The Anti-Inflammatory Power of Cashews
Cashews are more than just a tasty snack; they are packed with nutrients that can help combat inflammation. This is thanks to their rich content of antioxidants and healthy fats, which work to protect the body's cells and reduce oxidative stress.
Key Anti-Inflammatory Compounds in Cashews
- Antioxidants: Cashews are a significant source of antioxidants, including polyphenols and carotenoids. These powerful plant compounds neutralize harmful free radicals that can damage cells and trigger inflammation. Research has shown that cashew nut consumption can significantly reduce markers of inflammation and oxidative stress in animal models.
- Healthy Fats: The primary fat in cashews is heart-healthy monounsaturated fat. These fats are known to support cardiovascular health and have been linked to anti-inflammatory effects within the body. While cashews also contain omega-6 fatty acids, the focus is on the overall nutritional profile and how it contributes to a balanced diet.
- Essential Minerals: Cashews provide essential minerals like magnesium, zinc, and copper, which are crucial for immune function and play a role in regulating the body's inflammatory pathways.
The Impact of Roasting: Raw vs. Roasted
The act of roasting nuts changes their chemical composition, affecting everything from flavor and texture to nutrient availability. When considering if roasted cashews are anti-inflammatory, it's important to weigh the potential changes.
Effects of Roasting on Nutrients
- Antioxidant Activity: Some studies have paradoxically found that roasting cashews, particularly at certain temperatures and for specific durations, can increase their antioxidant activity compared to raw nuts. This is potentially due to the formation of new antioxidant compounds during the heating process. However, other studies note a potential loss of heat-sensitive antioxidants and vitamins when roasted at high temperatures.
- Oxidation of Fats: Cashews' healthy polyunsaturated fats are more susceptible to oxidation when exposed to high heat. While this process is minimized during controlled, low-temperature roasting, it can increase with higher temperatures and prolonged heating. This can affect the fat's quality and shelf life.
- Nutrient Loss: Heat-sensitive vitamins, such as some B vitamins and vitamin E, can be degraded during the roasting process. While nuts are not primary sources for some of these, the loss can be notable. Minerals like magnesium, phosphorus, and zinc, however, remain largely unaffected as they are heat-stable.
Raw vs. Roasted: A Comparison
To make an informed decision, here is a comparison of raw and roasted cashews based on key nutritional and anti-inflammatory factors.
| Feature | Raw Cashews | Roasted Cashews (Dry-roasted, unsalted) |
|---|---|---|
| Antioxidant Content | Contains natural antioxidants like carotenoids and polyphenols. Some studies suggest raw has higher heat-sensitive antioxidant levels, while others find roasted can have higher overall antioxidant activity. | Potential for increased antioxidant activity due to the formation of new compounds, depending on temperature and duration. Minimal loss of some heat-sensitive vitamins when roasted properly. |
| Healthy Fats | Healthy monounsaturated and polyunsaturated fats remain largely intact. | Healthy fats are retained, but polyunsaturated fats can become more susceptible to oxidation, especially at high temperatures. |
| Flavor & Texture | Milder flavor, softer and chewier texture. | Stronger, nuttier flavor and a satisfying crunch. The taste is enhanced by the roasting process. |
| Digestibility | For some individuals, raw nuts might be harder to digest due to their natural compounds. | Roasting can break down some compounds, making the cashews easier to digest for some people. |
| Additives (Salt/Oil) | No additives present, ensuring zero added sodium or oils. | Commercial varieties often contain added salt and/or oil, which can counteract anti-inflammatory benefits, especially in excess. The healthiest option is unsalted or dry-roasted at home. |
Choosing the Best Option for Anti-Inflammatory Benefits
For minimizing inflammation, both raw and dry-roasted, unsalted cashews are healthy choices when consumed in moderation. The choice ultimately depends on personal preference for taste and texture. If you choose roasted cashews, opt for dry-roasted and unsalted varieties to avoid added sodium and unhealthy oils that could negate the anti-inflammatory benefits.
Practical Tips for Incorporating Cashews
- Snack on them: A handful of raw or unsalted dry-roasted cashews is a perfect and satisfying snack between meals.
- Add to dishes: Sprinkle chopped cashews over salads or stir-fries for added crunch and nutrients.
- Make cashew cream: Soaked and blended raw cashews can create a creamy, dairy-free sauce for soups or pastas.
Conclusion
The question "Are roasted cashews anti-inflammatory?" can be answered with a qualified yes. Both raw and roasted cashews contain compounds like antioxidants and healthy fats that exhibit anti-inflammatory properties, supported by scientific research. While the roasting process can cause minor alterations in nutrient levels, studies show that roasted cashews can still be highly beneficial, and may even have increased antioxidant activity in some cases. For the best results, stick to plain, unsalted varieties and enjoy them as part of a balanced, whole-foods anti-inflammatory diet.

What are anti-inflammatory foods?
Anti-inflammatory foods help reduce chronic inflammation in the body and often include fruits, vegetables, nuts, seeds, healthy fats, and fatty fish.
Are cashews good for inflammation?
Yes, cashews are a good food to include in an anti-inflammatory diet. They contain antioxidants, monounsaturated fats, and minerals that help combat oxidative stress and inflammation.
Is it better to eat raw or roasted cashews for inflammation?
Both are good options. Raw cashews retain all heat-sensitive nutrients, but some studies indicate that roasted cashews can have higher overall antioxidant activity. The key is to choose unsalted and dry-roasted varieties over oil-fried.
How does roasting affect antioxidants in cashews?
The effect is complex. Roasting can reduce some heat-sensitive antioxidants, but it can also form new ones through chemical reactions, potentially leading to an overall increase in antioxidant activity compared to raw.
How many cashews should I eat daily to help with inflammation?
For health benefits, a serving of about one ounce (18 medium cashews) daily is often recommended. This provides nutrients without excessive calories or fat intake.
Do all nuts help with inflammation?
Many tree nuts, including cashews, almonds, and walnuts, are rich in beneficial compounds that can help reduce inflammation. However, their specific nutritional profiles differ.
Can salty roasted cashews be bad for inflammation?
Yes, excessive sodium intake from salted nuts can contribute to high blood pressure and other health issues that may increase inflammation, potentially counteracting the nuts' benefits.
Is frying cashews in oil bad for inflammation?
Frying in oil can introduce less-healthy fats and potentially damage the natural fats in cashews. Dry roasting is a healthier preparation method that retains more nutritional integrity.
