Mean Serum 25(OH)D Levels Decreasing in All Categories of the US Population - 0 views

  •  
    March 27, 2009 - A significant decrease in serum 25-hydroxyvitamin D (25[OH]D) levels has led to an increase in vitamin D insufficiency in the US population, especially in racial and ethnic groups, according to results of a population-based study reported in the March 23 issue of the Archives of Internal Medicine. "Vitamin D insufficiency has been associated with increases in cardiovascular disease, cancer, and infection," write Adit A. Ginde, MD, from the Department of Emergency Medicine at the University of Colorado Denver School of Medicine, Aurora, Colorado, and colleagues. "Vitamin D supplementation appears to mitigate the incidence and adverse outcomes of these diseases and may reduce all-cause mortality." [...] "These findings have important implications for health disparities and public health," the study authors conclude. "Our data provide additional evidence that current recommendations for vitamin D supplementation (200-600 IU/d) are inadequate to achieve optimal serum 25(OH)D levels in most of the US population." They add that large, randomized controlled trials of higher doses of vitamin D supplementation are needed to evaluate their effect on general health and mortality.

Traffic Triples Heart Attack Risk - WebMD - 0 views

  •  
    March 13, 2009 -- Whether you drive, take the bus, or bicycle, being in heavy traffic triples your risk of heart attack within one hour. Air pollution from car fumes is the likely culprit, suggest Annette Peters, PhD, and colleagues at the Institute of Epidemiology, Helmholtz Center, Munich, Germany. In a previous study, Peters and colleagues found that a sizeable proportion of heart attacks -- about 8% -- could be attributed to being in traffic. To follow up, the researchers interviewed 1,454 people who survived heart attacks. In the hour before their heart attack, many of the survivors had been in heavy traffic. Analysis of the data showed that these heart-attack-vulnerable people were 3.2 times more likely to suffer a heart attack if they'd been in heavy traffic in the previous hour.

Eating Red Meat May Boost Death Risk - WebMD - 0 views

  •  
    March 23, 2009 -- Men and women who eat higher amounts of red meat and processed meat have a higher risk of dying from cancer, heart disease, and other causes compared to those who eat less, according to a new study. Those in the study who ate the most red meat took in about 4.5 ounces a day -- the equivalent of a small steak.

Genetically Altered Mice Stay Lean With High-Carb Diet - 0 views

  •  
    Researchers at the University of California, Berkeley, have identified a gene that plays a critical regulatory role in the process of converting dietary carbohydrates to fat. In a new study, they disabled this gene in mice, which consequently had lower levels of body fat than their normal counterparts, despite being fed the equivalent of an all-you-can-eat pasta buffet. The authors of the study, to be published in the March 20 issue of the journal Cell, say the gene, called DNA-PK, could potentially play a role in the prevention of obesity related to the over-consumption of high-carbohydrate foods, such as pasta, rice, soda and sugary snacks.

Low Vitamin D Hurts Teenagers' Hearts - 0 views

  •  
    March 11, 2009 -- Low vitamin D levels greatly increase a teenager's risk of diabetes and heart disease, Johns Hopkins researchers find. It is becoming clear that adults who get too little vitamin D are at higher risk for diabetes and heart disease. Now, it appears vitamin D levels also affect these risks earlier in life, say Johns Hopkins researchers Jared P. Reis, PhD, and colleagues.

Wine Won't Cut Breast Cancer Risk - 0 views

  •  
    March 9, 2009 -- Red or white wine with dinner? A new study suggests a woman's wine choice should be based on personal preference rather than any hope that a wine's color may affect its breast cancer-fighting ability. "We found no difference between red or white wine in relation to breast cancer risk. Neither appears to have any benefits," researcher Polly Newcomb, PhD, MPH, head of the Cancer Prevention Program at the Fred Hutchinson Cancer Research Center in Seattle, says in a news release.

    new (March 24th) report in Clinical Cancer Research, a journal of the American Association for Cancer Research, shows that Omega-3 fatty acids appear protective against advanced prostate cancer. Dr. John S. Witte, Ph.D., professor of epidemiology and biostatistics at the University of California San Francisco, says that previous research has shown protection against prostate cancer, but that this is one of the first studies to show protection against advanced prostate cancer.

PMID: 19307517 Conclusion Nonvertebral fracture prevention with vitamin D is dose dependent, and a higher dose should reduce fractures by at least 20% for individuals aged 65 years or older.

The Heart Scan Blog: Sterols should be outlawed - 0 views

  •  
    While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim. The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods. Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people. The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building

    NEW YORK (Reuters Health) - Women who get plenty of mushrooms and green tea in their diets may have a lower risk of developing breast cancer, new study findings suggest. The study, of more than 2,000 Chinese women, found that the more fresh and dried mushrooms the women ate, the lower was their breast cancer risk.

New data on link between cancer and nutrition discussed at European symposium - 0 views

  •  
    European experts in cancer and nutrition are meeting in Zurich, Switzerland late this month to discuss cutting-edge research in one of the most important and fiercely debated topics in cancer prevention: the link between diet and cancer. There is growing evidence that many cancers may be prevented through healthy lifestyle, including a nutritionally balanced diet. In addition, nutritional problems can also have a negative impact on cancer management and the lives of patients. Other presentations will include new data on topics such as: Childhood nutrition and later breast cancer risk The anti-tumour effects of green tea Malnutrition and patient distress in cancer Possible anti-tumour effects of soy extracts in mice Estrogens in beef and cancer risk

  •  
    Do you live in a big city or an area where you are sometimes forced to inhale car and truck exhaust? If so, you should strongly consider using a face mask, because exhaust causes arteries to lose their flexibility. Researchers writing in the journal Particle and Fibre Toxicology found that exposure to engine pollution resulted in arterial stiffness in a group of healthy volunteers.
