The Caloric Breakdown of Quince
Despite being a cousin to apples and pears, the quince (Cydonia oblonga) often flies under the radar. Its unique tartness and tough texture when raw mean it's almost always consumed after cooking. For those monitoring their intake, a raw quince is a low-calorie fruit, but preparations can drastically change its final nutritional value. A standard 100-gram serving of raw quince contains about 57 kilocalories (kcal). This low-energy density makes it an excellent choice for a healthy eating plan, provided you don't add excessive sugar during preparation.
In addition to its low-calorie count, quince is packed with a variety of nutrients. It is a good source of dietary fiber, which aids in digestion and helps promote a feeling of fullness. It also contains a moderate amount of vitamin C, essential for immune function, and copper, which plays a role in energy production.
Raw vs. Cooked Quince Calories
As mentioned, raw quince is typically too hard and astringent to eat and must be cooked to become palatable. When poached or baked without any added sweeteners, the caloric value remains low. For example, a poached quince warmed in its own syrup would retain its natural, low-calorie profile.
However, the calorie count can increase dramatically when quince is cooked with sugar, a common practice to balance its tartness. Traditional preparations like quince paste (membrillo) or quince jam, which require significant amounts of added sugar, are much more calorie-dense. While cooking can lead to a slight loss of some heat-sensitive nutrients like vitamin C, it can also enhance the availability of certain antioxidants.
Nutritional Comparison: Quince, Apples, and Pears
To put quince's nutritional value in perspective, here is a comparison with its more popular relatives, the apple and the pear, per 100g serving.
| Nutrient | Quince (approx.) | Apple (approx.) | Pear (approx.) |
|---|---|---|---|
| Calories | 57 kcal | 52 kcal | 57 kcal |
| Carbohydrates | 15.3 g | 13.8 g | 15.2 g |
| Dietary Fiber | 1.9 g | 2.4 g | 3.1 g |
| Vitamin C | 17% DV | 14% DV | 7% DV |
| Potassium | 7% DV | 3% DV | 4% DV |
| Pectin Content | High | Moderate | Moderate |
Quince stands out for its high potassium and pectin content when compared to apples. Pectin, a type of soluble fiber, is what gives quince-based jellies and jams their firm texture and offers digestive benefits.
Beyond Calories: The Health Benefits of Quince
Quince is more than just a low-calorie fruit; it is also a source of compounds that contribute to overall health. Many of the benefits are associated with its rich antioxidant content.
- Packed with antioxidants: Quince is rich in potent antioxidants, such as quercetin and kaempferol, which help reduce metabolic stress and protect cells from damage by free radicals.
- Supports digestive health: The fruit's high fiber and pectin content promote a healthy digestive system. Quince extract has also shown potential in animal studies to protect against gut tissue damage associated with inflammatory bowel diseases.
- May aid in immune function: With a good amount of vitamin C, quince supports a strong immune system. Test-tube studies also suggest it may possess antibacterial properties against certain harmful bacteria.
- Provides potential relief for acid reflux: Some studies have indicated that quince syrup may be as effective as traditional medications in managing the symptoms of acid reflux.
- High mineral content: Compared to related fruits like apples, quince contains higher amounts of important minerals like potassium and phosphorus.

How to Enjoy Quince for Health
To keep your quince dishes low in calories, focus on preparations that minimize or eliminate added sugar. Try poaching slices of quince in water with spices like cinnamon or star anise for a flavorful, low-sugar treat. This tender, pink-hued fruit can then be used to top oatmeal or yogurt. Alternatively, you can bake quince with a sprinkle of natural, low-calorie sweetener. If you decide to make jam or paste, be mindful of the sugar content and consider it an occasional indulgence rather than a daily staple.
Conclusion
In summary, how many calories are in a quince is primarily determined by how it's prepared. Raw quince is a low-calorie, nutrient-rich fruit with about 57 kcal per 100g. Its full nutritional value, including powerful antioxidants and high fiber, makes it a healthy addition to your diet. While processed versions like jams and pastes come with a high calorie count due to added sugar, simple cooking methods like poaching or baking can help you enjoy this unique fruit while maintaining a low-calorie intake.
