Potassium plays a huge role in the health of our heart muscles and nerve cells. And high levels of this element in the blood cause hyperkalemia. If you consume meals high in potassium, your doctor may advise you to decrease portion sizes and concentrate on fruits and vegetables with a lower potassium content. Here is a list of foods rich in potassium that must be avoided if you have hyperkalemia. Yogurt and dairy products A serving of nonfat yogurt weighing eight ounces has roughly 625 mg of potassium, making it one of the dairy aisle’s highest sources of potassium. Even reduced fat milk contains 366 mg of potassium in a glass of cow’s whole milk. Ricotta and cottage cheese are also high in potassium. Goat cheese is a low potassium food, proving that not all cheeses are made equal. Likewise, About 131 milligrams of potassium may be found in a half cup of vanilla ice cream. Bananas When people consider foods high in potassium, bananas frequently come to mind. A banana normally contains 422 mg of potassium. Among all the fruit, bananas are athletes’ favorite as they provide energy. However, it could be highly dangerous for someone suffering from hyperkalemia. Consult your doctor if you have hyperkalemia and stick to fruits such as apples and berries.
