Magnesium may cut smokers' stroke risk

Magnesium may cut the risk of cerebral infarction in men who smoke, Swedish research suggests.

The findings come from a study of 26,556 Finnish male smokers aged 50-69 without a history of stroke. Diet was assessed, alongside medical history, smoking and physical activity.

During an average follow-up of 13.6 years, 2,702 of men had cerebral infarctions. A further 663 had other forms of stroke.

After adjusting for age and cardiovascular risk factors, the researchers found that men who consumed high levels of magnesium (average daily intake of 589mg) were 15 per cent less likely to have a cerebrovascular infarction than those who consumed least (average daily intake of 373mg).

This association was strongest in men younger than 60.
