The grapefruit was created in the 18th century by crossing an orange with a pomelo. The result was a fruit that grew in clusters similar to grapes, hence the name grapefruit. Most people think of grapefruit as a healthy, delicious, and nutritious part of their diet. After all this large citrus fruit is packed full of vitamin C. In fact eating one half of a grapefruit will provide you with approximately 63-percent of your daily requirement of vitamin C and only 52-calories. Grapefruit is an excellent source of disease fighting antioxidants such as lycopene and beta-carotene. The fruit also contains minerals such as manganese, zinc and copper as well as phytonutrients, which promote health.
Possible health benefits of grapefruit include weight loss, decreased risk of stroke, cancer, asthma, high blood pressure, and clearer skin. Despite all these potential health benefits people need to be cautious when consuming this supposed ‘super fruit’ because grapefruit can be harmful to your health in the following ways…
Although some scientific research has found that grapefruit may reduce the incidence of kidney stones due to its acidic properties, other research has shown grapefruit can be harmful to those with pre-existing renal disease. This is because grapefruits contain large amounts of potassium.
Excess potassium can be harmful if your kidneys are already compromised in their functioning. The kidneys are supposed to filter excess minerals from your blood. Hyperkalemia results when high levels of potassium collect in the blood and your kidneys are unable to remove it. Severe hyperkalemia can lead to cardiac arrest and death. Therefore, if you have renal disease you should be cautious of including excessive amounts of grapefruit in your diet.
