- Heavy Metal Fish
Written By South Centre Chiropractic Clinic & Summerside Chiropractic on December 19, 2016
I talk a lot about eating fish but there are many factors to consider in which fish you eat. There are environmental, omega 3 fat amounts and heavy metal amounts that should factor in on your decision. I will make this simple and list which ones are bad from a sustainability perspective, then those that have high mercury and then those that are the best from an Omega 3 perspective that are not on the other two lists.
Poor Sustainability: Chilean Sea Bass, Atlantic Cod, Crayfish from China, Atlantic Halibut, Mahi Mahi, Orange Roughy, Farmed Salmon, Shark, Imported Shrimp, Swordfish, Tuna
High in Mercury: Chilean Sea Bass*, Grouper, Mackerel, Orange Roughy*, Shark*, Sword Fish*, Tuna*
* denotes a double black list
Best in Omega 3: Anchovy, Herring, Sable fish, Wild Salmon,
Moderate in Omega 3: Arctic Char, Black Sea Bass, Striped Bass, Trout
I have read that some studies have shown only moderate levels of mercury in canned Tuna but those particular studies were funded by the people who sell canned Tuna! Strange how where the funding comes from seems to change the results! So depending on your priorities choose some fish and eat them three times/week for healthy choice.
Warm Regards to all, Dr. Darrell
