Eating pineapple in late pregnancy to catalyze labor is an unscientific statement, pineapple does not have the effect of catalyzing labor, and it is not currently recommended to catalyze labor on your own in late pregnancy to avoid danger. Pineapple is a common fruit, rich in vitamins, trace elements and dietary fiber, pregnant women eat pineapple in moderation to meet certain nutritional needs, is conducive to the growth and development of the fetus, but pineapple does not have the effect of inducing labor. And ordinary food does not have the effect of inducing labor. The occurrence of labor is mainly related to the changes of maternal hormones. Under normal circumstances, when the fetus matures, it will stimulate the mother to secrete prostaglandins, contractions and so on, thus promoting the labor to start. When labor begins, contractions will occur and the pressure in the uterine cavity will increase significantly, making it easy for complications such as intrauterine hypoxia and slowing of the fetal heart rate to occur. It is important to carry out the labor under the guidance of a hospital midwife, and to avoid inducing labor on one’s own. If there is still no obvious labor performance for a long time after the due date, it is recommended to go to the hospital for examination in time, and if necessary, induce labor under the guidance of a professional doctor to ensure the health of the pregnant woman and the fetus in the process of labor and delivery.
