The question of whether cherries cause inflammation in the body is a prevalent one, often stemming from confusion about how different foods affect our health. However, a significant body of research indicates that cherries, far from causing inflammation, are actually potent allies in the fight against it. The key lies in their rich concentration of antioxidants and other beneficial plant compounds.
The Anti-Inflammatory Power of Cherries
The powerful anti-inflammatory effects of cherries are primarily attributed to their high levels of polyphenols and vitamin C. These compounds actively combat oxidative stress, a process that can trigger chronic inflammation and contribute to conditions like cancer, diabetes, and heart disease.
Key Anti-inflammatory Compounds
- Anthocyanins: These flavonoids give cherries their deep red and purple hues. They are potent antioxidants that block the production of inflammatory proteins, similar to the action of some over-the-counter anti-inflammatory drugs.
- Flavonols: Cherries contain flavonols like quercetin, which also possess strong antioxidant and anti-inflammatory properties.
- Polyphenols: A broader category of plant compounds, polyphenols are abundant in cherries and help protect against cellular damage and reduce inflammation.
Types of Cherries: A Closer Look at Tart vs. Sweet
While all cherries offer health benefits, there are notable differences between the two main varieties: tart (or sour) cherries and sweet cherries. Most of the early research focused on tart cherries, but newer studies confirm that sweet varieties like Bing also have significant anti-inflammatory effects.
| Feature | Tart Cherries (e.g., Montmorency) | Sweet Cherries (e.g., Bing) |
|---|---|---|
| Flavor | Sour, ideal for cooking, juice, and supplements | Sweet, perfect for snacking fresh |
| Anthocyanin Content | Very high, often more concentrated in juice form | Also high, responsible for the deep red color |
| Melatonin Content | Natural source of melatonin, supporting sleep | Also contain melatonin, but tart varieties are more widely studied for sleep benefits |
| Common Use | Juice, dried fruit, supplements, baked goods | Fresh consumption, dried fruit |
| Research Focus | Extensively studied for muscle recovery and sleep | Research also supports anti-inflammatory properties |
Cherries and Specific Inflammatory Conditions
Research has explored how cherry consumption can help alleviate symptoms of several inflammatory-related health issues.
Gout Relief
Gout is a form of inflammatory arthritis caused by an accumulation of uric acid crystals in the joints. Studies consistently show that consuming cherries or cherry juice can lower blood uric acid levels and significantly reduce the risk of gout attacks.
Arthritis Symptom Reduction
Some studies suggest that the anti-inflammatory properties of cherries can help alleviate pain and inflammation associated with osteoarthritis. A study involving patients with knee osteoarthritis who drank a tart cherry juice blend showed a reduction in their symptoms.
Enhanced Exercise Recovery
For athletes and fitness enthusiasts, strenuous exercise can cause muscle damage and soreness, a form of inflammation.
- Drinking tart cherry juice has been shown to minimize post-run muscle pain and aid in recovery after endurance events.
- Another study found that tart cherry extract reduced oxidative stress and markers of muscle damage after strength training.
How to Incorporate Cherries into Your Diet
Including cherries in your diet is simple, and they can be enjoyed in many forms:
- Fresh: Enjoy fresh sweet or tart cherries when in season as a healthy snack.
- Juice: Drink 100% tart cherry juice, but be mindful of added sugars. Some studies have shown effects with 1-2 cups per day.
- Dried: Add dried cherries to trail mix, oatmeal, or baked goods.
- Frozen: Blend frozen cherries into smoothies for a refreshing treat.
- Supplements: Cherry extract supplements are available, but it is important to choose standardized products to ensure consistent potency.
Understanding the Science of Inflammation Reduction
The anti-inflammatory mechanism of cherries involves the inhibition of enzymes called cyclooxygenases (COX-1 and COX-2). These enzymes play a central role in producing prostaglandins, compounds that mediate pain and inflammation in the body. The anthocyanins in cherries have been found to act as natural COX inhibitors, similar to how non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen work, but without the associated gastrointestinal side effects.
Risks and Considerations
While generally safe for most people, there are a few considerations:
- Allergies: Individuals with allergies to other stone fruits like peaches or plums may also be allergic to cherries.
- Gastrointestinal Issues: Excessive consumption of cherries or cherry juice can cause digestive discomfort like bloating or diarrhea due to their fiber and sugar content, especially for those with fructose intolerance.
- Oxalates: Cherries, particularly tart cherries, contain oxalates, which can contribute to kidney stones in susceptible individuals. Moderation is key if you have a history of kidney stones.
Conclusion
In summary, the notion that cherries cause inflammation is false; in fact, the opposite is true. Cherries are a rich source of anti-inflammatory and antioxidant compounds, especially anthocyanins, that have been scientifically shown to help manage chronic inflammation. Whether enjoyed fresh, juiced, or dried, including cherries in your regular diet can be a delicious and beneficial strategy for reducing inflammatory markers, aiding in muscle recovery, and potentially alleviating symptoms of conditions like gout and arthritis.

Key Takeaways
- Cherries Fight Inflammation, They Don't Cause It: The primary bioactive compounds in cherries, like anthocyanins, have scientifically-backed anti-inflammatory effects.
- Rich in Powerful Antioxidants: Cherries help combat oxidative stress, which is a key contributor to chronic inflammation and cellular damage.
- Relief for Specific Conditions: Regular cherry consumption can reduce symptoms related to gout, arthritis, and exercise-induced muscle soreness.
- Choose Tart for Concentrated Benefits: While both varieties are healthy, tart cherries are often highlighted in research for their potent anti-inflammatory properties, especially in concentrated forms.
- Multiple Ways to Enjoy: You can gain health benefits from cherries by eating them fresh, frozen, dried, or as juice.
- Safe for Most People: The risks are minimal, primarily related to allergies or overconsumption, making them a safe dietary addition for most.
