20 Foods Highest in Antioxidants (Ranked by ORAC Score)
Not all foods highest in antioxidants pull the same weight. In fact, some pack roughly 100 times more punch than others.
You know that wellness advice to “eat more antioxidants”? Here’s where it gets interesting.
If you’ve ever wondered which ones actually earn that title, this guide ranks them by the same lab measure scientists use. A few surprises included.
Key Takeaways
- Cloves and sumac top the chart for antioxidant density, with cinnamon, wild blueberries, and dark chocolate close behind.
- A 2024 systematic review in Nutrients linked higher polyphenol intake to lower cardiovascular disease risk.
- Aim for 5 servings of brightly colored plant foods a day, plus a daily dash of spices, for steady antioxidant intake.
- ORAC scores measure lab activity, not what actually happens inside your body. Variety beats chasing a top number.

What ORAC Actually Means
ORAC (Oxygen Radical Absorbance Capacity) is a lab-based score that measures how strongly a food’s antioxidants neutralize free radicals in a test tube. Higher number, more antioxidant punch on paper.
Researchers at the USDA developed the system in the 1990s to compare plant foods by their antioxidant strength. However, the scale is open-ended, and most foods land between 100 and 100,000 micromoles per 100 grams.
Here’s the catch.
ORAC was always meant as a research tool, not a nutrition label. It measures what antioxidants do in a beaker, not what they do once they hit your gut, blood, and cells.
Still, it remains the most consistent way to compare raw antioxidant capacity across foods.
Think of it as a horsepower rating for produce.
A high number tells you the engine has potential, not how it drives in traffic.
That doesn’t make the scale useless.
Plenty of dietitians and researchers still reach for ORAC when ranking the foods highest in antioxidants. The number captures something real about a food’s chemistry.
20 Foods Highest in Antioxidants (ORAC Ranked)
Sumac and cloves top the chart for antioxidant density. Among foods you’d eat in normal portions, wild blueberries, dark chocolate, and pecans lead this guide to the 20 foods highest in antioxidants. The table below ranks them by ORAC value per 100 grams.
| Food | ORAC (per 100g) | Typical Serving | Standout Antioxidant |
|---|---|---|---|
| Sumac, ground | 312,400 | 1 tsp (2g) | Gallic acid |
| Cloves, ground | 290,283 | 1 tsp (2g) | Eugenol |
| Cinnamon, ground | 267,536 | 1 tsp (3g) | Cinnamaldehyde |
| Oregano, dried | 200,129 | 1 tsp (1g) | Rosmarinic acid |
| Turmeric, ground | 159,277 | 1 tsp (3g) | Curcumin |
| Acai, powdered | 102,700 | 1 tbsp (5g) | Anthocyanins |
| Cocoa, raw powder | 80,933 | 1 tbsp (5g) | Flavanols |
| Sorghum bran, red | 71,000 | 2 tbsp (15g) | Phenolic acids |
| Goji berries, dried | 25,300 | 1 oz (28g) | Zeaxanthin |
| Dark chocolate (70%+) | 20,816 | 1 square (10g) | Flavanols |
| Pecans, raw | 17,940 | 1 oz (28g) | Ellagic acid |
| Wild blueberries | 9,621 | 1 cup (148g) | Anthocyanins |
| Cranberries, raw | 9,584 | 1/2 cup (50g) | Proanthocyanidins |
| Artichoke, cooked | 9,416 | 1 medium (120g) | Chlorogenic acid |
| Cultivated blueberries | 6,552 | 1 cup (148g) | Anthocyanins |
| Blackberries, raw | 5,905 | 1 cup (144g) | Anthocyanins |
| Raspberries, raw | 5,065 | 1 cup (123g) | Ellagitannins |
| Pomegranate, raw | 4,479 | 1/2 cup (87g) | Punicalagins |
| Strawberries, raw | 4,302 | 1 cup (152g) | Pelargonidin |
| Kale, raw | 1,770 | 1 cup (67g) | Lutein |
A few quick notes on these numbers.
ORAC values come from the USDA’s 2010 reference table and peer-reviewed lab measurements published since. They reflect raw food, not cooked, so heat and processing can shift the numbers a bit.
Berries Lead the Pack
Berries earn their reputation. Wild blueberries, blackberries, and cranberries deliver some of the densest antioxidant loads in any whole food.
Wild blueberries are the standout. They pack roughly 50% more antioxidants per gram than the larger cultivated kind, mostly thanks to anthocyanins (the pigments behind their deep blue color).
Here’s the everyday move: keep a bag of frozen wild blueberries in your freezer. Studies suggest freezing barely dents their antioxidant content, and they cost a fraction of fresh.
What about the other berries?
Blackberries and cranberries hit nearly as hard. Cranberries are especially rich in proanthocyanidins, the compounds linked to urinary tract benefits.
Goji berries, raspberries, and strawberries earn a spot too, even with lower ORAC scores. For more on why these little fruits punch above their weight, see our full guide to blueberry benefits.
Also worth knowing: among the foods highest in antioxidants, berry color is a real clue.
Deep reds, blues, and purples mean more anthocyanins, while the brighter strawberry pinks point to pelargonidin. So when in doubt, eat the rainbow.
Spices to Add Daily
Spices are the dark horses of the antioxidant world. Just a teaspoon of cinnamon or cloves can outpace a full cup of fresh berries on the ORAC scale.
Cloves top almost every antioxidant list, and they’re not just for holiday baking. Add a pinch to coffee, oatmeal, or roasted sweet potatoes for a quick lift.
Just remember they’re powerful in small doses.
Even a quarter teaspoon goes a long way in cooking, baking, or coffee.
Cinnamon brings cinnamaldehyde, the compound behind both its flavor and its blood-sugar research. A 2019 meta-analysis in Diabetes Research found that daily cinnamon modestly lowered fasting glucose in adults with type 2 diabetes. The doses ranged from 1 to 6 grams a day.
Five easy ways to use high-antioxidant spices daily:
- Stir cinnamon into morning coffee or yogurt
- Sprinkle ground cloves over oatmeal or baked apples
- Add turmeric to scrambled eggs, rice, or roasted veggies
- Toss oregano on salads, pizza, and pasta
- Mix sumac into hummus or roasted root vegetables
What matters most is consistency.
A daily dash of these foods highest in antioxidants beats a once-a-month curry blowout every time.
Do ORAC Scores Actually Matter in Real Life?
Sort of. ORAC scores tell you how much antioxidant activity exists in a food, but they don’t predict how those antioxidants behave inside your body.
The USDA actually pulled its public ORAC database in 2012. The agency cited “no evidence” that the values translated to real-world health benefits. That sounds harsh, but it makes sense.
When you eat a blueberry, your body absorbs only a fraction of its anthocyanins. Some get broken down before they reach your bloodstream. Others get reshaped by gut bacteria into entirely different compounds.
So why bother with ORAC at all?
Because foods with high ORAC scores tend to be rich in polyphenols, fiber, and vitamins, all of which do have measurable benefits. A 2024 systematic review in Nutrients found that polyphenol intake improved several cardiometabolic risk markers.
The takeaway: use ORAC as a rough guide, not gospel.
Variety, color, and consistency matter more than chasing any single number.
Plus, the antioxidant compounds in the foods highest in antioxidants rarely act alone. They pair with fiber, vitamins, and minerals your body actually uses.
How to Get More Antioxidants Every Day
The simplest path is to add one antioxidant-rich food to every meal, not a giant “superfood smoothie” once a week.
Spreading intake across the day helps your body absorb more polyphenols than any single megadose. Here’s a no-nonsense daily template:
- Breakfast: berries on yogurt or oatmeal, with a sprinkle of cinnamon
- Lunch: leafy greens like kale or spinach, plus a small handful of pecans for ellagic acid and zinc
- Snack: a square of dark chocolate at 70% or higher with a few pistachios for a green-pigment lift
- Dinner: roasted vegetables with garlic, turmeric, and olive oil
- Drink: green tea or coffee, both proven antioxidant sources
One easy upgrade: swap your usual snack chips for a small handful of nuts and a few squares of dark chocolate. Even that small change moves you toward the foods highest in antioxidants every day.
If you want a single cheat code, make berries non-negotiable. Frozen, fresh, or freeze-dried, they’re the easiest way to load up on antioxidants without thinking about it.

