A study of more than 2,000 women has found those with higher vitamin D levels showed fewer aging-related changes in their DNA, as well as lowered inflammatory responses.
A second study, examining almost 1,000 patients in West Africa, showed that low vitamin D levels are common among tuberculosis (TB) patients. Lack of vitamin D has been linked in previous studies to multiple sclerosis, rheumatoid arthritis, type 1 diabetes, and other diseases.
Cells have built-in DNA clocks, known as telomeres. Measuring the length of these strands of DNA is one way of examining the aging process at a cellular level.
Women with higher levels of vitamin D are more likely to have longer telomeres, and vice versa. This means that people with higher levels of vitamin D may actually age more slowly than people with lower levels of vitamin D.
No wonder vitamin D has a protective effect on so many diseases, ranging from MS and TB, to heart disease and cancer -- it keeps your body young!
How Vitamin D Performance Testing Can Help Optimize Your Health
A robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body.
Is it any wonder then that no matter what disease or condition is investigated, vitamin D appears to play a crucial role? This is why I am so excited about the D*Action Project by GrassrootsHealth. Dr. Heaney is the research director of GrassrootsHealth and is part of the design of the D*action Project as well as analysis of the research findings. GrassrootsHealth shows how you can take action today on known science with a consensus of experts without waiting for institutional lethargy. It has shown how by combining the science of measurement (of vitamin D levels) with the personal choice of taking action and, the value of education about individual measures that one can truly be in charge of their own health.
In order to spread this health movement to more communities, the project needs your involvement. This was an ongoing campaign during the month of February, and will become an annual event.
To participate, simply purchase the D*Action Measurement Kit and follow the registration instructions included. (Please note that 100 percent of the proceeds from the kits go to fund the research project. I do not charge a single dime as a distributor of the test kits.)
As a participant, you agree to test your vitamin D levels twice a year during a five-year study, and share your health status to demonstrate the public health impact of this nutrient. There is a $65 fee every six months for your sponsorship of this research project, which includes a test kit to be used at home, and electronic reports on your ongoing progress. You will get a follow up email every six months reminding you "it's time for your next test and health survey."
