Vitamin D intake may decreases risk of stroke finds study
China: Vitamin D intake decreases the risk of stroke, according to a recent study published in the journal Clinical Nutrition. The study found that 25(OH)D levels and vitamin D intake were both inversely related to stroke risk, with a non-linear dose-response relationship.
Stroke is a disease that affects the arteries leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures).
A large number of studies have shown vitamin D to be related to stroke risk. The dose-response association between vitamin D and stroke risk is unclear. So, Han Shi, Clinical Department One, China Medical University, Shenyang, China, and colleagues conducted a dose-response meta-analysis to evaluate the relationships between 25-hydroxyvitamin D [25(OH)D] level, vitamin D intake, and the risk of stroke by summarizing cohort studies.
