If you’re trying to live a healthier life in 2015, you might have tried to cut back on the coffee. There’s good news for fans of a few good grounds, however, as a major new study has revealed that drinking between three and five cups a day can actually make you less at risk of having a heart attack. How’s that for an excuse to put the kettle on or invest in a new Nespresso machine?
The research, which was led by Seoul’s Kangbuk Samsung Hospital, suggests that drinking ‘moderate’ amounts of coffee can stop your arteries becoming clogged. Of the 25,000 people studied, it was those who drank the least and the most coffee who were at the highest risk of suffering from coronary artery calcium, which is a sign of potential clogging of the arteries.
This new study flies in the face of various pieces of past research which have poured scorn on coffee drinking, claiming that it actually increases the heart-disease risk by raising both blood pressure and cholesterol levels. Yet a meta analysis – a study of 356 different pieces of research – actually suggests that moderate consumption can offer the heart protection. The latest international study, published in the Heart BMJ journal, suggests that the three- to five-cup level is the optimum for heart health.
The new research, published online in the journal Heart suggests three to five cups is the optimum amount to drink, followed by drinking between one and three cups. Any more or less and the benefits appear to diminish. Coffee has already been linked with a lowering of type 2 diabetes risk. This is because it is believed to improve insulin sensitivity. Researchers involved in the latest study say there may be a connection between this effect on preventing diabetes and heart health, as the former is known to increase the risk of a person suffering from hardened arteries.
