The pursuit of a healthy lifestyle often leads us to explore the benefits of antioxidants. These compounds play a crucial role in protecting cells from damage and may help reduce the risk of chronic diseases. While green tea is widely recognized for its antioxidant properties, other foods may offer even higher levels. Here’s a closer look at some of these powerhouse foods.
Foods like berries, nuts, seeds, coffee, and kale contain more antioxidants than green tea.

-
Berries, kale, cocoa, spices, seeds, nuts, and coffee can provide antioxidant levels equal to or higher than those of green tea.
-
Polyphenols and vitamins in these foods help protect cells, reduce inflammation, and lower disease risk.
-
Eating a variety of whole, minimally processed foods is the best way to increase antioxidant intake.
Green tea is well-known for its high antioxidant content, providing about 570-2,620 micromoles per 100 milliliters. However, several other foods boast an even greater antioxidant capacity, making them worthy additions to a health-conscious diet.
1. Berries
Berries get their blue and purple hues from antioxidant plant pigments called anthocyanins.

Berries serve as a significant source of antioxidants, containing essential nutrients such as vitamins A, C, E, and the mineral selenium, among other compounds. They are abundant in vitamin C, particularly blackcurrants and sea buckthorn berries, with a cup of mixed berries supplying 26 milligrams (mg) of vitamin C, which constitutes 29% of the Daily Value (DV).
High in anthocyanins—a type of polyphenol and plant pigment—most berries demonstrate an antioxidant capacity ranging from approximately 2,100 to over 15,000 micromoles (μmol) per 100 grams. Notably, berries with the highest antioxidant capacity include:
Health Benefits of Polyphenols
Polyphenols, found mainly in whole grains, fruits, vegetables, nuts, seeds, spices, and herbs, play a vital role in health. Over 8,000 types have been identified thus far, many of which display antioxidant properties that help mitigate cell damage, inflammation, and disease risk.
A recent study indicated that a diet rich in polyphenols is associated with a 20% reduction in mortality risk, alongside a 40% decrease in cardiovascular disease mortality risk.
2. Kale
Kale is rich in vitamins with antioxidant properties, like vitamins A and C.

Vegetables are another outstanding source of antioxidants. In a study of 303 vegetables, the average antioxidant capacity was about 800 micromoles per 100 grams. Notably, curly kale boasted an impressive antioxidant capacity of roughly 2,800 micromoles per 100 grams, while being abundant in vitamins A and C as well as polyphenols.
Additional vegetables known for their high antioxidant content include artichokes, red chili peppers, and green chili peppers.
3. Cocoa
Cocoa is a good source of antioxidants that help lower inflammation and prevent disease.

Cocoa powder can contain approximately 636 micromoles of antioxidants per gram, making dark chocolate that uses a high percentage of cocoa particularly rich in antioxidants.
Consuming foods high in antioxidants could potentially aid in reducing inflammation and preventing disease. A 2023 study reported that ingesting 10 grams of polyphenol-rich cocoa reduced heart-health-related inflammation. Furthermore, a 2024 study indicated that regular cocoa consumption was associated with lower blood cholesterol levels.
4. Spices
Spices and herbs like clove, cinnamon, thyme, sage, and saffron have strong antioxidant properties.

Spices, derived from the seeds, bark, roots, or leaves of plants, are notably rich in polyphenols. A 2024 study assessed 425 spices and herbs, identifying clove as possessing the highest antioxidant capacity, followed closely by peppermint, allspice, cinnamon, oregano, thyme, sage, rosemary, saffron, and tarragon, with capacities ranging from 440 to 2,770 micromoles per gram.
5. Seeds
Seeds are an excellent source of antioxidants, including sunflower, sesame, and hemp seeds.

Seeds are packed with antioxidant nutrients such as vitamins A and E, as well as polyphenols. A 2020 study evaluated the antioxidant capacity of five different seeds, revealing that sunflower seeds had the highest capacity, followed by flaxseeds, sesame seeds, poppy seeds, and hemp seeds.
Here is the antioxidant content of those seeds:
-
Sunflower seed: 450 µmol/g
Additionally, research has shown that germinating seeds, such as chia seeds, can significantly enhance their antioxidant capacity, increasing by approximately 87-105% after four days of germination.
6. Nuts
Nuts are rich in vitamins and compounds with powerful antioxidant effects.

Nuts are abundant in antioxidant nutrients and valuable plant compounds. A 2025 study indicated that consuming 60 grams or more of almonds daily may lower oxidative stress levels and enhance antioxidant enzyme activity, providing cellular protection. Furthermore, research suggests that regular consumption of nuts may also reduce overall mortality risk.
The following outlines the antioxidant capacities of several nuts:
Certain types of nuts, including almonds, hazelnuts, pine nuts, and Brazil nuts, are notably rich in vitamin E, while Brazil nuts are especially high in selenium as well.
7. Coffee

Coffee is among the beverages highest in antioxidants, containing approximately 75 to 172 micromoles of antioxidants per gram of ground coffee. Factors such as the specific coffee bean variety, roasting method, and brewing technique can influence the antioxidant concentration.
A study conducted in 2020 revealed that Aeropress coffee exhibited the highest antioxidant capacity, with drip coffee following, then pour-over, espresso, and French press.
Exact Antioxidant Levels in Foods Are Hard To Tell
Determining the precise antioxidant content of food can be challenging since it varies based on cultivation, storage, and preparation methods. Moreover, each food item contains various types of antioxidants, complicating the measurement process.
Different methods for testing antioxidant levels can yield varying results, potentially leading to discrepancies in the reported amounts for the same food item.
How To Get More Antioxidants in Your Diet
To boost antioxidant intake, consider these strategies:
-
Eat a variety of foods: Different foods contain diverse types of polyphenols, each offering distinct health benefits. Incorporate an assortment of whole grains, fruits, vegetables, nuts, and seeds in your diet.
-
Use herbs and spices: Enhance your meals or beverages by adding various herbs and spices to increase antioxidant content. For instance, you can make a golden latte with turmeric, sprinkle cinnamon on oatmeal, add cloves to tea, or incorporate ginger into smoothies or stir-fries.
-
Drink antioxidant-rich beverages: Beverages such as tea, coffee, and cocoa are excellent sources of antioxidants. Consume them in moderation to avoid potential caffeine-related side effects.
-
Minimize ultra-processed foods: Opting for whole, minimally processed foods typically maximizes antioxidant intake compared to highly processed options.
