An icon of summer picnics and gatherings, watermelon is loved by people young and old. In addition to being sweet and refreshing, it is the best summer food for cooling down. It also offers nutritional benefits such as blood pressure reduction and anti-inflammatory effects, providing protection for both the skin and cardiovascular system. However, a few types of people should be cautious when eating watermelon.
Health Benefits of Watermelon
1. Lowers Blood Pressure and Relieves Hangovers
Aptly named, watermelon is about 90 percent water, making it an excellent source of hydration for the body. The potassium found in watermelon can balance body fluids and support kidney function, facilitating the elimination of excess sodium and promoting urine production. Watermelon also contains a natural diuretic substance, L-citrulline, which is converted into arginine in the body. This conversion leads to the production of nitric oxide, which helps dilate blood vessels, promotes blood flow, and facilitates the formation of urine, which can play a diuretic role. In clinical practice, doctors may prescribe diuretics to lower blood pressure in hypertensive patients.
