Although black cod and cod both contain many nutrients, vitamins and minerals, you may have noticed one contains more than the other. This may answer the question many people ask about the two. Is black cod healthier than cod?

Black cod is healthier than cod due to its 700% more heart healthy omega-3 fatty acids. Black cod also contains more vitamins and minerals like B6, B12, B5, thiamin, riboflavin, niacin, iron, folate, magnesium, calcium and selenium.

Although, as most of us probably already know, cod is no slouch either. It contains more protein and less calories. Cod provides more potassium, phosphorus and zinc 7.

If counting calories is currently a main priority, black cod contains many more. You may want to consider a lower calorie side dish or choose the cod instead. It’s hard to argue against the greater number of nutrients in black cod for overall health.

Seafood is renowned for being a part of many diets like keto or heart healthy.

Black Cod and Cod Health Benefits

Omega-3 Fatty Acids

Looking at the nutritional information of black cod and cod above, you will notice black cod has more fat than cod. However, the fat is healthy. Some of the fat in both black cod and cod are omega-3 fatty acids, which our bodies can not produce on their own.

Why are omega-3 fatty acids so important to health? Omega-3 fatty acids are heart healthy and help keep cholesterol levels lower and arteries healthy. Two of the fatty acids, DHA and EPA are associated with lowering blood pressure and improving the health of blood vessels 8.

Black cod contains about eight times the amount of omega-3s than cod. This difference is what really separates the two and gives black cod the edge over cod.

B Vitamins

Black cod contains many more B vitamins than cod. These include B6, B12, B5, B1 (thiamin), B2 (riboflavin), B3 (niacin) and B9 (folate). These B vitamins helps support the following:

  • Red blood cells
  • Digestion
  • Brain function
  • Nerve function
  • energy levels
  • Cardiovascular health

Magnesium

Black cod almost provides twice the number of magnesium as cod. Adding magnesium to your diet could be instrumental in improving your sleep quality. More so, it helps keep blood pressure levels balanced and stable 9.

Magnesium relaxes and calms the whole body including the blood vessels. A recent study researched 22 studies and concluded magnesium supplementation decreased systolic blood pressure by 3-4 mm Hg and diastolic blood pressure by 2-3 mm Hg 10.

Calcium

Black cod contains twice the amount of calcium than cod. Calcium, like magnesium is important for blood pressure and the heart. Harvard Health reports calcium helps maintain blood pressure because it helps to control the relaxing and tightening of blood vessels 11.

Black Cod and Cod Tastes and Textures

Black cod has a rich buttery flavor. Due to the buttery flavor many people call it a butter fish. It’s very rich and has a silky texture. The buttery, silky texture is due to its high fat content. After one bite you’ll realize why people call it the butter fish.

Cod has a mild, milky flavor. Atlantic cod may be slightly sweeter than Pacific cod. Many people say the texture of cod is similar to chicken due to its firmness. Cod has large flakes and is good for various cooking methods.

Can You Substitute Cod for Black Cod?

Sometimes you won’t have the exact fish for a recipe, or the seafood section of the supermarket doesn’t have what you need. Therefore, can you substitute cod for black cod?

Black cod and cod can substitute for each other although their tastes and textures are different. Cod cannot cook as long as black cod because it will dry out quicker. Black cod can be cooked using the same methods as cod like roasting, poached, broiled or grilled.

What is a good substitute for cod? Good substitutes for cod include pollock, haddock, halibut, striped bass, tilapia and mahi mahi.

What is a good substitute for black cod? Good substitutions for black cod include salmon, white perch, herring, mackerel, rainbow trout, White Sea bass. When substituting one fish for the other always stick to the following:

  • Same size and weight.
  • Stick with similar fillets, whole fillet or cross section.
  • Stick with skinless or skin when the recipe calls for one.
  • Texture is more important for certain cooking methods. Like using a firmer texture when grilling 12.

Due to black cod’s high fat content, it’s very forgiving while cooking and it’s difficult to overcook it. Most fish will dry out right away when cooked too much, that won’t happen with black cod. Black cod can be cooked grilled, broiled, roasted, sautéed, poached or smoked 13.

Black Cod and Cod Mercury Levels

The U.S. Food and Drug Administration and the EPA have issued warnings and suggestions regarding mercury levels in fish and consuming them 14. This is especially important for pregnant women, breastfeeding or for young toddlers and infants.

They established a list of best and good choices of fish based on their mercury levels. They also have a third section which are choices to avoid because they have the highest mercury levels. Therefore does black cod or cod have more mercury?

Black cod has more mercury than cod. Cod is listed on the FDA’s best choices and black cod (sablefish) is listed as a good choice in regards to mercury levels. The FDA recommends eating cod no more than two servings a week and black cod once per week.

Always check with a physician prior to eating new foods or changing your dietary habits.
