Some women claim that pineapple, spicy food, eggplant parmesan and licorice will induce labor, advises OBGYN North. However, there is little scientific evidence to confirm of deny any of these claims.
Many women claim that spicy food brings on labor, according to OBGYN North. However, spicy foods release capsasins, which interfere with the endorphins that reduce labor pain. Some claim eggplant parmesan brings on labor, but OBGYN North advises that the basil and oregano used in the dish are likely what starts labor. Both herbs are not to be consumed during pregnancy due to the potential risk of premature labor.
Pineapple is theorized to stimulate the production of prostaglandins, which ripen the cervix, explains OBGYN North. Similarly, a substance called glycyrrhizin in licorice potentially stimulates the production of prostaglandins. Eating large quantities of licorice may cause diarrhea, which in turn may cause intestinal contractions that may lead to uterine contractions.
