Antioxidants v stroke.

The Italian segment of EPIC (European Prospective Investigation into Cancer and Nutrition) has reported on how consumption of antioxidants relates to stroke risk.

Dr Nicoletta Pellegrini of the University of Parma analysed data on roughly 42,000 men and women who were free from stroke and heart attacks at the start of the study, and who were followed for an average of 8 years.

Those with a diet high in antioxidants had a 60% lower chance of suffering an ischemic stroke (blocked blood vessel). Most of this effect may be due to high vitamin C intake.

The researchers speculated that the protective mechanism might be a combination of anti-inflammatory action, plus generation of nitric oxide to cause dilation of blood vessels and so lower blood pressure.

However, highest intake of vitamin E appeared to be linked to a large increase in risk for hemorrhagic stroke (bleeding), but due to the small number of such events, the team suggested further research would be required to investigate this.

More than half the antioxidants consumed came from coffee, red wine and fruit, with other sources including chocolate, vegetables, whole grain cereals and nuts.

While the team checked results after adjusting for a number of risk factors, one notable item they did not account for was sodium (salt) consumption.
