Working at the library and saw this. Thought I should post it here in case anyone isn't aware:

Crawford [deputy commissioner of FDA] listed the three-part guidelines for women and children as:

_ Do not eat shark, swordfish, king mackerel or tilefish because they contain high levels of mercury.

_ Eat up to 12 ounces — two average meals — per week of fish that are lower in mercury, such as shrimp, canned light tuna, salmon, pollock and catfish.

_ Check local advisories to determine the safety of fish caught by family and friends. If no such advice is available limit such fish to one six-ounce portion a week and don't consume any other fish that week.

Children should be served smaller portions than adults, the agencies said, but they did not offer any age-specific guidelines.

While the report praised the benefits of light tuna it said albacore tuna should be limited to one serving a week because these older fish can be higher in mercury than the young tuna that go into the light version.

FDA scientist Dr. David Acheson said the method of preparing food makes no difference in its mercury level. He also noted that processed fish such as fish sticks and fast-food fish sandwiches are usually made of pollock, which is low in mercury.

People not singled out in the guidelines, such as men, should include fish in their diets because of its health benefits including being a good source of protein and heart-beneficial omega-3 compounds, said Crawford. Fish has become increasingly popular in recent years because of these benefits.

The American Heart Association (news - web sites) recommends that people eat fish at least twice a week, even more often for those diagnosed with heart disease.

This is good advice for anyone who wants to cut the mercury out of their diet. Mercury goes into the body and is NOT processed (i.e. it builds up). The reason why women shouldn't eat fish containing mercury is that it could affect the fetus were they to become pregnant, and pregnant & nursing women should watch their intake of mercury with special care so as not to pass it on to the unborn or very young child.

As a general rule of thumb, if you want to cut down on your mercury intake, try not to eat fish that eat other fish. :D

Thank you for the article Kinael, I've actually been looking for more information on this topic.

Add - PS, salmon is good for you to eat up to 2x/wk because it provides a lot of essential amino acids.

Hm... this sounds as if the mercury in our bodies will always increase, or am I reading MacPhisto's comment wrong?

You're welcome, Mac and raine! D:

I'm pretty sure Mercury within the body will be removed through some means . . . or else it wouldn't really make sense for the FDA to set a limit, and not an outright ban. An over-exposure will do harm, in any case. But I suck in all things science, so someone else should fill this in instead of me :X

That is what I have heard and read, Rwen, but I'm not actually certain that it stays around forever. I know that it does get deposited in your body and that the human body is unable to process or absorb lots of mercury. Whether we get rid of it in small quantities as a waste product.... I don't know for sure.

Anyway the quantities of mercury that a person eats in their lifetime is probably relatively small that you wouldn't have to worry about it. Unless you were a very tiny person like a fetus or a baby XD

Add: here's something interesting about mercury poisoning ...
http://www.european-digest.com/ecd01/docs/digest17.htm

This one talks about the toxicology of mercury. It confirms that it is bioaccumulative.
http://www.mercola.com/2003/apr/9/mercury_toxicity.htm

This article says that fish and other animals take in mercury much faster than they can get rid of it, so maybe it *does* flush out, it just takes longer to get out than it does to get in.

No shark? Shark's fin soup is too good to pass on though, doh. My Japanese teacher was actually talking about this to us a few weeks ago since Japan is an island country after all and eats a lot of seafood.

I eat fish every day. I hope that doesn't imply I'm gonna get mercury poisoning too.

After all, I am fili..

How often do people die from mercury poisoning?

I'm thinking there's a better chance you'll die from malnutrition and lack of the minerals that fish have rather than overdose of mercury. Just eat it. And be happy. And live your life. 0o;

There were a few outbreaks of mercury poisoning in recent history around the world (see some of the links I posted for more). Most of them were due to eating contaminated fish from contaminated waters (shoreline pollution etc.). But really unless you are eating contaminated fish (fished in polluted water), or you are pregnant, then I don't think that eating fish will hurt you, even if it has a teeny bit of mercury in it.

... so this means my daily intake of sushi and sashimi from the all you can eat japanese buffet is OK, right? T_T

why does it affect to pregnancy?

It affects pregnant women because whatever they eat also goes into the fetus. A tiny bit of mercury isn't harmful to an adult because adults are physically larger, but even a trace amount of mercury could be harmful to a fetus who is small and still developing. Basically, the proportion of mercury to body size is much greater for a fetus than for an adult.
