Potassium deficiency is mostly caused by hypokalemia. Serum potassium concentration below 3.5 mmol/L is called hypokalemia.

Eat more foods rich in potassium, especially fruits and vegetables. Fruits rich in potassium include bananas, strawberries, oranges, grapes, grapefruit and watermelons. Vegetables such as spinach, yam, edamame, amaranth and green onion are also rich in potassium.

All kinds of fruit juices, especially orange juice, are also rich in potassium, which can supplement water and energy.

Tea contains potassium 1. 1%~2.3%, so tea is the best drink in summer.

It should be noted that a high-potassium diet is not suitable for everyone. Acute and chronic renal insufficiency, little or no urine, potassium can not be excreted in time; Shock or adrenal insufficiency can not only supplement potassium, but also control potassium intake.
