Winner

Salmon

82/ 100

Salmon wins on nutritional density especially omega-3s, but haddock is the smarter pick when you want lean protein with fewer calories and lower contaminant risk.

Salmon scores notably higher due to its exceptional omega-3 content, vitamin D, and anti-inflammatory benefits that are hard to replicate from other foods. Haddock remains a solid lean protein choice but lacks the standout nutritional advantages that make salmon a top-tier health food.

Salmon delivers powerful anti-inflammatory fats and vitamin D that haddock simply cannot match, but haddock gives you more protein per calorie and a cleaner safety profile at a lower price.

  1. Dimension 1 · Priority 97

    Omega-3 Fatty Acids

    Salmon
    Haddock · 12Salmon · 95

    Salmon delivers roughly 10-15x more omega-3s than haddock, making it one of the best dietary sources available.

    Tradeoff

    You get extraordinary anti-inflammatory benefits from salmon but take on more calories and fat to get them.

    Why it matters

    Omega-3s support heart health, brain function, mood stability, and joint comfort — benefits most people do not get enough of.

    Real-world impact

    Eating salmon twice weekly can meaningfully improve omega-3 levels within weeks, while haddock barely moves the needle.

    Haddock

      Better for

    • Low-fat diet followers

  2. Dimension 2 · Priority 85

    Protein Quality and Density

    Haddock
    Haddock · 88Salmon · 80

    Haddock provides more protein per calorie since it carries almost no fat, making it extremely protein-efficient.

    Tradeoff

    Haddock gives leaner protein but salmon's protein comes packaged with health-promoting fats that enhance nutrient absorption.

    Why it matters

    If you are tracking calories and maximizing protein intake, haddock lets you eat more volume for fewer calories.

    Real-world impact

    A 6oz haddock fillet delivers similar protein to salmon but saves you 100+ calories — useful for cutting phases or portion control.

    Haddock

      Better for

    • Calorie counters
    • Cutting-phase athletes
    • High-protein low-fat meal planners

      Worse for

    • Those needing calorie density for energy

    Salmon

      Better for

    • Those who benefit from fat-soluble vitamin absorption
    • Endurance athletes needing calorie density

      Worse for

    • Strict calorie restrictors
  3. Dimension 3 · Priority 82

    Vitamin and Mineral Density

    Salmon
    Haddock · 55Salmon · 90

    Salmon is significantly richer in vitamin D, B12, selenium, and astaxanthin — a unique antioxidant that gives salmon its color.

    Tradeoff

    Haddock provides decent B vitamins and selenium but cannot compete with salmon's exceptional micronutrient profile.

    Why it matters

    Vitamin D deficiency is widespread and salmon is one of the few natural food sources that provides meaningful amounts.

    Real-world impact

    One salmon serving can provide your full daily vitamin D target, while haddock contributes almost none.

    Haddock

      Better for

    • Those getting vitamin D from supplements or sun exposure already

      Worse for

    • Those depending on food for vitamin D

    Salmon

      Better for

    • Anyone with low vitamin D levels
    • People in northern climates with limited sunlight
    • Older adults at risk for B12 deficiency
  4. Dimension 4 · Priority 80

    Contaminant and Safety Profile

    Haddock
    Haddock · 82Salmon · 62

    Haddock generally carries lower contaminant levels than farmed salmon, which can contain PCBs, dioxins, and antibiotic residues.

    Tradeoff

    Wild salmon has a cleaner safety profile but costs significantly more, while farmed salmon is more accessible but riskier.

    Why it matters

    Regular consumption of contaminated fish can undermine the very health benefits you are eating it for.

    Real-world impact

    Choosing haddock or wild salmon reduces long-term contaminant exposure compared to regularly eating farmed salmon.

    Haddock

      Better for

    • Frequent fish eaters minimizing cumulative exposure
    • Parents feeding fish to young children
    • Those who cannot afford or source wild salmon consistently

    Salmon

      Better for

    • Those with access to wild-caught salmon
    • Occasional fish eaters for whom contaminant load is minimal

      Worse for

    • Regular consumers of farmed salmon accumulating PCBs over time
  5. Dimension 5 · Priority 72

    Satiety and Meal Satisfaction

    Salmon
    Haddock · 60Salmon · 85

    Salmon's healthy fat content makes meals more filling and satisfying, reducing the urge to snack afterward.

    Tradeoff

    Haddock leaves you lighter but hungrier sooner unless you pair it with other filling foods like whole grains or avocado.

    Why it matters

    Meals that actually satisfy you prevent overeating later, which matters more than calorie counts alone.

    Real-world impact

    A salmon dinner tends to carry you through the evening comfortably; haddock may leave you reaching for a snack by 9pm.

    Haddock

      Better for

    • Those preferring light meals
    • Small appetite individuals

      Worse for

    • Those who find lean fish unsatisfying alone

    Salmon

      Better for

    • Big eaters needing lasting fullness
    • Anyone prone to evening snacking
    • People eating one main meal per day

      Worse for

    • People who feel sluggish after rich meals
  6. Dimension 6 · Priority 70

    Budget and Accessibility

    Haddock
    Haddock · 85Salmon · 50

    Haddock is consistently cheaper and widely available frozen, while salmon — especially wild-caught — can be expensive and harder to find.

