When you cut a papaya, the insides look very inviting, and the seeds can easily be scooped out. They are high in fat and protein, and contain plenty of calcium, magnesium and phosphorus. Think twice before you discard them, as they can be used in many ways. According to Maryland Medical Center and Asian Pacific Journal of Tropical medicine, papaya seeds are great for getting rid of intestinal parasites. A recent study showed that people who were taking honey together with papaya seeds, cleared their stool of parasites in 23 out of 30 cases. Papaya seeds are also credited with anti-cancerous properties. The seeds have a distinct, slightly peppery flavor. They can be eaten as they are, or you can sprinkle them over salads and other dishes, just as you would use pumpkin seeds. Those who are not afraid of the spicy flavor, can try them in a smoothie.
