Quince Fruit Benefits: 8 Science-Based Health Benefits and Uses

Quince (Cydonia oblonga) is an extraordinary ancient fruit that has been treasured for thousands of years across Mediterranean and Asian cultures. Despite being less common in modern Western diets, this golden-yellow fruit is making a comeback as researchers uncover its impressive health benefits.

Related to apples and pears, quinces have been used in traditional medicine systems for centuries to treat various ailments. Today, scientific research is beginning to validate many of these traditional uses, revealing that quinces are packed with beneficial compounds that support overall health.

In this comprehensive guide, we’ll explore eight evidence-based health benefits of quince fruit and provide practical tips on how to prepare and enjoy this unique superfruit.

What Is Quince Fruit?

Quince is a pome fruit that grows on small deciduous trees. Native to Southwest Asia, Turkey, and Iran, quinces have been cultivated for over 4,000 years. The fruit resembles a cross between an apple and a pear, with a bumpy, golden-yellow skin when ripe.

Unlike most fruits, quinces are generally too hard and astringent to eat raw. However, when cooked, they transform into a sweet, aromatic delicacy with a beautiful pink hue. The fruit has a distinctive floral fragrance that can perfume an entire room.

Historically, quinces symbolized love and fertility in ancient Greek and Roman cultures and were often presented as wedding gifts. Today, they’re primarily used in jams, jellies, preserves, and desserts throughout Europe and the Middle East.

8 Evidence-Based Health Benefits of Quince

1. Powerful Antioxidant Properties

One of the most significant benefits of quince is its rich antioxidant content. These compounds help protect your cells from oxidative damage caused by free radicals—unstable molecules that can contribute to chronic diseases and premature aging.

Quinces contain several types of antioxidants, including:

• Flavonols such as quercetin and kaempferol
• Phenolic compounds
• Vitamin C
• Catechins

Research indicates that the antioxidants in quinces may help reduce inflammation throughout the body and protect against conditions like heart disease, diabetes, and certain cancers. The fruit’s antioxidant activity remains significant even after cooking, making cooked quince preparations an excellent way to obtain these protective compounds.

2. Supports Digestive Health

Quinces have been used in traditional medicine for centuries to address various digestive complaints, and modern research supports several of these applications.

The fruit contains dietary fiber that promotes regular bowel movements and supports overall digestive function. Additionally, preliminary studies suggest that quince extract may help protect the gastrointestinal tract from damage associated with inflammatory bowel conditions.

Animal research has shown that quince extract can reduce colon tissue damage in models of ulcerative colitis, suggesting potential protective effects for the gut lining. The fruit’s compounds appear to work by reducing inflammation and supporting the integrity of the intestinal barrier.

Furthermore, quince contains pectin, a type of soluble fiber that acts as a prebiotic, feeding beneficial bacteria in your gut and supporting a healthy microbiome.

3. May Alleviate Pregnancy-Related Nausea

Morning sickness affects up to 80% of pregnant women, causing significant discomfort during early pregnancy. Emerging research suggests that quince syrup may offer relief from these symptoms.

A clinical study involving pregnant women found that quince syrup was more effective at reducing nausea and vomiting than a commonly recommended vitamin supplement. Participants who consumed one tablespoon of quince syrup daily experienced significant improvements in their symptoms.

While these results are promising, pregnant women should always consult with their healthcare provider before using any natural remedy, including quince products, to manage pregnancy symptoms.

4. Helps Manage Acid Reflux Symptoms

Gastroesophageal reflux disease (GERD) or acid reflux affects millions of people worldwide, causing uncomfortable symptoms like heartburn, regurgitation, and chest discomfort.

Several studies have investigated quince’s potential for managing acid reflux symptoms with encouraging results. Research conducted with both children and adults, including pregnant women, found that quince syrup was as effective as conventional approaches for relieving reflux symptoms.

One study involving children with acid reflux found that daily supplementation with quince concentrate alongside standard care improved symptoms including vomiting, food aversion, burping, and abdominal discomfort more effectively than standard care alone.

The mechanisms behind these effects aren’t fully understood but may relate to quince’s mucilage content, which can form a protective coating in the digestive tract.

5. May Protect Against Stomach Ulcers

Stomach ulcers are painful sores that develop in the lining of the stomach or upper small intestine, often caused by bacterial infection or prolonged use of certain pain medications.

Preliminary research suggests that quinces may offer protective benefits against stomach ulcers through multiple mechanisms. Laboratory studies have shown that quince juice can inhibit the growth of Helicobacter pylori, the bacterium responsible for most stomach ulcers.

