Cranberry (Vaccinium macrocarpon): Nutritional and Physical Profile
1.0 General Nutritional Profile (per 100g raw, fresh cranberries)
- Energy: 46 kcal (192 kJ)
- Macronutrients:
- Protein: 0.4 g
- Total Carbohydrates: 12.2 g
- Dietary Fiber: 4.6 g
- Total Sugars: 4.3 g
- Total Fat: 0.1 g
- Saturated Fat: < 0.01 g
- Monounsaturated Fat: < 0.01 g
- Polyunsaturated Fat: < 0.01 g
- Water Content: 87.1 g
1.1 Standard Serving Nutritional Profile (55g, approximately 1/2 cup raw, fresh)
- Energy: 25 kcal (106 kJ)
- Macronutrients:
- Protein: 0.2 g
- Total Carbohydrates: 6.7 g
- Dietary Fiber: 2.5 g
- Total Sugars: 2.4 g
- Total Fat: < 0.05 g
1.2 Key Micronutrients (per 100g raw, fresh)
- Vitamins:
- Vitamin C (Ascorbic Acid): 14 mg (16% DV)
- Vitamin E (alpha-tocopherol): 1.2 mg (8% DV)
- Vitamin K1 (phylloquinone): 5.1 µg (4% DV)
- Minerals:
- Manganese: 0.1 mg (4% DV)
- Copper: 0.06 mg (7% DV)
- Antioxidants & Phytonutrients:
- Proanthocyanidins (PACs): Significant amounts (Type A PACs are unique to cranberries, supporting urinary tract health).
- Anthocyanins: Responsible for red color, potent antioxidant activity.
- Quercetin: Flavonoid with anti-inflammatory properties.
- Ursolic Acid: Triterpenoid with potential health benefits.
1.3 Functional Impact
- Glycemic Index (GI): Low (estimated 45-50 for raw cranberries).
- Glycemic Load (GL): Very Low (estimated ~2-3 per 100g due to high fiber and low digestible sugar).
- Satiety Score: Moderate to High due to high fiber content, which contributes to fullness and slower digestion.
1.4 Physical Properties
- Density (g/cm³): Approximately 0.75 - 0.85 g/cm³ for whole, fresh cranberries (explains why they float).
- Volumetric Contraction After Cooking: Significant. When processed into sauces or compotes, whole cranberries can experience a volumetric reduction of 30-50% as cell walls rupture and water evaporates.

Why Cranberry Is Difficult to Track
Dr. Aria Vance, Lead Nutrition Data Scientist, NutriSnap.
The cranberry. A deceptively complex little orb. People assume it’s just… a berry. Raw. Simple. They’re wrong. Utterly, fundamentally wrong. We’re talking ancient superfood, a pillar of indigenous diets, historically revered for its tart punch and medicinal prowess. From the Wampanoag people, who called them "ibimi" or "bitter berry," using them in pemmican, dyes, and poultices, to their quintessential role at modern Thanksgiving tables, these ruby jewels have stories. Centuries of human interaction. A rich tapestry.
But for the love of all that is nutritionally sound, try tracking them manually. It’s an exercise in futility. A Sisyphean task. You buy a bag of fresh cranberries. Great. You scoop out a "half-cup." Is that a packed half-cup? Loose? Are they large, plump beauties, or shriveled runts? The density varies! Remember those tiny air pockets? They bounce. "Bounceberry" for a reason. Volume measurements? A farce. You need to weigh them. Always. But who whips out a scale for their morning smoothie’s handful of berries? Nobody.
Then the processing begins. Oh, the processing! Cranberry juice. A whole other beast. Often swimming in added sugars, stripped of its fiber, a pale echo of the whole fruit. Dried cranberries? Sweetened. Plumped with high fructose corn syrup or cane sugar. The caloric density skyrockets. It becomes more candy than fruit. Then there's the sauce. Grandma's special recipe. Is it mostly cranberries? Or mostly sugar and water, with a few sorry lumps of fruit floating in a gelatinous, sugary sea? The variability is immense. A truly terrifying spectrum. One person's "cranberry sauce" is a nutrient bomb; another's is a dessert. How do you log that? With a barcode scanner? Please. Most homemade dishes don't come with a neat little UPC label.
And the cultural context doesn't help. A tablespoon of cranberry sauce? A ladleful? Is it the jiggling cylinder from a can or a chunky, homemade relish? Each permutation wildly alters the actual nutrient intake. This isn’t a pre-portioned protein bar. This is a culinary chameleon. The sheer behavioral guesswork required to log "cranberries" accurately is enough to drive any data scientist to despair. It forces users into gross approximations, or worse, gives up. The human element, the sheer tedium, is the enemy of precision.
This is precisely why NutriSnap exists. Why we pour forensic levels of visual analysis into every single pixel. Our AI doesn't just see "red berry." It discerns texture, size distribution, residual liquid, contextual presentation. It learns the subtle cues of fresh vs. dried, sweetened vs. unsweetened, sauce vs. raw. It measures volume from multiple angles. It differentiates the homemade from the store-bought. It sees the complexity. Finally, an accurate record, simply from a photo. We’re not just tracking food; we’re understanding its nuanced journey from the bog to the plate.
