The FDA released revised information for pregnant women about the benefits of fish as part of a healthy diet. The advice promotes the science-based recommendations of the 2015-2020 Dietary Guidelines for Americans. The Guidelines recommend that all people age 11 and up eat at least 8 ounces (two 4-oz servings) of fish or shellfish per week.
In the FDA release, pregnant women and those breast feeding are advised to eat 2 -3 servings of fish per week from choices that are lower in mercury. The release includes a chart with fish choices that are identified as "best," "good," or "choices to avoid." Examples of fish to avoid because of higher mercury levels include king mackerel swordfish and bigeye tuna. See sources list at the bottom of this article to link to the complete list of recommendations, "Advice About Eating Fish."
The chart below presents eight of the ten most popular kinds of seafood consumed in the U.S. These eight are also on the FDA's "best choices" list because they contain lower levels of mercury. The second column identifies the best "ocean friendly" sources, including regions of the U.S., world, and/or fishing methods, while the third column has "good" alternative ocean friendly sources. Buying more sustainable seafood helps put less strain on the fish populations.
