Magnesium and Stroke Risk Reduction
Researchers at the Karolinska Institut in Stockholm conducted a meta-analysis to establish the association between magnesium intake and reduced risk of stroke. Previous studies have been unable to conclusively determine the role of magnesium in stroke risk.
The findings will be published in the February 2012 issue of the American Society for Nutrition.
Seven studies were included in this large scale meta-analysis. In total, 241,378 individuals participated in the studies, with 6,477 cases of stroke.
The researchers noted that every increase of 100 mg/day of magnesium was associated with an 8% reduction in total stroke risk and a 9% reduction in ischemic stroke. In an ischemic stroke, blood supply to part of the brain is decreased. No association was seen between magnesium and other forms of stroke.
The researchers believe that these results could come from a few potential effects of magnesium, including lowering blood pressure and magnesium's ability to reduce the risk of type-2 diabetes. They noted that more research is needed to determine the exact mechanism behind the health benefits seen here.
This is not the first study to reveal a health benefit of magnesium. Magnesium intake has also been linked to helping with bone development, healthy teeth, detoxification and lowering the risk of cardiovascular disease.
A supplement is an effective way to get your daily magnesium but there are also many dietary sources of magnesium such as green leafy vegetables, meats, starches, grains, nuts and milk.
