The cheery red color comes from lycopene, an antioxidant. Studies show it may help curb your risk of cancer and diabetes as part of a healthy lifestyle. Watermelon has more of this nutrient than any other fruit or veggie like tomatoes. To load up on lycopene, choose a melon with bright red flesh rather than yellow or orange. And the riper, the better. Also, seedless melon tends to have more lycopene than those with seeds.
Some pigments help protect plants from the sun. Oddly enough, just eating them may shield your skin, too -- at least a little. The lycopene in watermelon may make it less likely that you get sunburned. But that’s not for sure, so keep using your broad-spectrum sunscreen with SPF of 30 or higher every day. Watermelon is rich in an amino acid called citrulline that may help move blood through your body and can lower your blood pressure. Your heart also enjoys the perks of all the lycopene watermelon contains. Studies show that it may lower your risk of heart attacks. Of course, your whole lifestyle affects your heart health. So make sure you also work out, don’t smoke, limit saturated fat, and keep up with your doctor’s advice.