    Tradeoff

    Paying more for salmon buys you superior nutrition, but haddock makes regular fish consumption financially realistic.

    Why it matters

    The healthiest food only works if you can afford to eat it consistently.

    Real-world impact

    Haddock can often be found for half the price of salmon, making it easier to include fish in your weekly grocery budget.

    Haddock

      Better for

    • Families on tight grocery budgets
    • Meal preppers buying in bulk
    • Those living where fresh salmon is unavailable

    Salmon

      Better for

    • Those who can afford premium protein choices
    • People prioritizing nutrition over cost

      Worse for

    • Budget-constrained households
  7. Dimension 7 · Priority 60

    Flavor Versatility and Ease of Cooking

    It depends
    Haddock · 75Salmon · 75

    Haddock's mild flavor adapts to any seasoning or cuisine while salmon's richness stands on its own but is more polarizing.

    Tradeoff

    Haddock is more versatile for picky eaters and diverse recipes; salmon is easier to prepare simply and still taste great.

    Why it matters

    A fish you actually enjoy eating consistently beats a nutritionally superior one that sits in your freezer.

    Real-world impact

    Haddock disappears into fish tacos, chowders, and bakes without complaint; salmon needs fewer embellishments but not everyone loves its intensity.

    Haddock

      Better for

    • Picky eaters and kids
    • Cooks wanting a blank canvas for bold flavors
    • Fish taco and chowder recipes

      Worse for

  • PCB and dioxin contamination in farmed salmon

    medium

    Farmed salmon can contain elevated PCBs and dioxins from feed. Wild salmon has significantly lower levels.

  • Antibiotic residues in farmed salmon

    medium

    Some farmed salmon operations use antibiotics, which may contribute to resistance. Wild salmon avoids this concern.

  • Mercury exposure

    low

    Salmon is generally a low-mercury fish, though slightly higher than haddock. Safe for regular consumption.

Who wins for whom

Audience fit

Same foods, different winners depending on your goal.

  • children

    Haddock

    Haddock's lower contaminant load and milder flavor make it a safer, more kid-friendly introduction to fish.

  • daily consumption

    It depends

    Haddock is safer for daily eating due to lower contaminant risk, but salmon provides more nutritional value per serving — ideal is rotating both.

  • diabetes

    Salmon

    Salmon's healthy fats slow digestion and stabilize blood sugar more effectively than lean haddock alone.

  • elderly

    Salmon

    Salmon's omega-3s and vitamin D directly address age-related concerns like cognitive decline, inflammation, and bone health.

  • muscle gain

    Salmon

    Salmon provides quality protein alongside anti-inflammatory omega-3s that support recovery, making it slightly better for training adaptation.

  • weight loss

    Haddock

    Haddock's lower calorie density lets you eat generous portions while staying in a deficit, though salmon's satiety can also prevent overeating.

Your move

Decision guide

Choose Haddock

  • You are counting calories and want maximum protein with minimal fat
  • You eat fish several times weekly and want to limit contaminant exposure
  • You are feeding kids or picky eaters who prefer mild flavors
  • Wild salmon is unavailable and you want to avoid farmed salmon risks
  • Your grocery budget needs a more affordable fish option

Choose Salmon

  • Heart and brain health are top priorities for you
  • You eat fish only once or twice a week and want maximum nutritional impact
  • You have low vitamin D levels or limited sun exposure
  • You can access and afford wild-caught salmon
  • You want a single fish serving that keeps you full for hours

Either works if

  • You simply want a clean protein source and are not focused on omega-3s
  • You are already taking fish oil or omega-3 supplements
  • You rotate proteins throughout the week and both fit your meal plan

Avoid both if

  • You have a fish or seafood allergy
  • You are following a strict plant-based diet
  • You have severe gout and need to limit all purine-rich foods

Final recommendation

Eat salmon when you can get wild-caught — its omega-3 and vitamin D benefits are genuinely hard to beat. Choose haddock when you need a leaner, cheaper, lower-contaminant option or just want a lighter meal. The smartest approach is rotating both: salmon twice a week for the fats your brain and heart need, haddock on other days for lean protein without the price tag or contaminant concerns.

Practical

Consumer tips

  1. 1

    Choose wild-caught salmon when possible — it has fewer contaminants and more omega-3s than farmed

  2. 2

    If buying farmed salmon, look for certifications like ASC or responsible farming labels

  3. 3

    Frozen haddock is often fresher than 'fresh' fish that has been sitting on ice for days

  4. 4

    Bake or poach both fish rather than frying to preserve omega-3s and avoid adding unhealthy fats

  5. 5

    Pair haddock with avocado or olive oil to compensate for its lack of healthy fats

  6. 6

    Check Seafood Watch for sustainability ratings before buying either fish

  7. 7

    Avoid salmon with added colorants — wild salmon gets its color naturally from astaxanthin
