Some Women and Children Need to Limit Their Consumption of Tuna
Tuna is the Favorite Fish of Most American's
A serving of 2 . 5 ounces of white tuna contains more mercury than the recommended safe amount suggested by the Environmental Protection Agency . Other contaminants found in some fish have been linked to cancer and reproductive problems . Heavy metals accumulate in tuna and other fish in the toxic form of methylmercury , which comes from mercury released by coal - fired power plants , other industrial sources and natural sources such as volcanoes .
Benefits of Fish
Fish are rich in protein , vitamin D and omega - 3 fatty acids , which are needed to lower our risk of heart attack and stroke . They also help prevent certain cancers , dementia and eye disease . Omega - 3's are important during pregnancy to help the development of the brain and the visual system of a fetus .
Low - mercury fish
Fortunately other low - mercury fish are available . Some of the most popular sea - foods are salmon and shrimp . Alaskan salmon , usually sold in cans tends to be lower in contaminants than some other sources of fish . Other low - mercury fish are farm - raised clams , pink shrimp from Oregon , sardines from the U . S . Pacific and tilapia farmed in the U . S . Farmed fish are plentiful , well managed and harvested under strict regulations .
Safe amounts of consumption
Women of childbearing age and children may consume up to 12 ounces of light tuna or other low mercury seafood within one week .
Children under 40 pounds should limit their weekly consumption to 4 ounces of light tuna or 1 . 5 ounces of white albacore tuna .
Children over 45 pounds could consume from 4 to 12 ounces of light tuna or 1 . 5 to 4 ounces of white tuna per week .
Pregnant women should avoid all tuna consumption and those planning to have children should limit their consumption of light or white tuna to 4 ounces per week .
Men and older women may consume 14 . 5 ounces of light tuna or about 5 ounces of white tuna per week . However , those who choose to consume more fish should choose low - mercury types of fish .
