Children should eat light tuna no more than once or twice a month, depending on their size, and they should never eat albacore tuna, to reduce their exposure to mercury, a research and advocacy group says in a report.
Those limits apply to all children’s meals, at school and home, according to the report from the Mercury Policy Project, based in Montpelier, Vt.
Studies link excessive mercury exposure to impairments in cognition, memory, attention, language, and fine-motor and visual-spatial skills. While most research has focused on such effects on fetuses, the Mercury Policy Project said mercury also affects children’s developing brains.
