More vitamin D, longer life

Most disease studies have focused on people of European descent, doctors said. In one study, researchers measured vitamin D levels in 2,638 Caucasians and African-Americans aged 71 to 80.
African-Americans had lower vitamin D levels than Caucasians. After 8.5 years of follow-up, those with very low levels of vitamin D—less than 20 nanograms per milliliter of blood—were 50 percent more likely to have died from any cause compared to those with higher levels. Doctors said the good news is it’s easy to raise vitamin D levels through diet and supplements.
