A major side effect of eating too much canned tuna, says science
Know your fish so that you do not be sick of the sea chicken.
For many of us, our pantries are stored at the gills withcanned tuna. It is both inexpensive and a good source ofBelly filling protein. In addition, this does not require any cooking, not even a plate - just a box opener and two slices of bread. Bingo! You have a lunch, a snack or a dinner!
Since this is a source also practical of protein, you may see that you eat a lot of Thon-three, four, five times a week, maybe? Depending on how much and, especially what kind of tinned tuna you eat,You can do too much too much, which potentially leads to aSide Fish Effect called mercury poisoning. But before you deceive, read it and check these6 ways to eat fish can help you lose weight.
The canned tuna contains mercury, so eating too much of this can lead to poisoning on mercury.
The consumption of ocean and crustaceans represents more than 90% of the human exposure to mercury in the United States and the tuna harvested in the Pacific Ocean represents 40% of this total exposure, according to a study ofEnvironmental Health Outlook.
Mercury in the tunes of coal electricity generation and other human industrial activities settles in lakes, rivers and oceans where it is consumed by marine life. But mercury in the oceans is also a product of organic carbon decomposition of nature, according to scientists reporting in the journal.Global organic cycles. When the mercury enters the water, anyway, the microorganisms transform it into a very toxic form called methylmercury which accumulates in the fish flesh we eat. MethylMercury bioaccumulated in large predators, which is why bigger fish like tuna are more risky to eat than, say, sardines. (In touch:The best fish n ° 1 to eat, according to a dietician.)
How it is possible to obtain high levels of methylmercure in the body.
"All fish have a certain level of mercury, but this level varies considerably; canned tuna has relatively high mercury levels so that its consumption can potentially become harmful above three portions per week," saysAndrea Paul, MDmedical adviser toLighting laboratories.
Almost everyone has a small amount of methylmercury in their blood that is lower than levels that can trigger health effects, according toUS Centers for Disease Control and Prevention Data (CDC). But MethylMercury is a powerful neurotoxin, so that too much fish can cause intoxication on mercury. Symptoms include itching or feeling of pins and needles in toes and fingers, muscle weakness, coordination, speech and audition and reduced peripheral vision. High levels of mercury in pregnant women can result in central nervous system disorders in their babies.
How to stay safe.
The Food & Drug Administration and Environmental Protection Agency recommend to women and children (over 10 years)eat two to three portions (8 to 12 ounces) of a variety of fish and crustaceans every week because seafood is aGreat source of omega-3 fatty acids, which are essential to the development of the brain in good health. Both agencies recommend choosing low mercury seafood and have created aadvice graphic showing how many times eating 60 different types of fish by designating them as "best choices" (eat 2 to 3 times weekly), "good choices" (eat 1 serving per week) or "choice to avoid" (highlighting the fish containing The highest fish levels of mercury).
The popular white canned tuna (yellowfin) makes the list of 4 oz-serving-per week, because it is a larger fish that contains larger amounts of mercury than fish on the "best choice" list . The "light" tuna canned (especially the tuna of Lisjack) wins a place on the "best choice" list because it is a smaller fish that is usually lower than mercury.
But an environmental health advocacy organization called environmental working group states that government guidelines can put women at risk. In aNational studyEWG recruited 254 kindergarten age women around the nation that pointed to eat as much or more fish than government suggestions. The researchers tested samples of their hair because mercury accumulates it and reflects the level of mercury in the body. Nearly 30% of women studied had on the secure mercury limit of the EPA and nearly 60% had more mercury than a stricter limit set by two European institutions. The TEA estimates, including the lightweight tuna canned on the "best choices", "the" lower mercury "category is false since the Lagly" is an important source of mercury in the female regimes, "he says. On the Base of a food questionnaire, tuna paid nearly 40% of mercury ingested by the participants to the Mercury Policy Project Study, the EWC says.
If you want to reduce the canned tuna, try salmon, a low mercury fish on the "best choice" list of the FDA. And here is a delicious recipe for a Salmon Fish Taco Bowl . Enjoy!
