Dried fruits are a convenient and nutrient-dense way to consume antioxidants, which help combat oxidative stress in the body by neutralizing harmful free radicals. While many fresh fruits are excellent sources, the dehydration process concentrates their nutrients, resulting in a potent snack. The answer to the question, "Which dried fruit is highest in antioxidants?" often points to prunes, but several other dried fruits offer significant antioxidant benefits.
The Antioxidant Powerhouse: Prunes (Dried Plums)
Studies confirm that dried plums, commonly known as prunes, possess an incredibly high antioxidant capacity, often measured using the Oxygen Radical Absorbance Capacity (ORAC) scale. This powerhouse ranking is attributed to their high concentration of polyphenols and other phytonutrients. Beyond their antioxidant content, prunes are celebrated for their natural laxative effect, digestive support from fiber and sorbitol, and contribution to bone health due to their boron content.
Other Top Contenders
While prunes may take the top spot, other dried fruits also deserve a place in your diet for their robust antioxidant profiles.
Goji Berries
These vibrant red berries were once considered the highest antioxidant-packed dried fruit, with potent concentrations of polyphenols and carotenoids. Their high antioxidant activity is particularly effective against cellular damage.
Dates
Dates contain some of the highest concentrations of polyphenols among dried fruits, according to some research. They are also an excellent source of fiber, potassium, and iron, offering significant antioxidant protection.
Figs
Dried figs are another formidable source of antioxidants, and studies show that their antioxidants can be readily absorbed by the body. They also provide a good source of fiber, potassium, and other essential nutrients.
Raisins
Derived from grapes, raisins also have a high antioxidant capacity, with phenolic antioxidants that are well-absorbed by the body. They are rich in fiber and potassium and have been linked to improved blood sugar and cholesterol control.
Dried Cranberries
Known for their vibrant red color, dried cranberries are rich in antioxidants, though often contain added sugar. They contain flavonoids like quercetin and myricetin, which have anti-inflammatory and protective properties.

How to Choose the Best Dried Fruit for You
Selecting the best dried fruit depends on your specific health goals and personal taste. If you are prioritizing a general antioxidant boost, prunes are an excellent choice due to their proven potency. For focused benefits, such as eye health, goji berries are a great option due to their carotenoid content. When making your selection, always read the nutrition label carefully.
Here are some tips for incorporating high-antioxidant dried fruits into your diet:
- Read the ingredients. Look for dried fruits with no added sugars or preservatives like sulfites. Sulfites are often used to preserve the color of brighter fruits but can cause issues for sensitive individuals.
- Mind your portion size. Dried fruits are energy-dense, so a little goes a long way. A typical portion is a quarter-cup.
- Use them as a natural sweetener. Incorporate chopped dates or raisins into baked goods, oatmeal, or smoothies as a healthier alternative to refined sugar.
- Add to savory dishes. Dried fruits can add a touch of sweetness and depth to savory dishes, like salads, couscous, or grain bowls.
- Create a custom trail mix. Combine a variety of antioxidant-rich dried fruits with nuts and seeds for a balanced, nutrient-packed snack.
Conclusion: Making the Best Choice
While scientific studies frequently point to prunes as the leader in antioxidant capacity, the "best" dried fruit is ultimately a matter of personal preference and dietary goals. What is clear, however, is that incorporating a variety of dried fruits like prunes, goji berries, and figs offers a significant health advantage. By paying attention to ingredients and portion sizes, you can effectively boost your antioxidant intake and enjoy the numerous health benefits these convenient snacks provide.

Are dried fruits less healthy than fresh fruits?
Despite popular belief, dried fruits can sometimes be even more nutrient-dense than their fresh counterparts on a per-gram basis, as the water is removed during drying. While some nutrients like Vitamin C may be diminished, the concentration of other beneficial compounds, including phenolic antioxidants and fiber, is often higher. The primary nutritional difference is that dried fruits are much higher in calories and sugar by weight, requiring mindful portion control.
What is the difference between prunes and dates?
