Benefits of Grapefruits
Good Source of Potassium
One cup of grapefruit juice contains 11 percent of the potassium your body requires daily. Potassium, an electrolyte, helps control muscle contractions, which makes it critical for maintaining normal heart and digestive functions. Many Americans consume an excess amount of sodium, which increases your potassium needs, so if there is a lot of sodium in your diet consider drinking more grapefruit juice.
