Most people agree that fish is one of the better meat choices to add to your diet. The Omega-3 fatty acids in fish have a variety of benefits to the human brain and body.
Unfortunately, however, not all fish is good for you. Particularly, eleven fish are of concern. They are:
- Some Bass
- Some Croaker
- Perch (Freshwater)
- Sea Trout
- Some Halibut
- Mahi Mahi
Daniel Barker notes that concerns about mercury contamination are what the fuss is about. Food Forensics notes,
“Because the oceans are polluted with it, methylmercury is typically found in fish and shellfish. The larger the fish and the longer the lifespan, the more mercury is accumulated; the most contaminated include tuna, swordfish, king mackerel, and shark. The EPA warns that nearly all fish are tainted with at least trace amounts of mercury. Some of the more health conscious grocery stores even include warnings on store shelves about methylmercury in tuna, and many recommendations caution people from eating tuna more and many recommendations caution people from eating tuna more than once a week (pregnant women are cautioned to eat it sparingly, if at all).”
The National Resource Defense Council (NRDC) helps to clarify the danger:
“You can’t see, smell, or taste mercury contamination in fish. Cooking has no effect on it, and you can’t avoid it by cutting off the skin or other parts of the fish. “
Fortunately, some fish fare better than the ones noted above. Those with the least amount of mercury contamination include:
- Croaker (Atlantic)
- Pacific Sole
- Freshwater Trout
Also, certain other foods are useful in removing mercury during digestion so that your body does not absorb this poisonous metal. Seaweed is very good at removing mercury, with nori seaweed typically removing 85% of dietary mercury, and one brand of dulse seaweed, was able to capture 99% of dietary seaweed in tests.
Foods containing insoluble fibers, such as fruits and vegetables are show the ability to capture mercury. Strawberries and alfalfa grass powder showed particular ability for this purpose.
Mercury is a real danger when ingested, but you can take simple steps to avoid the danger. If you choose to eat fish for it’s variety of benefits, we recommend that you take precautionary measures to ensure that the danger of mercury is not worse than the benefits that you would gain.
