Vitamin D

Aggressive prostate cancer caused by vitamin D deficiency, scientists now declare

Men with suboptimal or deficient levels of vitamin D are much more likely than other men to develop prostate cancer, according to a new study funded by the U.S. National Institutes of Health (NIH) and the Department of Defense (DoD). Researchers from Northwestern University near Chicago found that vitamin D deficiency can increase the risk of aggressive prostate cancer in some men by nearly 500 percent, highlighting the need for increased focus on natural sunlight exposure and supplementation.

Science proves that avoiding sunshine doubles your risk of death

The merits of regular sun exposure for optimal health have been reiterated by one of the most comprehensive studies yet to look at the connection between vitamin D and early mortality. Researchers from Sweden, after compiling the results of a 20-year research project they started back in the early 1990s, found that avoiding natural sunlight, or slathering yourself with sunscreen every time you go outside, can actually double your risk of premature death.

Losing weight can significantly improve vitamin D levels in obese women

It's known in the health community that obesity increases one's risk of getting cancer, heart disease and diabetes, but there is more to the story than just weight gain. In fact, in a new study, blood samples of most obese individuals (70 percent) showed low vitamin D levels. That correlation is significant, since vitamin D is a fat-soluble nutrient.

3 essential components required for true health

Calcium, vitamin D supplementation improves cholesterol in postmenopausal women

Maintaining high blood levels of 25-hydroxyvitamin D (25(OH)D), which is said to be the most accurate indicator of vitamin D levels inside the body, appears to play a prominent role in mitigating inflammation and keeping cholesterol in check. Researchers from the Women's Health Initiative, publishing their findings in the online journal Menopause, found that postmenopausal women with the highest vitamin D levels fared the best in terms of cholesterol levels, suggesting that vitamin D could help prevent cardiovascular events.

High vitamin D levels in pregnant women lead to stronger babies

Children born to mothers with high vitamin D levels during pregnancy are significantly stronger at four years of age, according to a study conducted by researchers from the University of Southampton and published in the Journal of Clinical Endocrinology and Metabolism in January.

Science proves that low vitamin D leads to bone fractures

A new study out of Scandinavia has affirmed the importance of maintaining high vitamin D levels for healthy bones. Researchers from Sweden, after observing more than 1,000 elderly women over a 10-year evaluation period, learned that those who maintained consistent blood levels of serum 25-hydroxyvitamin D (25OHD) above 50 nanomoles per liter (nmol/l) had nearly half the risk of suffering a bone fracture or osteoporosis compared to those with less than 50 nmol/l of 25OHD.

Americans in low-income, overweight and minority groups more susceptible to vitamin D, calcium deficiency

Millions of Americans are unable to meet recommended daily intakes of calcium and vitamin D because of socioeconomic conditions, even though they are vital nutrients in bone health during all phases of life, new research indicates.
