Many cultures firmly believe that eating papayas during pregnancy is a strict no, no. Papaya intake apparently brings on labour early. This is partially true. Unripe and semi-ripe papayas only are rich in latex which is known to trigger uterine contractions. There are also heating in nature and are better avoided during the third and final trimester Pineapples are rich in bromelain which can cause the softening of the cervix leading to early labour. However, for that to happen, a pregnant woman has to drink pineapple juice in excessive quantities that will first lead to diarrhoea.
12:49 here - I think this is probably what my mom was talking about in regards to Papaya!
