Although melons are mainly carbohydrates and water, their health claims aren't all wet. Watermelon contains high concentrations of lycopene, an antioxidant that may help reduce risks of certain cancers. Lycopene is the pigment that gives watermelon flesh its red color.

Also, a 2-cup serving of watermelon contains 20 percent of the daily recommended intake of vitamin A, 30 milligrams of vitamin C, 1.5 grams of fiber, 353 milligrams of potassium, 1 gram of fat and no cholesterol, in just 97 calories.

Orange-fleshed melons, such as cantaloupe, are a good source of vitamin A and carotenoids (also found in carrots). Many health studies link carotene-rich foods to disease prevention. Both honeydew and cantaloupe are rich in vitamin C.

What about melon etiquette? In her book, "Emily Post's Etiquette," Elizabeth Post states, "Watermelon is cut into large-size pieces, or slices, and usually eaten with the fingers. If using a fork, remove seeds with the tines and cut the pieces with the side of the fork."

If any seeds end up in your mouth, you should inconspicuously get them into a spoon, and from the spoon, to your plate, says Post. Apparently, seed-spitting contests are not for polite circles.
