Cardiovascular Health

Section reviewed by cardiologist Astghik Grigoryan

Halibut has almost 68 times the monounsaturated fat content and around 6 times the polyunsaturated fat content of cod.

Monounsaturated fats are known to decrease LDL cholesterol (low-density lipoprotein, also known as bad cholesterol) and, in turn, reduce the risk of heart disease (4).

Polyunsaturated fat also decreases bad cholesterol and thus protects from heart disease (5). A study has also shown that polyunsaturated fat consumption is correlated with a decrease in blood pressure in hypertensive patients (6).

Studies suggest that regular consumption of fish is associated with a lower risk of CVD (cardiovascular disease)-related mortality. While halibut typically contains higher levels of omega-3 fatty acids, both fish are low in saturated fats and cholesterol, making them heart-healthy choices when included as part of a balanced diet (7).

Cancer

A study showed that cod liver oil, a product derived from cod, stopped the growth of a tumor in rats (8). Moreover, daily use of cod liver oil for a year lowered the risk of death in tumor patients (9).

On the other hand, there are no studies showing a direct link between halibut consumption and cancer.

Vitamin B5

The recommended amount of vitamin B5 intake for adults is 5 mg daily (10). One hundred grams of halibut provides 0.25mg of vitamin B5.

Studies show that vitamin B5 might have beneficial wound-healing effects (11). Vitamin B5 might also have cholesterol-lowering effects and thus serve as a cardioprotective agent (12).

Vitamin D

Sufficient vitamin D consumption lowers the risk of some cancer types (13). Vitamin D also has an essential hormone production regulation function (14).

Folate

Cod contains 67% more folate than halibut.

Folate deficiency may lead to anemia. Low folate levels have been associated with an increased risk of cancer (15).

Phosphorus

Halibut is richer in phosphorus than cod. Phosphorus can be beneficial in the treatment of osteoporosis (16).

Anti-inflammatory Effects

Halibut is richer in polyunsaturated fats compared to cod. Omega-3 fatty acids have potent anti-inflammatory effects (17).

Mercury Levels

Cod and halibut contain mercury and may be neurotoxic if not consumed in moderate amounts (18, 19).

Pregnant women should also be aware of the mercury content of the fish as it may harm the baby (20).

California halibut have elevated mercury levels, while Pacific halibut, Greenland turbot, and Atlantic halibut have moderate levels of mercury (20). Alaska, US, and Canada Pacific cod have moderate amounts of mercury, while Atlantic cod is low in mercury (21).
