Ренегаты из диетологов пытаются открыть народу правду.

Three specialists argued that eating "real food", taking exercise and reducing stress are better ways to stave off heart disease than cutting out dietary saturated fat. Writing in a respected journal, they maintained that inflammation is the chief threat to arteries and there is little evidence linking saturated fat consumption with heart disease, diabetes and premature death. But the editorial, published in the British Journal of Sports Medicine, attracted scathing criticism for being "simplistic", "muddled" and "misleading".

However the authors found an ally in Dr Mary Hannon-Fletcher, head of the school of health sciences at the University of Ulster, who described the editorial as "the best dietary and exercise advice I have read in recent years". She added: "Walking 22 minutes a day and eating real food. This is an excellent public health message; the modern idea of a healthy diet where we eat low-fat and low-calorie foods is simply not a healthy option."

After adjustments for age, sex, education (for analysis of dementia), caloric intake, diet quality, physical activity, and smoking, higher recent and higher cumulative intake of artificially sweetened soft drinks were associated with an increased risk of ischemic stroke, all-cause dementia, and Alzheimer’s disease dementia.

Хорошие новости! There's good news for kids who haven't received all their HPV vaccines yet - they only need two doses of the vaccine instead of three, federal government advisers said Wednesday.

А вот ещё: Skip that annual physical exam: Evidence increasingly suggests it’s useless.

Думаю, эти научные открытия происходят в первую очередь благодаря Обамакеру.

Хорошая новость: машина, выдуманная смертельность которой прославила Ральфа Нейдера и помогла высосать из пальца необходимость регулирования автопромышленности, растёт в цене.

The Corvair is known for being fun to drive, thanks to its rear-placed and air-cooled flat-six engine. It earned the nickname "the Poor Man's Porsche" for its driving style.



According to Hagerty, the average price of a mid-level Corvair in satisfactory and drivable condition today is $6,600, with later models of the 500 line averaging closer to $9,700. Examples in mint condition can run to $20,000 or even, very rarely, $30,000. Values have leveled a bit in recent years, but Klinger doesn’t expect a plunge. The best idea is to buy one, work on it, have fun with it for a year or two, then sell it for as much or a little more than you paid for it. Despite a slight dip in value for earlier models, Corvairs made from 1965 to 1969 have risen nearly 12 percent in value, on average, since 2011. Corvairs from 1968 are up 23.78 percent over the same period, with models from 1966 and 1967 up in value nearly as much.

AP -- The federal government has recommended flossing since 1979, first in a surgeon general's report and later in the Dietary Guidelines for Americans issued every five years. The guidelines must be based on scientific evidence, under the law.

Last year, the Associated Press asked the departments of Health and Human Services and Agriculture for their evidence, and followed up with written requests under the Freedom of Information Act.

When the federal government issued its latest dietary guidelines this year, the flossing recommendation had been removed, without notice. In a letter to the AP, the government acknowledged the effectiveness of flossing had never been researched, as required.

Как обычно: Good outcomes when families choose antibiotics to treat appendicitis.

Между тем, ученые медики обсуждают, при каких условиях допустимо предоставить пациенту выбор между различными стратегиями лечения. Предварительная, не всеми пока поддерживаемая идея такая: demonstrating that different treatment options have equivalent outcomes helps to determine whether offering a choice is safe.

In a new study in the journal Obesity Science & Practice, Cornell professors analyzed the food intake of about 6,000 people, according to MarketWatch. The study found that consuming more fast food, candy and soda was not correlated with higher body mass indexes—“While a diet of chocolate bars and cheeseburgers washed down with a Coke is inadvisable from a nutritional standpoint, these foods are not likely to be a leading cause of obesity.”

Из этой заметки, дорогие друзья, мы с вами узнали, что существует журнал под названием Obesity Science and Practice. Obesity Science & Practice, an official journal of World Obesity (WO) and The Obesity Society (TOS), is a peer-reviewed, online-only, open access journal of high quality research related to all aspects of obesity and its comorbidities.

NPR: How important is preschool?

A new answer comes in the form of a study — out of Vanderbilt University in Nashville, Tenn. — that is as clear as it is controversial.

The focus of the research is Tennessee's Voluntary Pre-K program. It's state-funded preschool on a grand scale, serving 18,000 of the state's poorest children, costing about $86 million a year and built on one big assumption:

That the answer to that earlier question is, "Very."

And Vanderbilt researcher Dale Farran says that at first glance, her team's results showed a big positive impact.

"The children who'd had the Voluntary Pre-K program were much better prepared for kindergarten by all of our achievement measures — significantly so," Farran says.

The Vanderbilt researchers followed nearly 800 children through the program along with a smaller control group of kids, most of whom did not attend pre-K.

Here's where the controversy starts: By the end of kindergarten, Farran noticed something odd in the data: "The children who had not had pre-K caught up," she says. Keep in mind, all of the kids in the study are low-income, which makes the team's next headline even stranger.

"By the end of second grade," Farran says, "the children who'd had state pre-K were underperforming the control children. And that continued into third grade."

Ученые педиатры установили, что shaken baby syndrome тоже не существует. Почему обвиненные в убийствах родители до сих пор в тюрьмах, ученые юристы пока не знают.
For decades, the pathologist, who works at the John Radcliffe Hospital, Oxford, appeared as a prosecution witness against parents accused of killing their children.
She argued that a combination of three brain injuries — swelling of the brain, bleeding between the skull and brain and bleeding in the retina — was sufficient to determine that the death resulted from a child being violently shaken.
But more than a decade ago, amid the emergence of research disputing the mainstream theory, Dr Squier had a change of heart, becoming convinced that such symptoms were not conclusive.

U.S. dietary guidelines have long recommended that people steer clear of whole milk, and for decades, Americans have obeyed. Whole milk sales shrunk. It was banned from school lunch programs. Purchases of low-fat dairy climbed. “Replace whole milk and full-fat milk products with fat-free or low-fat choices,” says the Dietary Guidelines for Americans, the federal government's influential advice book, citing the role of dairy fat in heart disease.

In fact, research published in recent years indicates that the opposite might be true: millions might have been better off had they stuck with whole milk.

American Educational Research Association -- Are American schools making inequality worse? According to a study published today in Educational Researcher, the answer appears to be yes. "In the United States, public school curricular and tracking policies are contributing to the growing performance gap between poor and rich students," said Schmidt. "Because of differences in content exposure for low- and high-income students in this country, the rich are getting richer and the poor are getting poorer. The belief that schools are the great equalizer, helping students overcome the inequalities of poverty, is a myth."

NYT -- More recently, a study of radon by a Johns Hopkins scientist suggested that people living with higher concentrations of the radioactive gas had correspondingly lower rates of lung cancer. If so, then homeowners investing in radon mitigation to meet federal safety standards may be slightly increasing their cancer risk.

CNSNews.com --A British professor's new model of solar cycles predicts that the Earth could be heading toward a "mini ice age" that would create conditions not seen since 1645 during the "Maunder minimum" - when London’s Thames River froze over. Solar activity may fall by as much as 60 percent during the 2030s, according to Mathematics Professor Valentina Zharkova of Northumbria University in England.
