At first blush, this finding appears contradictory because most of the mercury we consume comes from fish. "It seems a little paradoxical," said study co-author Dr. Susan Korrick, an assistant professor of medicine at Brigham and Women's. "But fish consumption doesn't necessarily correlate with mercury levels since you could eat a high amount of fish that are low in mercury." .... Fatty kinds of fish such as salmon, tuna, and sardines have higher levels of omega-3 fatty acids, which are thought to be crucial for cognitive function. All types of fish have a host of nutrients such as vitamin D, B-12, and iodine, which could play a role in brain development as well. While government agencies have advised pregnant women to limit their fish intake to no more than two six-ounce servings a week, Korrick said they might want to aim for three or four servings of low-mercury fish such as salmon, canned light tuna, haddock, cod, and shrimp. (Albacore tuna has more mercury, so consumption should be limited to six ounces a week.) The key is for pregnant women to avoid fish known to have high mercury levels, including swordfish, shark, tilefish, and king mackerel, Korrick added.
