Pineapple and Childbirth: Does it Really Work?

“Eat pineapple when you're close to giving birth.” You might have heard this advice before. It's particularly common in English-speaking pregnancy and parenting communities. Alongside spicy foods, raspberry leaf tea, and dates, it's known as a folk remedy to aid labor, with pineapple often getting special attention. This is due to the speculation that an enzyme called bromelain, found in pineapple, might influence cervical ripening. While evidence has been scarce, a recent study has brought this old wives' tale back into the spotlight.

Study Findings: Does Pineapple Shorten Labor?

Angie, a UK-based midwife, shared insights on her TikTok channel about the connection between late-term pineapple consumption and labor. The study she referenced was published in the journal Medicine in April of this year, analyzing data from 2,400 women who gave birth in Nigeria. Researchers compared cervical ripening, labor duration, and delivery methods between groups who consumed pineapple and those who didn't.

Positive Outcomes from Pineapple Consumption

The analysis revealed that women who consumed pineapple during their third trimester had a higher Bishop score, a measure of cervical readiness for labor, upon admission. This indicates their cervix was better prepared for childbirth. Additionally, labor lasted an average of 1.7 hours shorter, and the likelihood of a successful vaginal birth increased by approximately 1.8 times. Conversely, the rate of Cesarean sections was lower.

• Cervical Ripening: Higher in the pineapple consumption group
• Labor Duration: Shortened by an average of 1.7 hours
• Likelihood of Vaginal Birth: Increased by 1.8 times
• Cesarean Section Rate: Decreased

Connection to Newborn Health?

There were no significant differences observed in newborn health. There were no significant variations between the groups in terms of birth weight, Apgar score, or neonatal intensive care unit (NICU) admission rates. The researchers also noted a trend where higher pineapple consumption was associated with shorter labor times and a higher rate of vaginal births.

Precautions and Expert Opinions

However, this study was observational, not a randomized clinical trial, so it's not possible to definitively conclude that pineapple directly speeds up labor. Angie commented, “If you enjoy pineapple, it might be beneficial to eat it in late pregnancy,” but added, “More research is needed to conclusively prove its labor-inducing effects.”

Meanwhile, in Korea, there's a prevailing myth that consuming pineapple in early pregnancy increases the risk of miscarriage. This stems from the claim that bromelain can induce uterine contractions. However, to date, there is no confirmed evidence that consuming pineapple at typical dietary levels causes miscarriage or premature birth. Obstetrics and gynecology specialists explain that the amount of bromelain in pineapple flesh is not high and is mostly broken down during digestion.
