Date paste has become one of the signature ingredients in so-called “natural” energy bars. It is found in many organic, vegan, or artisanal recipes, often promoted as a healthier alternative to glucose syrups or refined sugars.
But behind this natural image lies a real performance question:
Is it really suitable for all sports? Is it ideal for a marathon, trail running, or an intense cycling session? Does it affect digestion or blood sugar?
To answer objectively, its nutritional profile, physiological behavior during exercise, and impact on digestion must all be analyzed.
What is date paste?
Date paste is made from whole, pitted dates, simply ground until they achieve a smooth, sticky texture. Unlike syrups, it retains the entire fruit: natural sugars, fiber, minerals, and antioxidant compounds.
Nutritionally, it consists primarily of carbohydrates, which account for approximately two-thirds of its weight. These carbohydrates consist of a natural mixture of glucose and fructose. This combination is of interest in sports because the two sugars use different intestinal transporters, which can improve absorption when exercise lasts a long time.
It also contains dietary fiber. This plays a beneficial role in the daily diet, but its presence can alter the rate of digestion during exercise.
Why add date paste to energy bars?
The appeal of date paste is not only nutritional. It is also technological.
First, it serves as a natural binder. Its sticky texture allows oat flakes, dried fruit, or plant proteins to be combined without using industrial texturizing agents. This makes it possible to formulate bars with a shorter, more understandable ingredient list.
Second, it supports strong marketing positioning: “sweetened only with fruit” or “100% natural.” In a market where transparency has become essential, this argument is powerful.
Finally, its naturally sweet, caramelized flavor enhances the bars’ sensory appeal (palatability), particularly during long efforts when taste enjoyment matters as much as energy intake. I’ve always said that when the body gives out, the mind takes over and helps you reach the finish line.
What science says about carbohydrates, dates, and performance
The latest scientific recommendations on sports nutrition indicate that:
-
For exercise lasting more than 2h30, the optimal carbohydrate intake is between 60 and 90g of carbohydrates per hour.
-
The combination of glucose and fructose makes it possible to increase carbohydrate oxidation to 1.75g/minute, compared with 0.8-1.1g/minute with glucose alone.
-
An excessively high fiber intake during exercise can slow gastric emptying and increase the risk of digestive discomfort.
Date paste naturally contains between 70 and 80% carbohydrates, including a significant proportion of glucose and fructose. This makes it an interesting energy source for replenishing glycogen stores during exercise. Many athletes consume fresh or dried dates in the same way as dried apricots.
Is date paste good for sports performance?
The answer depends greatly on the context of the effort.
During long-duration endurance efforts at moderate intensity, such as long-distance trail running, ultra-trail, long-distance cycling, or fitness hiking, date paste can be a suitable option. Its energy supply is relatively gradual, its texture is filling, and its naturalness is appreciated when the effort lasts several hours.
However, during high-intensity efforts such as a marathon at a sustained pace, a short-distance triathlon, or competitions with frequent surges such as Hyrox, the presence of fiber can slow gastric emptying. This can cause a feeling of heaviness or digestive discomfort in some sensitive athletes. In any case, it is almost impossible to chew during this type of event, so energy bars are not as suitable as gels or energy compotes.
In other words, date paste is neither “good” nor “bad”: it is suited to certain types of exertion and less suited to others.
What is the glycemic index of date paste?
The glycemic index of dates varies depending on the variety and degree of ripeness. It generally falls between low and moderate (GI 45-55). This means that blood sugar does not rise as abruptly as with pure glucose, but neither does it rise very slowly.
For an athlete, this means energy that is not as instantaneous as that of a energy gel rich in glucose, but that remains sufficiently fast-acting to support continuous effort. The presence of fiber also helps moderate the glycemic response.
Is date paste easy to digest during a marathon?
Digestibility depends on individual tolerance and running intensity. During a marathon run at a relatively high intensity, blood flow is diverted to the muscles, making the digestive system more sensitive. The fiber in date paste can then slow digestion and increase the risk of discomfort.
At a more moderate pace, tolerance is generally better. Many athletes use date-based bars during training without any problems, but prefer faster carbohydrate sources during competition.
It is always advisable to test your nutrition strategy during training weeks to determine which products and quantities are suitable. This is what is currently known as gut training, or stomach training.
Do date paste bars cause weight gain?
This question comes up often, particularly outside the context of sports.
Date paste remains a concentrated source of carbohydrates. It is energy-dense. However, as part of regular physical activity, these carbohydrates are used as muscle fuel and help replenish glycogen stores.
Therefore, it is not the ingredient itself that determines weight gain, but the overall balance between energy intake and expenditure.
Date paste or glucose syrup: which is the better option?
Glucose syrup is absorbed more quickly and contains no fiber. It is therefore particularly suitable for phases of very intense effort or moments when almost immediate energy is needed.
Date paste provides slightly more progressive energy, a denser texture, and a more natural image. It is better suited to long, steady efforts.
| Criterion | Date paste | Glucose syrup | Maltodextrin |
|---|---|---|---|
| Absorption rate | Progressive | Very fast-acting | Progressive to fast-acting |
| Presence of fiber | Yes | No | No |
| Digestive impact at high intensity | Moderate to high | Low | Low |
| Naturalness | High (whole fruit) | Low (refined sugar) | Low (processed) |
| Recommended effort | Long endurance, moderate intensity | Short, intense effort | Long, steady effort |
| Example format | Energy bar | Energy gel | Gel / sports drink |
The choice between the two therefore depends on the nutrition strategy, the type of effort, and the product positioning.
Should you choose an energy bar with or without date paste?
The choice should be guided by three criteria: exercise intensity, duration, and personal digestive tolerance.
For an ultra-trail or a long cycling session, a bar containing date paste may be relevant thanks to its natural profile and gradual energy release.
For a fast marathon or a short triathlon, a bar formulated without date paste, with an optimized carbohydrate blend and little fiber, may be more comfortable and deliver better performance.

FAQ - Frequently asked questions about date paste in sports nutrition
Is date paste better than white sugar?
It is less refined and retains micronutrients, but remains primarily a source of carbohydrates.
Can you make a homemade energy bar with date paste?
Yes, it is even the most commonly used ingredient in homemade recipes because of its natural binding properties.
Do dates provide energy quickly?
Yes, thanks to the glucose and fructose, but not as quickly as a gel made with pure glucose.
Is it suitable for athletes with sensitive stomachs?
It depends on the individual profile. Fiber can be an advantage in everyday life but sometimes a drawback at high intensity.
