| Metric | Per 100g | Per Standard Serving (1 cup chopped, ~124g) |
|---|---|---|
| Calories | 17 kcal | 21 kcal |
| Protein | 1.21 g | 1.50 g |
| Carbohydrates | 3.11 g | 3.86 g |

Key Micronutrients (Per 100g, Raw Zucchini)
- Vitamins:
- Vitamin C: 17.9 mg (20% DV)
- Vitamin K: 4.6 µg (4% DV)
- Vitamin B6 (Pyridoxine): 0.16 mg (9% DV)
- Folate (B9): 24 µg (6% DV)
- Riboflavin (B2): 0.12 mg (9% DV)
- Minerals:
- Manganese: 0.17 mg (7% DV)
- Potassium: 261 mg (6% DV)
- Magnesium: 18 mg (4% DV)
- Phosphorus: 38 mg (3% DV)
- Antioxidants:
- Lutein + Zeaxanthin: 2120 µg
- Beta-carotene: Present in notable amounts (contributes to Vitamin A activity)
Functional Impact
- Glycemic Index (GI): Very Low (estimated < 15)
- Glycemic Load (GL) per serving: Very Low (estimated < 1)
- Satiety Score: High, due to significant water content (approx. 95%) and dietary fiber. Contributes to feelings of fullness with minimal caloric intake.
Physical Properties
- Density (Raw, whole): Approximately 0.98 g/cm³
- Volumetric Contraction (after cooking): Significant. Depending on cooking method (e.g., sautéing, roasting), zucchini can experience 60-75% volumetric contraction due to water evaporation, profoundly altering its perceived quantity and caloric density per unit volume.

The Manual Tracking Problem with Zucchini
Zucchini. A culinary chameleon. It slips, literally, through the cracks of conventional nutritional tracking, making accurate logging a statistical nightmare for the conscientious eater. This humble member of the Cucurbita pepo family, often relegated to supporting roles or the dreaded 'zucchini bread' glut of late summer, presents a profound challenge to precise nutritional tracking, defying our most earnest attempts at quantification with its inherent slipperiness.
Native to the Americas, domesticated thousands of years ago, but truly refined into its modern slender form in Italy – hence the "zucchini" (little squash) versus the British "courgette" – its very history is one of transformation. From a chunky, tough-skinned wild gourd to the delicate, water-rich vegetable we adore today. This journey, however, bequeathed it a core trait that utterly frustrates our data collection efforts: its incredible variability.
Imagine scooping "a cup" of raw, freshly grated zucchini. Now, hold that thought. Imagine that exact same quantity, sautéed down to a mere whisper in the pan, a shadow of its former self. The volumetric contraction is astounding; it’s like trying to measure a hydrated phantom. A cup of raw, dense zucchini is vastly different in weight, and therefore in macro distribution, from a cup of cooked, condensed zucchini. Who measures their zucchini before and after cooking, accounting for water loss? Nobody. And who has the patience? It’s a fool's errand.
This isn't just about water; it's about the transformation. Barcodes? On a whole, garden-fresh squash? Unlikely. Scales are a godsend, yes, but who honestly weighs every ingredient for every single dish, especially when it's a component of a larger, more complex meal? Do you weigh it whole? Peeled? Seeded? Chopped? Each step introduces potential error, each step multiplies the tedium. Manual tracking becomes an exercise in approximation, a grand guessing game where accuracy is the first casualty. We think we're eating "a serving," but what is a serving when the food itself is a shape-shifter on the plate? This pervasive inconsistency leads to skewed dietary records, undermining the very purpose of nutritional analysis.
That's precisely why our work at NutriSnap is crucial. No more guessing. No more wrestling with fluid ounces and phantom densities. Just a photo, and our forensic visual AI does the heavy lifting, providing granular insight where manual methods utterly fail. It's time to bring precision to the plate. Even for the most elusive of vegetables.
