The Food and Drug Administration is encouraging women and children to eat more fish.
Researchers say many are missing out on the high-quality protein, vitamins, minerals, and omega-3 fatty acids fish can provide.
The FDA recommendation encourages pregnant women, those who are thinking about becoming pregnant, breastfeeding mothers, and children to eat 8 to 12 ounces of fish per week.
FDA researchers say the entire package of nutrients fish provide may be needed to fully benefit fetal and child development. They also suggest eating a variety of fish that are lower in mercury.
Most fish found in the grocery store fit the bill, including shrimp, salmon, canned light tuna, tilapia, catfish, and cod.
Researchers say to avoid tilefish from the gulf of mexico, shark, swordfish, and king mackerel, which have the highest levels of mercury.
