Raspberry
Raspberry is a soft berry rich in fiber, vitamin C, and polyphenols, commonly consumed fresh or in processed forms. It has a modest glycemic impact and contains compounds with antioxidant properties.
Also known as: Red raspberry, Black raspberry, Rubus idaeus, Rubus occidentalis

Raspberry (Rubus species) is a small, aggregate fruit composed of many drupelets clustered around a central core. Red, black, and golden varieties are commercially available. Raspberries are consumed fresh, frozen, dried, or processed into jams, juices, and supplements. They originate from temperate regions across the Northern Hemisphere and are a staple in desserts, smoothies, and baked goods.
A 100 g serving of fresh red raspberries contains approximately 52 calories, 11.9 g total carbohydrate, 6.5 g fiber, and 1.2 g protein. Raspberries are a notable source of vitamin C (approximately 29% of daily value), manganese, and polyphenolic compounds including ellagic acid and anthocyanins. The relatively high fiber content and low digestibility of some polyphenols mean raspberries have minimal impact on blood glucose. Raspberry fiber reaches the colon largely intact, providing substrate for beneficial bacteria.
Blood Sugar and Glycemic Response
Raspberries have a low glycemic index due to their high fiber content and modest sugar load. A standard 150 g serving contains approximately 7–8 g net carbohydrate (total carbohydrate minus fiber), resulting in minimal blood glucose elevation in people without diabetes. The polyphenols in raspberries, particularly anthocyanins, do not significantly alter glucose absorption in humans, though in vitro evidence suggests potential for alpha-glucosidase inhibition.
Tolerance and Intake Guidance
Raspberries are well tolerated by most people in typical culinary portions (100–200 g fresh or equivalent frozen). The high fiber content may cause temporary bloating or loose stools if intake increases sharply; gradual introduction is advisable for those with sensitive digestion. Raspberries are not a common allergen, though oral allergy syndrome (OAS) can occur in individuals with birch pollen allergy. Pesticide residues are occasionally detected on conventionally grown raspberries; washing is standard practice. No specific toxicity or contraindication exists for typical consumers.
Frequently Asked Questions
Are raspberries high in sugar?
Raspberries contain approximately 4–5 g of sugar per 100 g fresh fruit, which is low. Their high fiber content (6.5 g per 100 g) means a large proportion of total carbohydrates are indigestible, resulting in minimal blood glucose impact in people without diabetes.
Can raspberries cause digestive issues?
Raspberries are well tolerated in typical portions. The high fiber may cause temporary bloating or loose stools if intake increases abruptly; gradual introduction is recommended for those with sensitive digestion.
Are raspberries a common allergen?
Raspberries are not a major food allergen. Oral allergy syndrome (OAS) can occur in individuals with birch pollen allergy due to cross-reactivity with raspberry proteins, typically causing mild itching in the mouth. Cooking or processing raspberries generally eliminates this reaction.
