Dates are very sweet, so it surprises many people that studies have measured their glycemic index in the low range. That does not make dates a free food for blood sugar. The amount you eat matters as much as the index. This article explains the research and how to use it. If you have diabetes, please talk to your doctor or dietitian before changing what you eat.
What the glycemic index measures
The glycemic index, or GI, ranks carbohydrate foods by how quickly they raise blood glucose compared with pure glucose, which is set at 100. Foods at 55 or below are classed as low, 56 to 69 as medium and 70 or above as high.
What research found for dates
The most cited study was published in Nutrition Journal in 2011. Researchers in the UAE tested five date varieties in 13 healthy volunteers and 10 people with type 2 diabetes. The average GI values ranged from about 46 to 55 in the healthy group and about 44 to 53 in the group with diabetes. The authors classed all five as low GI and reported that eating them did not cause significant rises in blood glucose after the meal in the participants with diabetes.
A later review and meta-analysis concluded that dates appeared beneficial for glycemic control in people with diabetes, while warning that the number of studies was small and the results varied.
Three reasons to read these results carefully
The studies are small. Twenty-three people is a starting point, not a final answer.
The varieties tested were specific. The 2011 study used five varieties common in the UAE, including Khalas. It did not test Ajwa, Sukkari or Medjool, and GI can differ by variety and ripeness.
People respond differently. Two people can eat the same food and see different glucose readings.
Why portion size matters: glycemic load
GI tells you how fast a carbohydrate acts. Glycemic load combines that with how much carbohydrate you actually eat. One pitted Medjool date contains about 18 g of carbohydrate, according to USDA data. If its GI is around 50, the glycemic load of a single date is about 9, which is in the low range. Four dates would be about 36, which is high.
The lesson is simple. One or two dates is a modest carbohydrate serving. A handful is not.
Practical tips for steadier blood sugar
- Keep the portion small. One or two Medjool dates, or two or three smaller dates, at a time.
- Pair dates with protein or fat. Nuts, nut butter, cheese or plain yogurt slow digestion.
- Eat them with a meal instead of alone on an empty stomach if you are sensitive.
- Count the carbohydrate. If you count carbs, a Medjool date is roughly 18 g.
- Choose smaller varieties such as Ajwa if you want a smaller serving per date.
- Check your own response. If you monitor your glucose, test after eating dates to see how you react.
If you have diabetes
The research is encouraging but not strong enough to give general permission. Dates are a concentrated source of carbohydrate, and medication, activity and the rest of your meal all affect the result. Agree a portion with your doctor or dietitian and include it in your meal plan. Dates are a food, not a treatment for diabetes.
Are dates better than sugar?
For sweetening, dates have an advantage over table sugar because they come with fiber, potassium and other nutrients. They still raise blood glucose and still contain calories. See dates as a natural alternative to refined sugar.
Smaller dates for smaller portions
If you prefer a milder, smaller date, look at Ajwa or Mabroom from Madinah. All Tamooriya dates are plain, with no added sugar. Browse the collection.

Frequently Asked Questions
What is the glycemic index of dates?
In a 2011 clinical study of five varieties, average GI values ranged from about 46 to 55, which is classed as low.
Can people with diabetes eat dates?
Some can include small portions in a meal plan, but this is an individual decision to make with a doctor or dietitian.
Do dates spike blood sugar?
Dates raise blood glucose because they are high in carbohydrate. In small portions the rise is moderate for most people. Large portions cause a larger rise.
Which dates have the lowest glycemic index?
There is not enough research to rank varieties reliably. Portion size is the more useful thing to control.
