Papaya is a health and beauty treatment in every bite. Besides its deliciously sweet and juicy flavor, the papaya contains enzymes that help heal minor skin burns, prevent nausea and motion sickness, and boost metabolism. In addition, this fruit is a good source of fiber and contains vitamins A, C, and E, the antioxidant trio. Papaya seeds are the bonus that most people overlook. Don't toss those papaya seeds into the trash! They're entirely edible, though a little peppery, and contribute a touch of spice to a delicious salad dressing.
