Oranges have many benefits. Here is one: Optimal Heart Function Oranges provide potassium, an electrolyte mineral responsible for normal heart function. Potassium works with other electrolytes, including calcium, magnesium and sodium, to carefully maintain fluid levels both in and around cells. Steady fluid balance allows electricity to conduct through your system, making your heart beat. When potassium levels get too low, you may develop an abnormal heart rhythm, known as an arrhythmia. You need 4,700 milligrams of daily potassium, according to the Linus Pauling Institute. A medium, 2 1/2-inch orange offers nearly 240 milligrams of potassium.
