It’s fairly obvious that watermelon is full of, well, water, but this juicy melon is also among the richest sources of lycopene, a cancer-fighting antioxidant found in red fruits and vegetables. In fact, watermelon contains more lycopene than raw tomatoesabout 12 milligrams per wedge, versus 3 milligrams per medium-sized tomato.
Although this melon is plenty hydrating on its own, Gans loves to mix it with water in the summertime. “Keep a water pitcher in the fridge with watermelon cubes in the bottom,” she says. “It’s really refreshing, and great incentive to drink more water overall.”
