Not Enough Vitamin D
According to new research, one billion people aren’t getting enough vitamin D. Krisha McCoy of HealthDay News reports:
In the July 19 issue of the New England Journal of Medicine, Michael Holick, director of the General Clinical Research Center at Boston University School of Medicine and director of the Bone Healthcare Clinic at Boston Medical Center, published an overview of his work on vitamin D.Vitamin D and the lack of it, is no stranger to DiseaseProof. Check out the Importance of Vitamin D for more. Here’s a taste:
According to Holick, it has been estimated that one billion people in the world are vitamin D deficient or insufficient.
Without vitamin D, only 10 percent to 15 percent of dietary calcium and about 60 percent of phosphorus is absorbed by the body. This can have a direct effect on bone mineral density.
There is evidence that people who live at higher latitudes -- where the angle of the sun's rays is not sufficient to produce adequate amounts of vitamin D in the skin -- are more likely to develop and die of Hodgkin's lymphoma, colon, pancreatic, prostate, ovarian, breast and other cancers. And there is an association between low levels of vitamin D and increased risk for type 1 diabetes, multiple sclerosis, Crohn's disease, hypertension and cardiovascular disease.
Vitamin D also works in concert with a number of other vitamins, minerals, and hormones to promote bone mineralization. Research also suggests that vitamin D is important to maintain a healthy immune system, regulate cell growth, and prevent cancer. Vitamin D has been shown to protect against the development of autoimmune disease such as inflammatory bowel disease, multiple sclerosis, and rheumatoid arthritis. It also has been shown to be helpful in decreasing disease severity for those suffering with autoimmune disease.11. Cantorna MT, Zhu Y, Froicu M, Wittke A.
