Low Vitamin D Tied to Stroke

Tuesday, 29 May 2012 11:53 AM

Eating a diet that’s low in foods containing vitamin D raises the risk of stroke later in life, according to the findings of a new 34-year study of Japanese-American men.
Researchers said the study – published in Stroke, an American Heart Association journal – provides strong evidence that vitamin D may prevent the disease, which strikes nearly 800,000 Americans every year.
"Our study confirms that eating foods rich in vitamin D might be beneficial for stroke prevention," said lead researcher Dr. Gotaro Kojima, with the John A. Burns School of Medicine at the University of Hawaii in Honolulu.
Vitamin D, an essential nutrient, has been shown to prevent bone loss and rickets, and some research has suggested it may also lower the risk of some cancers and diabetes. Sunlight is the biggest source, but vitamin D is also in fortified milk and breakfast cereals, fatty fish and egg yolks.
For the new study, researchers tracked the health of 7,385 Hawaiian men as part of the Kuakini Honolulu Heart Program, which has been monitoring stroke and heart disease among the participants since 1965.
Researchers separated the men into four groups, designated by how much vitamin D they had consumed. They then analyzed the incidence of stroke among them through 1999.
They found the men who consumed the least dietary vitamin D had a 22-27 percent higher risk of stroke, compared to those consuming the highest levels of vitamin D.
Stroke is the fourth leading cause of death in the United States.
