A new study of longevity has confounded a long held assumption about vitamin D deficiency.
Low levels of vitamin D have been correlated in the past with a variety of age-related diseases. And though causality has not been determined, it was generally assumed. This new study compared levels of vitamin D in the offspring of long-lived adults (nonagenarians), who have a lower propensity for age-related diseases and a higher liklihood of reaching old age.
What they discovered was that these people had significantly lower levels of vitamin D in their system, and this correlation was independent of other factors.
Although this doesn’t suggest that you should avoid vitamin D for a longer life, it does throw into doubt the long assumed connection between low levels of vitamin D and disease.
