Date benefits: 48 studies on childbirth — and the authors called the evidence quality unacceptable

Key benefits

1. 01Early research

   A long list of positive findings, and authors who called the evidence unacceptable

   2024, BMC Pregnancy and Childbirth. A systematic review and dose-response meta-analysis, registered on PROSPERO.

   Methods.

   • Eight databases searched from inception to 30 April 2023
   • Randomised and non-randomised controlled trials in any language, conducted in the peripartum period (third trimester, late pregnancy, labour or postpartum)
   • Standard care plus oral dates versus standard care alone or combined with other alternatives
   • Assessed with the Cochrane Risk of Bias tools and GRADE
   • 2,460 records screened, 48 studies (55 publications) included

   What was reported.

   Period	Reported findings
   Late pregnancy	Shorter gestation and labour (except second stage), less need for induction, faster spontaneous delivery, higher cervical dilatation on admission and Bishop score, more spontaneous vaginal deliveries
   During labour	Shorter labour (except third stage), greater cervical dilatation two hours after the intervention
   Postpartum	More breast milk, less post-delivery haemorrhage
   Third trimester	Higher maternal haemoglobin
   Fetal, neonatal, infant	Data insufficient for meta-analysis; most outcomes not substantially different between groups

   And the same abstract states:

   • "The overall evidence quality was also unacceptable"
   • "RoB was high in most studies"
   • "The intervention's safety was recorded only in four trials"
   • Conclusion: "More well-designed investigations are required to robustly support consuming dates during peripartum as effective and safe integrated care"

   How to read this.

   First, the number of findings is not the strength of the evidence. That many outcomes reached significance across 48 studies is a different matter from whether those 48 studies can be trusted. The authors themselves denied the second.

   Second, non-randomised trials are included. Without randomisation, allocation itself can be entangled with the outcome — if the mothers who ate dates were better prepared overall, that difference shows up as effect.

   Third, safety data are almost absent. Only four of the 48 recorded safety. To recommend something in pregnancy, safety comes before efficacy, and that data is missing.

   Fourth, the outcomes for the baby had too little data. Fetal, neonatal and infant outcomes could not be pooled, and most of what was reported showed no substantial difference between groups.

   Fifth, count the sugar alongside. A common dose in these trials is around six dates a day — roughly 144 g, carrying about 96 g of sugar. That is not an amount to recommend unexamined to a mother with, or at risk of, gestational diabetes.

   This site's honest conclusion:

   • There may be something here. Multiple studies point the same way
   • But the authors themselves rated the evidence "unacceptable". This site does not rewrite that rating
   • Any dietary change in pregnancy belongs with your care team, especially with gestational diabetes
   • The grade here is "early research"

2. 02Nutrition data

   66.5 g of sugar per 100 g — that is 16 g in a single date

   Per 100 g of Medjool dates:

   • 277 kcal, sugar 66.5 g, carbohydrate 75.0 g
   • Fibre 6.7 g
   • Potassium 696 mg — 15% of the requirement
   • Magnesium 54 mg, calcium 64 mg, copper 0.362 mg
   • Vitamin B6 0.249 mg, protein 1.81 g
   • Fat 0.15 g, sodium 1 mg

   66.5 g of it is sugar. That is what this fruit is: drying removed the water and concentrated the sugar.

   Per date (24 g):

   	100 g	One date (24 g)	Three dates (72 g)
   Energy	277 kcal	66 kcal	199 kcal
   Sugar	66.5 g	16.0 g	47.9 g
   Fibre	6.7 g	1.6 g	4.8 g
   Potassium	696 mg	167 mg	501 mg

   One date carries 16 g of sugar. The WHO recommends free sugars below 5% of energy — under 25 g on 2,000 kcal. Two dates reach that line.

   But an important qualification. The WHO's definition of free sugars covers added sugars and those in honey, syrups and fruit juice, and sugars present within whole or dried fruit are not counted as free sugars. So dates' sugar cannot be counted identically to table sugar.

   That is not permission to eat freely. Dried fruit shrinks in volume and is easy to overeat, and three dates is already 199 kcal.

   The 6.7 g of fibre is high — 1.6 g per date. Fibre arriving with the sugar is what distinguishes this from table sugar, and it changes the rate of absorption.

   696 mg of potassium is also high, close to twice a banana's 358 mg. But if you restrict potassium for kidney disease, that is a caution rather than a benefit.

   Varieties differ.

   • Medjool — large and soft. The table above
   • Deglet Noor — smaller, firmer, slightly less sugar

   The white bloom on the surface is not mould. It is sugar crystallising out, and it appears with storage.

   Store them sealed and cool, refrigerated for longer keeping.

3. 03Not established

   "It's natural sugar, so it's fine" — with diabetes that is a different conversation

   This entry sorts through a common misunderstanding.

   Dates are often recommended as a natural sweetener to replace sugar, and blending them into desserts in place of sugar is a common technique.

   Part of that is right.

   • Fibre comes with it — 1.6 g per date, against zero in table sugar
   • There are minerals: potassium, magnesium, copper
   • It is sugar within fruit rather than added sugar, so it does not fall under the WHO's free-sugar figure in the same way

   But there are parts you cannot skip.

   First, sugar is sugar. Dates' sugars are mainly glucose and fructose — the same sugars table sugar breaks down into. Their effect on blood glucose does not disappear.

   Second, the low-GI claim is conditional. Reported glycaemic index values for dates vary widely by variety and ripeness. And GI is defined on 50 g of carbohydrate, which is not the one or two dates you actually eat. A low GI is also not permission to eat more.

   Third, with diabetes the situation changes. Sixteen grams of sugar per date. If you are managing blood glucose, that number belongs in your count. "It's natural" does not exempt it.

   Fourth, gestational diabetes especially. The childbirth studies above used around six dates a day, reaching about 96 g of sugar. With gestational diabetes or at risk of it, do not copy that dose on your own. Speak to your care team.

   Fifth, dried fruit is easy to overeat. Fresh fruit creates fullness through water and volume; dried fruit has lost that brake. Three dates is 199 kcal, and eaten absent-mindedly it goes past that fast.

   The honest conclusion: dates are a better sweetener than sugar. But they are not "not sugar". And with diabetes or gestational diabetes, the word natural exempts nothing.
