Vitamin D Crucial To Activating Immune Defenses

Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system -- T cells -- will not be able to react to and fight off serious infections in the body.

Vitamin D Levels Linked With Health Of Blood Vessels

A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, research from the Emory/Georgia Tech Predictive Health Institute has found.

Treating Vitamin D Deficiency Significantly Reduces Heart Disease Risk, Studies Find

Preventing and treating heart disease in some patients could be as simple as supplementing their diet with extra vitamin D, according to two new studies at the Intermountain Medical Center Heart Institute in Murray, Utah. Researchers...

Hungry Immune Guardians Are Snappier: Nutrition Has A Direct Influence On...

Bonn researchers have discovered an elementary mechanism which regulates vital immune functions in healthy people. In situations of hunger which mean stress for the body's cells, the body releases more antimicrobial peptides in order to protect itself. The scientists will publish their results in the journal Nature.

Identical Twins May Not Be So Identical When It Comes To...

Identical twins may share appearances, mannerisms, even clothes — but the microbes living in their guts are anything but the same. By comprehensively sequencing microbial genes in the gut, researchers have found that communities of bacteria in adult identical twins differ dramatically.

Vitamin D Insufficiency Prevalent Among Psoriatic Arthritis Suffers

New research reports a high prevalence of vitamin D insufficiency and deficiency among patients with psoriatic arthritis. Seasonal variation in vitamin D levels was not observed in patients in southern or northern locations. The findings published in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), also show no association between disease activity and vitamin D level.

Well-Defined Quantity Of Antioxidants In Diet Can Improve Insulin Resistance, Study...

A diet rich in natural antioxidants improves insulin sensitivity in insulin-resistant obese adults and enhances the effect of the insulin-sensitizing drug metformin, a preliminary study from Italy finds.

High Levels of Vitamin D In Older People Can Reduce Heart...

Middle aged and elderly people with high levels of vitamin D could reduce their chances of developing heart disease or diabetes by 43%, according to researchers at the University of Warwick.

Caucasians Who Avoid Sun Exposure More Likely To Be Vitamin D...

Light-skinned people who avoid the sun are twice as likely to suffer from vitamin D deficiency as those who do not, according to a study of nearly 6,000 people by researchers at the Stanford University School of Medicine. Surprisingly, the use of sunscreen did not significantly affect blood levels of vitamin D, perhaps because users were applying too little or too infrequently, the researchers speculate.

Nutrition’s Potential To Save Sight

While 20/20 vision is a symbol of visual acuity, between now and the year 2020, more and more people will experience some extent of vision loss due to age-related macular degeneration (AMD) and other sight-robbing diseases.

Scientists Pinpoint How Vitamin D May Help Clear Amyloid Plaques Found...

A team of academic researchers has identified the intracellular mechanisms regulated by vitamin D3 that may help the body clear the brain of amyloid beta, the main component of plaques associated with Alzheimer's disease. Published in the March 6 issue of the Journal of Alzheimer's Disease, the early findings show that vitamin D3 may activate key genes and cellular signaling networks to help stimulate the immune system to clear the amyloid-beta protein.
