Eating Low Mercury Seafood and Fish

It's very important to eat a good quantity of fish for the omega oils they provide. Fish are also usually zero carb, making them perfect for a low carb / Atkins diet. However, watch out for mercury!

Mercury is a heavy metal that exists in all seafood (not in freshwater lake fish). Some types of fish tend to absorb mercury more readily than others. You should in general try to stay with low mercury level fish, eating these fish twice a week. Keep the higher mercury level fish for only once a month or once every two month consumption.

Note that the mercury tends to gather in the fat of the fish, so avoiding the fat can help somewhat. Also, smaller fish tend to absorb less mercury than larger ones.
