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."

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.”"
