Radish (Raphanus sativus) - Nutritional Profile
Macronutrients & Calories
| Nutrient Category | Per 100g Raw Radish | Per Standard Serving (1 cup sliced, ~116g) |
|---|---|---|
| Calories (kcal) | 16 | 19 |
| Protein (g) | 0.68 | 0.79 |
| Carbohydrates (g) | 3.4 | 3.94 |
| Fiber (g) | 1.6 | 1.86 |
| Sugars (g) | 1.86 | 2.16 |
| Fat (g) | 0.1 | 0.12 |
Key Micronutrients (per 100g)
- Vitamins:
- Vitamin C: 14.8 mg (16% DV)
- Folate (B9): 29 µg (7% DV)
- Vitamin B6: 0.07 mg (4% DV)
- Minerals:
- Potassium: 233 mg (5% DV)
- Calcium: 25 mg (2% DV)
- Manganese: 0.035 mg (2% DV)
- Antioxidants & Phytochemicals:
- Anthocyanins (especially in red varieties)
- Isothiocyanates
- Glucosinolates
Functional Impact
- Glycemic Index (GI): Very Low (~15-20)
- Glycemic Load (GL) per serving: Extremely Low (~1-2)
- Satiety Score: Low due to high water content and low caloric density; however, fiber content contributes to digestive health and modest satiety.
Physical Properties
- Density: Approximately 0.98 g/cm³ (raw, typical red globe variety)
- Volumetric Contraction after Cooking: Negligible under typical raw consumption. For prolonged high-heat cooking (e.g., roasting), volume reduction can range from 10-15% due to water loss and structural collapse, though this is not a common preparation method.

The Elusive Radish: A Tracking Nightmare
Another day, another dietary data dive. Radishes. Tiny. Insignificant, right? Wrong. These humble roots, Raphanus sativus, have been vexing nutrition data scientists for millennia, or at least since we started caring about precise intake. The Egyptians munched on them, a staple for pyramid builders. Romans adored them, believing in their medicinal properties. From the spicy daikon in Japanese cuisine, a veritable behemoth, to the delicate French breakfast variety, elongated and subtly sweet, these are not just one vegetable; they're a lineage. A global tapestry of flavor. The initial crunch. That distinctive peppery snap, a kick from their unique isothiocyanates. Glorious.
But for data, oh, the data. Such a pain in the neck. Try tracking them. Go on. Get a cup. Is it thinly sliced? Thickly chopped? Whole, perhaps? A "cup" of whole radishes yields wildly different caloric and macro values than a cup of finely julienned ones. Volumetric measurement is a cruel jest here. Then there's the weight. You're going to weigh every single tiny, individual radish? Every cluster of three? When preparing a salad, are people really pulling out a scale for what amounts to a mere handful of these crimson gems? Absolutely not. No barcode to scan, obviously. No standard unit beyond the ethereal "a few." It's a nutritional ghost, appearing and disappearing from logs with frustrating imprecision. This constant, pervasive imprecision, for even the simplest, most fundamental food item, undermines the entire edifice of dietary tracking. It’s maddening.
It's this pervasive imprecision, this silent sabotage of data integrity, that makes traditional logging methods utterly archaic. People quit. They just do. Why bother, when accuracy feels like chasing smoke? The manual effort simply isn't proportional to the perceived value for items like radish. This is exactly why NutriSnap exists. A true game-changer. Our forensic visual analysis capabilities, driven by advanced AI, instantly recognize variety, estimate volume based on object recognition, and infer precise weight. Snap a pic. It’s done. Finally, the radish surrenders its secrets.
