Blackberry
Blackberry is a dark purple berry rich in fiber, vitamin C, and polyphenolic compounds. It is commonly consumed fresh, frozen, or in processed foods and has a modest nutrient density relevant to digestive and antioxidant intake.
Also known as: Rubus species berry, Bramble berry

Blackberries are the aggregate fruit of Rubus species plants native to Europe, northwestern Africa, and western Asia, now cultivated widely in North America and Europe. They are consumed fresh, frozen, dried, or incorporated into jams, juices, yogurts, and baked goods. Blackberries have a tart-to-sweet flavor profile and are available year-round in most markets in frozen form, with peak fresh availability in late summer.
A 100 g serving of raw blackberries provides approximately 43 calories, 9.6 g total carbohydrate (of which approximately 4.9 g are naturally occurring sugars), 5.3 g fiber, 1.4 g protein, and negligible fat. Blackberries are a source of vitamin C (21 mg per 100 g), vitamin K, and manganese. They contain substantial polyphenol content, particularly anthocyanins and ellagic acid. The high fiber content supports colonic bulk and may influence short-chain fatty acid production via fermentation by gut microbiota. At typical fresh serving sizes (around 65 g), blackberries are considered low-FODMAP by Monash University, making them suitable for individuals following a low-FODMAP diet.
Antioxidant and Polyphenol Content
Blackberries are among the more polyphenol-dense commonly consumed fruits. The anthocyanins and ellagic acid present have been documented in in vitro and animal models to possess free-radical scavenging properties and to modulate inflammatory pathways. Human clinical trials examining blackberry consumption and systemic inflammation, endothelial function, or oxidative stress markers remain limited in number and effect size. Current evidence supports blackberries as a polyphenol-dense food within a varied diet but does not establish specific disease-prevention claims.
Portion and Tolerance Considerations
Blackberries are well tolerated by most populations at typical consumption levels (100–150 g fresh per serving). They are low in natural amines and histamine, so they are not a typical trigger for migraine or histamine-sensitive individuals. The seed material may irritate some individuals with sensitive digestive tracts, particularly in concentrated or dried forms. No established upper limit exists. Whole blackberries contribute whole fruit fiber and minimal added sugar when consumed fresh or frozen without added sweeteners; processed blackberry products (jams, syrups) typically contain added sugars and should be evaluated per product label.
Frequently Asked Questions
Are blackberries high in sugar?
Fresh or frozen blackberries without added sweeteners contain approximately 9.6 g total carbohydrate per 100 g, of which about 4.9 g are naturally occurring sugars — modest compared to many other fruits. Processed blackberry products (jams, syrups, fruit drinks) typically contain added sugars and should be evaluated individually on the nutrition label.
Can people with IBS or FODMAP sensitivity eat blackberries?
Yes, in typical portions. Monash University rates fresh blackberries as low-FODMAP at approximately 65 g per serving. Larger portions or concentrated dried forms may be higher in FODMAPs; check the Monash FODMAP app for current guidance on specific serving sizes. The seeds may also cause discomfort in some individuals with sensitive digestive tracts.
Do blackberries have any specific health benefits?
Blackberries are nutrient-dense, providing fiber, vitamin C, vitamin K, and polyphenolic compounds including anthocyanins. In vitro studies show antioxidant activity, but human clinical trials demonstrating specific disease prevention or treatment effects remain limited. Blackberries are best viewed as one nutritious whole fruit choice within a varied diet.