Animal studies have also demonstrated that quince extract may protect stomach tissue from alcohol-induced ulcer formation, suggesting protective effects on the gastric lining.

While these early findings are encouraging, human clinical trials are needed to confirm these effects and determine effective dosages for ulcer prevention and management.

6. Supports Immune System Function

A robust immune system is essential for protecting your body against infections and diseases. Quinces provide several nutrients and compounds that support immune health.

First, quinces are a good source of vitamin C, with one medium fruit providing about 15% of your daily needs. Vitamin C is crucial for immune cell function and helps your body produce antibodies to fight off pathogens.

Additionally, laboratory studies have revealed that quince possesses antibacterial properties against various harmful bacteria, including E. coli and Staphylococcus aureus. These antimicrobial effects may help prevent infections and support your body’s natural defenses.

The fiber in quinces also supports immune health indirectly by nourishing beneficial gut bacteria. A healthy gut microbiome is increasingly recognized as crucial for proper immune function, as approximately 70% of immune cells reside in the digestive tract.

7. May Help Manage Allergic Reactions

Allergies occur when your immune system overreacts to normally harmless substances, causing symptoms like sneezing, runny nose, itchy eyes, and skin reactions.

Research suggests that compounds in quinces may help modulate immune responses and reduce allergic symptoms. The fruit appears to work by suppressing the activity of certain immune cells responsible for allergic reactions.

Some commercial allergy preparations combine quince extract with other natural ingredients. Small studies have shown promising results for managing mild allergic symptoms such as allergic rhinitis (hay fever) and mild asthma symptoms.

Animal studies have also demonstrated that quince extracts may help prevent and treat allergic skin reactions. However, more human research is needed to fully understand quince’s potential for allergy management and to establish effective dosing protocols.

8. Provides Anti-Inflammatory Benefits

Chronic inflammation is linked to numerous health conditions, including heart disease, diabetes, arthritis, and certain cancers. The antioxidants and phytonutrients in quinces may help combat inflammation throughout the body.

The flavonoids in quinces—particularly quercetin and kaempferol—have been studied extensively for their anti-inflammatory properties. These compounds work by inhibiting inflammatory pathways and reducing the production of inflammatory molecules in the body.

By incorporating anti-inflammatory foods like quinces into your diet, you may help reduce your risk of inflammation-related chronic diseases and support overall health and longevity.

How to Select and Store Quinces

When shopping for quinces, look for firm fruits with smooth, yellow skin. Avoid quinces with soft spots, bruises, or blemishes. The fruit should have a strong, pleasant fragrance when ripe.

If quinces are still greenish, allow them to ripen at room temperature until they turn golden yellow and become fragrant. This may take several days to a week.

Once ripe, quinces can be stored in the refrigerator for up to two weeks. Their strong aroma may affect other foods, so consider storing them in a separate drawer or sealed container.

Unripe quinces can be stored at room temperature for several weeks, making them a convenient fruit to keep on hand.

How to Prepare and Eat Quince

Unlike apples and pears, quinces are generally too hard and astringent to enjoy raw. However, cooking transforms them into a delicious treat. Here’s how to prepare quinces:

Basic Preparation

Start by washing the fruit thoroughly and rubbing off the fuzzy coating. Peel the quince, then cut it into quarters and remove the core and seeds. The flesh will be quite hard, so use a sharp knife and cut carefully.

Note that quince flesh oxidizes quickly when exposed to air, turning brown. To prevent discoloration, place cut pieces immediately into water with a splash of lemon juice.

Cooking Methods

Poaching: The most common preparation method is poaching. Place quince pieces in a pot with water, sugar, and aromatics like vanilla, cinnamon, or star anise. Simmer for 1-2 hours until the fruit becomes tender and turns a beautiful rosy color. The cooking liquid becomes a flavorful syrup.

Baking: Quinces can be baked similarly to apples. Arrange sliced quinces in a baking dish with sugar, butter, and spices. Cover and bake at 350°F (175°C) for about an hour until tender.

Roasting: Roasted quinces make an excellent accompaniment to savory dishes, especially roasted meats and game. Toss quince wedges with olive oil, honey, and herbs, then roast until caramelized.

Delicious Ways to Enjoy Cooked Quince

• Top your morning oatmeal or yogurt with poached quince slices
• Add cooked quinces to fruit tarts and pies
• Serve alongside roasted pork, lamb, or duck
• Blend cooked quince into smoothies
• Make quince paste (membrillo), a traditional delicacy perfect with cheese
• Prepare quince jam or jelly (though watch the sugar content)
• Add to compotes with other fall fruits like apples and pears
• Use in stuffing for poultry
