Mercury in Fish Negatively Outweighs Positive Impact of Omega-3s

Little agreement exists as to whether low-level mercury (Hg) exposure causes damage to the central nervous system in adults. Although eating fish is associated with intake of methylmercury, researchers in this field have generally thought that the beneficial effects of a diet rich in long-chain, n-3 fatty acids (N3FA) can outweigh the cognitive neurotoxicity of mercury. This study clarifies the impact of Hg and intake of seafood on cognition. By Steven C. Masley, MD, FAAFP, CNS, FACN; Lucas V. Masley; C.
