Evidence Mounts That Eating Fatty Fish Helps Prevent Cognitive Decline

A group of 895 seniors who were given cognitive tests (i.e., memory, attention, organization and planning, etc.) were also asked how much omega-3 polyunsaturated fatty acids (PUFA) they ate in the form of seafood. The intake, mostly from canned tuna, was low. Dietary guidelines recommend eight or more ounces of seafood a week, but only 27 percent met or exceeded that level. Comparing omega-3 intake and test results after a two-year follow-up, U.S. researchers said those who ate the smallest amounts were the most likely to experience cognitive decline during the study period. The researchers concluded that intake of fatty fish such as salmon, tuna and trout certainly has health benefits, and may help prevent cognitive decline.
