Key Micronutrients

Vitamin B12 (Cobalamin): 1.3 µg (54% DV) Vitamin B3 (Niacin): 2.1 mg (13% DV) Vitamin B6 (Pyridoxine): 0.05 mg (3% DV) Vitamin C (Ascorbic Acid): 4.7 mg (5% DV) 💎 Selenium: 44.8 µg (81% DV) 💎 Copper: 1.89 mg (210% DV) 💎 Phosphorus: 221 mg (18% DV) 💎 Zinc: 1.0 mg (9% DV) 💎 Iron: 0.6 mg (3% DV) 💎 Potassium: 235 mg (5% DV) 💎 Sodium: 37 mg (2% DV) 🛡️ Selenium (as part of selenoproteins) 🛡️ Taurine (amino acid, functions as an antioxidant and anti-inflammatory agent) [2]

Biochemical Impact

Glycemic Index (GI) Very Low (~15-20, estimated). Primarily protein and fat, negligible digestible carbohydrates. [3]
Glycemic Load (GL) Very Low (~1-2 per 85g serving, estimated).
Satiety Score High. High protein content contributes significantly to satiety, promoting fullness and reducing subsequent energy intake. [4]

Physical Volumetrics

Density: ~1.05 - 1.08 g/cm³ [5]
Volumetric Contraction/Expansion: Mass Reduction: 25-40% (due to water loss) [6]

Why Squid Is Difficult to Track

Field Notes - Dr. Aria Vance, Lead Nutrition Data Scientist at NutriSnap

Entry 703: Investigating Teuthida. Squid. Calamari. What a conundrum for accurate dietary tracking. It's truly maddening.

My desk is a graveyard of half-eaten calamari dishes. Fried rings. Grilled tubes. Stuffed. The sheer variability of this cephalopod on a plate is just... wild. Forget your neatly packaged cereal box with its uniform barcode. This isn't that. This is the untamed ocean, landing on your plate with a side of impossible-to-quantify culinary chaos.

Historically, squid was often considered a poor man's food, a readily available protein in coastal communities. Think Mediterranean fishing villages, or the bustling night markets of Southeast Asia, where it's transformed into everything from crispy fritters to delicate stir-fries. It became a delicacy, "calamari," in Western cuisine, and bam! suddenly everyone wants to eat it, but nobody can tell you what they're actually eating.

Try manually tracking this. Seriously, try it. You've got a plate of fried calamari. Rings, tentacles, maybe a lemon wedge. Your app asks, "How many grams?" I mean, come on. Do you pull out a scale at the restaurant? Do you eye-ball it? The problem isn't just the squid itself; it’s the preparation. The breading. Oh, the breading! It clings, it absorbs. How much oil did those golden-brown rings soak up? Is it a light dusting of semolina or a thick, beer-battered coating? These seemingly minor variations dramatically swing the caloric needle. One bite of fried squid versus a bite of simply grilled, un-oiled squid? Worlds apart. Entire galaxies.

Then there's the serving size illusion. One restaurant's "appetizer portion" might be twice another's. Is it 3 oz of actual squid, or 3 oz of squid plus breading plus absorbed oil? The human eye, bless its heart, is a terrible estimator. And don't even get me started on the sauces. Aioli. Marinara. Sweet chili. Each a caloric landslide that's almost always ignored in manual logging. The fundamental flaw with barcodes, measuring cups, and kitchen scales is their assumption of culinary uniformity. They assume you're eating a singular, pre-defined item. Squid is a shape-shifter. A chameleon. A nutritional enigma wrapped in a delicious, often greasy, coating.

This, this is precisely why we built NutriSnap. Manual tracking for something like squid isn't just tedious; it's fundamentally inaccurate. Our AI photo tracker doesn't just see a "squid ring"; it forensically analyzes the visual texture of the breading, estimates oil absorption based on translucency and sheen, differentiates between grilled char and residual sauce. It learns from millions of images, understanding the volumetric contraction upon cooking, factoring in the likely density changes. We don't just see food. We dissect it, pixel by pixel. It's the only way to truly understand what's on your plate.
