The King's team looked at white blood cells, which tend to experience faster rates of turnover - and faster shortening of telomeres - when the body's tissues are suffering more inflammation.
They looked at a total of 2,160 women aged between 18 and 79, and took a snapshot measurement of the levels of vitamin D in their bloodstream, comparing this to the length of the telomeres in their white blood cells.
They found that, after adjusting the results for the age of the volunteer, women with higher levels of vitamin D were more likely to have longer telomeres in these cells, and vice versa .... http://news.bbc.co.uk