The Bottom Line
You don’t need a chemistry degree to eat for antioxidants. The foods highest in antioxidants are already familiar: berries, dark chocolate, spices, nuts, and brightly colored produce.
Use ORAC scores as a starting map, not a destination. Aim for variety, eat the rainbow, and lean into spices for outsized impact. Most of all, make antioxidants a daily habit instead of a once-a-month overhaul.
Cruciferous vegetables top many antioxidant lists — see our broccoli health benefits guide for the most-researched single food.

Antioxidant Foods FAQ
What food has the highest antioxidants?
Sumac and cloves top the ORAC chart at over 290,000 units per 100 grams, but you’d never eat that much in one go. Among foods you’d eat in normal portions, wild blueberries and dark chocolate (70% or higher) are the practical winners.
Are berries really the best whole-food source of antioxidants?
Berries are among the densest whole-food sources, especially wild blueberries, blackberries, and cranberries. Their high anthocyanin content gives them strong ORAC scores and a consistent research base on heart and brain health. Variety still beats sticking to one favorite.
Do antioxidant supplements work as well as food?
No, and several large trials suggest high-dose supplements can be counterproductive. Whole foods deliver antioxidants alongside fiber, polyphenols, and cofactors your body actually uses. Stick with food first, supplements only if a clinician recommends one.
How much antioxidant food should I eat per day?
Aim for at least 5 servings of brightly colored fruits and vegetables, plus a daily dash of spices and one or two servings of nuts or dark chocolate. Spreading intake across meals beats one big dose.
Are ORAC scores still reliable?
ORAC is useful for comparing antioxidant capacity in the lab, but it’s not a perfect predictor of what happens in your body. The USDA discontinued its public database in 2012 for that reason. Use ORAC as a rough guide, not a definitive ranking.
