香蕉中含有丰富的钾离子,经常食用既能通便润肠,又能预防高血压。《英国医学杂志》刊登的一项新研究发现,经常吃香蕉,少吃油炸薯片,有助于降低中风死亡危险。一项新研究对涉及12.8万人的33项试验结果进行了梳理分析。结果发现,当参试者增加钾摄入量的时候,其高血压情况明显改善。增加钾摄入量可以使中风危险降低24%。早期研究数据显示,老年人肾脏功能较差,血液中钾的代谢相对较差,大量进食香蕉等富含钾的食物可能有害健
Banana is rich in potassium ions, regular consumption of both laxative intestine, but also to prevent high blood pressure. A new study published in the British Medical Journal found that eating bananas regularly and eating less fried potato chips helped to reduce the risk of stroke. A new study analyzed the results of 33 trials involving 128,000 people. The results showed that when the participants increased potassium intake, their hypertension significantly improved. Increasing potassium intake can reduce the risk of stroke by 24%. Earlier studies showed that the elderly have poorer kidney function and relatively poor metabolism of potassium in the blood, which may be harmful to large amounts of potassium-rich foods such as bananas
