Both fish contain a wide variety of similar nutrients. Cod contains more of some nutrients while sea bass contains more of others. Therefore, is sea bass healthier than cod?

Sea bass is healthier than cod due to its higher percentage of heart healthy omega-3 fatty acids and B vitamins. Sea bass provides more B6, thiamin, riboflavin, B5, magnesium and selenium. 

As everyone knows cod is no slouch and offers a wide variety of nutrients as well. Cod provides a higher percentage of B12, niacin, folate, potassium and calcium. Cod and sea bass contain similar amounts of zinc, phosphorus, iron, cholesterol and protein.

It’s difficult to argue against cod but the main difference between the two fish is the number of omega-3 fatty acids. Sea bass provides over three times more than cod. Keep reading, and the next section explains why omega-3s are important.

Sea bass and Cod Health Benefits

Omega 3 Fatty Acids

Sea bass provides 0.76 grams and cod 0.22 grams per four ounces raw. Sea bass contains over three times the amount which leads to the question, why does omega-3 fatty acids matter so much?

It’s because omega-3 fatty acids are heart healthy and help keep arteries healthy. One way they accomplish this is by keeping bad cholesterol low and good cholesterol high.

Two of the fatty acids, DHA and EPA are associated with lowering blood pressure and improving the health of blood vessels 3.

In addition, they help keep the blood vessels healthy by reducing inflammation, plaque build-up, triglycerides and can help keep the heart rhythms more normal.

Studies suggest omega-3s can help reduce joint pain and stiffness in people with rheumatoid arthritis. They may also boost the effectiveness of anti-inflammatory drugs.

B Vitamins

Of the seven B vitamins listed in the table above, sea bass contained a higher percentage of four of them. The B vitamins in the table include B6, B12, B5, B1 (thiamin), B2 (riboflavin), B3 (niacin) and B9 (folate). B vitamins help support the following:

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


Sea bass and cod provide magnesium 4. Adding magnesium to your diet could be instrumental in improving sleep related issues like insomnia. Magnesium relaxes and calms the whole body including the blood vessels 5.

More so, it helps keep blood pressure levels balanced and stable. A recent study researched 22 studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 6.

Magnesium helps control muscle and nerve function, blood sugar and blood pressure. In the muscles and heart, magnesium competes with calcium to help the muscles relax after contracting.

When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat.


Sea bass and cod contain good amounts of selenium. Studies 7 show selenium may help to protect the following:

  • Immune system
  • Heart disease
  • Cognitive issues
  • Thyroid health


Cod and sea bass provide a good amount of calcium. Like magnesium, calcium 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 8.


Cod contains almost 500 mg of potassium while sea bass has 290 mg. Potassium is beneficial for reducing sodium intake. It helps the body reduce fluids and rids excess sodium 9. This process helps to reduce blood pressure.

Sea Bass and Cod: Tastes and Textures

One of the most important things people takes into consideration when choosing a fish is its taste. When comparing the two fish, does sea bass taste like cod?

See bass and cod have a mild to sweet taste but sea bass is sweeter. Cod tastes more buttery and is a little more tender than the meatier sea bass.

Sea bass has a mildly sweet flavor and is one of the most flavorful fish. For people who don’t prefer a fishy smell or taste, sea bass is a good choice. Sea bass is medium-firm but flaky and oily. 

Cod has a non-fishy mild taste. The mild taste can be sweet at times and is good for people who don’t like a fishy tasting seafood. Cod’s texture is firm, flaky and moist if cooked properly. Pacific cods are moister than Atlantic cods.
