Ten common foods high in potassium include coffee, oranges, bananas, rape, spinach, potatoes, tomatoes, pecans, enoki mushrooms and hawthorn. In particular, in summer, when the temperature rises, potassium ions are excreted with sweat, which can lead to low potassium and affect the normal physiological activities of the body. At the same time, patients with mild hypokalemia are often advised to consume potassium-rich foods for potassium supplementation. Hypokalemia is most often seen in patients who sweat a lot in a short period of time, have prolonged diarrhea, vomit, and use drugs such as furosemide for a long time. Eating foods high in potassium can effectively improve physical weakness, as well as digestive symptoms, including poor appetite, nausea, and bloating. However, it should be noted that some patients are not suitable to consume such foods, such as those suffering from hyperthyroidism and hyperkalemia, which may aggravate their condition. Pregnant women and nursing mothers should not eat foods high in potassium such as kelp and nori because of their high iodine content, which can enter the fetus and baby with the blood circulation and cause thyroid dysfunction. In addition, there are many foods with high potassium content, such as buckwheat, amaranth, parsley, lettuce, yam and strawberries, oranges, grapes, grapefruit, etc., which can be consumed in moderation according to your own condition and after consulting your doctor, and at the same time, the cause of potassium deficiency should be clarified.
