We want to eat fish - they are a healthy, nutritious, and full of good stuff for our bodies. Plus, they provide omega-3s and other such vitamins. But our streams are getting contaminated, and our fish farms are using un-natural means of growing fish... And along with all the healthy benefits of seafood, there are some problems with them as well.
The Test:
"After testing mercury levels in more than 1,000 fish over seven years, the USGS is warning Americans to limit the amount of large, predator freshwater fish they eat, such as large-mouth bass, pickerel, walleye and some catfish."
WHY? Harmful Effects of Mercury:
"Mercury is both formed naturally in the environment and is also caused by industrial pollution releasing it into the air. It is a heavy metal and toxic to the brain and tissues in the body. Mercury then gathers in streams and oceans and forms methylmercury in the water. When fish feed, they absorb the methylmercury, which is the type of mercury that is harmful, according to the EPA. Too much methylmercury could damage the nervous system and impair mental functioning. It is most harmful to children and pregnant women. Mercury poisoning has usually been associated with large ocean fish, such as the tuna used in sushi."
So, if we listen to these warnings and limit our fish intake, we may want to supplement with vitamins that will replace what we are not getting from a fish diet. But... remember... those "supplements" are made from fish. If the fish are contaminated, then so are your vitamins. Do the research to see if your omega-3s are pure, and how pure they are. It doesn't do much good to go through all the trouble of avoiding fish then popping supplements that are no cleaner. I'd recommend taking a look at the standards proposed by these guys, and check to see how other vitamin companies compare.
