Calorie Counters Have It Right, Diet Study Says

Calorie Counters Have It Right, Diet Study Says - WSJ.com:

"You aren't what you eat. You're how much.

That's the message from a two-year National Institutes of Health-funded study that assigned 811 overweight people to one of four reduced-calorie diets and found that all trimmed pounds just the same. It didn't matter what foods participants ate, but rather how many calories they consumed.

An intense debate has long raged over which dieting regimen is best. Low carb? High protein? Low fat? But the federal study, one of the longest of its kind, "really goes against the idea that certain foods are the key to weight loss," says Frank Sacks, principal investigator and a professor of cardiovascular-disease prevention at Harvard School of Public Health. "This is a pretty positive message. It gives people a lot of choices to find a diet they can stick with.""

Watching a lot of TV during adolescence can change a normal brain to a depressive one

Health scare of the week: Does TV damage teen brains? - Subscriber Only - THE WEEK:

"Watching a lot of TV during adolescence, an alarming new study has found, can change a normal brain to a depressive one. The study, which tracked more than 4,000 adolescents as they grew up, found that for every extra hour a teen spends watching TV or playing videogames on an average day, he or she is 8 percent more likely to develop depression as an adult. Study author Dr. Brian Primack says that teens’ experiences help shape their developing brains, and that being parked in front of a screen often replaces positive social, academic, and athletic activities that give kids a sense of mastery and self-respect. Instead, he tells the Los Angeles Times, TV teaches kids to be passive, and to judge themselves against fictional characters whose looks and accomplishments seem out of reach."

Vitamin Pills - A False Hope?

Well - Vitamin Pills - A False Hope? - NYTimes.com:

"Ever since the Nobel Prize-winning biochemist Linus Pauling first promoted “megadoses” of essential nutrients 40 years ago, Americans have been devoted to their vitamins. Today about half of all adults use some form of dietary supplement, at a cost of $23 billion a year.

But are vitamins worth it? In the past few years, several high-quality studies have failed to show that extra vitamins, at least in pill form, help prevent chronic disease or prolong life.

The latest news came last week after researchers in the Women’s Health Initiative study tracked eight years of multivitamin use among more than 161,000 older women. Despite earlier findings suggesting that multivitamins might lower the risk for heart disease and certain cancers, the study, published in The Archives of Internal Medicine, found no such benefit...

“I’m puzzled why the public in general ignores the results of well-done trials,” said Dr. Eric Klein, national study coordinator for the prostate cancer trial and chairman of the Cleveland Clinic’s Glickman Urological and Kidney Institute. “The public’s belief in the benefits of vitamins and nutrients is not supported by the available scientific data.”"

Babies Know - A Little Dirt Is Good for You

Personal Health - Babies Know - A Little Dirt Is Good for You - NYTimes.com:

"In studies of what is called the hygiene hypothesis, researchers are concluding that organisms like the millions of bacteria, viruses and especially worms that enter the body along with “dirt” spur the development of a healthy immune system. Several continuing studies suggest that worms may help to redirect an immune system that has gone awry and resulted in autoimmune disorders, allergies and asthma.

These studies, along with epidemiological observations, seem to explain why immune system disorders like multiple sclerosis, Type 1 diabetes, inflammatory bowel disease, asthma and allergies have risen significantly in the United States and other developed countries.

Training the Immune System

“What a child is doing when he puts things in his mouth is allowing his immune response to explore his environment,” Mary Ruebush, a microbiology and immunology instructor, wrote in her new book, “Why Dirt Is Good” (Kaplan). “Not only does this allow for ‘practice’ of immune responses, which will be necessary for protection, but it also plays a critical role in teaching the immature immune response what is best ignored.”

One leading researcher, Dr. Joel V. Weinstock, the director of gastroenterology and hepatology at Tufts Medical Center in Boston, said in an interview that the immune system at birth “is like an unprogrammed computer. It needs instruction.”

He said that public health measures like cleaning up contaminated water and food have saved the lives of countless children, but they “also eliminated exposure to many organisms that are probably good for us.”

“Children raised in an ultraclean environment,” he added, “are not being exposed to organisms that help them develop appropriate immune regulatory circuits.”"

The simple choices that we make in our lifestyle can be as powerful as drugs and surgery

"...if we want to make affordable health care available to the 45 million Americans who do not have health insurance, then we need to address the fundamental causes of health and illness, and provide incentives for healthy ways of living rather than reimbursing only drugs and surgery.

Heart disease, diabetes, prostate cancer, breast cancer and obesity account for 75% of health-care costs, and yet these are largely preventable and even reversible by changing diet and lifestyle....

The latest scientific studies show that our bodies have a remarkable capacity to begin healing, and much more quickly than we had once realized, if we address the lifestyle factors that often cause these chronic diseases. These studies show that integrative medicine can make a powerful difference in our health and well-being, how quickly these changes may occur, and how dynamic these mechanisms can be.

Many people tend to think of breakthroughs in medicine as a new drug, laser or high-tech surgical procedure. They often have a hard time believing that the simple choices that we make in our lifestyle -- what we eat, how we respond to stress, whether or not we smoke cigarettes, how much exercise we get, and the quality of our relationships and social support -- can be as powerful as drugs and surgery. But they often are. And in many instances, they're even more powerful....

Our "health-care system" is primarily a disease-care system. Last year, $2.1 trillion was spent in the U.S. on medical care, or 16.5% of the gross national product. Of these trillions, 95 cents of every dollar was spent to treat disease after it had already occurred. At least 75% of these costs were spent on treating chronic diseases, such as heart disease and diabetes, that are preventable or even reversible....

The disease that accounts for more premature deaths and costs Americans more than any other illness is almost completely preventable simply by changing diet and lifestyle. And the same lifestyle changes that can prevent or even reverse heart disease also help prevent or reverse many other chronic diseases as well....

It's time to move past the debate of alternative medicine versus traditional medicine, and to focus on what works, what doesn't, for whom, and under which circumstances...."
