Dulcinea Farms in California recently launched a push to sell its PureHeart mini-seedless watermelon year-round on the east coast at stores such as Giant, Safeway, Wegmans and Harris Teeter.

Mangoes, grapes, cherries and pears all have more grams of sugar per serving than watermelon. But watermelon still has about 17 grams per slice, so it's best not to load up on too much of it at once.

“Watermelon” is a fitting name, because it’s more than 91 percent water. When you eat an average-size wedge (10 ounces or so), you’re effectively drinking a full cup of water.

Watermelon has a host of health benefits including protecting one's joints from inflammation and improving digestive conditions. It's also 90% water.
