No, dates sit in the low-to-moderate glycemic range; glycemic load from dates depends on portion size and variety.
Dates taste sweet, yet most lab-tested varieties land near the lower end of the glycemic index (GI). Clinical trials that fed equal carbohydrate portions from several cultivars reported GI values in the mid-40s to mid-50s on the glucose scale. In day-to-day eating, two things decide the real impact: how much you eat and what you pair with them.

Glycemic Index, Glycemic Load, And Why Both Matter
GI ranks how fast a food raises blood sugar compared with pure glucose. The University of Sydney’s GI group uses these cutoffs: low ≤55, medium 56–69, high ≥70. (GI categories) GL goes a step further: it multiplies a food’s GI by the grams of available carbohydrate in your serving and divides by 100. (GL formula)
Early Answer, Then The Details
Across controlled trials, date fruit usually lands in the low range. One peer-reviewed trial tested five cultivars and found GI values between 46 and 55 in people without diabetes, and 43 to 53 in people with type 2 diabetes who were diet/Metformin managed. The same study reported no notable difference between groups. (Nutrition Journal trial)
Table: Date Varieties And Reported GI (Glucose Scale)
Measured with equal available carbohydrate servings (50 g) as used in GI testing protocols. Values from a controlled clinical study; lab protocols and ripeness can shift results slightly.
| Variety | Reported GI | Study Source |
|---|---|---|
| Fara’d | 54.0 ± 6.1 | Alkaabi et al. |
| Lulu | 53.5 ± 8.6 | Alkaabi et al. |
| Bo Ma’an | 46.3 ± 7.1 | Alkaabi et al. |
| Dabbas | 49.1 ± 3.6 | Alkaabi et al. |
| Khalas | 55.1 ± 7.7 | Alkaabi et al. |
Are Date Fruits High On The Glycemic Scale? A Practical View
The GI readings above sit at the boundary of low, with most varieties below the 55 cutoff. That means a single portion eaten with a meal tends to raise glucose more gently than starchier snacks. That said, GL climbs fast when portions jump, because dates pack a lot of carbohydrate into small bites.
GI Vs. GL: How The Same Snack Can Feel Different
GI is a lab number based on 50 g of available carbohydrate from a single food. Few people eat that much date sugar at once. GL scales the lab number to your plate. Here’s the simple math you can use anywhere:
- GL = (GI × grams of available carbohydrate in your serving) ÷ 100.
- With a GI near 50, a 20 g carbohydrate serving has GL ≈ 10 (low); a 40 g carbohydrate serving has GL ≈ 20 (high).
These cutoffs and the formula are described by the Linus Pauling Institute and the Sydney GI team. (GL definition · GI bands)
Portion Reality: What’s In A Typical Date Snack?
Nutrient databases list one large Medjool date at about 18 g carbohydrate, while 100 g of dried dates carries about 75 g carbohydrate. Two large pieces give a fast 36 g. A small handful of chopped pieces can creep past that if you’re not measuring. Numbers vary by variety and moisture level, yet those ballparks line up with standard listings used by dietitians and trackers.
What Drives Variation Between Batches
- Ripeness stage: later stages tend to have less water and more available sugars.
- Variety: fiber and sugar profiles differ by cultivar.
- Pairings: protein, fat, and viscous fiber slow gastric emptying.
How To Eat Dates With Steady Energy
Pick A Portion You Can Repeat
Choose a go-to portion that fits your day and stick with it. Two large pieces as a snack? Great. Keep it consistent across weeks so you can judge your own response.
Pair For Balance
Blend chopped dates into plain yogurt or oatmeal. Wrap a pit-removed piece with a walnut. Spread peanut butter on half a date and chew slowly. Those small adds blunt the curve for many people.
Time It Right
Place sweeter snacks around training or long walks. Muscle uptake after movement can make the rise feel smoother.
Research Snapshot: Why Dates Score Low To Mid
The Nutrition Journal trial above used standardized methods for GI testing. Each subject ate test portions of dates that supplied 50 g of available carbohydrate, and capillary glucose was measured over two hours. Reported GI values fell in a tight band for all five cultivars. The authors also noted similar values in participants with and without type 2 diabetes who were stable on diet or Metformin. (Study details)
Table: Typical Portions And Estimated GL
GL uses a working GI of 50 for dates (near the pooled mean in published tables). “Available carbs” reflect common listings for Medjool dates and dried date pieces. Your numbers may shift with variety and moisture.
| Portion | Available Carbs (g) | Estimated GL |
|---|---|---|
| 1 large Medjool date | ~18 | ~9 (low) |
| 2 large Medjool dates | ~36 | ~18 (medium) |
| 40 g chopped dates | ~30 | ~15 (medium) |
| 60 g chopped dates | ~45 | ~23 (high) |
| 100 g dried dates | ~75 | ~38 (high) |
Reading Labels And Database Entries
Portion lines on labels often list “carbohydrate” and “fiber.” GL uses available carbohydrate, so subtract fiber first. If a label shows 24 g total carbohydrate and 3 g fiber, the available amount is 21 g. With a GI near 50, GL sits near 10. That’s an easy way to sanity-check your bowl when you mix dates into cereal or yogurt.
When A Low GI Still Feels Like A Spike
Individual response varies. Sleep, stress, time of day, and prior meals can dial the curve up or down. A snack that reads mild on paper can feel sharper after a long gap without food. If you wear a CGM, track three repeats of the same portion at the same time of day and look for a pattern instead of chasing one off day.
Balanced Uses That Work Well
Everyday Add-Ins
- Two chopped dates folded into Greek yogurt with cinnamon.

- Chicken salad with a few thin slices for sweet contrast.
Pre-Workout Bites
- One large Medjool stuffed with peanut butter and a pinch of salt.
- Two small Deglet Noor with a handful of almonds.
FAQ-Free Clarity: Quick Checks Before You Eat
- What’s the GI band? Mostly low, often near 50 on the glucose scale. (Cutoffs)
- What’s my GL? Multiply GI by grams of available carbohydrate in your serving and divide by 100. (Formula)
- When does it feel “high”? Large portions or eating dates solo on an empty stomach.
Method Notes, Sources, And Safe Use
GI numbers here come from controlled human trials and the Sydney group’s reference bands. The Nutrition Journal study tested five cultivars and reported GI values between 46 and 55 in people without diabetes, and 43 to 53 in people with type 2 diabetes. (Trial) GI category bands and test methods come from the University of Sydney’s GI team. (GI bands) GL definition and cutoffs appear in the Linus Pauling Institute’s overview. (GL overview)
The Takeaway You Can Use Tonight
Dates aren’t sugar bombs by default. Most test as low-GI, and they fit well when portions stay modest and pairings add protein, fat, or fiber. Keep your usual serving, fold them into balanced meals, and let GL guide the size. That’s how you enjoy the flavor while keeping numbers steady.
