1 egg yolk worse than a KFC Double Down when it comes to cholesterol

Doctors warn against dietary cholesterol for patients at risk of vascular disease

2010-11-02

(Press-News.org) London, ON - Three leading physicians have published a review in the Canadian Journal of Cardiology warning about the danger of dietary cholesterol for those at risk of a heart attack or stroke. And they say one of the worst offenders is the egg yolk which, depending on size, can contain 215 to 275 mg of cholesterol. The Double Down from Kentucky Fried Chicken contains 150 mg of cholesterol. Patients at risk of cardiovascular disease are advised to limit their total dietary cholesterol to less than 200 mg per day.

The review of studies was authored by stroke prevention expert, Dr. David Spence of The University of Western Ontario, nutrition expert Dr. David Jenkins of the Risk Factor Modification Centre at St. Michael's Hospital in Toronto, and cholesterol expert Dr. Jean Davignon of the Clinique de nutrition métabolisme et athérosclérose in Montreal.

"We wanted to put cholesterol into perspective, as there's been a widespread misconception developing among the Canadian public and even physicians, that consumption of dietary cholesterol and egg yolks is harmless," says Dr. Spence, a professor and scientist at the Schulich School of Medicine & Dentistry, Robarts Research Institute. "Much of this has to do with effective egg marketing."

The review comments on the difference between fasting cholesterol and dietary cholesterol levels. It also discusses two large studies which showed no harm from egg consumption in healthy people. The authors point out that in both studies, those who developed diabetes while consuming an egg a day doubled their risk of cardiovascular disease compared to those eating less than an egg a week. The studies also showed a significant increase of new onset diabetes with regular egg consumption.

The authors conclude, "There is no question that egg white is classed as a valuable source of high-quality protein. Egg yolks, however, are not something that should be eaten indiscriminately by adults without regard to their global cardiovascular risk, genetic predisposition to heart attacks and overall food habits."

Nearly all depressed adolescents recover with treatment, but half relapse

2010-11-02

DURHAM, N.C. – A study of adolescents who had a major depressive disorder found that nearly all recovered from their episode after treatment. But within five years, nearly half of them had relapsed, and females were at much higher risk of another major episode, researchers at Duke University Medical Center found. "We need to learn why females in this age range have higher chances of descending into another major depression after they have made a recovery," said John Curry, Ph.D., lead author of the study and professor in the Duke Department of Psychiatry and Behavioral ...

Having oral sex increases likelihood of intercourse among teens

2010-11-02

Half of teens who have oral sex during the ninth grade will have intercourse by the end of the 11th grade, and most sexually active teenagers will begin engaging in oral sex and sexual intercourse within the same six-month period, according to findings from a new survey conducted by researchers at UCSF and UC Merced. The study is the first to track teens' sexual behavior over time to determine whether oral sex increases the likelihood of having sexual intercourse or acts as a protective measure delaying the onset of further sexual activity. The data, explain the researchers, ...

Study finds fat hormone's long-sought link to heart protection

Click here for more information. LA JOLLA, Calif., November 1, 2010 – One of the many advantages of maintaining a normal body weight is having healthy fat, which in turn supports a healthy heart. Fat tissue is increasingly seen as more than just a storage depot – it's also an active ...

Majority of community facilities performing breast MRI exams meet ACRIN and EUSOBI technical requirements

2010-11-02

An overwhelming majority of Breast Cancer Surveillance Consortium (BCSC) facilities performing breast magnetic resonance imaging (MRI) in the U.S. are up-to-par with American College of Radiology Imaging Network (ACRIN) and European Society of Breast Imaging (EUSOBI) technical standards and requirements, according to a study in the November issue of the Journal of the American College of Radiology (www.jacr.org). The BCSC is a collaborative effort to improve breast cancer research. It consists of five mammography registries and two affiliated sites with linkages to pathology ...

Study of babies' brain scans sheds new light on the brain's unconscious activity and how it develops

2010-11-02

Full-term babies are born with a key collection of networks already formed in their brains, according to new research that challenges some previous theories about the brain's activity and how the brain develops. The study is published today in the journal Proceedings of the National Academy of Sciences. Researchers led by a team from the MRC Clinical Sciences Centre at Imperial College London used functional MRI scanning to look at 'resting state' networks in the brains of 70 babies, born at between 29 and 43 weeks of development, who were receiving treatment at Imperial ...

Arthritis drugs could help prevent memory loss after surgery

2010-11-02

Anti-inflammatory drugs currently used to treat diseases such as rheumatoid arthritis may also help prevent cognitive decline after surgery, according to a new study led by researchers at UCSF and colleagues at Imperial College, London. The research explains for the first time why many patients experience memory loss or other forms of cognitive dysfunction after surgery or critical illness, a process the researchers traced to a specific inflammatory response in the brain. The findings could lead directly to human clinical trials in as short as 12 months, the authors ...

Peptide being tested to treat atherosclerosis inhibits ovarian cancer growth

2010-11-02

A drug in testing to treat atherosclerosis significantly inhibited growth of ovarian cancer in both human cell lines and mouse models, the first such report of a peptide being used to fight malignancies, according to a study by researchers at UCLA's Jonsson Comprehensive Cancer Center. The study follows previous discovery by the same group showing that a protein called apolipoprotein A-I (apoA-I) in patients may be used as a biomarker to diagnose early stage ovarian cancer, when it typically is asymptomatic and is much easier to treat. These earlier findings could be ...

Earth's first great predator wasn't

2010-11-02

Boulder, CO, USA - The meters-long, carnivorous "shrimp" from hell that once ruled the seas of Earth a half billion years ago may have been a real softy, it turns out. A new 3-D modeling of the mouth parts of the Anomalocaris, along with evidence that these parts were not hard like teeth, but flexible, shows that the famed predator could not have been munching on the hard shells of trilobites and other such creatures of the early seas. What's more, there is no evidence from fossilized stomach contents or feces that Anomalocaris' ate anything hard enough to leave a fossilized ...

How lead gets into urban vegetable gardens

2010-11-02

Boulder, CO, USA - One common mitigation approach is to build a raised bed and fill it with freshly composted, low-lead soil from elsewhere, right? Maybe not, according to researchers studying the mysterious case of the lead contamination found within raised beds in community gardens in the Boston communities of Roxbury and Dorchester. "Raised beds are surrounded by a sea of contaminated soil," said Daniel Brabander of Wellesley College. Brabander, his students and colleagues have been studying the lead in 144 backyard gardens in coordination with The Food Project, an ...

Morrison Natural History Museum discovers baby sauropod tracks

2010-11-02

Morrison, CO, USA–Staff at the Morrison Natural History Museum have again discovered infant dinosaur footprints in the foothills west of Denver, Colorado, near the town of Morrison. Dating from the Late Jurassic, some 148 million years ago, these tracks were made before the Rocky Mountains rose, when Morrison was a broad savanna full of dinosaurs. The fossil tracks represent infant sauropods, according to discoverer Matthew Mossbrucker, the museum's director. Sauropods are giant, herbivorous long-necked dinosaurs, sometimes known as "brontosaurs." The sauropod Apatosaurus ...
