This unique watermelon is different because of its bright orange-colored flesh, which has a crisp, juicy texture and a flavor that can vary from mildly sweet to super sweet. In fact, Orange watermelons may be substituted for Red watermelon or any other sweet melon. It is worth noting that all watermelons are high in lycopene, which is a potent antioxidant studied extensively for its ability to protect men against prostate cancer. Try pairing your watermelon with some iced green tea — the antioxidants found in both may help prevent cancer in the way they work together in the body.