Prunes are dried plums and are a well-known source of fiber and antioxidants, particularly valued for promoting digestive health. Dates are a different type of fruit entirely, coming from the date palm tree. While also rich in antioxidants and fiber, dates have a distinct, caramel-like sweetness and are often used as a natural sugar substitute. Both are healthy, but their nutritional profiles and flavors differ.
Can all dried fruits be considered antioxidant-rich?
While most fruits contain some level of antioxidants, the concentration varies significantly. The fruits with deeper, richer colors, such as purple prunes and red goji berries, typically contain higher levels of the potent phenolic antioxidants and carotenoids. Lighter-colored dried fruits like apples may have some antioxidants but are generally less potent than their darker counterparts.
Do all drying methods affect antioxidant content equally?
Different drying methods can affect the final antioxidant content. For example, high-heat processes may cause more degradation of some heat-sensitive compounds. However, studies have shown that despite some reduction, the remaining phenolic antioxidants in dried fruits are often of high quality and retain significant health benefits.
How does ORAC value relate to antioxidant levels?
ORAC (Oxygen Radical Absorbance Capacity) is a method used to measure the total antioxidant capacity of foods. A higher ORAC value indicates a greater antioxidant power in a specific food. It's a useful comparison tool, but it's not the only indicator of a food's overall health benefits, which also include vitamins, minerals, and fiber.
Is it better to eat fresh or dried fruit for antioxidants?
Both fresh and dried fruits offer valuable antioxidants. Dried fruits provide a concentrated dose of antioxidants and fiber in a smaller, more portable package. Fresh fruits, however, contain higher levels of water-soluble vitamins like Vitamin C, which can be reduced during the drying process. A balanced approach incorporating both fresh and dried varieties is ideal for a comprehensive nutrient intake.
How much dried fruit should I eat to get antioxidants?
The recommended portion size for dried fruit is typically smaller than fresh fruit, often around a quarter-cup. Because dried fruit is calorically dense and higher in sugar, it's best consumed in moderation as part of a balanced diet. A small daily portion is enough to reap the benefits of its concentrated antioxidants.
Do added sugars in dried fruit reduce their health benefits?
Added sugars do not reduce the inherent antioxidant benefits of the fruit itself, but they significantly increase the calorie count and can negatively impact blood sugar levels. Many health-conscious individuals prefer unsweetened dried fruits to avoid the negative health effects associated with high sugar intake.
Is there a specific type of prune that has the highest antioxidants?
While specific varieties of plums may vary slightly in their antioxidant levels, prunes generally have a consistently high ORAC value. Research has not widely specified one variety as having significantly higher antioxidant content than others. For maximum antioxidant benefit, look for natural, unsweetened prunes.
Can dried fruits be part of a weight loss plan?
Yes, dried fruits can be part of a weight loss plan when consumed in moderation. Their high fiber content can increase feelings of fullness, and their natural sugars can satisfy cravings for sweets. However, their high calorie density means that portion control is crucial to avoid overconsumption and excess calorie intake.
Are sulfites in dried fruit harmful?
For most people, sulfites in dried fruit are harmless and help preserve the color and freshness. However, some individuals with sulfite sensitivity may experience reactions like stomach cramps, skin rashes, or asthma attacks. Those sensitive to sulfites should look for naturally brown or gray-colored dried fruits, which indicate the absence of sulfite preservatives.
Are dried fruits and trail mix the same thing?
No, dried fruits are a single ingredient product (e.g., raisins), whereas trail mix is a combination of various ingredients, often including dried fruits, nuts, and seeds. When purchasing trail mix, it's important to be mindful of added ingredients like chocolate, yogurt coatings, or excessive salt, which can increase sugar and calorie content.
Does the color of dried fruit indicate its antioxidant level?
Generally, yes. The richer and darker the color of a dried fruit, the higher its concentration of certain antioxidant compounds, particularly polyphenols like anthocyanins, which give fruits like prunes and goji berries their deep hues. For example, brown or gray dried apricots without sulfites are often more potent in natural antioxidants than their brightly colored, sulfur-preserved counterparts.
