Understanding the Sugar Composition of Dried Prunes
Dried prunes are known for their digestive benefits and contain natural sugars, which are concentrated during the drying process. Prunes contain a mix of glucose, fructose, and sorbitol. This combination, along with high fiber, contributes to a relatively low glycemic index.
Fructose Levels in Prunes
A 100g serving of prunes contains around 12g of fructose. While this is a notable amount, prunes have a more balanced sugar profile compared to some other dried fruits like dates, raisins, and figs, which can have higher total sugar or fructose concentrations.
The Role of Fiber and Sorbitol
Prunes are rich in dietary fiber (about 7.1g per 100g). Soluble fiber slows sugar absorption, preventing rapid blood sugar spikes. Prunes also contain sorbitol, a sugar alcohol that is only partially absorbed, affecting their overall carbohydrate impact.
How Prunes Affect Blood Sugar
Prunes have a low glycemic index (GI) of 29. The fiber and sorbitol content contribute to this low GI by promoting a gradual release of sugar into the bloodstream. This can make prunes a suitable option in moderation for those monitoring blood sugar, including individuals with diabetes. However, portion control is still important due to their concentrated calories and sugar.
Prunes vs. Other Dried Fruits: A Sugar Comparison
The sugar content of prunes compares favorably to other dried fruits:
| Dried Fruit | Total Sugar (per 100g) | Fructose (per 100g) | Glycemic Index (GI) | Note on Sugar Profile |
|---|---|---|---|---|
| Prunes | ~38g | ~12g | 29 (Low) | Contains sorbitol and high fiber, moderating impact. |
| Raisins | ~59g | ~16g | 64 (Medium) | Higher total sugar and higher GI than prunes. |
| Dates | ~64-66g | ~7.7g (Medjool) | 42 (Low) | Extremely high in total sugar, but lower fructose percentage than raisins. |
| Dried Figs | ~48g | ~23g | 61 (Medium) | Higher fructose and GI compared to prunes. |

Incorporating Prunes into a Balanced Diet
A typical serving of four to five prunes provides nutrients without excessive sugar. Ways to enjoy prunes include snacking, adding to oatmeal, using in baking, incorporating into savory dishes, or blending into smoothies. Those sensitive to FODMAPs should start with small amounts to assess tolerance, as sorbitol and fiber can cause digestive issues in some individuals.
Conclusion: Fructose Content is Only Part of the Story
While dried prunes contain fructose, they also have fiber and sorbitol, resulting in a low glycemic index and steady energy release. Consumed in moderation, prunes are a good source of natural sugars, fiber, vitamins, and minerals that support digestive, bone, and heart health. Portion control is crucial due to their concentrated calories. Prunes are a beneficial addition to a balanced diet when consumed mindfully.
