Besides protecting from cancer, obesity, autoimmune diseases and cardiovascular problems, vitamin D helps build strong bones. And scientists have found this health building vitamin has a remarkable impact on the immune system, too. Vitamin D, it turns out, is necessary for the production of anti-microbial peptides, substances that fight off infection-causing bacteria, fungi, and viruses when these pathogens try to move into organs and through mucous membranes.
In fact, previous research has shown adequate vitamin D can help prevent colds and flu as well as serious lung infections, including tuberculosis. Now Swedish researchers from the Karolinska Institute and Karolinska University Hospital in Stockholm have evidence that higher vitamin D levels offer especially strong protection against another common health problem — urinary tract infections (UTIs).

On November 20th, the “prestigious” Institute of Medicine of the National Academies of Science (IOM) issued its eagerly awaited report on Dietary Reference Intakes for Calcium and Vitamin D. According to the study brief, “Calcium and vitamin D are two essential nutrients long known for their role in bone health. But since 2000, the public has heard conflicting messages about other benefits of these nutrients — especially vitamin D — and also about how much calcium and vitamin D they need to be healthy.” And in fact, it was to help clarify this issue that the United States and Canadian governments asked the IOM to assess the current data on health outcomes associated with calcium and vitamin D, as well as update the nutrient reference values, known as Dietary Reference Intakes (DRIs).
How much vitamin D do you really need? If you ask the Washington DC-based Institute of Medicine (IOM), it’s not much. In fact, their new recommendation is a mere 600 IU, up from the paltry 400 IU the government had previously recommended.(1)
The IOM also thinks that most people are already getting enough vitamin D from the sun and their diets. (more…)
