Watermelon is rich in nutrients – including vitamins A and C, B vitamins and potassium — but where it really packs a punch is with lycopene, the antioxidant pigment that gives the fruit its deep red color. Some studies suggest that lycopene may have cardiovascular benefits, including a reduced risk of stroke, and eating watermelon may slightly lower blood pressure. Researchers have also looked at lycopene’s possible role in protecting against various cancers, though evidence is scant.
