A Nutrient-Dense Fruit
Quince is an ancient fruit with a distinctively tart and aromatic profile that becomes sweet and flavorful when cooked. While its more common relatives, the apple and pear, steal the spotlight, quince holds its own with a dense nutritional makeup. The fruit is particularly noted for its high content of dietary fiber, vitamin C, and a rich array of antioxidants. This combination of nutrients provides a range of health benefits, from improving digestion to strengthening the immune system.
The Top Nutrients Found in Quince
Dietary Fiber, Including Pectin
One of the most impressive components of quince is its high dietary fiber content. For example, a 92-gram serving provides a significant amount of fiber, which is crucial for digestive health. The fiber in quince is largely composed of pectin, a soluble fiber that forms a gel-like substance in water.
- Digestive Regulation: Fiber promotes regular bowel movements and can help prevent constipation by adding bulk to the stool. Pectin, in particular, can soothe the intestinal wall and aids in better digestion.
- Heart Health: Soluble fibers like pectin can help lower LDL ('bad') cholesterol levels by binding to fats in the intestine, which then limits their absorption. This contributes to overall cardiovascular protection.
- Weight Management: The high fiber content helps you feel full for longer, which can assist with weight control by reducing overall calorie intake.
Vitamin C and Antioxidants
Quince is a moderate but reliable source of vitamin C, an essential nutrient for immune function and overall health. In addition, the fruit contains a rich supply of powerful antioxidants.
- Immune System Support: Vitamin C is a powerful antioxidant that helps boost the immune system and fights off infections. A single quince can contribute notably to your daily needs.
- Cellular Protection: Quince is rich in potent antioxidants, including flavonols like quercetin and kaempferol, and tannins. These compounds reduce oxidative stress, lower inflammation, and protect cells from damage caused by free radicals.
- Anti-Inflammatory Properties: The antioxidants in quince can help reduce inflammation throughout the body, which may offer benefits for conditions like arthritis.
Other Notable Vitamins and Minerals
Beyond fiber and vitamin C, quince contains a variety of other important micronutrients:
- Copper: Quince is a good source of copper, which plays a role in energy production, iron metabolism, and supporting a healthy nervous system.
- Potassium: This mineral is important for maintaining healthy blood pressure levels and supporting heart function. A single quince provides a modest amount of potassium.
- Iron: Quince offers some iron, a mineral essential for oxygen transport in the blood. The vitamin C content in the fruit also helps the body absorb this iron more effectively.
Nutritional Comparison: Quince vs. Apple (per 100g)
To better understand quince's nutritional strengths, here is a comparison with its well-known relative, the apple, based on general nutritional data.
| Nutrient | Raw Quince (per 100g) | Raw Apple (per 100g) | What This Means |
|---|---|---|---|
| Energy | Approx. 57 kcal | Approx. 52 kcal | Similar low-calorie profile. |
| Protein | 0.4 g | 0.3 g | Very low protein in both. |
| Carbohydrates | 15.3 g | 13.8 g | Quince has slightly more carbs. |
| Dietary Fiber | 1.9 g | 2.4 g | Apples generally have a bit more fiber. |
| Vitamin C | 15 mg (17% DV) | 4.6 mg (5% DV) | Quince is notably higher in Vitamin C. |
| Potassium | 197 mg (7% DV) | 107 mg (3% DV) | Quince offers significantly more potassium. |
| Antioxidants | Rich in flavonols & tannins | Rich in quercetin & catechins | Both are good sources of antioxidants. |
Health Benefits Beyond Basic Nutrition
Because quince is high in several beneficial compounds, it has been used in traditional medicine for centuries. Some of its potential health benefits, supported by modern research, include:
- Soothing Digestive Issues: Compounds in quince, including tannins and pectin, have a protective effect on gut tissue and can help relieve symptoms of inflammatory bowel diseases (IBD) and stomach ulcers.
- Managing Acid Reflux: Studies indicate that quince syrup can be as effective as traditional medications in managing symptoms of gastroesophageal reflux disease (GERD).
- Relieving Nausea: Research has shown that quince syrup can significantly reduce pregnancy-induced nausea and vomiting.
- Combating Allergies: Some compounds in quince may help suppress allergic reactions, and some commercial remedies use quince extract for mild symptoms like rhinitis.
- Antibacterial Action: Test-tube studies suggest that quince has antibacterial properties that can help prevent the overgrowth of certain harmful bacteria, such as E. coli.
How to Eat Quince to Maximize Its Benefits
Raw quince is typically tough, astringent, and unpalatable. Cooking not only makes it edible but can also make some nutrients, like antioxidants and fiber, more bioavailable. It also releases the fruit's fragrant aroma and changes its color to a lovely red or pink.
Common Preparations:
- Jams and Jellies: Quince is famously used to make jams and jellies, thanks to its high pectin content.
- Poached: Simmering quince in water with a bit of sugar and spices like cinnamon or vanilla makes a delicious topping for yogurt or oatmeal.
- Baked: It can be baked like an apple or added to pies and tarts.
- Savory Dishes: Quince pairs well with savory dishes, especially roasted meats like pork.

Conclusion
So, what is quince high in? The answer is a potent combination of dietary fiber, vitamin C, and health-protective antioxidants. While not a typical raw snack, its versatility in cooked form makes it an excellent and nutrient-dense addition to a balanced diet. From supporting digestive and immune health to its antioxidant benefits, quince offers a sweet, tangy, and surprisingly powerful way to boost your nutritional intake. Whether poached, baked, or made into a delicious jelly, this ancient fruit proves its worth far beyond its unique appearance.
