stroke
January 17, 2008 — A new analysis from a prospective cohort study suggests that higher plasma levels of vitamin C are associated with a reduced risk for stroke. Researchers report that those in the highest quartile for plasma vitamin C had a 42% reduced risk for stroke compared with those in the lowest quartile.
The results, from the prospective European Prospective Investigation into Cancer (EPIC)–Norfolk study, are published in the January issue of the American Journal of Clinical Nutrition.
Whether the causal link between plasma vitamin C and stroke can be identified, plasma vitamin C concentrations may nevertheless be a good predictive indicator of stroke risk, lead author Phyo Kyaw Myint, MRCP, from the clinical gerontology unit at Addenbrooke's University Hospital in Cambridge, United Kingdom, told Medscape Neurology and Neurosurgery.
"Vitamin C is a biomarker of fruit and vegetable consumption, which have many nutrients which may be biologically active and protective for stroke; high fruit and vegetable consumption has been reported in previous studies to be protective for stroke," he said. "Measuring plasma vitamin C levels may identify those who will most benefit from established risk factor management such as blood pressure control.
