Unripe Papaya

In addition to potassium and magnesium, papaya is a great source of vitamins C, A, and E, which are potent antioxidants that support the health of the immune systems.

Unripe papayas, on the other hand, should be avoided by pregnant women in their first trimester as they contain a form of latex that can cause uterine contractions and early labor. Papain, one of the proteolytic enzymes found in papayas, is used in marinades to tenderize meat. This enzyme has the ability to mimic prostaglandin in your body and trigger labor. Additionally, papain has the ability to weaken the membrane supporting the fetus. Ripe papayas don't have papain and latex too. Other fruits that are high in vitamin A and C include oranges, mangoes, lemons, apples, and berries; bananas, avocados, and apricots are excellent choices for potassium.
