Low vitamin D linked with stroke

In recent years, more and more evidence shows that lower vitamin D status is associated with several known risk factors of stroke. This study undertook a systematic review and a meta-analysis of Nineteen previous studies and found a between a 62 and 145% increased risk of stroke for people with the lowest Vitamin D levels.
So go out and get some more sun and some rich fatty vitamin D rich foods. Vitamin D is a fat soluble vitamin.
Stroke is the second leading cause of death among people aged 60 years and above, and is causing a substantial global disease burden. Based on the global burden disease (GBD) 2013 study, about 6.5 million people died from stroke and 10.3 million people suffered a stroke in 2013. That is a lot. China had about 2.4 million incidences of stroke each year and bore the heaviest burden of stroke across the world. Other factors include hypertension, diabetes, obesity, and tobacco use.
Vitamin D, which is classically known as a protective factor in bone metabolism, in recent years has been reported to play a vital role in cardiovascular health.
Some evidence also supported the hypothesis that low vitamin D intake may function as a predictor of long-term incidence of stroke
