Study: Running Shoes Could Cause Joint Strain
From Live Science:
Running shoes, decked out with the latest cushioning, motion control and arch support technologies, may not be as beneficial to your feet and joints as you might think.
A new study finds that running shoes, at least the kind currently on the market, may actually put more of a strain on your joints than if you were to run barefoot or even to walk in high-heeled shoes, and the increased pressure could lead to knee, hip and ankle damage. The scientists don’t recommend ditching your high-tech sneaks, however, as going barefoot on man-made surfaces could also prove harmful,

Childhood Obesity Linked To Mutant Gene
From The Telegraph:
Childhood obesity could be caused by a genetic mutation, scientists at Cambridge University believe.
Findings show for the first time that the condition can be a genetic one, rather than the result of over feeding.
The study could have a major impact on the decision of social services to take obese children into care where they believe they are being abused.

Skin Cream Secrets Revealed

From Live Science:
If asked to describe how skin cream feels, you might use words like "smooth," "thick," or "greasy."
But for Ohio State University mechanical engineering professor Bharat Bhushan, these words aren't good enough. Using a special instrument, he has gleaned new understanding of how these creams interact with skin on the nanoscale, bringing a more quantitative measure to the smooth sensation.

Sound Body Equals Sound Mind, Study Finds
From Live Science:
A new study proves the old Roman saying, "A sound mind in a sound body" — the more fit one's heart is, the more one's brain seems to benefit, scientists now find.
Many earlier studies have linked physical exercise with brainpower in humans and animals, but most of the research in people focused on children or older adults. The few studies of young adulthood — when the brain changes rapidly, establishing many traits linked with intelligence — have yielded ambiguous data.

Attractiveness Based Partly on Skin Color
From Live Science:
When it comes to an attractive face, color can make all the difference, suggests a new study.
The research focused on facial skin color among Caucasians, finding a light, yellowish complexion looks the healthiest. The skin color could indicate a healthy diet of fruits and vegetables, whose pigments are known to change the skin's hue, researchers suggest.
(The researchers predict the results would hold for other ethnicities as well.)

Researchers Plan Ice Cream That's Good For You
In what might seem to defy the laws of comfort foods, researchers are setting out to concoct a healthy, yes healthy, ice cream.
If the food scientists are successful, ice cream would become another so-called functional food, alongside whole oat products and foods made with soy protein, which have scientifically established health benefits beyond basic nutrition. (The United States doesn't currently have a formal definition for functional foods.)

80 Min Exercise Per Week Prevents Visceral Weight Gain
From Future Pundit:
Fat around your internal organs is thought to be a much bigger risk factor for heart disease than fat near the surface of the skin. Well, if you go on a diet, exercise, get your weight down, and then eventually go off the diet continued exercise will prevent the resulting weight gain from happening where the risk factor is greatest.
BIRMINGHAM, Ala. - A study conducted by exercise physiologists in the University of Alabama at Birmingham (UAB) Department of Human Studies finds that as little as 80 minutes a week of aerobic or resistance training helps not only to prevent weight gain, but also to inhibit a regain of harmful visceral fat one year after weight loss.
