Previously, people always thought that the fish oil contained in these fish could be used to inhibit heart disease. The researchers also warned that in addition to the above fish, some fresh and frozen tuna, marlin and red sea turtle should also be eaten less, because the mercury content of these fish is also "medium level". Warning: Excessive consumption of certain fish may increase the risk of heart disease. Suggestion: Eat more fish with high oil content but low mercury content, such as salmon.
