Drinking too much can have negative effects though
Drinking just two cups of coffee a day can significantly reduce the risk of stroke, new research suggests.
It has previously been thought that caffeine can aggrevate the risk and has been debated many times over the years about the risk a cup of Jo actually has.
Scientists at the Karonlinska Institute in Stockholm, Sweden pooled results of earlier studies to find a definitive answer.
The gathered statistics from eight studies surveying nearly half-a-million people, carried out from the mid 1960s to 2011.
The results found that those drinking two cups a day were 14 per cent less likely to suffer a clot on the brain and drinking three-to-four cups a day reduced the dangers by 17 per cent.
However, the research, published in the American Journal of Epidemiology, found that caffeine addicts drinking six or more cups daily see a reduction in risk of just seven per cent.
The scientists said: "Coffee is a complex mixture of substances that may have both beneficial and harmful effects."
They explained that coffee may protect blood vessels in the brain from damage caused by lipoprotein - which transports fat around the body.
