Magnesium Intake May Prevent Cerebral Infarction in Smokers
03/13/2008
STOCKHOLM, Sweden—According to a recent study at the National Institute of Environmental Medicine, Karolinska Institute (Arch. Int. Med. 2008;168(5): 459-465), a high magnesium intake may play a role in the primary prevention of cerebral infarction in male smokers. The relationships of dietary magnesium, calcium, potassium and sodium intake with risk of stroke in a cohort of 26,556 Finnish male smokers, aged 50 to 69 years, who were stroke-free at baseline was examined. During a mean follow-up of 13.6 years (1985 to 2004), 2,702 cerebral infarctions, 383 intracerebral hemorrhages, and 196 subarachnoid hemorrhages were identified in the national registries. After adjustment for age and cardiovascular risk factors, a high magnesium intake was associated with a statistically significant lower risk of cerebral infarction, but not with intracerebral or subarachnoid hemorrhages.
