<p>The Atkins low-carb, high-fat diet is supposed to be simple, but it's raising complex medical and nutrition questions. Now two new studies show that those who follow the diet can lose significant amounts of weight, but other research is raising concerns about the safety of the program, linking it to an increased risk of kidney stones and bone loss.</p>

<p>With courage and care Dr. Ravnskov exposes the lack of experimental evidence for the diet-heart theory, which claims that eating less fat and cholesterol will prevent atheroslcerosis (hardening of the arteries) and myocardial infarctions (heart attacks). By examining original peer-reviewed literature, the author finds no support for the diet-heart theory. He gives examples of scientific fraud among efforts to support the theory, including the deliberate selective omission of data points, and the deliberate assignment of subjects in a clinical trial to treatment or to control groups by physicians with the subject's medical records in hand. He shows how the abstract or conclusions of a number of papers are at odds with the actual data in the papers. He demonstrates how the use of one statistical method in preference to another can give a false impression that there is an effect, where there is, in fact, none. He shows how the reporting of differences in fatality rates by per cent reduction (say, a 50% reduction in relative risk) is actually misleading when the actual death rates are quite small in both the treatment and control groups of subjects in diet or drug studies. For example, a treatment that changes the absolute survival rate over a multi-year period from 99.0% to 99.5% represents a 50% reduction in relative risk, from 1% to 0.5% absolute. This is often described in papers as a 50% reduction in death rate. However, when the difference is barely significant statistically, as was often the case, Ravnskov points out that there is no real reason to recommend adoption of the treatment, especially if there are serious side-effects.</p>

... A new study from the Harvard School of Public Health suggests that the heart risk long associated with red meat comes mostly from processed varieties such as bacon, sausage, hot dogs and cold cuts—and not from steak, hamburgers and other non-processed cuts. The finding is surprising because both types of red meat are high in saturated fat, a substance believed to be partly responsible for the increased risk of heart disease. But the new study raises the possibility that when it comes to meat, at least, the real bad actor may be salt. Processed meats generally have about four...

Tens of thousands of Vietnam veterans with ischemic heart disease, Parkinson’s disease or B cell leukemia should file claims now with the Department of Veterans Affairs for disability compensation, and not wait until VA publishes a regulation officially linking these diseases to wartime service. Advocacy groups are urging the swift filing of claims because veterans eventually found eligible for disability pay for these diseases will be able to receive compensation back to the date their claims were filed. Those who wait for a regulation to add these ailments to VA’s list of diseases presumed caused by exposure to Agent Orange...

A study of 130,054 adults found that people who drank four cups or more of coffee daily had an 18 percent lower risk of being hospitalized for irregular heartbeats and other heart- rhythm conditions than noncoffee drinkers, researchers at Kaiser Permanente, an Oakland, California-based health system, said today. The risk of hospitalization was 7 percent lower for people who drank one to three cups of coffee daily... Cardiac rhythm disorders are problems in the heart’s electrical systems that cause it to beat too fast, too slow or irregularly. Atrial fibrillation, a rapid, irregular heart beat that is the most common...

Those curves are making cardiologists smile. A new study out of Oxford University in England found women with "pear-shaped" figures -- ample extra padding around the hips, buttocks and thighs -- are actually at a lower risk for heart and metabolic diseases. "It is shape that matters and where the fat gathers," said Oxford's Dr. Konstantinos Manolopoulos, explaining that fat stored on the hips and in the rear absorb harmful fatty acids and further prevent arteries from clogging. "Fat around the hips and thighs is good for you, but around the tummy is bad," he told BBC News, noting that...

A major medical paper on primary heart disease prevention admitted that cardiovascular disease risk factors have proven useless for predicting heart disease among our population and that reducing risks factors doesn’t translate into reduced clinical disease or fewer premature deaths. But the solutions to this conundrum were the most unbelievable examples of ad-hoc reasoning.

As Montana bars dealt with their first smoke-free weekend since the state’s indoor smoking ban went into effect, ingenuity ruled. In Missoula, according to a great piece by Michael Moore in the Missoulian, the Rhino Bar gave smokers their very own place to light up: a Butt Hutt, created by Dave Golden of Well Done Welding and Jim Bell, a general contractor. Moore describes the hut as a 4-by-8-foot “metal smoking dugout” in the alley behind the Rhino in Missoula. The no-smoking laws spark the type of debate that never seems to get extinguished. Pro-smokers argue that the bans hurt...

