Octopus (Octopus vulgaris) - Nutritional & Physical Profile
This profile details the nutritional and physical properties of common octopus (Octopus vulgaris), primarily based on cooked preparations.
1. Nutritional Composition
1.1. Per 100g (Cooked, Moist Heat)
| Nutrient Group | Metric (Unit) | Value |
|---|---|---|
| Energy | Kilocalories (kcal) | 164 |
| Macros | Protein (g) | 29.8 |
| Total Fat (g) | 2.1 | |
| Carbohydrates (g) | 4.4 | |
| Fiber (g) | 0.0 | |
| Sugars (g) | 0.0 |
1.2. Per Standard Serving (85g / 3 oz, Cooked, Moist Heat)
| Nutrient Group | Metric (Unit) | Value |
|---|---|---|
| Energy | Kilocalories (kcal) | 139 |
| Macros | Protein (g) | 25.3 |
| Total Fat (g) | 1.8 | |
| Carbohydrates (g) | 3.7 | |

2. Key Micronutrients (Per 100g, Cooked)
- Vitamins:
- Vitamin B12: ~36.0 µg (1500% DV) - Exceptionally high.
- Vitamin B6: ~0.4 mg (24% DV)
- Niacin (B3): ~3.0 mg (19% DV)
- Riboflavin (B2): ~0.1 mg (8% DV)
- Minerals:
- Selenium: ~90.0 µg (164% DV) - Very high.
- Copper: ~0.9 mg (100% DV) - High.
- Iron: ~5.3 mg (29% DV)
- Phosphorus: ~360 mg (29% DV)
- Zinc: ~1.7 mg (15% DV)
- Potassium: ~490 mg (10% DV)
- Magnesium: ~50 mg (12% DV)
- Antioxidants:
- Taurine: A sulfur-containing amino acid with significant antioxidant properties, abundant in octopus tissue.
3. Functional Impact
- Glycemic Index (GI): Very Low (Estimated <10). Octopus is primarily protein, with negligible digestible carbohydrates.
- Glycemic Load (GL): Very Low (Estimated <1).
- Satiety Score: High. The high protein content and moderate fat contribute to prolonged satiety.
4. Physical Properties
- Density (Cooked): Approximately 1.1 g/cm³. This is an average for muscle tissue post-cooking.
- Volumetric Contraction (After Cooking): ~20-25%. Significant water loss and tissue shrinkage occur during cooking, leading to a noticeable reduction in physical volume, while density increases slightly.

Why Octopus Is Difficult to Track
Journal Entry - Dr. Aria Vance
Another dive into the deep. Octopus. Ah, the ocean's enigma, a creature of myth and undeniable gastronomic delight. My current research trajectory is less about its eight arms and more about its caloric count, specifically how ludicrously difficult it is for the average human, bless their diligent little hearts, to track.
Historically, octopus has been a staple in coastal diets for millennia. Think Minoan frescoes, ancient Greek amphorae depicting fishermen, all clamoring for this cephalopod. The Mediterranean, East Asia – they've long understood its appeal. It’s lean, it’s protein-rich, it's exotic without being inaccessible. But the sheer variability! You get it grilled, stewed, carpaccio-style, braised into submission in red wine. Each preparation a unique beast.
And that, dear reader, is the rub for manual tracking. Try to log a serving of "pulpo a la gallega" using a generic barcode. Ha! A fool's errand. You might as well try to nail jelly to a tree. The potato content, the olive oil drench, the paprika dusting… it’s a symphony of variables. How much oil actually adheres to the octopus? How much broth was absorbed during braising versus simmered away? Scales are useless here, measuring only the composite mass, not the constituent nutritional density. A cup? Don't even get me started on the void spaces inherent in chunky, irregularly shaped seafood.
The sheer perplexity of its structure—all those writhing, delicious tentacles—makes portion estimation a nightmare. Is that a large tentacle? A small one? Is it from a giant Pacific octopus or a tiny common octopod? These distinctions matter when you're talking about precise protein intake. People don't want ballpark figures for their macros. They want precision. They need it, especially those managing specific dietary protocols. They're struggling, these poor souls, trying to eyeball their dinner plate, squinting at a restaurant dish, comparing it to a generic USDA entry that barely scratches the surface. It's frustrating. It's inefficient. It leads to compliance fatigue faster than you can say "tentacle."
This is why NutriSnap isn't just a convenience; it's a necessity. It’s the forensic nutritionist we didn't know we needed. A quick snap, and the AI, with its uncanny visual acumen, breaks down the octopus—its perceived preparation method, its likely portion size relative to other plate items, even inferring the added fats and starches that complicate manual logging. Finally, a solution that understands the inherent chaos of real-world dining. It sees the octopus, not just as a blob of protein, but as the complex, beautifully challenging food item it truly is. And it calculates accordingly. Pure genius.
