Papayas grow in tropical climates and are also known as papaws or pawpaws. Their sweet taste, vibrant color, and a wide variety of health benefits they provide make them a popular fruit. The nutrients found in papaya are thought to have a range of health benefits. They may help protect against a number of health conditions. Papaya leaves have a component called papain, which can be toxic for your baby if you are pregnant. It can even lead to birth defects. Not much is known about the side effects of papaya during breastfeeding, thus, it's best to avoid having papaya during and after pregnancy for some time.
