Watermelon-A high antioxidant Fruit



Watermelon is the most common fruit in the Philippines during summer season and are called as the thirst quenching fruit. They are round, oblong, or even square. watermelons can also have yellow flesh.

Watermelon is packed with some of the most important antioxidants that are found in nature that helps in the conditions like colon cancer, asthma, diabetes, and arthritis.

It is rich in vitamin C and vitamin A. It also contains concentrated source of the carotenoid, lycopene. The antioxidant function of lycopene helps to protect cells and other structures in the body from oxygen damage-has been linked in human research to prevention of heart disease.

Watermelon is also rich in the B vitamins necessary for energy production. The cooling fruit is exceptionally high in citrulline, an amino acid our bodies use to make another amino acid, arginine, which is used in the urea cycle to remove ammonia from the body, and by the cells lining our blood vessels to make nitric oxide.

Nitric oxide not only relaxes blood vessels, lowering high blood pressure, it is the compound whose production is enhanced by Viagra to prevent erectile dysfunction. Arginine has been shown to improve insulin sensitivity in obese type 2 diabetic patients with insulin resistance.
