The Core Nutritional Breakdown
When placed side-by-side, the basic nutritional stats for haddock and cod are remarkably similar, both providing lean protein with very low-fat content. However, a closer look reveals the subtle differences that can influence your choice depending on your dietary goals.
Haddock vs. Cod: At a Glance
| Nutrient (per 100g cooked) | Haddock | Cod |
|---|---|---|
| Calories | ~90 kcal | ~105 kcal |
| Protein | ~20g | ~22.8g |
| Total Fat | Very low | Very low |
| Sodium | Higher | Lower |
| Mercury Level | Lower | Low |
It is clear from this high-level view that both are excellent, lean protein sources. For instance, both fish provide essential amino acids needed for muscle repair and growth. The slight differences in calorie and fat content are generally insignificant for most healthy adults. However, the higher sodium content in haddock can be a deciding factor for those managing blood pressure.
Vitamins and Minerals: A Deeper Dive
The nutritional rivalry intensifies when examining the specific vitamins and minerals these fish provide. Neither is a clear winner, as each offers a unique mix of benefits.
Haddock is notable for:
- Vitamin B12: Essential for nerve function and red blood cell formation, haddock boasts a higher concentration.
- Phosphorus: Important for bones and energy metabolism, haddock contains a higher level.
- Selenium: A powerful antioxidant, both fish are good sources, but haddock can have a slight edge.
Cod provides more of:
- Vitamin D: Crucial for immune function and calcium absorption, cod is the better source, especially relevant during months with less sun exposure.
- Magnesium: An important mineral for nerve and muscle function, bone health, and blood pressure regulation.
- Potassium: Helps regulate blood pressure and fluid balance.
Another point of distinction for cod is its liver oil. Cod liver oil is a potent source of omega-3 fatty acids, along with vitamins A and D, offering significant benefits for heart health, brain function, and joint relief. While haddock does contain omega-3s, cod liver oil's concentration is a significant differentiator.
Mercury Levels and Sustainability
For those concerned about environmental impact and contaminants, these factors play a significant role. Haddock tends to be the better choice regarding mercury, while the sustainability of both depends heavily on sourcing.
Mercury Content
Fish accumulate mercury throughout their lives, so smaller, shorter-lived fish generally have lower levels. Since haddock is a smaller, slimmer fish than cod, it typically contains slightly less mercury. This is an important consideration for vulnerable populations, such as pregnant women or young children, and for those who consume fish frequently.
Sustainability
Both Atlantic cod and haddock fisheries are managed by authorities like the U.S. National Oceanic and Atmospheric Administration (NOAA) to prevent overfishing and support rebuilding efforts. However, stock levels and sustainability ratings can fluctuate based on location and time. For example, haddock stocks have faced recent challenges and are under tighter management in some regions. To make a truly sustainable choice, look for certification from reputable organizations like the Marine Stewardship Council (MSC) and check resources like the NOAA Fisheries website for the most current information.

Culinary Considerations: Taste and Texture
Beyond nutrition, personal taste and cooking method can be the ultimate deciding factors. While both are mild white fish, their textures differ.
- Cod: Known for its firm, flaky flesh that holds up well to cooking methods like baking, grilling, and pan-searing. It has a mild, clean flavor, making it incredibly versatile.
- Haddock: Features a finer, more delicate flake and a slightly sweeter taste. Its more fragile texture makes it excellent for frying, smoking, or poaching, where it won't be subject to rough handling.
Which is Healthier Haddock or Cod? The Final Verdict
Ultimately, deciding which is healthier, haddock or cod, depends on your specific health priorities. Both are outstanding, lean protein sources that offer a wealth of nutrients.
- Choose haddock if: you prioritize slightly lower mercury levels and higher concentrations of B vitamins.
- Choose cod if: you want more vitamin D, higher potassium, and access to beneficial cod liver oil.
For a balanced approach, incorporating both fish into your diet ensures a broader spectrum of nutrients. Always prioritize sustainably sourced fish, and select the one that best complements your recipe and taste preference. The health benefits of regular fish consumption far outweigh the minor nutritional variations between these two wonderful white fish.
