Green papayas have a higher amount of potassium than ripe papayas. Potassium is one of the major electrolytes in the blood (the others are sodium and chloride), carrying a positive electrical charge. Green papayas have higher papain, a protein-digesting enzyme, concentration than ripe ones. The papain along with other enzymes and phytonutrients help improve digestion. Because of their high fiber content, the enzymes present in raw papaya, and the latex, green papayas are perfect for naturally cleaning the digestive system. They help move waste more efficiently and green papaya juice helps to cleanse the colon naturally
