We know that fish can be very nutritious and are packed with great nutrients
such as omega-3’s, the B vitamins and lean protein. But unfortunately,
fish can also have some unhealthy contaminants. Mercury is a contaminant
found in fish that can affect brain development and the nervous system. The
FDA has released guidelines for children, women who are pregnant and women
who are trying to become pregnant. These guidelines state that no more than
12 oz of low mercury fish should be consumed weekly. "Highest" mercury fish
should be avoided and "high" mercury fish should be kept to only three 6-oz
servings per month.
What does this mean for women who are pregnant but also trying to get some
of their much needed nutrients from the critters of the sea? It is all about
moderation. Recent information released in the American Journal of
Preventive Medicine says that no one should cut fish out of their diet
altogether. Fish contains too many healthy nutrients that are essential for
growth and development, especially in a pregnant mom and baby. There are 4
types of fish that should be on the list to avoid due to mercury levels.
These include: shark, king mackerel, swordfish and tilefish.
For information regarding other types of fish, the Natural Resources Defense
Council (NRDC) has released a list of fish and their mercury levels so that
people can be informed on what they are consuming. If you want to get more
detailed information about mercury levels and how much you personally are
consuming, you can also use the mercury thermometer to calculate your totals
.

Chart obtained from the Natural Resource Defense Council (NRDC); data
obtained by the FDA and the EPA.
Tuna mercury levels can be different based on the type of tuna and where it
was caught. The NRDC created the chart below as a guideline to how much tuna
can be eaten by children, pregnant women or women wanting to conceive,
based on their weight.

-caught的没有很多问题。在这个表上好像说是安全的，和shrimp\lobster一样。 |
