[h=1]Watermelon & the Kidney[/h]Watermelon hydrates your body and enables your kidneys to filter out wastes and toxins from your body. Watermelon also contains substances that play a role in kidney function and prevention of certain types of kidney disease. Consult your doctor about the benefits of eating watermelon for your kidneys.
The kidneys are a pair of organs that keep your blood clean and chemically balanced. Each day your kidneys filter approximately 200 quarts of blood and remove 2 quarts of waste products and excess water through your urine. Without proper-functioning kidneys, your body would be unable to remove wastes from food and muscle breakdown that you no longer need. Instead, these wastes would build up in the blood and increase your risk of severe health problems. Kidney diseases affect the ability of your kidneys to filter out wastes. Diabetes and high blood pressure are the two most common causes of kidney disease.

Watermelon contains 92 percent water to hydrate your body. One cup of raw watermelon contains 170 mg of potassium and only 2 mg of sodium. Potassium and sodium are minerals that help regulate your blood pressure and fluid balance. Whereas sodium increases blood pressure, potassium can play a role in lowering blood pressure, according to an American Heart Association Nutrition Committee report published in "Circulation" in August 1998. Reducing your blood pressure lowers your risk of kidney disease.

Nitric Oxide
Eating watermelon increases your levels of nitric oxide and lowers your risk of kidney disease. Watermelon, particularly the rind, is a rich source of citrulline, according to research from the United States Department of Agriculture in University, Missouri, and published in the "Journal of Chromatography A" in June 2005. Citrulline is an amino acid that your body converts to arginine, which is converted to nitric oxide. This gas increases blood flow and reduces blood pressure. A deficiency of nitric oxide is associated with an increased risk of chronic kidney disease, according to research from the University of Florida College of Medicine in Gainesville and published in the "American Journal of Physiology and Renal Physiology" in January 2008. The scientists report that nitric oxide deficiency occurs due to limitations in arginine availability.

Watermelon is a rich source of lycopene, an antioxidant that reduces oxidative stress in the kidneys. One cup of watermelon contains 6,889 mcg of lycopene. There have not been specific studies on lycopene from watermelon and the kidneys, but there has been research on the association between lycopene from tomatoes and kidney disease. Scientists at Firat University in Elazig, Turkey, found that lycopene has protective effects against kidney toxicity, according to research published in "Nutrition and Cancer" in April 2011.
