11 Best Foods Rich in Polyphenols for People with Inflammation

Inflammation is a natural immune response that helps the body heal from injuries and fight infections. However, when inflammation becomes chronic, it can contribute to a wide range of health problems, including heart disease, arthritis, diabetes, and autoimmune disorders. One of the most effective ways to combat chronic inflammation is through diet, specifically by consuming foods rich in polyphenols. Polyphenols are natural compounds found in plants that have antioxidant, anti-inflammatory, and immune-modulating properties.
In this article, we’ll explore the 11 best foods rich in polyphenols that can help reduce inflammation, improve overall health, and protect the body from chronic diseases.
1. Berries
Berries, including blueberries, strawberries, raspberries, and blackberries, are some of the most polyphenol-rich foods you can add to your diet. These fruits are packed with anthocyanins, a type of polyphenol that gives berries their vibrant colors and has potent anti-inflammatory effects. Anthocyanins help reduce the production of pro-inflammatory markers in the body, protect cells from oxidative stress, and enhance the body’s natural antioxidant defenses.
Berries are also rich in fiber and vitamin C, both of which support immune health and help reduce inflammation. Studies have shown that regular consumption of berries can lower levels of C-reactive protein (CRP), a marker of inflammation, and reduce the risk of chronic conditions like heart disease and type 2 diabetes.
Incorporating a variety of berries into your daily diet—whether in smoothies, salads, or as a snack—can help fight inflammation and support overall health.
2. Green Tea
Green tea is renowned for its high concentration of polyphenols, particularly catechins like epigallocatechin gallate (EGCG), which have powerful anti-inflammatory and antioxidant properties. EGCG helps reduce the production of inflammatory chemicals in the body, protect cells from oxidative damage, and support healthy immune function.
Research has shown that green tea can reduce markers of inflammation and help protect against chronic diseases like cardiovascular disease, arthritis, and certain types of cancer. Green tea’s ability to modulate the immune system also makes it an effective natural remedy for autoimmune conditions.

Dark chocolate is rich in flavonoids, a type of polyphenol that has been shown to reduce inflammation, improve heart health, and enhance brain function. The higher the cacao content, the richer the chocolate is in polyphenols, with varieties containing at least 70% cacao offering the most benefits.
Flavonoids in dark chocolate help reduce the production of pro-inflammatory cytokines and improve blood flow, which can reduce inflammation in the body’s tissues. They also have antioxidant properties that protect cells from oxidative stress, which is a key factor in chronic inflammation and disease development.
In addition to its anti-inflammatory benefits, dark chocolate has been shown to improve insulin sensitivity and support metabolic health, making it a great treat for those looking to manage inflammation and support long-term health.
Enjoying a small piece of dark chocolate daily can help reduce inflammation and provide a delicious source of polyphenols.
4. Extra Virgin Olive Oil
Extra virgin olive oil is a staple of the Mediterranean diet, which is known for its anti-inflammatory effects. Olive oil is rich in oleocanthal, a polyphenol that acts as a natural anti-inflammatory compound, similar to ibuprofen. Oleocanthal helps reduce the production of pro-inflammatory enzymes and supports overall cardiovascular health.
In addition to oleocanthal, olive oil contains other polyphenols like hydroxytyrosol and tyrosol, which have antioxidant and anti-inflammatory properties. These compounds help protect the heart, reduce inflammation in the arteries, and improve blood flow.
Studies have shown that consuming extra virgin olive oil regularly can lower markers of inflammation, reduce the risk of heart disease, and support healthy brain function.
Using extra virgin olive oil in salad dressings, drizzling it over vegetables, or using it for cooking can provide a delicious and anti-inflammatory addition to your meals.
5. Turmeric
Turmeric is a powerful anti-inflammatory spice that contains curcumin, a polyphenol known for its potent anti-inflammatory and antioxidant properties. Curcumin helps inhibit the production of pro-inflammatory molecules like cytokines and enzymes, which are involved in chronic inflammation and disease progression.
Turmeric’s ability to reduce inflammation makes it particularly beneficial for people with conditions like arthritis, inflammatory bowel disease (IBD), and autoimmune disorders. Curcumin also supports joint health, reduces pain and swelling, and promotes faster recovery from injuries.
To enhance curcumin’s absorption, it’s recommended to consume turmeric with a source of healthy fat or black pepper, which contains piperine, a compound that boosts curcumin’s bioavailability.
Adding turmeric to your diet—whether in curries, soups, or golden milk—can provide powerful anti-inflammatory benefits and support overall health.
6. Grapes
Grapes, especially red and purple varieties, are another excellent source of polyphenols, particularly resveratrol. Resveratrol is a potent antioxidant that helps reduce inflammation, protect the heart, and improve metabolic health.
Research has shown that resveratrol can lower markers of inflammation, such as C-reactive protein (CRP), and reduce the risk of chronic conditions like heart disease, diabetes, and neurodegenerative diseases. In addition to resveratrol, grapes contain other flavonoids and anthocyanins that further support cardiovascular health and protect cells from oxidative damage.
Including grapes in your diet—whether fresh, in salads, or as part of a snack—can provide a natural source of polyphenols that help reduce inflammation and promote overall health.
7. Apples
Apples are rich in quercetin, a type of polyphenol that has powerful anti-inflammatory and antioxidant properties. Quercetin helps reduce the production of pro-inflammatory molecules, improve immune function, and protect against chronic diseases like heart disease, asthma, and diabetes.
In addition to quercetin, apples contain fiber and other phytonutrients that support gut health and promote healthy digestion. Since inflammation often starts in the gut, maintaining a healthy digestive system is crucial for managing chronic inflammation.
Eating apples with the skin on maximizes the intake of polyphenols, as the skin contains the highest concentration of these beneficial compounds.
Incorporating apples into your diet—whether as a snack or in salads—can help reduce inflammation and support overall health.
8. Red Onions
Red onions are one of the richest sources of quercetin, a polyphenol with powerful anti-inflammatory properties. Quercetin helps reduce inflammation by inhibiting the production of pro-inflammatory cytokines and enzymes. It also acts as an antioxidant, protecting cells from oxidative damage.
