Papaya is a tropical fruit originally from Mexico belonging to the melon family. It's famous for a special enzyme called "papain" which aids digestion and the breakdown of protein. In fact, traditional island peoples would always pair meat and fish dishes with papaya to capitalise on the extra enzymes and enhance digestion. Papaya is also high in vitamin C, beta-carotene, zeaxanthin and other minerals, making it an anti-aging, disease-preventing superstar.
