The chemical form of mercury found in the brains of people who consume a high fish diet is completely different from the form of mercury found in the brains of those who were poisoned.
Researchers say industrial fishing could be exposing people in coastal areas and island nations to excessively high levels of mercury. It is estimated that people from 38% of countries examined may be exposed to higher methylmercury levels from fish than is deemed safe for fetal development.
Researchers report adults with higher prenatal exposure to methylmercury, as a result of fish consumption, did not experience faster cognitive processing or short term memory benefits following exercise.