A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin. "It's likely that more than one-third of older adults...

Leg size may be a more accurate indicator of risks than the waistline. We know having a large waistline is unhealthy. But larger thighs, it appears, may protect against heart disease and premature death. A study published on BMJ.com, the website of the British Medical Journal, found that men and women whose thighs are less than 23.6 inches have a higher risk of premature death and heart disease compared with those with thighs exceeding that size. Having thighs that are even bigger, however, confers no added benefit. The study is the first to suggest that thigh size matters. The measurement...

PARIS (AFP) – Heart attack survivors who eat chocolate two or more times per week cut their risk of dying from heart disease about three fold compared to those who never touch the stuff, scientists have reported. Smaller quantities confer less protection, but are still better than none, according to the study, which appears in the September issue of the Journal of Internal Medicine. Earlier research had established a strong link between cocoa-based confections and lowered blood pressure or improvement in blood flow. It had also shown that chocolate cuts the rate of heart-related mortality in healthy older men, along...

Enlarge ImageEvolving evidence. In a massive study, C-reactive protein didn’t boost the risk of heart attacks.Credit: Wikipedia A new study may be the last word in a controversy that's plagued cardiovascular disease research for years: whether a marker of inflammation known as C-reactive protein (CRP) drives heart attacks and strokes. In a survey of more than 128,000 people, researchers have found that genes that raise CRP levels don't make cardiovascular disease more likely. Although the study arrives at the same conclusion as earlier work, its massive size makes it statistically the most powerful test yet of this question and...

TAMPA, Florida (Reuters) - Billy Mays, well known for pitching a variety of products in U.S. television commercials, had heart disease but did not appear to have suffered head trauma in a rough airplane landing prior to dying in his sleep on Sunday, a medical examiner in Florida said on Monday. The bearded, black-haired Mays, 50, who gained fame as an enthusiastic TV "pitchman" advertising an array of commercial products, was found dead by his wife at their home in Tampa, Florida. On Saturday, Mays was among the passengers aboard a U.S. Airways flight from Philadelphia that landed roughly at...

Peanut butter sandwiches, favoured by cartoon character Charlie Brown, could be the secret to beating heart disease, according to new research. A study in the US reveals snacking on peanuts or peanut butter at least five days a week can nearly halve the risk of a heart attack. A team of experts at Harvard Medical School in Boston came up with the findings after studying the eating habits of thousands of women with type two diabetes. The condition dramatically increases the risk of heart attacks and strokes. Poor diet and lifestyle has led to a surge in the numbers affected...

Obesity may protect against death from heart disease, scientists from Louisiana claim. Researchers found that obese heart patients respond better to strokes and heart attacks compared to normal or underweight patients. Although obesity is a leading cause of heart disease, paradoxically scientists say fat and even high cholesterol may have protective benefits. But researchers say losing weight is still best because obesity triggers more heart attacks and strokes. Cardiologist Carl J. Lavie, of the Ochsner Medical Center in New Orleans, Louisiana, said: " Overweight heart patients do better than thin patients, but overweight patients who lose weight do best of...

It's been a dream for a decade: a single daily pill combining aspirin, cholesterol medicine and blood pressure drugs — everything people need to prevent heart attacks and strokes in a cheap, generic form. Skeptics said five medicines rolled into a single pill would mean five times more side effects. Some people would get drugs they don't need, while others would get too little. One-size-fits-all would turn out to fit very few, they warned. Now the first big test of the "polypill" has proved them wrong. The experimental combo pill was as effective as nearly all of its components taken...

CBNNews.com - Men should start taking a daily aspirin at age 45 to lower the risk of heart attack by 20 percent, according to recent U.S. Preventive Services findings. Doctors add that women should start a daily aspirin regimine at age 55 to protect against strokes. However, some medical experts have concerns.

Did Grandma seem forgetful at the holiday parties last month? It could be time to put her on a diet. Sharply reducing calories improves memory in older adults, according to one of the first studies of dietary restriction and cognitive function in humans. Research on the benefits of an extremely low-calorie diet stretches back to the 1930s, when scientists found that rats lived up to twice as long when they nibbled less than control animals. Since then, some studies with rodents and nonhuman primates have shown that this spare diet, known as calorie restriction, improves some markers of diabetes and...
