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.
