Potassium, calcium, and magnesium intakes and risk of stroke in women.

"...Calcium intake was positively associated with risk of intracerebral hemorrhage (for highest vs. lowest tertile, adjusted relative risk = 2.04, 95% CI: 1.24, 3.35). These findings suggest that potassium and magnesium intakes are inversely associated with the risk of cerebral infarction among hypertensive women." https://www.ncbi.nlm.nih.gov/pubmed/21540318
