VITAMIN D UPDATE: Study suggests vitamin D may prevent prostate tumor growth. “New evidence suggests spending more time in the sun could make things brighter for men with prostate cancer. Researchers have found that vitamin D can help block a protein that causes prostate cancer tumors to grow. . . . A University of Colorado Cancer Center study recently published in the journal Prostate presents new evidence that vitamin D may help reduce cancer-causing inflammation. Scientists found that the gene GDF-15 – known to be up-regulated by vitamin D – can help block a protein which stimulates tumor growth. . . . Low vitamin D levels can pose certain health risks including cancer, increased risk of death from cardiovascular disease and cognitive impairment in older adults.”
