Pacific Halibut vs. Pacific Cod: Which Is Healthier?
Pacific halibut and Pacific cod are two of the most popular white fish on the West Coast — both mild, firm, and versatile in the kitchen. But when it comes to nutrition, they’re not identical. Here’s a complete side-by-side comparison to help you choose the right fish for your health goals.

Key Differences Explained
Protein
Both fish are essentially tied on protein — approximately 19g per 3 oz serving. Both provide all essential amino acids, making either an excellent choice for muscle building, recovery, and satiety.
Fat & Omega-3 Fatty Acids
This is where halibut pulls ahead. Pacific halibut contains roughly 2–3x more omega-3 fatty acids than cod (450mg vs. 200mg per serving). Omega-3s (EPA and DHA) support heart health, brain function, and reduce inflammation. Halibut’s higher fat content is almost entirely healthy unsaturated fat — not a concern for most diets.
Vitamins & Minerals
Halibut leads across the board on micronutrients:
- Vitamin D: Halibut provides 20% DV vs. cod’s 6% — a significant difference for bone health and immune function
- Vitamin B12: Halibut at 30% DV vs. cod at 20% DV — both solid, halibut edges ahead
- Selenium: Halibut at 50% DV vs. cod at 40% DV — both excellent antioxidant sources
- Niacin: Halibut at 35% DV vs. cod at 20% DV — important for energy metabolism
Mercury Levels
This is where cod has an advantage:
- Pacific Cod: FDA classifies as “Best Choice” — can be eaten 2–3 times per week safely by most adults, including pregnant women
- Pacific Halibut: FDA classifies as “Good Choice” — safe for most adults at 1 serving per week; pregnant women and young children should limit to 1 serving per week
Calories
Both are very low in calories — 94 for halibut vs. 89 for cod per 3 oz serving. The difference is negligible for most diets. Both are excellent choices for weight management.
Flavor & Texture Comparison
- Pacific Halibut: Mild, slightly sweet, firm and meaty with large flakes. Holds up well to grilling, searing, and baking. More forgiving to cook — stays moist even if slightly overcooked.
- Pacific Cod: Very mild, slightly briny, tender with smaller flakes. Excellent for fish and chips, chowder, and poaching. More delicate — can fall apart if overcooked.
Which Should You Choose?
- Choose halibut if: You want more omega-3s, vitamin D, and overall nutritional density; you’re cooking a premium dish where texture matters; or you’re grilling or searing
- Choose cod if: You want the lowest mercury option; you’re pregnant or feeding young children; you’re making chowder, fish tacos, or battered fish dishes; or you prefer a more budget-friendly option
- For overall nutrition: Halibut wins on omega-3s, vitamin D, and micronutrient density. Cod wins on mercury safety and affordability.
