During pregnancy, expectant moms take all the efforts to make a healthy lifestyle and eat a well balance diet. This effort consists of exercising, getting enough sleep and eating nutrient dense food. Among the food groups that are part of our diet, fish is an excellent source of protein which is low in fat and helps promote brain development. Yet despite of its health advantages, along the way, you might have heard that eating fish may not be completely safe during pregnancy. There is some type of fish that could contain mercury that is harmful especially when you are expecting.
Eating fish has proven to provide a lot of health benefits- from the less fat protein to the omega-3 fatty acids that helps promote better brain performance and good heart health. Yet there is a continuing controversy that because of the polluted waters that we have, fish has the tendency to store into its body heavy metals such as methylmercury, a form of mercury that is highly toxic and detrimental to fetal health. Most fishes exposed to this metal are predator fish or large fishes that prey on small fishes. King mackerel, tilefish, shark and swordfish are some of the types of fishes that should be avoided during pregnancy. If you love tuna, you should also take an extra caution.
