Cardiovascular Health

According to research, omega-3 fatty acids may help balance blood pressure and lower the risk of developing heart disease. To avoid cardiovascular problems, researchers recommend eating two servings of fatty fish per week, equivalent to 250 milligrams of omega-3 fatty acids. Omega-3 fatty acids also have anti-triglyceridemic, hemostatic, and anti-atherogenic properties, which may improve the structure and function of the heart.

Pacific saury and mackerel contain high levels of gamma-tocopherol, which has anti-inflammatory properties and benefits the cardiovascular system [1] [2].

However, pacific saury contains less sodium and saturated fat, so it is a better choice if you have cardiovascular problems.

Diabetes

To begin with, these fish contain no carbohydrates, which means they will not raise your blood sugar levels after eating.

Furthermore, studies suggest that fish oil may lower the risk of impaired glucose tolerance and hepatic steatosis. Omega-3 fatty acids from fatty fish and omega-6 fatty acids from linoleic acid are recommended for type 2 diabetes patients due to their positive effects on lipoprotein concentrations. Incorporating fish oil into your daily meal or diet can improve metabolic features associated with type 2 diabetes [3].

Mercury

The mercury in seafood depends on species and environmental pollution levels. In particular, King mackerel contains a high amount of mercury, but you can substitute it with Atlantic mackerel due to its low mercury levels. Pacific saury is a small fish that feeds on plankton and has lower mercury levels [5].
