Increasing potassium in our diets as well as cutting down on salt will reduce blood pressure levels and the risk of stroke, research in the British Medical Journal suggests.

One study review found that eating an extra two to three servings of fruit or vegetables per day — which are high in potassium — was beneficial. A lower salt intake would increase the benefits further, researchers said.

While the increase of potassium in diets was found to have a positive effect on blood pressure, it was also discovered to have no adverse effects on kidney function or hormone levels, the research concluded.

As a result, the World Health Organization has issued its first guidelines on potassium intake, recommending that adults should consume more than 4g of potassium per day.

刊登在《英國醫學期刊》的研究顯示,在我們的飲食中增加鉀並減少鹽分,可降低血壓和中風風險。

一份研究評估發現,每天多吃二到三份富含鉀的蔬果有益健康。研究人員說,降低鹽的攝取好處更多。

研究總結說,在飲食中增加鉀被發現對血壓有正面效果,對腎臟功能或荷爾蒙值也沒有不利影響。

因此,世界衛生組織發布第一份鉀攝取指南,建議成人每天攝取四克以上的鉀。
