Few foods carry as much pregnancy folklore as dates. Almost every Malaysian mother has been told to eat them in the final weeks, usually with great confidence and no explanation.
The unusual thing is that in this case there really is published research. It's just smaller and more qualified than the way it gets repeated.
So here's the honest version.
Before anything else: this article is general information, not medical advice. Pregnancy nutrition is individual, and anything you add to your diet in the third trimester should be discussed with your doctor or midwife first — particularly if you have gestational diabetes.
What Dates Offer Nutritionally in Pregnancy
Set the labour question aside for a moment. As a food during pregnancy, dates bring several things that matter:
Folate — essential for healthy fetal development, particularly early in pregnancy. Dates contribute, though your prescribed supplement remains the primary source and shouldn't be replaced.
Iron — pregnancy substantially increases iron requirements, and iron-deficiency anaemia is common. Dates contribute plant-based iron, and pairing them with vitamin C improves absorption.
Fibre — around 6–7g per 100g. Constipation affects a large proportion of pregnancies, and dietary fibre is the first-line approach most doctors suggest.
Potassium and magnesium — both support fluid balance and normal muscle function.
Natural energy — fibre-buffered sugars release more gradually than sweets, which is useful during a period when energy levels are unpredictable.
None of this makes dates essential. It makes them a genuinely useful whole food in a diet that already includes plenty else.
The Labour Research: What Was Actually Found
This is the part everyone has heard about, so it's worth being precise.
The best-known study was published in the Journal of Obstetrics and Gynaecology in 2011 by Al-Kuran and colleagues in Jordan. Women ate six dates a day for the four weeks before their due date, and were compared with women who ate none.
The findings:
| Measure | Date group | Control group |
|---|---|---|
| Cervical dilatation on admission | 3.52 cm | 2.02 cm |
| Spontaneous labour | 96% | 79% |
| Needed prostin/oxytocin | 28% | 47% |
| Latent phase of first stage | 510 min | 906 min |
The authors concluded that eating dates in the last four weeks significantly reduced the need for induction and augmentation of labour, and produced a more favourable — but not statistically significant — delivery outcome.
Further studies since, including work in Saudi Arabia, have reported broadly similar directions of effect.
How Seriously Should You Take That?
Honestly? It's encouraging, and it's not proof.
What's genuinely notable: the findings point consistently in the same direction across more than one study, and the measured differences in cervical dilatation and induction rates were substantial rather than marginal.
What limits it:
- The studies are small — the best-known involved fewer than 100 women.
- Not every outcome reached statistical significance, including the delivery outcomes themselves.
- Participants knew what they were eating, so expectation effects can't be excluded.
- Findings have not translated into formal clinical guidelines.
A fair summary: eating dates in late pregnancy appears in published research to be associated with more favourable early labour progress. It is not a medical intervention, it won't guarantee anything about your birth, and it is no substitute for your antenatal care.
If your midwife or obstetrician is happy for you to eat dates, the evidence is reassuring enough to make it a reasonable thing to do. That's about as strong as the claim should be made.
The Cautions That Matter
Gestational diabetes. This is the important one. Dates are high in natural sugar, and while their glycemic index sits at a moderate ~50, that doesn't make them automatically suitable if you're managing gestational diabetes. Speak to your doctor before adding dates to your diet if you have GDM or are being monitored for it.
Portion size. Six dates a day was a study protocol, not a health recommendation. Six Medjool is roughly 400 calories. Six smaller dates is around half that. If you're going to follow the pattern, smaller varieties make far more sense.
Weight management in pregnancy. Dates are calorie-dense. Adding six a day on top of an existing diet is a meaningful increase.
Timing. The research specifically studied the final four weeks. Nothing in it suggests eating large quantities throughout pregnancy.
Everything else. Allergies are rare but possible. And as always — your doctor knows your pregnancy, we don't.
Which Dates to Choose
If you and your doctor decide dates are a good fit, smaller varieties are the more sensible choice — easier to portion and less sugar per piece:
- Ajwa — small, mild, easy to count. The variety most Malaysian mothers reach for.
- Safawi — soft, medium-sized, good value for daily eating.
- Mariami — chewy and affordable at volume.
- Rotab — very soft, easy to eat if you're dealing with nausea or a poor appetite.
Less suited: Medjool, simply because of size. One Medjool is roughly three small dates' worth of sugar, which makes portion control harder.

Practical Ways to Eat Them
- With yoghurt or milk — the protein slows sugar absorption
- Chopped into oats or porridge — good for breakfast when appetite is low
- With nuts — almonds or walnuts alongside; helps with satiety
- Blended into a smoothie — easy if nausea makes solid food difficult
- As a replacement for biscuits or sweets, rather than in addition
Frequently Asked Questions
How many dates a day during pregnancy? The research used six a day in the final four weeks. That's a study protocol, not a prescription — ask your doctor what's right for you, and factor in the size of the variety.
When should I start eating dates? The studies looked specifically at the last four weeks before the due date.
Do dates induce labour? No. The research suggests more favourable early labour progress and less need for medical induction — it does not show that dates start labour.
Are dates safe in early pregnancy? Dates are a normal food and are widely eaten throughout pregnancy. Discuss your overall diet with your doctor.
Can I eat dates with gestational diabetes? Ask your doctor. Dates are high in natural sugar, and GDM management is individual.
Do dates help with constipation in pregnancy? They're a good source of fibre, which supports regular digestion. Increase gradually and drink plenty of water.
Is there a religious basis for eating dates in pregnancy? Dates hold a valued place in Islamic tradition. For guidance on religious practice, please consult a qualified scholar.
