Squid (calamari is the Italian/Spanish word, often used for cooked squid) is cephalopod widely eaten in Mediterranean, Asian, South American cuisines. Per 3 oz raw or grilled (85 g) – 75 calories, 2 g carbohydrate (slight; carb-free preparation method dependent), 13 g protein, 1 g fat (less than 1 g saturated), 38 mg sodium (low). Per 3 oz fried (breaded calamari) – 195 calories, 13 g carbohydrate, 13 g protein, 12 g fat, 65 mg cholesterol, 215 mg sodium. Big difference between preparations – plain squid is diabetes-friendly; fried calamari adds significant carbs and oil. Plain glycemic impact – minimal. Benefits – high quality protein; very low fat; very lean (plain preparations); rich in nutrients – selenium (60% DV per 3 oz), B12 (50% DV), copper, iron, magnesium, phosphorus, riboflavin. Affordable seafood option ($5-15/lb). Concerns – cholesterol higher than fish (220 mg per 3 oz – high); preparation method critical (fried adds carbs and saturated fat); allergy potential (shellfish family); sustainability variable. Multiple preparations with different diabetes implications. Diabetes-friendly preparations – grilled squid (quick high heat with olive oil, lemon, garlic); sauteed squid (quick stir-fry in olive oil with garlic, white wine, tomatoes – Mediterranean style); squid salad (cooked squid rings cooled in salad with celery, lemon, olive oil, herbs); stuffed squid (filled with vegetables/seafood/herbs – small portion rice or breadcrumb if used); squid soup (zuppa di calamari) in tomato or seafood broth; squid ink pasta (very small portion pasta; protein-heavy sauce); squid sashimi; Korean squid stir-fry (watch sugar in sauces); Spanish-style squid (chipirones a la plancha); Mediterranean grilled with romesco sauce (small portion). Limit/avoid – fried calamari (breaded, deep-fried) adds 15+ g carbs and oil per serving; calamari rings with sweet dipping sauces (sweet chili, marinara with sugar); tempura calamari; sweet teriyaki preparations; heavy cream sauces. Squid cooks quickly (overcook = rubbery) – 1-2 minutes high heat OR 30+ minutes slow braise; nothing in between. Both squid and octopus are cephalopods with similar nutrition – octopus has more protein and calories; squid leaner per ounce. Squid generally less expensive ($5-15/lb vs $15-30/lb for octopus).

Two cooking principles – fast (1-2 minutes high heat) OR slow (30-60 minutes braising), nothing in between. Squid vs octopus – both cephalopods with similar nutrition; octopus has more protein and calories; squid leaner per ounce; squid cooks quickly while octopus needs tenderizing; squid generally less expensive ($5-15/lb vs $15-30/lb). Squid cholesterol higher than most fish (220 mg per 3 oz) – similar to shrimp; AHA no longer specifies daily cholesterol limit; saturated fat more important; squid’s very low saturated fat is positive. Most cardiologists comfortable with squid in moderate amounts as part of healthy diet. Available at seafood counters, Asian markets, Mediterranean specialty markets, Costco (frozen rings). Cost $5-15/lb. For adults with type 2 diabetes – squid is excellent lean protein source with very low carbs when prepared plain; grilled, sauteed, salad, and stuffed preparations are diabetes-friendly; limit fried calamari due to breading and oil; affordable and widely available seafood option.
