鉀 Potassium

Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke.

Adults (19 to 64 years) need 3,500mg of potassium a day. You should be able to get all the potassium you need from your daily diet. Taking too much potassium can cause stomach pain, nausea and diarrhoea.

我國目前尚未訂定鉀的建議攝取量，可參考世界衛生組織建議成人每日 3,510 毫克，及美國 DRIs 建議足夠攝取量每日 4,700 毫克。

WHO recommends an increase in potassium intake from food for reduction of blood pressure and risk of cardiovascular disease, stroke and coronary heart disease in adults (strong recommendation). WHO suggests a potassium intake of at least 90 mmol/day (3510 mg/day) for adults.

減鈉鹽中常用氯化鉀取代氯化鈉降低鈉含量，所以減鈉鹽才會含有鉀成分

每人每日約吃10公克減鈉鹽，鉀的攝取量相等於吃下3根香蕉，屬合理範圍，並無風險

低鈉鹽是用鉀取代鈉，腎不好的人不能亂吃
