More Bananas Can Help Ward Off Strokes

                            
                             



Eating more bananas - and cutting down on crisps - could prevent thousands of stroke deaths, say researchers.The potassium-rich fruit helps drive down blood pressure levels, as does lowering your salt consumption in snacks like crisps.A study found people with a high potassium intake had 24 per cent less risk of stroke.

Previous data suggested older people could be harmed by potassium as their kidneys may be less able to remove it from their blood. But the research, on journal website bmj.com, said these fears can be dismissed. It found potassium did not negatively affect kidney function.

The authors said there was ‘high quality evidence’ that people with high blood pressure improved when they increased their potassium intake.They analysed 128,000 people over 33 trials and said consuming more of the mineral, for example by eating bananas, is ‘potentially beneficial to most people’.

Bananas are one of the most common foods to be rich in potassium. Each one contains around 420mg, well on the way to the daily adult allowance of 3,500mg. There are around 53,000 deaths in each year from stroke, with a further 100,000 survivors, some left with severe disability.

Another study on the website found slightly reducing salt intake for four weeks or more led to a significant fall in blood pressure – and so reduced risk of stroke and heart attack. Dr Clare Walton of the Stroke Association said a healthy diet was a key part of managing stroke risk.

She said: ‘High blood pressure is the single biggest risk factor for stroke. Making changes to your diet can go a long way to keeping blood pressure under control.

‘This research suggests that reducing your salt intake and eating more potassium-rich foods such as bananas, dates and spinach could keep your risk down.’The Department of Health advises older people should not take potassium supplements unless advised by a doctor.
