Refreshing and sweet, watermelon is a summertime staple. Packed with vitamins A and C, as well as potassium, watermelon can help keep you hydrated and protect your skin from sun damage. The high water content in watermelon also makes it a great choice for aiding digestion and promoting healthy bowel movements. Additionally, watermelon contains lycopene, an antioxidant that has been linked to reducing the risk of certain types of cancer.
