Lead author Dr Marcia Otto, from the University of Texas, Houston, said: 'Our findings not only support, but also significantly strengthen, the growing body of evidence which suggests that dairy fat, contrary to popular belief, does not increase risk of heart disease or overall mortality in older adults.
'In addition to not contributing to death, the results suggest that one fatty acid present in dairy may lower risk of death from cardiovascular disease, particularly from stroke.'
Dietary guidelines in the US and UK recommend people people opt for low or no-fat dairy, however, the researchers warn such options are often high in sugar, which can drive heart disease.

Experts admitted surprise at the findings because so many other studies have linked red meat to physical health risks. The team made the link after a study of 1000 Australian women. Professor Felice Jacka, who led the research by Deakin University, Victoria, said: "We had originally thought that red meat might not be good for mental health but it turns out that it actually may be quite important. "When we looked at women consuming less than the recommended amount of red meat in our study, we found that they were twice as likely to have a diagnosed depressive or anxiety disorder as those consuming the recommended amount. "Even when we took into account the overall healthiness of the women's diets, as well as other factors such as their socioeconomic status, physical activity levels, smoking, weight and age, the relationship between low red meat intake and mental health remained.
The artemisinin compound takes advantage of cancer cell's high iron levels. Artemisinin is highly toxic in the presence of iron, but harmless otherwise. Cancer cells need a lot of iron to maintain the rapid division necessary for tumor growth.
Since too much free-floating iron is toxic, when cells need iron they construct a special protein signal on their surfaces. The body's machinery then delivers iron, shielded with a protein package, to these signals proteins. The cell then swallows this bundle of iron and proteins.
Artemisinin alone is fairly effective at killing cancer cells. It kills approximately 100 cancer cells for every healthy cell, about ten times better than current chemotherapies. To improve those odds, the researchers added a small chemical tag to artemisinin that sticks to the "iron needed here" protein signal. The cancer cell, unaware of the toxic compound lurking on its surface, waits for the protein machinery to deliver iron molecules and engulfs everything -- iron, proteins and toxic compound.
Once inside the cell, the iron reacts with artemisinin to release poisonous molecules called free radicals. When enough of these free
radicals accumulate, the cell dies.
"The compound is like a little bomb-carrying monkey riding on the back of a Trojan horse," said Henry Lai, UW bioengineering professor and
co-author of the study.
The compound is so selective for cancer cells partly due to their rapid multiplication, which requires high amounts of iron, and partly because cancer cells are not as good as healthy cells at cleaning up free-floating iron.
"Cancer cells get sloppy at maintaining free iron, so they are more sensitive to artemisinin," Sasaki said.
Ramsden, of the National Institutes of Health, unearthed raw data from a 40-year-old study, which challenges the dogma that eating vegetable fats instead of animal fats is good for the heart. The study, the largest gold-standard experiment testing that idea, found the opposite, Ramsden and his colleagues reported on Tuesday in BMJ (formerly the British Medical Journal).
Although the study is more than just another entry in the long-running nutrition wars—it is more rigorous than the vast majority of research on the topic—Ramsden makes no claims that it settles the question. Instead, he said, his discovery and analysis of long-lost data underline how the failure to publish the results of clinical trials can undermine truth.
...
The coleader of the project was Dr. Ancel Keys, author of the Seven Countries Study, Time cover subject, and the most prominent advocate of replacing saturated fat with vegetable fat. “The idea that there might be something adverse about lowering cholesterol [via vegetable oils] was really antithetical to the dogma of the day,” Bob Frantz said.
His father, he said, “was always committed to discovering the truth. He would be pleased this is finally coming out.”

It is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.
Don’t look now, but maybe a scientific consensus exists concerning global warming after all. Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis, according to a survey reported in the peer-reviewed Organization Studies. By contrast, a strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem.
The survey results show geoscientists (also known as earth scientists) and engineers hold similar views as meteorologists. Two recent surveys of meteorologists (summarized here and here) revealed similar skepticism of alarmist global warming claims.
According to the newly published survey of geoscientists and engineers, merely 36 percent of respondents fit the “Comply with Kyoto” model. The scientists in this group “express the strong belief that climate change is happening, that it is not a normal cycle of nature, and humans are the main or central cause.”
Results
At baseline, 13.1% of participants reported daily consumption (usual amount 0.76 egg/day) and 9.1% reported never or very rare consumption (usual amount 0.29 egg/day). Compared with non-consumers, daily egg consumption was associated with lower risk of CVD (HR 0.89, 95% CI 0.87 to 0.92). Corresponding multivariate-adjusted HRs (95% CI) for IHD, MCE, haemorrhagic stroke and ischaemic stroke were 0.88 (0.84 to 0.93), 0.86 (0.76 to 0.97), 0.74 (0.67 to 0.82) and 0.90 (0.85 to 0.95), respectively. There were significant dose-response relationships of egg consumption with morbidity of all CVD endpoints (P for linear trend < 0.05). Daily consumers also had an 18% lower risk of CVD death and a 28% lower risk of haemorrhagic stroke death compared to non-consumers.

An extreme, all animal-based diet is gaining followers in search of heightened productivity, mental clarity, and a boosted libido. But experts express doubts
Instagram: shawnbaker1967At 51 years of age I am well aware of the tremendous evidence that demonstrates maintaining as much lean muscle mass as possible is necessary to mitigate the risks of cardiovascular disease and promotes excellent metabolic health-I remain incredibly insulin sensitive with a fasting insulin of just 2.6 and maintain extremely low levels of inflammation with a hsCRPof on 0.6 and also have very low triglycerides levels of only 54- also my VO2max is also among the best in the world for my age based on my rowing capacity- it is the entire system and its overall function that best indicate health!
A new documentary by controversial celebrity chef Pete Evans which claims the paleo diet can treat chronic disease has been slammed by Australia's top doctors.
The film, The Magic Pill, claims people suffering from illnesses such as diabetes, cancer and autism can reduce their symptoms and reliance on prescription drugs by adopting the diet for just five weeks. Australian Medical Association president Michael Gannon has compared the documentary to controversial anti-vaccination film, Vaxxed, and said the two were competing 'in the awards for the films least likely to contribute to public health'. 'Elements of the discussion are just plain hurtful, harmful and mean,' Dr Gannon told The Daily Telegraph.
The AMA's outburst came after Evans stood by his outspoken views on the paleo diet during an interview on Channel Seven's Sunday Night program.
'This way of eating reverses Type 2 diabetes. And guess how quickly it takes? Six to eight weeks. Maybe three months,' he said.
