In the 19th chapter of the Koran, Mary is giving birth to Jesus. I didn’t even know Jesus was in the Koran. The things they don’t teach you in Hebrew school. It says, “And the pains of childbirth drove her to the trunk of a palm tree.”  She cries out, and she is answered by Gabriel, Archangel and, evidently, obstetrician—who knew? Shake the tree, he says, and “it will drop upon you ripe, fresh dates,” and you’ll be all better—no epidural necessary.

Do dates really help with labor and delivery? It would take a little over 2,000 years, but researchers finally decided to put it to the test. They had some “anecdotal evidence” that dates might be helping, but they wanted to know for sure “whether the addition of date fruit for the last few weeks of pregnancy would reduce the need for labor induction or augmentation”—that’s where you give drugs to induce uterine contractions, to initiate or accelerate labor. It’s “one of the most commonly-performed obstetrical procedures” in the U.S., dramatically increasing over the last few decades—from less than 10% of deliveries to now nearly a quarter. There are certainly legitimate medical indications, but are often done just for “convenience,” and not necessarily the convenience of the patient, but the provider may also have perverse “financial incentives” and other reasons to want to speed things along. Dates might not help with those factors, but might they help foster a normal spontaneous delivery? Let’s find out.

A prospective study: women eating six dates a day—that’s totally doable—during their last month of pregnancy versus no dates at all, and…”the women who consumed date fruit had significantly [better] cervical dilation,…significantly higher proportion of intact membranes.” That’s a good thing.  And: “Spontaneous labor occurred in 96% of those who consumed dates, compared with 79% women in the non-date” group, with significantly less drugs used, and the “labour was shorter,” as in about seven hours shorter overall. “It is [therefore] concluded that the consumption of date fruit in the last 4 weeks [of pregnancy] significantly reduced the need for induction and augmentation of labour…The results warrant a randomised controlled trial.”

Wait, what? The women weren’t randomized? They even talk about how it was hard to find women who would agree to not eat dates because it’s part of their cultural beliefs. So, you can totally imagine how there could be all sorts of differences between the women who ate dates, and those who agreed to go without, that could account for the findings. Maybe the date-eaters were more religious, or higher socioeconomic status, or who knows. Yeah, you can argue, what’s the downside? Might as well give dates a try. But that’s not good enough for me. I want to know if they actually work. But there had never been a randomized, controlled trial…until three years later.

“The effect of late-pregnancy consumption of date fruit on [so-called] cervical ripening” in first-time mothers. In the last few weeks of pregnancy hormonal changes cause the cervix, the opening to the uterus, to start to ripen, to soften, so that when the contractions start, it can more easily dilate open.

“At this stage, the cervix loses its integrated structure, and therefore, it becomes soft and dilated as soon as strong contractions begin.” Through a ripe cervix you can push a baby out with like 20 pounds of pressure per square inch, but if the cervix isn’t there yet, it can require more like 200 pounds of pressure. So, it goes without saying that “[c]ervical ripening before the onset of labor is …important” if you want a normal vaginal delivery. “The search for a safe, inexpensive, and easy method of [facilitating] cervical ripening is therefore of great significance.” So, let’s randomize a few hundred women starting at like the 37th week to eat about six dates a day—or not—until their first contraction.

Cervical ripening is rated with a Bishop score. Normally, a score of five or less “indicates an unfavorable cervix,” whereas eight or more and you’re good to go, and…the average Bishop score in the women randomized to the date group was significantly higher, closer to eight, whereas the date-free group was down at around five, and the cervix was more dilated in the date group. And hey, dates are healthy anyway, so maybe dates should be “recommended for pregnant women to help with cervical ripening, particularly in the last weeks” of their pregnancy.

Doctor's Note

What about the effects of dates on spontaneous delivery, premature delivery, labor time, and postpartum bleeding? All covered in my next video: Best Food for Labor and Delivery.

I have lots more pregnancy videos here.

What do you do with dates? Eat them, silly! But I also use them in recipes in my How Not to Die Cookbook (all my proceeds to charity) in the form of Date Syrup and a Balsamic Date Glaze.
