The United States Environmental Protection Agency's (EPA) Exposure Reference Dose (RfI) for methylmercury (MeHg) is 0.1 micrograms per kg body weight per day. The corresponding limit of blood mercury is 5.8 micrograms per liter. The restrictions apply to certain oily fish – "marlin, swordfish, shark and, to a lesser extent, tuna". [10]
Positives: The omega-3 fatty acid in fish is good for your health. People who eat fish regularly have a lower risk of heart attack. A vegetable-heavy diet is associated with a lower risk of heart ...
[9] [10] Eating about 140 grams (4.9 oz) of oily fish rich in omega-3 fatty acids once per week is a recommended consumption amount. [9] [10] Increasing intake of omega-3 fatty acids may slightly reduce the risk of a fatal heart attack, [10] but likely has little effect on the overall number of deaths from cardiovascular disease.

Oils from these fish have a profile of around seven times as much omega−3 oils as omega−6 oils. Other oily fish, such as tuna , also contain omega−3 in somewhat lesser amounts. Although fish is a dietary source of omega−3 oils, fish do not synthesize them; they obtain them from the algae ( microalgae in particular) or plankton in their ...
Oils from these fishes have around seven times as much omega−3 as omega−6. Other oily fish, such as tuna, also contain n−3 in somewhat lesser amounts. [1] [65] Although fish are a dietary source of omega−3 fatty acids, fish do not synthesize omega−3 fatty acids, but rather obtain them via their food supply, including algae or plankton ...

[16] Australian standards once required cans of tuna to contain at least 51% tuna meat, but these regulations were dropped in 2003. [17] [18] The remaining weight is usually oil or water.
The proportion of omega-3 to omega-6 fatty acids in a diet may have metabolic consequences. [2] Unlike omega-3 fatty acids and omega-6 fatty acids, omega-9 fatty acids are not classed as essential fatty acids because they can be created by the human body from monounsaturated and saturated fatty acids, and are therefore not essential in the diet.
