Nutrition Facts
Per 100g

Diet Ratings

KetoApproved

Squid is a lean protein with minimal carbs (1g net carbs per 100g cooked). Low fat content means it should be paired with fat sources, but nutritionally compatible with keto macros.

VeganAvoid

Squid is a marine animal (cephalopod). Consuming it violates the core vegan principle of excluding all animal flesh. No ambiguity.

PaleoApproved

Squid is a marine cephalopod and unprocessed seafood, rich in protein and available to coastal hunter-gatherers. Contains no grains, legumes, or problematic additives when fresh or frozen without added ingredients.

MediterraneanApproved

Squid is a seafood staple in Mediterranean cuisine, particularly in Greek, Italian, Spanish, and Portuguese traditions. It is lean, protein-rich, and aligns perfectly with the recommendation to eat fish and seafood 2-3 times weekly. Squid is a traditional Mediterranean ingredient.

CarnivoreApproved

Seafood product, pure animal-derived protein and fat. Squid is a complete animal food with micronutrients including selenium, copper, and B vitamins. Minimally processed when fresh.

Whole30Approved

Squid is seafood, which is explicitly allowed on Whole30. It is a whole, unprocessed protein source.

Low-FODMAPApproved

Squid is a protein-based seafood with negligible FODMAP content. Contains no significant fructans, GOS, lactose, excess fructose, or polyols. Safe at standard serving sizes during elimination phase.

DASHCaution

Squid is a lean protein source rich in B vitamins and minerals, but contains moderate sodium (typically 250-350mg per 3oz cooked) and cholesterol. DASH emphasizes lean seafood, but squid's sodium and cholesterol content warrant moderation.

Debated

Updated DASH interpretations increasingly recognize that dietary cholesterol has minimal impact on blood cholesterol for most individuals (2020-2025 Dietary Guidelines), and squid's lean protein and micronutrient profile may warrant a higher rating in modern practice.

ZoneApproved

Squid (calamari) is a lean protein source with ~19g protein per 3 oz cooked serving, minimal carbs (~1g), and low fat (~1.5g). It fits cleanly into Zone protein blocks and is an excellent low-glycemic protein choice. Slightly higher in cholesterol than white fish but still favorable for Zone.

Squid is a lean protein with some omega-3 content, but also contains arachidonic acid (pro-inflammatory in excess). It is lower in omega-3s than fatty fish. Acceptable in moderation as part of a varied protein intake, but not a primary anti-inflammatory protein source.

Debated

Some anti-inflammatory frameworks emphasize squid's selenium and B vitamins as beneficial; others flag arachidonic acid as problematic for those with autoimmune conditions or high baseline inflammation.

Squid is high in protein (15-20g per 3oz) and low in fat when prepared simply, but has a chewy, dense texture that may be difficult to digest given GLP-1-induced slowed gastric emptying. Fried squid is high-fat and should be avoided. Grilled or steamed squid is acceptable but requires careful chewing and may cause discomfort.

Debated

Some clinicians recommend squid as a lean protein source; others suggest avoiding it during early GLP-1 treatment due to texture-related digestive strain, particularly if patients experience nausea or early satiety.
